Motorola Solutions CTO: Public Safety Will Be Transformed By Data-Driven Communications Read more at http://www.techweekeurope.co.uk/networks/broadband/motorola-solutions-public-safety-data-197830#WCOWXTjdibreBRqI.99

The good old walkie talkie will still have a place in most businesses, but Motorola being a technology company they are always innovating, they are underpinning their future communications on data, currently date networks cannot cope with this but as the technology grows, Motorola will be able to produce handsets, motorola accessories and communications that will seamlessly use this without any problem, we look forward to the future. 

Motorola Solutions CTO Paul Steinberg explains how data and enhanced communications can make cities safer â€" even if they’re not smart just yet

As CTO of Motorola Solutions (MSI), Paul Steinberg says he has three broad remits.

paul-steinberg-motorolaThe first is to advance the company’s technology with his team of engineers and data scientists, the second is to drive its patent strategy (“What patents we get and what we do with them”) and the third is to invest in startups so MSI can get access to something it doesn’t have.

“It keeps you humble because there’s always someone else doing things faster and better than you,” he tells TechWeekEurope.

Public safety

Motorola Solutions now only deals with public safety communications systems. It was spun off from the Motorola Mobility handset business that was sold to Google (and later Lenovo) in 2011 and sold its handheld computing division to Zebra Technologies in 2014.

This might seem like a very narrow focus but it’s a market in which the present day Motorola senses a great opportunity as emergency services update their infrastructure to improve service and cut cost.

In the UK, MSI is working with EE to help deliver the £1 billion Emergency Services Network (ESN) â€" a 4G platform that will allow for data-enabled services alongside critical communications â€" and save the government £1 million a day

These upgrades will power what MSI sees as the big trend in public safety: the coupling of communications with data analytics, a vision it recently outlined at Critical Communications World (CCW) in Amsterdam.

“[Mission critical communications are] every bit as important as they have been and we expect [them] to be tomorrow,” explains Steinberg.

“Mission critical intelligence brings in connecting things â€" data. It becomes more about context and situational awareness. The investments we’re making are more in that direction.

“One of the things we’ve been working on is the connected first responder. What we did was we built a context engine that’s at the heart.”EE 4G (3)

Context engine

The ‘context engine’ built by MSI brings together various different inputs. For example, Bluetooth connectivity can unite weapons, body sensors and imaging equipment to give a police force a greater overview of a situation.

Steinberg explains a scenario where if the context engine detects a weapon has been fired and a policeman is not at a station or at a firing range, their video camera will automatically switch on. Other situations could give a paramedic of firefighter additional information, possibly through wearable technology.

“Why did we do the Context engine? ‘Eyes open, hands free’: keep focussed on what you’re doing and keep your hands available to do what you need to do,” said Steinberg.

“We envisage this working as an ecosystem with well-designed interfaces around the core context engine. We see ecosystem partners offering applications and hardware. And some pieces of those we will offer as Motorola. We see it increasingly as a software problem.”

Steinberg favours acquisitions as a way of advancing his goals and MSI has venture capital operations to fund the third part of his remit. MSI monitors the development of numerous early stage companies with a view to boosting its own business.

Motorola Solutions public safety (3)“[Takeovers] give us technology or a skillset that we can’t do properly [ourselves],” he explains. “If the concept looks like it has legs, that’s when we make the decision. In some cases we don’t proceed.”

Sometimes the target is more established. MSI has bought Airwave for £817 million, a move which it is believed will help accelerate the transition to next generation systems. Airwave currently powers the pre-ESN communications capability of the UK emergency services and Steinberg sees the acquisition as a method to migrate customers rather than innovate.

“It brings us another data point but it doesn’t really change how my team works,” he says. “It’s a company that helps us ensure we have an orderly migration.”

Smart cities and smart vehicles

MSI says the Context Engine and its vision of data-supported communications will be strengthened by the parallel development of smart cities; even if it’s too early to have any impact right now. Steinberg describes ‘shotspotter’ technology capable of detecting when and where a gunshot is fired, aiding emergency services, and believes smart cars will also play a role.

“I think as the city becomes smarter, we can benefit from the environment,” he predicts. “We can fuse that together and help facilitate real time decision making. The next mobile platform is the vehicle. I think that will create some interesting opportunities for us.”

But the very nature of emergency services means technological jumps are not to be taken lightly. A technical hiccup can mean the matter between life and death and although political reasons might have delayed the transition to LTE, concerns about reliability will have played a role too.

Steinberg agrees and is adamant that no matter what advances are made, MSI will not jeopardise the basics.

“The foundation of our business is communications and it always will be,” he states. “Making sure our platform is resilient, usable and mission critical in harsh environments while layering on this intelligence.”

LeBlanc: Protect your hearing it is irreplaceable

This is an excellent story about how hearing protection is sometimes be essential, and when you’re on the shooting range it has to be vital. But it is important to get the right set of headphones that will protect your hearing sufficiently. Lessons can be learnt from this excellent case study.

There is no doubt that we all take our senses of sight, smell, and hearing for granted as long as we are strong and healthy and everything is working well. When we are young we tend to believe that we are indestructible and readily adopt the idea that “it will never happen to me.” Consequently, we can develop some bad habits and be a little loose when it comes to preventative measures for almost anything.

I know because that was my attitude at thirty years old when my eye doctor made a comment in passing that my eyes were perfect, but the chances are I would be needing reading glasses by the time I was 50. I scoffed, but you could almost have set your watch by it because by the time I was in my late 40’s my arms started to get shorter when it came to reading, tying on fishing lures and other things that required scrutiny up close. At 50 I was wearing reading glasses.

Growing up I never bothered too much about wearing ear protection. When I was plinking it was with a .22 rifle that only put out a little noise if you were the shooter so the thought of hearing protections seemed ludicrous. When hunting I do not know if I have ever heard my firearm discharge and beside that unless I was dove hunting I seldom shot too many shots anyway.

The change of heart came when I started shooting on an indoor range, while in the Air Force. I noticed after shooting a few rounds with my .22 caliber, Ruger Single Six that my ears would ring for a while afterward. One night a grizzled old Master Sargent suggested I wear ear protectors or take a chance of damaging my hearing. I took the recommendation to heart and have been wearing them ever since. The result has been that after many years of shooting .22’s, large caliber handguns, rifles and shotguns my hearing is still intact and working well.



Shooting is not the only activity that can cause hearing problem as any loud noise can damage your hearing. The intense vibration caused by loud noises can injure or destroy the hair cells inside the cochlea, so they no longer function to transmit nerve impulses to the brain. If that happens, you will experience hearing changes.

Hearing protection is needed anytime one is exposed to sounds above 80 decibels (dB). Normal human conversation runs about 30 to 35 dB. At its peak level, the sound of a 12-gauge shotgun is about 140 dB. 9mm runs around 159 dB and a .38 special with a six-inch barrel is about 156 dB, a .22 LR pistol with the same length barrel 140, an M-16 is about 154, a .45 ACP pistol is 155, and a .357 Magnum revolver is 164. All of them are around double the safe sound level. Just to be on the safe side I used to wear muff type hearing protectors and usually ear plugs also when on the range.

