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 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€"?


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.



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)


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)


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)


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)


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)


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

Weak Mediumwave AM (630 kHz)


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


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.


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:


  • 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)


  • 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.


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.

Imtradex Aurelis Handheld Microphones Future Proof to fit all Purposes

We call these Remote Speaker Mics (RSM) and they have come in all different shapes and sizes over the years. Normally a staple of the emergency services, but we have seen a upsurge in general radio users using RSM’s. So it comes as no shock to us that a pro-active company like Imtradex has designed one to suit the needs of the masses.

What was originally developed as a handheld microphone for digital radios, has blossomed over the past few years to an essential equipment accessory for digital radio standards of emergency service: The Aurelis hand microphone from Imtradex.

Meanwhile with the Aurelis, the specialist for critical communications, have a whole series of hand microphones on the market, all adapted to the specific challenges of the communication in critical applications of security agencies, fire departments, dispatch and emergency services. The Aurelis series addresses the different needs of the user: based of the basic model Aurelis Base, Imtradex manufacture customized versions that are specially tailored to the range of functions that meet the customer’s requirements.

All the Aurelis hand microphones have a send button, a microphone and high quality speakers. “All devices contain a cable attachment and also the possibility to connect external audio accessories” adds Ralf Kudernak, CEO of Imtradex. Depending on the radio, different data applications can be integrated, so can ex. on the model Aurelis AudioDis, information be displayed on the LCD display.

“The youngest member of the family is the Aurelis USB handheld microphone, which is designed for connection to computer-based communication system, especially for control centers” informed Ralf Kudernak. “The USB interface gives the easy integration and can be connected independently to each operation system and used with existing hardware. With the development of the Aurelis USB, we followed the desire of several control centers, which wanted to use a handheld microphone which you can also hang at the table of the workplace” said Kudernak.

In terms of digital communication, security and flexibility the innovative ultra-lightweight Aurelis Nexus PTT set new standards. It was specially designed for fire fighting. Thanks to it extra large PTT, with short sensing path and exactly defined pressure point, the operation with use of working gloves is possible.

The user can also be flexible in their choice of radio and headset: All Aurelis handheld microphones can be combined, not only with many headsets, for example with the monaural neckband headset from the NB Series. They are convenient and safe to wear, provide a maximum safe mobility and provide an excellent voice quality. Imtradex can also build them with the different connectors required, so they can easily be connected to different digital radios. All Aurelis handheld microphones have a robust plastic housing. Is splash-proofed and protects the device against dust and against temperature influences, so they can be reliably used in a temperature range from -30 to + 70 degrees Celsius. The 180 gram lightweight Aurelis handheld microphones are also available in different colours and optionally equipped with a car holder or cloth clip.

In Ear Monitor Buyer’s Guide: Custom vs. Generic Fit

It is understood that ear moulded plugs are far more comfortable and effective than the mushroom plugs, but which ones are the best? The Custom fit or generic fit. This article runs over the positives and negatives of that question and comes to a conclusion, if your debating to get some moulded ear plugs or some from the shelf, you will want to read this first.

Over the past 20 years, In Ear Monitors (or IEMs) have become a near-necessity for live performance.

In years prior, engineers would inevitably have to crank up a venue’s stage monitors loud enough for the musicians to hear themselves over the audience, over the sound coming from the stage, and over the main mix.

This would often lead to an arms race of ever-increasing stage volume, potentially causing feedback issues and compromises in clarity and quality for the live mix.

Custom in-ear monitors from JH Audio, one of the first commercial brands to make a name for itself in the IEM market.

With the advent of in-ear monitors, all this began to change. In the mid-1980s, Etymotic developed the first-ever insert-style earphones, and soon after, a designer named Marty Garcia began making one-off custom in-ears for rock stars like Todd Rundgren.

By 1995, Jerry Harvey, founder of Ultimate Earsand JH Audio, brought some of the first commercially-available dual-driver IEMs to market. All of a sudden, everyday musicians had an option that allowed us to save our hearing, get better monitor mixes, and dramatically reduce the chances of feedback onstage.

Today, IEMs are increasingly being considered useful tools for the studio as well. Their ability to prevent sound leakage can be of tremendous value in helping to control click and instrument bleed, and in saving musicians’ hearing by allowing them to monitor at lower levels.

Some musicians and engineers, such as drummer Rich Pagano of The Fab Faux, will use IEMs to quickly check for phase when mic’ing up a drum kit, while others turn to IEMs as a kind of audio microscope, using them to help check for and remove extraneous low-level noise.

