The Elite Satellit: Can Eton Deliver to Radio Users Who Expect Higher QC and Feature Standards?

by Dan Robinson

It’s been many years since the original E1 took the hobby world by storm. Everyone remembers the issues that plagued the E1, from the rubber coating that degraded over time, to display and encoder issues, and the calibration issues that frustrate some users.

In anticipation of the arrival of the Elite Satellit, I got both of my E1s out of storage — one in the 9xxx serial number range required a de-gooing session, accomplished quite well using Max Pro cleaner and 70% alcohol. It was interesting note, during that process, that the XM module on one side of the radio was more sensitive to color loss than other parts of the cabinet, reducing to an almost silver color when all was finished.

Original Eton E1 XM

Using the original E1s provided a reminder of how good these receivers were and still are, if you have managed to avoid display and encoder issues. The combination of PBT, triple selectivity and highly-effective SYNC was a blockbuster combination. The radio failed only in the area of quality control.

As Universal Radio and other distributors prepare to send out the first tranche of receivers, some thoughts are in order. The first is that one hopes Eton has lessons from the first go around regarding Quality Control. I have a sinking feeling about this based on my experiences in recent years reviewing receivers by Tecsun.

Eton needs to know that those who will buy the Elite Satellit, and that includes old-timers like myself but newcomers to the hobby, now have much higher standards specifically because of the features we have seen Tecsun and some other manufacturers put in portables.

Primarily, the presence of a recalibration capability really poses a challenge where the Elite Satellit is concerned. Discerning buyers no longer have to put up with a radio that has calibration and/or stability problems. This is why I am curious as to whether Eton included an adjustment function through software or an adjustment hole as with the original E1. So far, there has been no confirmation on this question from Eton or anyone else.

Original Eton E1 XM

With an older E1, tweaking of the master oscillator was possible through the small adjustment hold in the rear of the radio cabinet. This was tricky since in many units the hole was inconveniently located directly under one of the plastic ribs on the back.

I solved this problem by gently cutting a small section of one rib with a Dremel or similar tool, providing easier access. Still, adjustment has to be done carefully due to the sensitivity of the pot, and preferably with a non-metallic jewelers flat head screw driver. Even then, movements of the radio would often throw the radio back off.

But again, E1 users were spoiled by the recalibration capability which Tecsun included on receivers from the PL-880 to the 990x and 501s and even the PL-368, all of which provide a software method of zeroing frequency in SSB. Even Malahit SDRs have a fine adjustment setting in software.

If Eton has not taken this into account, and has not made any recalibration possible, I fear that it may face a good number of buyers who will simply return radios that suffer from significant frequency error. In short, a “good enough for government” approach by Eton when it comes to calibration QC is simply not going to be sufficient because for years now, Tecsun has been setting a higher standard.

Physical cosmetic issues too will also be an important indicator as to Eton’s attention to QC. If Eton learned its lesson from the rubberized cabinet fiasco, this should not be a major problem. But I would urge owners of the new Elite Satellit to examine your radio for QC issues, like LCD pixel problems, wobbly knobs and loose encoders, and issues with the telescopic antenna.

All of this becomes even more important because Eton is charging so much for this radio. Even taking inflation into account since the original E1 appeared, $599 for a radio that adds only HD and AIR band as features, but which still might suffer from QC problems is extremely high and I fear Eton may end up with numerous returns if the Elite Satellit fails in any key areas.

So, the clock ticks down to the moment when many of us will receive that box containing the Eton Elite Satellit. The question is will what is inside be able to meet the higher standards we have come to expect from a multi-band portable?

Giuseppe’s latest homemade ferrite antenna for MW and SW

2 Replies

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who writes:

Dear friends,

I’m Giuseppe Morlè from Formia, central Italy on the Tyrrhenian Sea.

I want to share with you my latest ferrite antenna for listening; it is composed of 3 ferrites of 20 cm each in a tube for electrical systems with 2 separate windings, one for medium waves and one for short waves, 40 turns for medium waves, 4 turns for short waves. I use a 750 pf variable to tune the 2 windings and a switch is used to eliminate a winding.  Since there is only one variable, if you listen to the medium waves I interrupt the winding of the shorts.

On shortwaves it is preferable to place the system on an iron railing which, due to inductive effect, behaves like a really long wire antenna.

For the mediumwaves it is enough to bring the receiver close to the ferrites and also in this case, the induction will have its effect with an excellent increase in signal and modulation.

The range of this portable antenna is:

      • 520 to 1800 kHz
      • 3.500 to 18.000 MHz

Here’s a video from my Youtube channel where I explain how it works:

I had previously built a similar antenna but with 12 cm ferrites–very portable.

Thank you for your attention and I wish you good listening.