For range use today there is an array of muff style hearing protectors. The new style that I now use have not only hearing protection, but also hearing enhancement. The controls on each ear can be tuned to match your individual optimum hearing and increase the volume up to eight times normal. So when the range master gives a command or when you are speaking with a companion on the shooting line you can speak in a normal voice and hear them as well or better than without the power muffs. Yet when you shoot the sound activated compression circuit reduces the sound from the shot to a noise reduction rate of 24dB.

This is very important on a shooting range because I have missed range commands in the past from the range master simply because I could not hear them through my hearing protection.

The new muffs I use are from Walker’s but they offer many other styles in their Game Ear series. These are unlike the muff style protectors as the bulk of the unit fits behind your ear with an earpiece that fits inside your ear, the unit weighs less than one fourth of an ounce and can be used with or without glasses. These too can be fine-tuned to your specific hearing, allow you to turn the volume up to magnify sounds from five to seven times and still reduce the sound of the shots to a rating of 29dB.

The ability to custom tune the devise to your hearing as well as adjust the volume up on these models will enable the hunter to more readily pickup games sounds in the woods. Sounds like a squirrel jumping through the trees or when their belly slaps a tree when they jump from one to another. It will help the hunter pick up the minutest sound of a deer brushing by limbs or the whisper of them walking through leaves or disturbing a rock.

So now there is really no acceptable reason not to wear hearing protector and if you get a good set it may even enhance your chances of bagging some more game.

Motorola Solutions’ digital two-way radio technology enhances mission-critical communications at Munich airport

Motorola solutions are a company well known for their robust two way radios and for building world class communication structures. Improving on the current TETRA system with an IP dispatch console and piloting the WAVE system, that allows a phone app to connect to the radio system, for communicating of site. You can read more about what Motorola are doing for Munich below and you can find the original article here.

Motorola Solutions has received an order to implement a comprehensive update and extension of its existing TETRA digital two-way radio system at Munich Airport.

The newly modernized communications infrastructure ensures greater connectivity, interoperability and collaboration between various business and operational functions at Germany’s second largest airport. Motorola Solutions will also provide services for ensuring smooth operations.



Within the framework of the TETRA radio network refresh, Motorola Solutions is equipping the airport with a new MCC 7500 IP Dispatch Console. The comprehensive, scalable solution enhances the IP architecture to ensure optimum call set up and availability. It will also allow Munich Airport to expand its communications infrastructure in the future without interrupting existing services. As well as this, Motorola Solutions will implement two TETRA base stations for improved TETRA radio coverage in the terminal buildings.

Alongside the improvements to the TETRA system, the airport has started a pilot project for the potential introduction of Motorola Solutions’ broadband push-to-talk (PTT) platform WAVE. The goal of the installation is to ensure that airport staff can communicate, no matter which device or infrastructure is being used. The powerful PTT solution WAVEâ„¢ Work Group Communications provides airport authorities with secure and reliable communications beyond TETRA radio â€" including broadband devices and networks â€" to enable greater workforce connectivity, interoperability and collaboration. WAVE connects the TETRA system used by administrative staff with service management employees who join the broadband platform via smartphones, computers, other radios or telephones, meaning that staff across the airport can communicate with one another from virtually any location.

“We have been working with Motorola Solutions’ TETRA two-way digital radio system since 2007,” said Michael Zaddach, head of the IT service division at Flughafen München GmbH. “The update of our TETRA infrastructure enables us to further improve our communications in airport operations and make our processes even more efficient.”

“We are collaborating closely with Munich Airport to provide a future-proof TETRA digital two-way radio network,” said Klaus-Dieter Drossel, sales director for key accounts, Motorola Solutions Germany GmbH. “We are also pleased that Munich Airport is testing our broadband push-to-talk platform WAVE, and we are certain that it will enable airport staff to work together more closely, no matter which device or network they use.”

Far offshore windfarms present communications challenges

This is an interesting article debating the different types of communication that can be used over a long distance, and as they distance moves further and further, the different types of communication drop off or become part of an infrastructure. As engineers battle with this problem, knowledge of how radio frequencies and applications becomes paramount.

As offshore windfarms are built further and further from land, alternatives to conventional VHF communications are going to be required

A cornerstone of any major project is clear communication between all parties. As we move windfarm construction further offshore, maintaining efficient voice and data communications becomes essential. With many projects now being constructed beyond the range of VHF radio and cellular telephone, such as a Gemini or Dudgeon offshore windfarms, crew transfer vessel (CTV) operators and their clients are experiencing challenges achieving practical and affordable offshore communications. My experience on two far offshore projects in the last 15 months has shown that creative thinking can work together with existing equipment such as TETRA radio to reduce the risks and stress that poor communications can generate.

Communication solutions on offshore windfarms depend on the phase that the operation is in, the size of the project and the distance from shore. Many smaller, older windfarms rely on VHF radios to communicate between shore and vessel and shore/vessel and work team on the turbines. However, VHF is limited in range being a line-of-sight system, and the signal has trouble penetrating structures such as wind turbines due to the Faraday cage effect. Conventional cellular telephone coverage is also possible on nearshore sites, with some windfarms installing a cellular mast within the windfarm. Vessels at anchor off the Dutch port of IJmuiden can thank the windfarm industry for good connection when waiting for a pilot if they have contracts with the provider KPN.

When moving further offshore, luxuries such as a cellular mast will not be installed during the construction phase, and it is most likely that VHF radios will not be sufficient. It is common for the developer to install a TETRA radio network â€" similar to those used by national emergency response services such as police and fire departments.

TETRA, or terrestrial trunked radio as it is properly termed, is a secure network allowing one-to-one, one-to-many and many-to-many communications. This means that the marine controller can speak directly and privately to one party or to the entire offshore spread depending on what is needed. It transmits on a lower frequency than VHF so covers a greater range. This still is not enough to cover the distances experienced on far offshore windfarms. If multiple base stations are used, each base station can then automatically rebroadcast a message thus expanding the network coverage. On a recent construction project, it was found that there were communications blackspots in the area of the sea passage from the base port to the site. This was later eliminated by fitting full base station units rather than just handheld transceivers on the CTVs. The CTVs then became vital links in the communications network and ensured the blackspots were reduced or eliminated altogether.

TETRA has many other advantages, including the ability to penetrate the tower of a wind turbine, and calls are not dropped when moving between base station carriers due to the network configuration. This is especially important if vessel-carried base stations are relaying far offshore. The network is also secure, which ensures that commercially sensitive information cannot be intercepted. With the one-to-one mode, it also means that managers can have detailed conversations on sensitive subjects.

However, anecdotal information received from vessel crews in the field appear to indicate that TETRA, although a good system, is not foolproof. One vessel master reported that, after 15 months on site, they still had blackspots with TETRA and sometimes have to use the cell phone application WhatsApp to request that turbines be started or stopped so that he can land a team.

TETRA does not solve the operational problems experienced by vessel-operating companies who require frequent voice and data communication with the CTVs to ensure a smooth delivery of service. As most sites far offshore are outside of cell phone coverage and clients demand that daily reports are issued on time, creativity is needed. There is a simple solution that could solve all of the communication problems far offshore â€" installing VSAT satellite communications on each CTV, which allows instant telephone and data transfer.