Any modern musician would be wise to consider adding in-ear monitors to their toolkit. But is it worth it to dish out the extra money on custom fit IEMs, instead of saving some money with the generic fit ones?

In testing a variety of in-ear monitors from brands like Westone, Ultimate Ears, Future Sonics, and even Skullcandy (that last of which is not recommended for professional use), I have found that there are cases in which generic fit earphones may work better than their custom counterparts. Making the right decision for your needs comes down to considering the following four factors:

1) Cost

Ultimate Ears custom fit in-ear monitors.

Custom fit IEMs tend to cost more than generic fit ones, as it takes more time and effort for the manufacturer to craft a product designed specifically for the unique anatomy of your ear.

Getting custom IEMs made also requires that you go to an audiologist to make a mold of your ear canal that the IEM company can then use to make your monitors fit as well as possible.

Take note of both of these costs, which can range from $100-$200 or more for a fitting from an audiologist, and $299-$1499 or more for the custom monitors to be made.

2) Comfort & Seal

Custom fit IEMs are custom, so they should feel really comfortable, right?  Well, yes and no.

In my experience, custom fit IEMs can feel a little tight in the ear canal compared to generics, especially at first. Hearing so little acoustic feedback from your performance can also take some getting used to, and the tight seal of custom fit in-ears can feel particularly awkward when signing.

Because of this, my looser-fitting Westone 3 generic IEMs actually feel more comfortable to me on vocal duties, so I often find myself using them over my custom fit Future Sonics when I step up to the mic.

Matt Bellamy from Muse (recently featured in Get THAT Guitar Tone) has been seen using both customUltimate Ears UE-11s and generic-fit Westone UM2s when on tour, and my guess is that he has similar reasons.

Though the tight fit of custom IEMs and lack of acoustic feedback from your performance can be a challenge, it’s worth noting that generic foam-tip IEMs also provide their own tradeoffs: The looser fit of generics can sometimes create a bit of a tingling or “tickling” feeling in your ear when playing at higher volumes, so it may be useful to have a pair of each and go with what feels best depending on the date and venue.

Silicone-based Encore Studio custom IEMs from ACS.

Another option here is the custom fit brandACS, which makes its IEMs out of soft silicone shells.

This softer silicone-based design is meant to offer both better comfort and a tighter fit than the hard acrylic shells used by brands like Westone and Ultimate Ears.

Though these silicone monitors sell for a premium price of $400-$1,200 and up, they may help bridge the gap between the tight seal of custom acrylics and the looser and easier fit of foam-tipped generic IEMs.

3) Hearing Protection

In addition to cutting down on sound leakage to help improve sound quality and reduce feedback, another primary benefit of IEMs is that they can offer considerable hearing protection by helping to block out exterior noise, allowing you to monitor at lower levels.

Some of the best custom fit brands like JH Audio and Ultimate Ears offer NRR ratings of 26dB in reduction, and some of the better generic brands advertise comparable results as well. (Though your results with generics may vary depending on the fit and seal in your ear.)

In the long term, reducing the levels you’re regularly exposed toâ€"even by a few extra decibelsâ€"could mean the difference between a long and illustrious career as a “golden-eared” audio engineer and potentialtinnitus and irreversible hearing loss.

Also worth checking out is the REV33 system, which can be added on to your your in-ear-monitoring system to help reduce distortion and ear strain. Many live musicians, including Phil X and Steve Salas swear by the system. According to the company:

“All in-ear monitors and headphones generate damaging, unwanted noise and distortion that forces the ear to shut down and compress for protection. The REV33 reduces the symptoms of tinnitus, ear-ringing, ear-fatigue, buzzing and dampened hearing by preventing in-ear monitors and headphones from producing this unwanted noise and distortion.”

4) Waiting and Time Considerations

After getting my first pair of IEM’s made, I found that the right ear monitor turned out well, but I was not getting a proper seal in the left ear at first. This made the monitors essentially useless for my live sound needs at the time, and so I had to send them back for some tweaking.

When I got them back a couple of weeks later, the seal still wasn’t great, so I had to send them back once again for further modification, and visit my audiologist a second time to take another impression of my ear canal to send in.

Getting the perfect fit turned out to be quite a time-consuming process (as well as an expensive one) so unless you’re on the hunt for a long-term solution with as much acoustic isolation as humanly possible, you might satisfice with generic IEMs, or keep some around as an alternate option.

In that case, I would recommend the generic in-ears from Ultimate Ears, Shure, or Westone.

Ultimate Ears’ generic fit UE900 model sports 4 drivers for $400.