73. Giuseppe Morlè iz0gzw.

This is brilliant, Giuseppe! I love how you never stop building and experimenting with various antenna designs! Thank you for sharing this with us!

Many thanks to SWLing Post contributor, Pedro Andrade, who shares the following article. Note that the following excerpt has been translated by Google from Italian to English. Click here for the original in Italian at FM-World.it:

On 11 September 2022 Rai radio broadcasts in medium wave will cease (FM World)

Before the end of the summer, Rai will end radio broadcasts in medium wave .

[…]The news, already anticipated in recent months by sector magazines such as Italradio , is made known by the Easy Web section of Rai .

Everything comes from the audio description for the blind, available for some programs in the second audio track of the TV channel concerned, but also in medium wave on Rai Radio1 .

With regard to this latter service, the site (accessible by clicking HERE) specifies that “from 11 September 2022, due to the termination of Rai radio broadcasts in medium wave modulation, the audio descriptions of television programs for the blind will be available only on dedicated audio of digital terrestrial television.

The regular Rai radio programs , therefore, will continue in FM , DAB + , web and app .

Thanks for the tip, Pedro.

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Triple J is shedding young listeners, but radio isn’t a dead medium yet (The Age)

I’ll never forget the excitement I felt as I bought my first transistor radio with a hard-saved pile of silver coins. I was 9, and I wasn’t just getting a piece of shiny kit, I was gaining access to a whole world of music and chat and cool that might somehow magically bind me to the other kids in my neighbourhood and at my school.

That thrill was only topped when, in my teens, I discovered the seditious sounds of student radio on the FM band, and realised there really were other people like me in the world. Like Jenny in the Velvet Underground song, I turned on a radio station and my life was saved by rock and roll.

It’s doubtful, though, that young listeners feel the same way about the medium today. While they consume vast quantities of music, much of it is via streaming platforms like Spotify, YouTube and TikTok. The radio isn’t the principal conduit to a world and identity – it’s just one channel among many. And when they do listen to radio, young people are increasingly shunning the stations targeting them in favour of golden oldies.

The latest Australian radio survey results saw Smooth FM pick up considerable market share in the younger demographics – 10-17, 18-24 and 25-39 – and much of it came at the expense of the ABC’s youth-focused network Triple J.

In the survey, which covered the period of February 27 to May 21, Triple J clocked an average audience of just 78,000 listeners in the five mainland capital cities across the full listening week (from a total of 1.56 million average radio listeners). In Sydney, it held a 3.9 per cent share of the listening audience, in Melbourne 4.5 per cent. It did better in Brisbane, where it has a 6.7 per cent share of listening, Perth (6.8 per cent) and Adelaide (5.1 per cent). [Continue reading at The Age…]

Audio – it’s Radio, but not as we know it. (Radio Today)

Comment from Dean Buchanan.

Much is made of Radio’s digital future in Australia. The publicly listed broadcasters and the industry body CRA are obsessed with digital. And so they should be as the content equation continues to fragment and the battle for your attention increases. The buzzword is AUDIO.

However, this appears to me at the significant risk of over-looking the goose that lays the golden eggs – FM and AM radio. The audience numbers and revenue this “traditional” medium continues to generate are staggering and dwarf many “digital audio” businesses.

This from radiotoday.com.au: “Commercial radio ad revenue in May was up 11.2% compared to May 2021, continuing months of sustained growth in the sector. (April was up 8.8%) That’s according to data released today by industry body Commercial Radio Australia. Ad revenue for the five major Australian capital city markets totalled $66.273 million during the month compared to $59.605 million a year ago. Commercial Radio is currently flying on all fronts with record audience listening levels in the most recent GFK survey and now an 11.2% year on year increase in commercial revenue for May.”

I would have thought that’s something for Radio to be very proud of, especially in the light of declining television viewership and publishing readership trends? But the word Radio is in danger of extinction.

This from SCA’s Annual report: “The four pillars of our refreshed corporate strategy are to entertain, inform and inspire our audiences; to establish LiSTNR as Australia’s ultimate audio destination; to use our assets to help our clients succeed; and drive and embed a digital audio first operating model.” Where’s Radio?

Don’t Overlook the Benefits of OTA (Radio World)

The author is a retired broadcast engineer who has been involved with advancing radio and television throughout his career, including for Qualcomm/MediaFLO, Harris, Nautel and ONEMedia LLC/Sinclair.

There are days when I feel like Ira Wilner, who wrote a piece here in reply to my commentary about NextGen TV.

Why bother with OTA broadcast? That is the question, isn’t it? But then, several explanations come to mind.