However, the practicalities of chartering in today’s windfarm industry eliminates this option, as the client will not want to pay for installation and operation, and a vessel owner cannot afford such a luxury. Charterers therefore need to make a decision: either they assume responsibility and the costs for practical workable satellite communications on their vessels or look for practical alternative solutions to deliver what is needed far offshore.

One practical solution to maintain communications between the marine co-ordination centre and vessels is to step back a generation and use medium frequency/high frequency single side band radios, which are common equipment on larger CTVs and is standard on service operation vessels (SOVs) or installation vessels.

When used in conjunction with the digital selective calling (DSC) function of the GMDSS standard, voice communications can be maintained at long distance without operating cost. Unfortunately, current guidance for the marine co-ordination in windfarms as found in the G9 Good practice guideline: The safe management of small service vessels used in the offshore wind industry does not yet consider marine co-ordination and communications in far offshore windfarms.

Another practical solution to improve data communication is to install powerful WiFi antennas on the decks of SOVs and other major offshore assets to allow CTVs to have internet access when they are in close proximity. CTVs can then download passenger manifests and weather reports and upload the daily progress report and synchronise planned maintenance and email systems.

CTVs spend considerable time in close proximity to the SOV during passenger transfer, bunkering or waiting for the next assignment, and it is relatively easy to set up the computers to connect and synchronise without operator input, thus reducing the risk of distraction. SOVs should be designed with space for CTV crews to use as a secure office so that laptops can be left connected to the network. In this way, crews can have two computers and prepare work when on shift, transfer via a data stick and upload when they go off shift.

One of the most effective tools that we have identified is WhatsApp, which seems to require very low signal strength to connect and transfer brief messages. On recent projects, we have found that most vessel/office communication occurs in this medium, including fault finding and incident reporting and investigation. Crews have found it quicker to video a CCTV system playback and send via WhatsApp than download the CCTV video and send it via a file transfer service. As synchronising an electronic planned maintenance system offshore is very time consuming, our superintendents have taken to sending the worklists via WhatsApp to the vessels who then confirm back with text or images when a job is complete. The superintendent then does the PMS administration from their office with the advantage of high speed network connections. Experience with WhatsApp has led me to believe that agile, low data applications will form part of the future of offshore communication.

Far offshore projects have moved from planning and dreaming to reality. However, effective and cost-efficient communication solutions have not moved with them. Like most challenges with far offshore windfarms, there is no single solution, but experience has shown that, with creativity and flexibility, projects can communicate with their teams and operators can manage their vessels.

Better equipment earlier on in the construction phase, such as MF/HF radios in the MCC and on the vessels, TERA base stations on the vessels and open deck WiFi on construction assets will all assist in improving safety and reducing stress while ensuring that unnecessary costs are not incurred.

Ericsson first to deliver 5G NR radio

We are seeing a new era in communications at the moment, the move from tetra and RF to the mobile network. The uk’s emergency services will be moved over to EE’s ESN system slowly until 2020 using Motorola kit designed particularly for the technology. The natural evolution is 5G, which we won’t see for many years, but Ericsson have taken the baton and are running with it.



  • World's first commercial 5G New Radio (NR) radio for massive MIMO and Multi-user MIMO coming in 2017


  • New additions to Ericsson Radio System address key requirements of 5G, in today's networks


  • Pioneering Industrialized Network Rollout Services solution facilitates complete rollout from configuration to verification in a single visit




Ericsson (NASDAQ:ERIC) is commercializing the world's first 5G NR radio for massive MIMO, with the first deployments coming in 2017. Together with the Ericsson 5G Plug-Ins announced in June and Ericsson's already commercially available Radio System Baseband 5216, which currently powers Ericsson's award-winning Radio Test Bed, Ericsson is first to deliver all components of a 5G access network.

Tom Keathley, senior vice president, Wireless Network Architecture and Design, AT&T, says: "As we accelerate toward 5G, it's beneficial to have a flexible radio platform that can be deployed not only for LTE, but also versions of future 5G NR standards."

AIR 6468 combines advanced antennas with a large number of steerable ports to enable 5G technologies of beamforming, Massive MIMO and -- building on that -- Multi-user MIMO, initialized as MU-MIMO. These capabilities improve user experience while enhancing the capacity and coverage of the network and reducing interference. The new radio provides LTE support as well, so it is applicable in today's networks.

Huang Yuhong, Deputy Head, China Mobile Research Institute (CMRI), says: "Massive-MIMO, also known as 3D MIMO, is an important milestone in China Mobile's technology roadmap from 4G to 5G. We are very happy that Ericsson's new radio product is coming to market soon to meet our needs and enable us to integrate 5G technologies into our existing networks."

A host of new additions to the Ericsson Radio System are also coming that address key 5G requirements, in today's networks.

Daniel Staub, Head of Joint Mobile Group, Swisscom, says: "On the road to 5G, we will continue to invest in LTE advancements that will become part of our 5G networks. For us, it is key that Ericsson has chosen to focus on advances that will support us in this evolution. These enhancements will further improve the customer experience."

Additional new Ericsson Radio System gear addresses 5G concepts



  • Three new radios support Gigabit speeds for LTE and provide further flexibility in design: Radio 4407 and Radio 4412 enable 4x4 MIMO in one radio unit for FDD and TDD mode respectively, and Radio 8808 for advanced TDD beamforming applications


  • Addressing both the need for unlicensed spectrum options and the growing emphasis on small cells is the Radio 2205, a micro solution on unlicensed spectrum that is fully integrated in Ericsson Radio System, using the same baseband and network management


  • Two new baseband units support the growing need for densification: the outdoor micro Baseband 6502 and macro Baseband 6303 with Ericsson Rail System mounting for flexible site builds


  • Addressing interference issues in dense builds, Baseband P614 enables new band activation on challenging sites by mitigating Passive Inter Modulation, referred to as PIM mitigation, from static and dynamic sources both inside and outside the antenna system


  • Spectrum optimization is a growing need and Uplink Spectrum Analyzer is an Ericsson-unique software solution to remotely identify external interference without the need for costly measurement equipment and site visits


  • Exclusive to Ericsson is instant power sharing, used in the wideband Radio 2242. This capability allows power to be instantly shared between carriers, standards and bands, optimizing the use of radio resources


  • Cloud RAN will be an important 5G network architecture and Baseband C608 provides high-performance switching in Elastic RAN deployments






Peter Jarich, Vice President, Consumer and Infrastructure Services, Current Analysis, says: "Mobile operators, today, are clearly focused on the race to 5G commercialization, while also continuing to invest in their existing LTE networks. With a new 5G radio and LTE offerings which echo key 5G concepts - small cells, licensed-unlicensed band combinations, Cloud RAN, network densification, spectrum optimization - Ericsson's new portfolio additions and Ericsson Radio System innovations provide a compelling way forward."

To support new network builds, Ericsson has created the industry's first Industrialized Network Rollout Services solution. The Network Deployment Delivery Platform coupled with Ericsson's pioneering process facilitates the complete configuration, installation, integration, shakedown and handover of a fully verified site, ready in a single site visit.

Arun Bansal, Head of Business Unit Network Products, Ericsson, says: "Ericsson has driven innovation in every generation of mobile technology and now we are set to over-deliver on an aggressive promise. We are introducing the new hardware that 5G Plug-Ins, announced in June, will run on, so that the first operators can start to deploy 5G infrastructure.  And, we are also launching innovations that improve both the performance and efficiency of today's networks using concepts that will evolve into 5G."