The Ultimate Ears UE900’s are a great sounding 4-driver IEM that only costs $399, while the $99 Shure SE215 single-driver IEMs advertise an astonishing 37dB of noise reduction (more than most custom IEMs) at a great price.

My own triple-driver Westone 3’s (since replaced by the W30 model) are the most comfortable in ear monitors I own right now, and they isolate a lot more noise than most thanks to their foam-tip construction.

Compared to custom in-ears, any of these model can potentially save you time and money, or work as a welcome supplement for those times when the tight fit of custom in-ears feels irksome.

I hope my experiences here help you make the right decision when you go to buy your own IEMs. In short, I found that less-expensive generic foam-tipped IEMs worked better for me in many situations, and the savings enabled me to spend my money on better drivers with a fuller sound.

If you’ve used IEM’s in the past, let us know in the comments below whether you prefer custom fits or generic fit ones, and why.

Why Are Good Communication Skills Important?

Take a second and look at Human beings, really look at us. We’re not as strong as elephants or rhinos, we’re not as tough as lions or tigers and we can neither swim like fish nor fly like birds. Yet, despite all this, there is still one inescapable fact: Human beings are the dominant species on the planet.

The short answer to your question lies implicitly within the above paragraph. With good communication skills, a group of disparate individuals can overcome a great many obstacles by working together. It is believed that our earliest ancestors were able to ward off predators by sticking together in large groups and thus presenting a formidable target (as opposed to, say, a buffet). We were also able to hunt prey much larger and stronger than ourselves (e.g. the woolly mammoth) by co-ordinating our efforts with good communication skills.

Such good communication skills are, not to put too fine a point on it, vitally important to the Human race as a whole. This excerpt from ‘Mutual Aid: A Factor of Evolution’ by Russian author Peter Kropotkin (1902), illustrates what we’re trying to say better than we ever could.

“Man is the result of both his inherited instincts and his education. Among the miners and the seamen, their common occupations and their every-day contact with one another create a feeling of solidarity, while the surrounding dangers maintain courage and pluck”

In other words, their shared lifestyle is a form of communication, the result of learned social primers and a lifetime of experience. It is the secret ingredient to our success as a species.

Good communication skills in the workplace operate along the same basic principles as they do outside the workplace. The goal is clarity, but equally, the speaker wishes to illustrate her point of view and encourage others to sympathize with it. This is why politicians pay their speechwriters as handsomely as they do.

Communication skills are also Vital to Human interaction. Humans are able to learn all sorts of things by listening for verbal cues that we are unconsciously primed to respond to. Information about a speaker’s age, class, race, gender and even occupation can be gleaned from the simple act of listening to a person. To quote Peter Trudgill’s book ‘Sociolinguistics: An Introduction to Language and Society’ (1974),

“Different social groups use different linguistic varieties, and as experienced members of a speech community we have learnt to classify speakers accordingly”, for those interested - this is known as ‘social-class dialects’.

You might ask how this affects you. Well, consider this; if you are applying for a typically upper or middle class job (say, office manager as an example) and you speak with a traditionally working-class accent, vocabulary and demeanour during your interview, you are actually less likely to get the job than the applicant who uses received pronunciation and does not use colloquialisms or slang terms. You might be more qualified on paper, but the interviewer will likely say something about you not being “the right fit” for the position. This is because he has been primed to expect a certain type for a certain role. Therefore, good communications skills, in this instance at least, would hinge on your ability to appeal to listeners by meeting their expectations.

Of course, we now know that such distinctions are unfair. Combating expectations of class, race, gender and sexual stereotyping led to the rise of ‘political correctness’, a much-maligned (and often justly so) and yet consistently misunderstood phenomenon.

For a more extreme example, imagine giving an obscenity-laced PowerPoint presentation at your next meeting. Once you stop laughing, consider the implications even if everything in the presentation was 100% accurate, (groundbreaking, even) you’d still be fired, wouldn’t you? Swearing is, of course, a lower-class way of communicating.

You need to find the correct words for the correct situation, but evidently, there has been a great deal of discussion as to what are the correct words.

If you want to know more, the poem ‘The Six O’Clock News’ (1976) by Scottish poet Tom Leonard is a good place to start. In the UK, we study it as part of GCSE English (or at least we did when this writer was at school), and the poem neatly highlights the social and class-based distinctions that typified (and still do to some extent) ‘normal’ speech and any important announcements..

So, in conclusion, communication skills are important because without them, nobody would be able to understand YOU.

