GatesAir is suspending the sale of new AM transmitters.

When a prominent radio engineer passed along word to Radio World that he’d sought a quote from the manufacturer on a new transmitter but was told the company had discontinued the model and was assessing its AM line, we sought to learn more.

Chief Product Officer Rich Redmond replied: “Recent changes in the long-term availability of critical components from our suppliers, including several last-time buy notices, have caused us to take proactive steps to ensure we can meet our continued support obligation of our AM products,” he said.

“To safeguard our ability to offer an ample supply of spare components — and to secure the ongoing field support of our AM transmitters — GatesAir has taken the responsible step of suspending new AM transmitter sales, and will instead focus on supporting existing customers’ transmitters with our available components.”[…]

Tom praises Anon-Co’s “first-rate” customer service

Many thanks to SWLing Post contributor, Tom Adams (W9LBB), who left the following comment on our Tecsun PL-880 review:

Just a note re. kudos to Anon-co re. customer support.

I got a PL880 late last year, and LOVED it; so much so that I ordered a second one, the “special edition” version, both radios from Anon-co.

While waiting for the second radio to be delivered, my first one developed a bug; the AM broadcast band was dead at turn-on. Sometimes switching to FM and back to AM made it work… not good.

The second radio arrived, and it worked on short wave for about 5 minutes, and went dead. Turning it off and waiting a while brought it back… but it would die in 5 – 10 minutes again.

I wrote Anon-co about the problems, and Anna addressed the problems. After the usual fixes (reset, pulling the battery for a half hour and reinserting to reboot the processor) failed, she had me send both radios back for factory service. Anon-co covered the cost of the FedEx to get them back to Hong Kong.

A half hour ago I got a note from Anna.

The newest radio is confirmed dead; they’re replacing it.

The older radio (sent for repairs under warranty) seems to have developed a bug that the technicians have never seen before. They say that diagnosis and repair could be very difficult… therefore they are replacing THAT radio too!

I’m a happy camper with that solution… and I can’t praise Anon-co and Anna too highly! FIRST RATE customer service!!!

Thanks for sharing this feedback, Tom. I’ve had the same experience with Anon-Co over the many years I’ve done business with them. Anna is an amazing customer-focused agent and they stand by their products each and every time.

There are so few companies who retail shortwave radios these days it’s nice to know that Tecsun’s primary distributor in Hong Kong is one of the best in the business! We can buy from Anon-Co with confidence.

Radio Survivor: Exploring and Preserving the Brooklyn Pirate Radio Scene

Check out this brilliant episode of the Radio Survivor podcast which features our Shortwaveologist friend, David Goren along with John Anderson of Brooklyn College:

(Source: Radio Survivor)

There are more unlicensed pirate radio stations in New York City than licensed stations. The borough of Brooklyn is a particular hotspot. Producer and journalist David Goren has been researching and recording these stations so that their ephemeral nature isn’t lost to history. To help preserve this legacy and make it accessible to a wider audience he’s constructing an interactive map of Brooklyn pirates, due to be released later this year.

David joins us on this episode along with Prof. John Anderson of Brooklyn College, who has been tracking and researching unlicensed radio for two decades. We discuss the unique qualities of Brooklyn pirates, and how they fulfill the needs of communities that are underserved by other media, why it’s important to preserve their legacies, and why the expansion of low-power FM failed to provide sufficient opportunities in cities like New York.

Guest Post: Radios I Have Known #2

Radios I Have Known #2 The old, the new, and the Select-A-Tenna

by Neil Goldstein

L-R: Select-A-Tenna, Tivdio V-115, Sony ICF-5500W

After promising this series a year and a half ago, I finally have started digging through the collection, and will start posting about once a week.  The radios, and accessories may not have anything in common (as seen in this post), but were all acquired because they were in some way interesting, or sentimental to me.  Here’s the first three:

Select-A-Tenna
One of the original air-core tunable AM antennas.  You just put this near the radio and peak it for reception.  I was watching for one of these in good shape, and not overpriced, and they have been in and out of production over the years.  This one is from a later production run as can be seen by the extended AM range (1700).  Jay Allen reviewed the S.A.T by comparing the the TERK Air Core antenna not long ago here:  https://radiojayallen.com/select-a-tenna-vs-terk-am-advantage/  The TERK reviewed well, and looks more modern, but I wanted the classic cheesy art-deco looking S.A.T.