Could hearing loss be a hidden cost of gaming?

Is this is a real problem? Do you use a set of headphones whilst gaming? This article has information on how damaging wearing gaming headphones is and what the future impact might be. Read this, examine how you use your headphones and get on with life…



According to the Q1 2016 GameTrack report, 18.8 million people between the ages of 6 and 64 game and those between 11 and 64 spend an average 8.8 hours per week doing so.

 Amongst Gamers the largest group is 15 to 24 year old males who are most at risk of permanently damaging their hearing. This group spends the most amount of time gaming and are also the most attracted to the “loud” games. Furthermore a majority of them live in a shared accommodation and use headphones so as not to disturb others. This group also the most likely to take part in other activities which can be harmful to their hearing such as listening to music through headphones, going to gigs and festivals, and nightclubs.

 Unfortunately the price of their enjoyment could well be significant and permanent hearing damage. Whilst there is clearly a risk to the Gamer, it could transfer as a liability to the games companies in the form of legal action relating to their duty of care.

 The first significant step is to make Gamers aware of how much sound exposure they are experiencing and what they can do to prevent hearing damage, because hearing damage is permanent

 Hearing damage is caused by the combination of how long you listen (time), how loud you listen (volume), and what you listen to (energy content). The combination of these three factors create a “sound dose”, if the dose is too high it starts to damage your hearing.

 The UN’s World Health Organisation and hearing conservation organisations are increasing awareness of the risks and advise users to restrict their daily sound dose to less than 85dB average over 8 hours.

 Gamers who use headphones currently have no realistic way to indicate what level they are listening at and how much of their daily sound dose they have used. The answer will be to provide them with an intelligent sound dose measurement app or software, giving them their individual sound dose exposure information and guidance, with optional protection, so that for the first time they can make informed decisions about their hearing health.

Ham radio: A last resort when phone lines fail

We at this blog believe in radio communications and will never let it die, understanding the importance that it still plays, and during the worst catastrophes, will be the best form of communication. This story about 9-11 adds proof to this statement.

If disaster strikes, there is a form of communication that can still get through: a ham radio.

When 9/11 hit New York City in 2001, for instance, ham radio operators provided a connection to the outside world.

One of those people was amateur radio enthusiast Bob Kyvig, formerly of White Bear Lake, who now lives in Centerville.

“The only communication out there on 9/11 was amateur radio,” Kyvig recalled. “The telephone lines were jammed and no one was going in or out.”

On the days following that horrific attack, Kyvig assumed the role of messenger, relaying messages from Manhattan to loved ones in the area by calling or knocking on their door. His house calls would go like this: “I am Bob; I am a ham operator. I just communicated with your loved one; they are fine and doing well and they will talk to you soon.”

When White Bear Lake sailor Gerry Spiess landed in Samoa on his historic solo voyage across the Pacific Ocean in 1981, he contacted Kyvig, who connected Spiess with his wife Sally.



When Hugo’s tornado struck in 2008, he and wife Jill remained on the radio as long as they could but had to abandon the “ham shack” as the storm approached. The tornado did $30,000 damage to their home, including Kyvig’s outside antennas.

A ham since 1968, long before Facetime, email or Skype, Kyvig was 20 when he took up the hobby while serving in the Navy. He was stationed in Hawaii and had childhood buddies serving in Germany and aboard the USS Milwaukee. The three met on the radio at least once a week without fail for more than 40 years, until the death of one of the men in 2015.

That connection to people is what Kyvig most enjoys. He chats on the radio to people he’s never met around the world.

“It’s a worldwide network of people enjoying fellowship with other hams,” Kyvig said.

The radio operator answers calls for help in areas of “health and welfare,” and was on Centerville’s first CERT (citizen emergency response team), which is now inactive. He serves as a severe weather spotter too, and gains “insights” as to what is happening around the world by chatting to foreigners.

“We talk about everything from fishing, to weather and local problems,” he said. “It’s very interesting because you find out so much about people across the world. And it’s not just the personal part but handling messages for help in disasters.”

He’s listened to astronauts aboard the space station and scientists at the South Pole. He has talked to people in Russia, New Zealand and most of Europe. For a long time, he kept a conversation going with a man in Norway who lived close to some of his relatives. Wife Jill also has her ham license and enjoys talking to other women, known as YLs or young ladies, across the world. “Lord knows what they’re talking about,” Bob said. “I leave the room.”

Ham buffs do have opportunity to meet at events called “eyeball picnics.” The Kyvigs traveled to a picnic in Branson, Missouri earlier this summer to socialize with other hams and match voices with faces.

Without getting too technical, Kyvig explained that radio signals are bounced up through the ionosphere. The signal goes up and down several times before it hits the final destination and you don’t control where it hits. People who want to contact Kyvig can tune into his call number: WA0ROH, assigned by the Federal Communications Commission (FCC), which regulates interstate and international communications. The agency requires operators to keep a log of who they talk to on an electronic spreadsheet.

“We could be talking to people the FCC thinks is a bad guy,” he said. “Because we can transmit all over the world without a phone line, some use it to their own means.”

Other countries have comparable agencies.

Each country has its own beginning call letters. The United States uses W, K and N.

“The concept is simple,” he added. “We use what Mother Nature has provided: airwaves. We plug a number in for a country and anyone can answer.”

A true party line, Kyvig said 30,000 people could be listening in on a conversation.

Jill proudly pointed out that Bob earned a master’s degree from The 3905 Century Club. It’s not the typical academic degree, but a difficult achievement nonetheless. “The degree was a challenge,” he said, which explains why only 68 radio operators have received the degree since 1967.

Bob inspired her to get her license, Jill said, and together they do public service events using ham radio.

Invented in the early ’20s, ham equipment is evolving, but affordable. Newbies can do it for about $300, he said. There are antennas on his roof, but mostly they are horizontal wires stretched between a tree and the house. Generator backup is used if there’s a power outage. He also keeps a mobile 12 volt transmitter that he can use in his truck to chat while he’s driving.

At one time, working knowledge of Morse code was a requirement to get an FCC ham license, but that was dropped, so more people are getting into it, he said.

When he’s not on the radio, Kyvig enjoys making furniture and fixing TVs. He retired from a career in computer operations about five years ago.

Ham radio: A last resort when phone lines fail

We at this blog believe in radio communications and will never let it die, understanding the importance that it still plays, and during the worst catastrophes, will be the best form of communication. This story about 9-11 adds proof to this statement.

If disaster strikes, there is a form of communication that can still get through: a ham radio.

When 9/11 hit New York City in 2001, for instance, ham radio operators provided a connection to the outside world.

One of those people was amateur radio enthusiast Bob Kyvig, formerly of White Bear Lake, who now lives in Centerville.

“The only communication out there on 9/11 was amateur radio,” Kyvig recalled. “The telephone lines were jammed and no one was going in or out.”

On the days following that horrific attack, Kyvig assumed the role of messenger, relaying messages from Manhattan to loved ones in the area by calling or knocking on their door. His house calls would go like this: “I am Bob; I am a ham operator. I just communicated with your loved one; they are fine and doing well and they will talk to you soon.”