The Sepura Group to Provide Communications for the Olympic Games

It’s a brave move by the olympic organisers, the London Olympic communications was run by Riedel and they did an excellent job, they have experience in this field, but the Brazilians are obviously set on using Teltronic and we all hope that they do just as good as a job.

Teltronic, part of the Sepura Group, has been chosen by the public security secretary of Río de Janeiro State in Brazil to supply communications for the Summer Olympics and Paralympics, informally known as Rio 2016.

The €10m contract will cover four venues (Barra da Tijuca, Copacabana, Deodoro and Maracanã), two airports (Rio de Janeiro/Galeão - Antônio Carlos Jobim International and Santos Dumont) and several key transport routes in the Olympic area.

The agreement with Teltronic will see an extension to the traffic capabilities of the existing Teltronic network currently used by the Rio police, as well as the installation of further Nebula base stations to provide additional coverage for the state police and emergency services, and the Olympics organisation workforce.

The existing network was originally provided by Teltronic for the Pan American Games in 2007 and, after some upgrades, is now supporting over 100 dispatch operators and more than 18,000 radios. This new upgrade for the Olympics will feature two extra TETRA carriers for each site, to update the capacity of the existing network; base stations with up to 12 TETRA transceivers to support high traffic loads throughout the event; a CeCoCo Control Centre, to accommodate a further 50 dispatch operators; an additional 6,000 terminals featuring Teltronic's Synchronous Data Manager application to pare down the GPS refresh time in AVL applications; and 24/7 maintenance and operational support during the Games.

"This win builds on our long-term relationship with the Brazilian authorities and public safety agencies," said Paulo Ferrao, the Sepura Group's sales director for Brazil.

"We have a strong background in events of this scale, having supported communications for the FIFA World Cup 2014 and the Pan-American Games, both huge events in the sporting calendar of Brazil and, indeed, the world. We are delighted that Rio de Janeiro's public safety agencies have, once again, placed their trust in us."

Superintendent of critical communications at the Security Secretariat of the State, Colonel Alexandre Corval, commented: "We are extremely happy to have chosen Teltronic.

"The company has been a trustworthy partner to our public safety agencies for over ten years. Once again, they have exceeded our expectations in terms of technical development, quality of the deployment and, above all, their dedication to customer service: throughout the project, they have paid close attention to our technical and operational requirements.

"We are confident that this extension to the existing Teltronic TETRA system will optimise our mission-critical communications, enhancing the security of both visitors and employees throughout Rio 2016."

Innovative radio solution protects and preserves Chinese forests

We all know how important radio communications are, and Motorola Solutions have captured a massive coup by providing the radios for protecting the Chinese forests, a feather in the cap for Motorola because Hytera, their biggest competitor at the moment, originating from china, interesting! We found this article on this website.

Motorola Solutions (NYSE:MSI) with its channel partner Beijing Dyne Rcomm Technology are helping to keep China’s Hunan forestry region safe with a MOTOTRBO digital radio system that increases safety and security for employees while helping them to work more efficiently.

China’s Hunan province is rich in flora and fauna resources that are essential to the region’s economy. However, these vast areas which make up around 60 percent of the province’s total surface area can be risky places to work for forest rangers. Forest workers depend on reliable communications to be aware of potential bushfire risks and other emergencies.

The innovative radio system integrates MOTOTRBO digital two-way radios and repeaters, a dispatch console for centralised control and monitoring of the network at all times and Motorola Solutions’ IP Site Connect digital solution to extend radio network coverage over the internet throughout the counties and cities.

“Rangers depend on access to clear and reliable communications. They need to stay constantly connected to their colleagues working in control rooms who have visibility of the entire operation and can help to keep them safe at all times,” said Michael Jiang, China President and Country Manager, Motorola Solutions.

“It’s absolutely essential for forest rangers to know where their co-workers and resources are at all times, especially in times of emergency.

“Hunan’s new radio network provides extensive coverage throughout the region, enabling rangers working across a wide geographic area to report the very first signs of fire so that resources can be deployed quickly and effectively to protect lives and natural resources,” Mr Jiang said.

Hunan’s integrated system connects the surrounding cities and counties through clear voice communications enhanced with noise cancelling features that perform reliably in the nosiest environments. This system also supports data transfer across the radio network, using GPS to pinpoint the location of nearby team members and resources in emergency situations, while text messages and automatic alerts can be sent between the province’s central control room and radio users in the field.

Motorola Solutions has now deployed more than 5,000 radios to major forestry projects across greater China at locations including the Inner Mongolia, Hebei, Liaoning, Sichuan and Guangdong provinces.