Tivdio V-115
I won’t post a long, boring review here.  Many have already reviewed this radio.  All I can say is that if you like small, decent-sounding transistor radios, you will not be disappointed.  If you are expecting top-shelf performance, and perfect ergonomics, then you you may not be happy, but for around $19 you really should be happy with this little gem.  A great little radio at a great price and the most impressive thing here is the sound.  The radio has a small passive radiator like the Meloson M8, and M7, and really surprises me.  It can also be used as an amplified speaker, and has a micro SD slot for using it as a standalone MP3 player.  Grab one!

Sony ICF-5500W
Most transistor radio collectors know this radio.  It’s a classic for sure, but I have to give a little background on why I wanted one.  When I was about 12 years old, I had a few analog SW portables, but nothing with direct frequency readout.  Panasonic had introduced it’s series of direct-readout radios, the RF-2200, 2800, and 4800, and Sony was competing with the ICF-5900W.  Dad acknowledged the quality and technology of these radios, and told me that if I saved most of the money by working for him, he may help me get one.  The 2800, and 4800 were way out of reach, but one Sunday in the local paper, a department store in Kingston (Britt’s, which was Newberry’s answer to Macy’s) had the 2200 advertised for $138.88.  I had been flip-flopping between the Sony and the Panasonic for weeks, but that was the clincher.

The radio is still in use.  My sister in law has it.  I had given it to my late brother Paul at some point and she still uses it as her main radio.

Why this Sony though?  I still want a 5900W.  When I saw this one come up at an auction, I recognized the shape it was in.  The ICF-5500W was the companion radio to the 5900W.  AM/FM and VHF Hi (with a basic, but functional squelch control).  The 5500 and 5900 are a monument to Sony design at the time.  The pop-up antenna (which still works flawlessly), The separate Bass, Treble, and Loudness controls, The overall quality of sound and function, all of this is an example of what Sony was producing at the time.  I think their modern small electronics are a shadow of what they were capable of years ago.  This thing still sounds great and performs well next to my modern DSP radios.  I still would love to get a pristine 5900W but they usually fetch premium dollars.  Maybe someday.

Bravo Sony, but where did you go?

More to come!!


Thanks for sharing, Neil!  I, too, have the Tivdio V-115 and the Sony ICF-5900W.

The ‘5900W is a gem of a solid state receiver. It has brilliant AM broadcast band reception and rich audio. I need to open my ‘5900W and clean all of the contacts since some of the sliders are scratchy. It’ll make for a nice rainy day project!

We look forward to your next installment! Post Readers: be sure to check out Neil’s blog, Fofio!

Radio spotted in “The Day the Earth Caught Fire”

Many thanks to SWLing Post contributor, Mark Hirst, who has discovered yet another radio in film:

Spotted this in the 1961 sci-fi movie, ‘The Day the Earth Caught Fire‘.

I’m guessing it’s an old military set.

I believe it is indeed, Mark!  Perhaps an intrepid SWLing Post reader can sort out the model number?  Please comment!

I’ll add this post to our growing archive of radios in film.

78 Megahertz: Australian astronomers detect signal from the dawn of the universe

Astronomers detect signal from the dawn of the universe, using simple antenna in WA outback

They have picked up a radio signature produced just 180 million years after the Big Bang using a simple antenna in the West Australian outback.

The ground breaking discovery, reported today in the journal Nature, sheds light on a period of time known as the “cosmic dawn”, when radiation from the first stars started to alter the primordial gas soup surrounding them.

[…]The signal they’ve been looking for is a miniscule fraction — between 0.1 and 0.01 per cent — of the radio noise from the sky.

“It’s like trying to hear a whisper from the other side of a roaring football stadium,” Professor Bowman said.

The signal is also within the lower range of FM radio, so finding a place on Earth that is free of human radio interference was essential.

That’s why Professor Bowman and colleagues decided to base their experiment at CSIRO’s Murchison Radio-astronomy Observatory, 300 kilometres north-east of Geraldton.

“Going to Western Australia and working at the Murchison Radio-astronomy Observatory was an absolutely critical first step for us,” he said.

There they built a small table-sized radio spectrometer with a radio receiver attached to two metal panels that act as an antenna. Akin to a set-up from the 60s or 70s, the EDGES instrument is much simpler in design than bigger array telescopes around the world.[…]