When White Bear Lake sailor Gerry Spiess landed in Samoa on his historic solo voyage across the Pacific Ocean in 1981, he contacted Kyvig, who connected Spiess with his wife Sally.

When Hugo’s tornado struck in 2008, he and wife Jill remained on the radio as long as they could but had to abandon the “ham shack” as the storm approached. The tornado did $30,000 damage to their home, including Kyvig’s outside antennas.

A ham since 1968, long before Facetime, email or Skype, Kyvig was 20 when he took up the hobby while serving in the Navy. He was stationed in Hawaii and had childhood buddies serving in Germany and aboard the USS Milwaukee. The three met on the radio at least once a week without fail for more than 40 years, until the death of one of the men in 2015.

Sony Announces AI Assistant Earpiece to Go on Sale in November - See more at: http://aibusiness.org/sony-announces-ai-assistant-earpiece-to-go-on-sale-in-november/#sthash.nm99apky.dpuf

Smart earpieces are the next frontier for the smart generation, we have all seen the earpiece that can translate instantly But that is just the start, as we can see from this article about this Xperia Ear wireless earpiece, it updates you from your phone when you put it in your ear. It won’t be long before we won’t need a smart phone everything will be in our ear.

Sony has revealed its ‘smart personal assistant’ that include a bluetooth earpiece will go on sale in November.

At the IFA show in Berlin today, the firm confirmed it will launch this November ‘starting in select markets,’ although its price has still not been revealed.

The Xperia Ear wireless earpiece can update you with any missed calls or messages as soon as you slot it into your ear.

The firm also showed off a Xperia Agent, a robot measuring just over one foot tall, that also works as a PA.

‘It will navigate you to where you want to go and make your life eye-free and hands-free,’ said Sony Mobile’s President and boss, Hiroki Totoki of the ‘her’ earpiece when it was unveiled at the MWC show earlier in the year.

‘It is also powered by Sony’s voice technology and will respond to a number of commands.’

The firm says the smart earpiece ‘is a next-generation wireless ear-piece that brings a new way of communicating, without compromising on enjoying the world around you.’

It reads users information such as your schedule, weather and the latest news to keep you up-to-date on the go.

Powered by Sony’s voice technology, it responds to verbal commands, so you can ask it to make a call, perform an internet search, dictate a message or navigate to a certain location.

It connects to an Android smartphone via NFC or Bluetooth and talks to a host application, where you can customise settings, including the info you need when you first connect in the morning, touch commands and app notifications.

‘Its lightweight and comfortable soft silicone ear-bud is built for continuous wear, with IPX2 water-protection and all-day battery life3,’ Sony said.

It’s available in Graphite Black and the innovative case doubles as a charger, so you can simply pop it in when you need to recharge.

It also unveiled the Xperia Eye, a wearable camera that acts as your personal sidekick, capturing everyday life moments with a 360 degree wide-angle lens.

Unveiled at Mobile World Congress (MWC) in Barcelona, the Xperia Eye can be attached to clothing or worn around the neck.

It forms part of a suite of connected gadgets designed to free people up from their phones.

Sony said the Xperia Eye is ‘a vision for a personalised assistant’ and joins three other smart gadgets that are connected to a Sony smartphone that acts as a hub, feeding information to them such as notifications.

These are Xperia Agent, Xperia Project and Xperia Ear.

Xperia Agent is a security camera-style device which acts as a home monitoring system, keeping an eye on what’s going on around it and projecting notifications fed to it from a Sony smartphone onto surfaces around it.

‘It will provide you with useful information, communication assistance and home appliance controls,’ Sony said.

Xperia Project projects an interactive interface onto any clear surface, meaning you can manipulate images, webpages and screens you would usually find on your smartphone, onto a hard surface.

Sony claims this projected image will respond to touch, voice and gestures just as someone would interact with your smartphone screen.

The Xperia Ear is a wireless earpiece that will update you with any missed calls or messages as soon as you slot it into your ear.

‘It will navigate you to where you want to go and make your life eye-free and hands-free,’ said Sony Mobile’s President and boss, Hiroki Totoki.

‘It is also powered by Sony’s voice technology and will respond to a number of commands.’

The wearable camera is the first time Sony has shrunk its image sensing and camera technology into such a small device.

Exactly what is the Best 2 way Radio For a Long Range

When choosing the best 2 way radio, it is important to note that doesn't matter which brand you pick. Whether you pick kenwood, Motorola, Icom, Hytera or any other brand, you should know that they all feature the same technology. Well, you might have noticed that most consumer radios tend to advertise a range that's up to 30 miles. Truth is, the consumer FRS/GMRS radios don't even provide anything close to the advertised maximum range; the range that a two way radio advertises is normally the range that a radio can get in the ideal condition. The ideal condition is clear line of sight like from the mountain top to the valley below; without any interference or obstructions.

Two way radios generally operate within VHF (that is Very High Frequency; 130 to 174MHzz) and UHF (that is, Ultra High Frequency; 420 - 470 MHz)) wave bands. Unlike the frequencies that are below 2MHz, the waves in these particularly higher frequencies travel in a straight line (also known as line of sight signal), and generally can't travel beyond your horizon. This basically means that distance to your horizon, is the actual maximum range for your 2 way radio; that is without the use of any additional equipment to boost the signals.

VHF waves (about 5 feet wide), are generally longer than the UHF waves, and they're most commonly used for long range/distance communication. If VHF waves and UHF waves were both transmitted in ideal conditions without any barriers, the VHF waves would travel nearly twice as far; as a general rule, the lower the wave frequency, the greater the distances it can travel.

Key to transmitting the radio waves for a long distance along the VHF waves is keeping the receiver and the transmitting radio above all possible obstructions or interfering objects. The VHF frequencies (because of the length of their waves), cannot transmit through some objects like walls, dense forests and hills. Typically, the transmissions which are sent along VHF waves are received and also sent high above earth's surface. VHF two way radios normally work better when there is a clear line of sight between the receiver and the sender. VHF two way radios are commonly used in marine and aviation communications where signals get sent across the open water bodies or between the ground and the sky. Television and FM radios also use the VHF frequencies where the signals are sent and also received high at the top of towers which are spaced all over the towns, cities and counties. VHF band walkie talkies are also perfect for landscaping, open fields, golf courses and also for outdoors security situations where there is less obstruction.

Though VHF can travel much farther, it doesn’t mean it is the better option. Reason is because of the differences between how the VHF and the UHF signals tend to react around buildings or structures. As you will find out below, UHF signals are shorter than VHF, and this is very important when you're in or around buildings.

UHF doesn't travel as far as the VHF, but has higher bandwidth occupation. One major advantage of UHF over the VHF, is that the antenna can actually be much smaller when its' used on the higher frequencies. Sometimes, a base antenna might be needed for radios using VHF frequency, but a small antenna on a radio can be comfortably used for the UHF frequency. Moreover, there are a lot more frequencies which are available when using UHF; this can be very useful in the areas which have a high population density.