OTA is free. It’s hard to beat free. Streaming delivery requires an ISP or wireless data payment. Subscription satellite is needed when one drives through nowhere. Admittedly, many of us have connectivity in all the places we want it for other reasons; thus, sometimes it is a “sunk cost” for listeners, but always an additional, buy-it-by-the-bit, per-listener CDN cost for broadcasters.

OTA is low-friction. It’s hard to be smoother than navigating on-off/volume/tune.

OTA doesn’t buffer. It does not (and should not on NextGen) require searching with a browser. Done well, there isn’t even a “channel change” delay.

Try surfing through the dial on IP. Try scanning for local stations when travelling. I like local. On Sunday nights, I could stream “The Big Broadcast,” WAMU’s longest-running program, which I became addicted to when I commuted east; but I dial up KCFR or KUNC here in Denver instead. I am that lazy. I hate friction.

And if we don’t have an FCC license, just exactly what are we? Pause and contemplate what we’d be without a signal and those magic call letters. [Continue reading at Radio World…]

Groundbreaking children’s hospital radio station RX Radio appeals to public for support (IOL)

Cape Town – This Youth Month, award-winning RX Radio, run by and for children and based at the Red Cross War Memorial Children’s Hospital, are appealing to the public for help to keep the groundbreaking initiative going.

RX Radio celebrate their fifth birthday this year, with a studio based at Red Cross Hospital and their broadcast feed reaching the paediatric wards at Brooklyn Chest and Paarl Hospital.

With a vision of reaching every hospital with a paediatric ward in South Africa, RX Radio has trained over 135 young reporters from ages 4 and up.

A team of five staff, one intern, one mentor, volunteers and former reporters work behind the scenes to train, co-ordinate, and support the reporters – but the children are always behind the microphones and are active participants in the production; they design their own shows, choose the music, invite guests, write interviews, questions, and even plan fundraising events.

RX Radio founder, Dr Gabriel Urgoiti said: “Children make up 34% of people in South Africa; you see them everywhere, but at the same time you don’t see them, children are quite invisible. What RX radio continues trying to do is provide a platform where children can be heard and children can be engaged on things that are important to them. We provide them with an opportunity to talk, and working at hospitals has helped children with chronic conditions tell their stories and improve healthcare delivery.” [Continue reading at IOL…]

Radio Nostalgia: Bob’s first radio

Many thanks to SWLing Post contributor, Bob Colegrove, who shares the following guest post:

My Very First Radio

By Bob Colegrove

Sears and Roebuck Co., Silvertone, Catalog No. 8003, Model No. 132.818-1

I don’t remember much from 1949.  I was seven years old and still in the first grade.  I do remember being gifted a radio by my mom and dad on my birthday.  It was a Sears and Roebuck Co., Silvertone, Catalog No. 8003, Model No. 132.818-1.  I don’t really remember asking for it.  I’m sure mom and dad did not have a clue as to how consumed I would become with radio over my lifetime.  In truth, this was not the radio that got me totally absorbed, rather that function would be filled in 1958 by the Howard Radio Co. Model 308 combination MW/SW radio-phonograph console which had been relegated to the basement in favor of the TV set.

In 1949 television was on the cusp of success, and AM radio was still the one-way Internet of its time.  I recall my mother listening to countless soap operas during the afternoon.  The Howard was still in the living room and we listened to all the popular programs at night.  Anyway, the Silvertone was mine.  It took up residence in my room and I could independently explore the wonder of five local stations broadcasting in Indianapolis at that time.  There were no parental guidance settings on the Silvertone, nor was there any need.

The Silvertone was not a world-class radio with all the sensitivity, bells and whistles I would later desire.  Below WXLW, 950 kc it was deaf.  It was, in fact, one tube short of an “All American Five.”  However, one of its four tubes was dual function, if you counted the detector.  It was what was called an “ac-dc” radio.  This meant it could be powered by either 110 Vac or Vdc.  Granted, there were a couple communities in the US which were still serviced by dc power at this late date, but that fact certainly did not warrant advertising.  The whole thing always seemed to me no more than a marketing ploy on the part of manufacturers to cover for the lack of an expensive isolation transformer in the circuit.  Given the fact that electrical standards of the time did not provide for polarized outlets and power cords, these things could be quite hot, and it’s amazing so many tinkers, myself included, are around to talk about it.

One Tube Short of an “All American Five”  

The dial was very crude, and the tiny tuning knob swept all 107 available channels in a 180-degree twist of the variable condenser.  My mom, always handy with a paint brush, took to marking favorite stations  with a dab of nail polish.  1430 kc was WIRE and 1070 kc was WIBC.  Perhaps she got the idea from Bill Halligan who used little red dots on the controls to indicate the setting that would likely produce some noise.