The UHF radio waves are much shorter than the VHF radio waves (measuring at about one and half feet); the short length of UHF radio waves typically decreases distances at which the signals can get transmitted. This means that the line of sight between the receiver and the sender is much shorter in length with UHF waves. That being so, you should know that transmission of the UHF waves is usually high enough such that it can penetrate through the building walls and the urban outdoor settings. This is the reason why UHF 2 way radios usually work best for those who intend to use them in and around buildings and urban areas. A UHF walkie talkie with adequate power and a good sized antenna can reach further into the building, and push through steel, wood, concrete and earth. If you intend to use your 2 way radios exclusively indoors, or maybe indoors and at times outdoors, the the UHF is definitely the best choice. To explain this, let us use an example; assume you're trying to communicate with someone on the other side of the building and in between there's a metal wall which has a 3 foot opening. Basically, radio waves can't pass through metal. However, the UHF wavelength which is about 1 1/2 ft wide, will easily pass through the opening. In contrast, the VHF signal will bounce back since it's wider than the opening. This shows you that UHF is much better when it comes to navigating through smaller spaces within buildings to reach its' destination.

When it comes to power, many people tend to think that the power output increases the range, but actually the difference in the range between, say a 25W fixed VHF, and a 5W handheld, is because the fixed mounts the antenna being taller, thus can see farther. When you are trying to increase the range, increasing the height of your antenna is far more effective than increasing the power. Increased power will generally let you push through the static and such other radio traffic much better, but only within a range that's dictated by the height of the antenna.



In regards to obstacles, there are a lot of things which affect the signal strength of the radio waves. Therefore, it's important to consider the environment you intend to use your two way radios , and the actual range you need. Naturally, a football stadium will have much less obstructions as compared to a dense forest.

In conclusion, I would like to say that it is never about the radio you purchase, but the frequency, antenna and environment it will be used in. If your 2 way radio is going to be used mainly outdoors, where you will have a clear line of sight, then the VHF is the ideal choice, however, if the two way radio is going to be used in and around buildings, in urban areas, or in heavily wooded places, then the UHF is the best option.

Could hearing loss be a hidden cost of gaming?

Is this is a real problem? Do you use a set of headphones whilst gaming? This article has information on how damaging wearing gaming headphones is and what the future impact might be. Read this, examine how you use your headphones and get on with life…



According to the Q1 2016 GameTrack report, 18.8 million people between the ages of 6 and 64 game and those between 11 and 64 spend an average 8.8 hours per week doing so.

 Amongst Gamers the largest group is 15 to 24 year old males who are most at risk of permanently damaging their hearing. This group spends the most amount of time gaming and are also the most attracted to the “loud” games. Furthermore a majority of them live in a shared accommodation and use headphones so as not to disturb others. This group also the most likely to take part in other activities which can be harmful to their hearing such as listening to music through headphones, going to gigs and festivals, and nightclubs.

 Unfortunately the price of their enjoyment could well be significant and permanent hearing damage. Whilst there is clearly a risk to the Gamer, it could transfer as a liability to the games companies in the form of legal action relating to their duty of care.

 The first significant step is to make Gamers aware of how much sound exposure they are experiencing and what they can do to prevent hearing damage, because hearing damage is permanent

 Hearing damage is caused by the combination of how long you listen (time), how loud you listen (volume), and what you listen to (energy content). The combination of these three factors create a “sound dose”, if the dose is too high it starts to damage your hearing.

 The UN’s World Health Organisation and hearing conservation organisations are increasing awareness of the risks and advise users to restrict their daily sound dose to less than 85dB average over 8 hours.

 Gamers who use headphones currently have no realistic way to indicate what level they are listening at and how much of their daily sound dose they have used. The answer will be to provide them with an intelligent sound dose measurement app or software, giving them their individual sound dose exposure information and guidance, with optional protection, so that for the first time they can make informed decisions about their hearing health.

Those New Tracks You’re Listening to Are About to Sound Much Better

SO you’re walking down the street and suddenly the music kicks in, you drop to the ground and pull your earphones out of your ears! “what just happened” you think, then you realise the un-pause on the mp3 has just kicked in and you forgot to turn it down. Well people this will be a problem of the past with these earphones, Now all I need them to do is make coffee. VERY IMPORTAN You can find the original article here

What’s been your favorite set this weekend? Or the best new track you’ve shared with all of your friends? Well take that track and imagine listening to it in exactly the way your ears want you to.

Meet the Even earphones, who tune themselves to each person’s particular hearing. At just under $100, they customize the sounds they play to suit your own audio needs. They use their own EarPrint technology that measures how you hear different frequencies, then sets the earphones to play back sound specifically for each ear. As a result, the headphones give you a profile tuned to your own ear (each ear with its own profile).

One of the biggest things that originally drew me to the earphones was the fact that they are not a pre-order campaign â€" they have physical earbuds available now. The company, who launched in in June, has sold out batches twice thus far and are continuing to take orders on their website. Luckily, I was able to get my hands on a pair to try out as well.

I’m pretty picky about the gadgets I use for audio, as I’m constantly listening to music â€" digging for new sets on Soundcloud, reviewing new tracks, jamming out in my own world. Being able to plug in and listen to my own music is what allows me to focus and, as a result, I’m very specific about the type of earphones or headphones I use. That being said, I was overly ecstatic when I was handed a pair of Even earphones to try out.

First, their appearance: the cords are a high-quality string that have a smooth look and feel. The buds look sleek, with a simple black-and-white color scheme â€" one black, one white, with the EarPrint device hanging at the middle of the cord, meant to dangle at your chest. They don’t tangle easily, which makes them easier to carry without having to worry about dealing with knots. They’re the type of earphones I wouldn’t mind wearing out in public.

Next: the sound test. This is where we meet “Sarah,” the soothing female voice that guides you through a number of sounds to test where your hearing level is at. This test was very straightforward â€" Sarah literally starts by saying “Hi, this is really easy” â€" and felt very conversational as she talked you through each noise. Five pieces of music are played for each ear, and you’re required to hit the button once you hear the sound. Though the process takes a little bit longer than I’d like, it’s seamless.

Overall quality of the listening experience was great. I switched between my Bose over-ear headphones and the Even earphones to test the difference in sound quality and worked to try a few subgenres of electronic music to see how each would sound between both pairs. I started off by listening to Louis The Child’s set from Lollapalooza this year and instantly found that the vocals were much more emphasized than in my Bose headphones. Next, I moved on to Mikey Lion’s live set from Desert Hearts 2016 and loved the emphasis on the bass I was hearing â€" the Even earphones made it much more of an all-around experience. I then switched over to Troyboi’s tracks Do You? and O.G. to continue to test this bass theory and, again, Even delivered.

As my hearing is likely damaged based on the amount of festivals and shows I’ve attended over my lifetime, it was much appreciated that the earphones were able to pick up on the frequencies I have more trouble hearing to create the full experience tracks deserve. Interestingly enough, every time I switched back to my Bose headphones to compare, I had to turn the volume down because it came at full blast and was overwhelming â€" and, when I did, the clarity between vocals and bass was lost. All in all, these babies pack a punch with their sound quality when it comes to electronic music.

It’s refreshing that these earphones don’t require using an app, since that seems so commonplace nowadays. All of the information that goes into your profile is saved in the little box hanging onto the string, so you can plug them into any device â€" phone, laptop, iPod, whatever you want â€" and still have your own profile saved. I found this extremely helpful, as it meant that I don’t have to re-adjust my volume based on what device I’m using. Beyond that, it’s a refreshing change from listening to sets with friends and having to change the volume based on everyone’s sensitivities. It makes listening much simpler and, quite frankly, electronic music better. How could you say no to a custom-made, surround-sound system in your own ears?

To get you started, here a few sets, old and new, you may enjoy listening to in the earphones (ok, to be fair, these are sets that I would want to hear in them):

A review of the Icom IC-7300 direct RF sampling transceiver

Icom and ham radio go hand-in-hand, one of their main markets is supplying top of the range equipment, this IC-7300 follows on from the wonderful IC-F7200 (which is a favourite in the office) and sits along side the new range of digital IC-F1000 & 2000 radios that are going really well, but have a new connector type, so new Icom radio earpieces are needed. Read the comprehensive review we found from the swling.com website.

In August 2015 at the Tokyo Hamfair, Icom debuted a new type of transceiver in their product lineâ€"â€"one featuring a direct RF sampling receiver. Essentially, it was an SDRtabletop transceiver.

At about the same time that the IC-7300 started shipping around the world, Icom pulled their venerable IC-7200 off the market. Yet the IC-7200 was established as a well-loved product, due to its highly sensitive receiver, its relatively robust front end, and its quality audio. Moreover, it was simple to operate, which made superb as a Field Day or radio club rig.

Therefore, even though the IC-7300 promised much more versatility than the IC-7200, for its price point it had a tough act to follow.

So, of courseâ€"â€"even more so than with any other radio Icom has introduced in the past few yearsâ€"â€"I was eager to get my hands on a IC-7300.  I’m very fortunate that my good friend, Dave Anderson (K4SV) was one of the first purchasers of the IC-7300, and that he didn’t mind (after only having the rig perhaps one week!) allowing me to borrow it for a several weeks for evaluation.

Note:  I should state here that since this rig was loaned to me, I evaluated it based on the firmware version it shipped with, and made no modifications to it.

Icom-IC-7300-FrontThis review primarily focuses on the receiver’s performance, functionality and usability.

Introducing the Icom IC-7300

In recent years, the “big three” ham radio manufacturers have been using color displays, andâ€"â€"Icom most especiallyâ€"â€"touch screens. While I’m no fan of backlit touch screens in mobile applications, I  think touch screen displays make a lot of sense in a base radio. If carefully designed, a touch screen can save an operator from heavily-buried menus and decrease the number of multi-function buttons on the front panel.

The challenge, of course, is making a display with intuitive controls, and one that is large enough, and with sufficient resolution, to be useful to the operator. In the past, I’ve been disappointed by many displays; the most successful have been incorporated in DX/Contest-class (i.e., pricier) transceivers, meanwhile, entry-level and mid-priced transceiver displays often seem half-baked. While the graphics may be crisp, spectrum displays at this price point are often too compressed to be useful, and if not a touch display, force the user to pause operation in order to find the correct knob or button to change settings. In such cases, I find myself wondering why the manufacturer went to the expense of a color display at allâ€"â€"?

Icom-IC-7300-Display

But what about the C-7300 display?  I’m thoroughly pleased to report that Icom did afantasticjob of balancing utility and function in design of the IC-7300’s color touch display and front panel. There are  number of ways you can chose to display and arrange elements on the screenâ€"since I’m an SDR fan, I typically chose a display setting which gave the waterfall the most real estate. Of course, one can chose to give the frequency display priority or a number of other arrangements.

User interface

I can tell that Icom built upon their experience with the IC-7100â€"â€"their first entry-level touch screen display transceiver.

I was able to get the IC-7300 on the air in very little time. Within five minutes of turning on the IC-7300, I was able to:



  • change the display to feature a spectrum waterfall;


  • change the span of the waterfall display;


  • adjust the TX power output;


  • change the filters selection and the transmit mode;


  • change bands and make direct-frequency entries;


  • adjust notch, passband, and filter width;


  • adjust AF and RF gain;


  • set A/B VFOs and operate split;


  • change AGC settings;


  • turn on Noise Reduction/Noise Blanker, and


  • adjust compression.




Basically, I found that all the essential functions are clearly laid out, accessible, and highly functional.  Impressive.

The IC-7300 ships with a manualâ€"â€" aptly titled, the “Basic” manualâ€"â€"and a CD with the full and unabridged operations manual.  The Basic Manual covers a great deal a lot more than the manual which accompanied the Icom ID-51a. If you read through the manual, you’ll readily familiarize yourself with most of the IC-7300’s higher function operations, and especially, you’ll be able to adjust the settings to your operation style. The Manual is written in simple language, and includes a lot of diagrams and graphics.

If you’re like me, you will find you’ll also need to reference that unabridged manual, so hang on to the CD, too.

Still, I imagine there’s a large percentage of future IC-7300 owners that will never need to reference the manualâ€"â€"especially if they don’t care about tweaking band edges or similar settings. Yes, believe it or not, it’s that easy to use.

Operation

Icom-IC-7300-Function-Buttons

While I spent a great deal of time listening to CW and SSB in various band conditions and at various times of day, I spent less time on the air transmitting.

With that said, all of my transmitting time was in CW since the IC-7300 mic was accidentally left out when my friend loaned me the rig.

I’m please to report that CW operation is quite pleasant. All of the adjustmentsâ€"â€"RF Power, Key Speed, and CW Pitchâ€"â€"can be quickly modified using the multi-function knob. While in CW mode, you can also toggle full break-in mode, which is quite smooth, via the function button and touch screen.

SSB functions are similar. While in  SSB mode, the multi-function knob allows you to change the tx power, mic gain, and monitor level. The function button opens an on-screen menu with VOX, compression, TBW, and the monitor toggle.

Here’s a short video I made with my phone while I made a few adjustments to the IC-7300:



Of course, my smartphones’s microphone can’t accurately reproduce the audio from the IC-7300, but you probably get the idea.

The only annoyance I notedâ€"â€"and perhaps I’m more sensitive to this, being primarily a QRPerâ€"â€"is that the 7300’s cooling fan starts up each time you key up. It even comes on when transmit power is at its lowest setting. I find this a little distracting in CW.  Fortunately, however, the 7300’s fan is fairly quiet and operates smoothly.

Receiver performance and reader survey results



Since our radio comparison shoot-outs have been particularly popular (and useful; check out our shoot-out between top portables, and ultra-compact radios, and others), I decided it would make sense to invite our informed readership to evaluate the Icom IC-7300’s performance in a series of blind, informal tests. (For information about these surveys,please read the first survey.)

Below, I’ve matched the labels (Radio A/Radio B) with the radio models.  I’ve also included pie charts which show the results from the survey.

Icom IC-7300 vs. WinRadio Excalibur



Weak Signal CW (40 meter band)



CW

Based on listener comments, those of you who preferred the ‘7300 did so because the CW was more interpretable and stable.

Some of you noted that I didn’t quite have CW at the same pitch on both rigs. I believe this is because the IC-7300’s calibration was ever so slightly off. This has since been addressed.

Weak/Strong SSB QSO (40 meter band)

SSB

This result was almost tied. The Excalibur’s audioâ€"â€"without any adjustmentsâ€"â€"has a fuller and “bassier” sound. The ‘7300 can be adjusted to have similar characteristics, but the default EQ settings produce very flat audio. Many of you commented that the IC-7300 more faithfully produced audio optimized for SSB.