The printed media were sizeable and substantive in the 1940s.  The Indianapolis Star’s morning edition for Friday, April 13, 1945 was particularly mournful as the U.S. woke up to the news that the president had died the day before.  I was later given to understand that many stations broke from the normal schedule for a few days to play somber music.  Notwithstanding, the first section still bore the quintessential hourly radio program schedule from 6 am to midnight for each of the four local stations.  We always kept clippings of station logs for each day of the week.

My interest in baseball grew over the next couple years, and the Silvertone played an important role in my keeping up with the local AAA team.  The static on a summer night was atrocious.  Further, in those days, the broadcasters were not compelled to fill the air with chatter between pitches.  There were no recitations of mindless statistics and no color commentators to describe the nuances of sliders and curve balls.  Consequently, between pitches there were often long pauses of nothing but dead air.  If you happened to tune in during a pause you had little idea where WISH, 1310 kc was on a hopelessly crude dial.

Most minor league broadcasters did not travel with the team.  When the team went on the road, they used an old Model 15 clickety-clack Teletype machine in the studio.  A local guy at the distant ballpark would observe a pitch or play, and quickly type a cryptic message on his Teletype.  On the radio you would first hear the receiving Teletype spring to life in the studio as the message came in.  The announcer would quickly interpret it, and then embellish the play with some excitement as best he could.

Teletype Model 15

During those times, it was not too uncommon for the Teletype to suddenly go down during the game.  What to do?  An announcer was suddenly left to his own creativity to fill in airtime.  Possible solutions were to describe the lengthy process of extricating a stray animal from the field, or a sudden cloudburst and consequential rain delay.  An intrepid announcer went on as nothing happened, making up the play-by-play over the interval.  Invariably, when the Teletype came back up, he found himself not quite in sync with the game and possibly a few runs behind.  At that point the challenge was to patch in the necessary play and go on to complete the game to the satisfaction of an otherwise unsuspecting audience.

Well, after 73 years, I’ve seen my share of radios.  In the meantime, the Internet has made it possible to DX the entire world at any time on a fifty-dollar Kindle – excellent fidelity, no interference, no noise, no fading.  But, after all these years, I still cherish those static-filled ballgames and teletype machines heard on the Silvertone a long time ago.

Quietly Waiting for the Next Pitch

Opinion: The Future of AM Radio
England, Scotland, Wales and Northern Ireland (FrequencyFinder.co.uk)

Summary

AM radio in the British Isles is now in terminal decline with audiences dropping and many transmitters closed already. The majority of the remaining transmitters will likely close by the end of 2027. Over the next few years, the BBC and major commercial broadcasters will be looking to minimise their AM transmission costs by reducing transmission powers at the high-power sites and closing some of the low-power transmitters serving small audiences.

A coordinated AM shutdown may then follow at some point, most likely in 2027, though some independent broadcasters may continue using AM beyond this. This article explores these issues in more detail.

ITU’s ham radio station celebrates 60 years on air (ITU)

By Nick Sinanis, callsign SV3SJ, President of the International Amateur Radio Club (IARC), and Attila Matas, callsign OM1AM, Vice-president and Station Manager, IARC

Did you know that the United Nations specialized agency for information and communication technologies owns and operates its very own radio station?

Residing at the headquarters of the International Telecommunications Union (ITU), the 60-year-old amateur station operates under the callsign 4U1ITU.

It started broadcasting on 10 June 1962 and was officially inaugurated the following month by then UN Secretary-General U Thant and ITU Secretary-General Gerald Gross – himself a ‘’ham” radio enthusiast known by the personal callsign W3GG.

Recognized as a unique “country” in the ham radio community, 4U1ITU operates in accordance with privileges extended by ITU and the Government of Switzerland. It has also earned the DXCC (or ham radio “century club”) award from the American Radio Relay League (ARRL), confirming air contacts with 100 or more countries.

From its long-time home on the 5th floor of the Varembé Building in Geneva’s international district, this unique broadcasting outlet still today serves as a model for the highest standards of amateur radio station operation everywhere.

From one to a million

4U1ITU’s first contact, or “QSO” in ham radio parlance, was made with a German station called DL4VK. Further QSOs followed, amounting to over 1,300 contacts worldwide in the first 24 hours.

In the six decades since, ITU’s radio station has made over a million contacts using Morse code carrier wave (CW), voice (SSB), and digital operational modes, based on more than 20,000 two-way QSOs with radio amateurs around the world.

4U1ITU can operate on most of the frequency bands allocated to amateur and amateur-satellite services as identified in Article 5 of the Radio Regulations.

Aside from letting licensed radio amateurs in ITU, its Member State representatives, and its conference and meeting delegates contact fellow radio hams, the station promotes international goodwill and cooperation across the community. It also allows hands-on demonstrations of amateur radio communications for delegates and meeting participants. [Continue reading…]