 

Shortwave Broadcast recordings



The following recordings were made on the 31 meter broadcast band in the evening. Both radios had the same filter width: 9 kHz and 8.2 kHz.

Weak Shortwave AM (Radio Bandeirantes 31 meter band)

Weak-SW-AM

There was a noticeable preference for the WinRadio Excalibur in this particular audio set. Even though the Excalibur’s audio splattered a bit, the content was more interpretable. The IC-7300’s audio sounded flat in comparisonâ€"â€"again, something that can be adjusted quite easily in the ‘7300’s audio settings.

Strong Shortwave AM (Radio Romania International, French 31 Meter Band)



Strong-SW-AM

Once again, the Excalibur won favor, but I imagine results would have been closer had I adjusted the ‘7300’s audio EQ.




 

Mediumwave Broadcast recordings



Note that the following mediumwave recordings were made during the morning hours (grayline). The strong station is the closest AM broadcaster to my home; it’s not a blow-torch “Class A” type station, merely the closest local broadcaster.

In the “weak” sample, I tuned to 630 kHz where multiple broadcasters could be heard on frequency, but one was dominant.

Both radios are set to a filter width of 9.0 kHz.

Strong Mediumwave AM (1010 kHz)

Strong-MW-AM

Two out of three listeners preferred the Excalibur in this example.

Weak Mediumwave AM (630 kHz)

Weak-MW-AM

In this particular example, the IC-7300 could not pull the strongest broadcaster out of the pile as well as the WinRadio Excalibur. In fairness, the Excalibur was using AM sync detection, something the IC-7300 lacks.

Icom IC-7300 vs. Elecraft KX3



IMG_20160424_105444629

I also decided to pit the IC-7300 against my well-loved Elecraft KX3.




Audio Clip 1: CW (20 meter band)

Elecraft KX3: Radio A

Elecraft - CW

Based on comments, readers who preferred the IC-7300 felt the CW sounded more pleasant and stable.




Audio Clip 2: Weak Signal CW (20 meter band)

Elecraft - WeakCW

Your comments indicated that the CW seemed to “pop out” of the noise slightly better with the IC-7300.




Audio Clip 3: Weak/Strong SSB

(Sable Island working Asia/Pacific on 20 meter band)




Elecraft SSB

These results were spilt in the middle. Again, I believe this comes down to personal preference in the audio. And againâ€"â€"in both radiosâ€"â€"the audio EQ can be adjusted to suit the operator.




Receiver performance summary

I enjoy producing audio clips for readers to compare and comment upon. Each time I’ve done so in the past, I’ve had listeners argue the virtues of a particular audio clip while others have the complete opposite reaction to that same clip. Not all of us prefer our audio served up in the same way. No doubt, there’s a great deal of subjectivity in this sort of test.

I’ve had the IC-7300 on the air every day since I took possession of it. I’ve listened to SSB, CW, and lots of AM/SW broadcasters.

And here’s my summary: the IC-7300 is an excellent receiver. It has a low noise floor, superb sensitivity and excellent selectivity. I even slightly prefer its audio to that of my Elecraft KX3, and I’m a huge fan of the little KX3.

I’ve written before about how difficult it is to compare SDRs; the problem is that there are so many ways to tweak your audio, filters, AGC, noise reduction, etc. that it’s hard to compare apples with apples.

In the audio samples above, the IC-7300 and WinRadio Excalibur were both set to their default audio settings. In SSB and CW, the IC-7300 excels, in my opinion. CW seems to pop out of the noise better and SSB is more pleasant and interpretable. The Excalibur has a better audio profile for AM broadcasters, though. Its default audio simply sounds fullerâ€"more robust.

The audio from the IC-7300 on AM sounded absolutely flat. However, if I tweak the audio of the ‘7300, adding more bass, it instantly sounds more like a dedicated tabletop receiver.

I should also mention that while the IC-7300’s built-in digital recording is a fantastic and effective feature, it doesn’t produce audio true to what’s heard through headphones live. This is especially the case when you add more bass and treble response as in the RRI example above. When the audio EQ is set to a default flat, it’s quite accurate.

To be clear:  for broadcast listening, I’ll still reach for my SDRs (the Excalibur, FDM-S2,TitanSDRand CR-1a).

If, however, I have limited space and/or budget for multiple receivers, I’d be quite happy using the IC-7300 as a broadcast receiver on the HF bands.

Speaking from the Shortwave Radio Listener (SWL) perspective, meanwhile, am I pleased with how the ‘7300 handles the broadcast bands?  Most definitely.

And as a ham radio operator, am I pleased with the IC-7300’s receiverâ€"â€"?  Absolutely.

In short:  the IC-7300 seems to have some of the best all-around receiver qualities of any transceiver I know under $2,000.

Summary



Every radio has its pros and cons. When I begin a review of a radio, I take notes of my initial impressions. Here’s my list for the IC-7300:

Pros



  • Excellent sensitivity and selectivity


  • Excellent, highly-customizable RX and TX audio


  • Color touch screen interface


  • Spectrum display is large enough to be useful


  • Intuitive functions


  • Twin PBT is both intuitive to operate and effective


  • Effective RF gain to compensate for noisy band conditions


  • Built-in RX and TX recording, file transfers via common SD card


  • Front panel knobs and buttons are spaced appropriately and easy to use


  • Quiet cooling fan (see con)


  • Decodes RTTY on screen


  • Built-in ATU


  • Antenna analyzer function (not tested)




Cons



  • Lacks secondary receive antenna jack on rear panel


  • Cooling fan immediately starts up on CW/SSB transmit at any power setting (see pro regarding fan noise)


  • Occasionally you may get lost in deeper customized functions


  • Supplied printed basic owner’s manual, while well-written, doesn’t fully cover the IC-7300s functions and options; you must explore the digital owner’s manual in supplied CD.




Conclusion

In a nutshell: Icom has hit a home run with the IC-7300.  If I didn’t already have an Elecraft KX3 and K2, I would buy the IC-7300 without hesitation.

Though the price point is a little high for an “entry level transceiver,” it’s worth every penny, in my opinion. For $1500 US, you get a fantastic general-coverage transceiver with an intuitive interface, nearly every function you can imagine, and performance that would please even a seasoned DXer.

Though I haven’t done and A/B comparison with the IC-7200, I imagine the IC-7300 would prevail in a test. The IC-7300 would certainly wipe the floor with it’s more economical brother, the IC-718.

Radio clubs, take note:

In my view, the IC-7300 has the makings of an excellent radio club rig in which performance, functionality, as well as ease of use are important. I expect that the IC-7300 will not only cope very well with crowded and crazy Field Day conditions, but it will also give any newcomers to the hobby a little experience with a proper modern transceiver. The fact that you can view signals so easily on the spectrum display means that it will be easier to chase contacts and monitor bands as they open and close. Indeed, what better way to mentor a newly-minted ham in modes, contacts, carriers, QRN, QRM, and so forth, than to simply point these out on the IC-7300’s bright, clear displayâ€"â€"?

If your club is considering a transceiver upgrade or purchase, do seriously consider the IC-7300. I think you’ll find this rig is up to the task.

And for home? The Icom IC-7300 may be all of the rig you’ll ever need.
