The Minerva Tropic Master: a portable WWII era morale radio

If you’re a regular here on the SWLing Post, you’ve no doubt discovered that I’m a fan of vintage radios.

Lately, I’ve been attempting to let go of some of my vintage gear to give my favorite rigs proper shelf space and dedicated antenna time. To keep temptation at bay when I visit flea markets or hamfests (like Hamvention and the one in Shelby, NC) I now focus on WWII era radios; specifically “morale” radios that were used for troop entertainment. I’ve two morale sets: the Scott Marine Radio Model SLRM (technically, a commercial version of a Navy set) and the Minerva Tropic Master.

I purchased this Minerva set off of eBay a couple years ago. I got it for $50 or $60, if memory serves (the seller originally wanted $180 + shipping!). He claimed it worked, but after I asked him a few questions prior to making an offer and learned that “working” meant the speaker prodeced a noise and the backlight worked. I made a low offer and he accepted.

Last year, I took Minerva over to my buddy, mentor and boat anchor doctor, Charlie (W4MEC). Charlie discovered the radio had many issues and several poorly implemented repairs. Still, in a few short weeks, when parts arrived he brought the girl back to life.

The Tropic Master is a portable eight tube receiver that covers both the AM broadcast band and shortwave bands from 5.5-18 MHz. It can be powered by AC or DC. It was “tropicalized” to withstand extreme heat and humidity. The internal speaker produces mellow, full-fidelity audio and the volume can be increased to room-filling.

To give you a taste, this morning I tuned the Tropic Master to my in-house AM transmitter on 1570 kHz which was being fed audio from The UK 1940s Radio Station (my favorite Internet radio station). This particular clip features Jay Lawrence’s excellent show, From Stateside:

The Tropic Master is portable and even has a fold down handle on top of the chassis. Though substantial, it must be the lightest of all of my vintage metal chassis radios.

Tuning isn’t exactly precise, but it does the job and is a pleasure to use. It’s quite sensitive on both shortwave and mediumwave. Last night, she was tuned to the Voice of Greece on 9420 kHz–I probably listened to two hours of Greek music while her eight tubes warmed the shack.

Who could turn down a radio with this speaker grill?

If you ever find a Minerva Tropic Master at a flea market or hamfest, I say adopt one! It’s a beautiful receiver and like all good vintage radios has a story and history of its own.

Post readers: Any other Tropic Master owners out there or do you have a morale radio? Have you ever spotted a Tropic Master in the wild? Please comment!

Andy remembers his first issue of the WRTH

Many thanks to SWLing Post contributor, Andy Howlett, who writes:

Always nice to see another WRTH arrive, even though I haven’t actually bought one for many years. Attached is a pic of the very first one I bought, back in 1980.

I only got it as it contained a review of the then spanking-new Trio R-1000 HF receiver, which I was thinking of splurging my meagre wages on.

On the basis of that review, I went ahead with the purchase and discovered it was a cracking RX and I only sold it on in the early 90’s to enable the purchase of an ICOM R-7000, another cracker!

Merry Christmas to you and all listeners everywhere.

Thank you for sharing your memories with us, Andy, and Merry Christmas to you!

Now an annual Christmas tradition, Brian Justin (WA1ZMS) will put his longwave experimental station WI2XLQ on the air to commemorate the 110th anniversary of Reginald Fessenden’s first audio transmission.

WI2XLQ will be on the air from 17:00 UTC Dec 24th on 486 kHz and run for 48 hours until 16:59 UTC on Dec 26th.

Listener reports may be sent to Brian Justin, WA1ZMS, at his QRZ.com address.

If you would like more information about Brian Justin and WI2XLQ, check out our interview with him in 2013. Indeed, I successfully heard the 2013 WG2XFG broadcast and posted this audio clip on the Shortwave Radio Audio Archive.

Additionally, SWLing Post reader, George Stein has a very personal connection with radio pioneer, Reginald Fessenden: click here to read his story.

BBC Genome Project releases 1930s editions of Radio Times

(Source BBC Genome Blog)

The BBC Genome Project is releasing the next batch of pages from Radio Times, this time covering the 1930s.

Genome users will now be able to access the articles, editorial material, letters pages, illustrations and photographs from the 1930s. We hope this will help users correct some of the errors in the Genome data – as well as gain insights into broadcasting during this fascinating period.

The 1930s was a turbulent decade. The country had to cope with the worldwide depression and mass unemployment that followed the Wall Street Crash of 1929. In 1936, King George V died, but his successor Edward VIII abdicated at the end of the year, to be replaced by George VI, his younger brother. Internationally, the decade was marked by the rise of the Nazis in Germany, and the sequence of events which culminated in the outbreak of war in September 1939.

It was a period of change in broadcasting too. At the start of the 1930s the BBC was still overseen by Sir John Reith, its first Director General. In 1932, the BBC moved from its cramped headquarters at Savoy Hill to the purpose-built Broadcasting House.[…]

From the Post Archives: Radio Free Whatever–A Pearl Harbor Tribute

President Franklin Roosevelt called December 7, 1941, “a date which will live in infamy”–the day Japan attacked Pearl Harbor, Hawaii by air.

This morning, I was reminded of an off-air recording I made in 2013 of the pirate radio station, Radio Free Whatever. Please enjoy this bit of history from the Post archive:

USS Shaw exploding in Pearl Harbor on December 7, 1941

For your listening pleasure: one hour, seven minutes of the pirate radio station, Radio Free Whatever.

I recorded this broadcast on December 15 2013, starting around 2:40 UTC, on 6,925 kHz AM. This broadcast was a tribute to WWII and Pearl Harbor and contains news clips and music from the same time period. I believe my recording begins about five or so minutes into their broadcast.

From the Shortwave Archives: Radio RSA reviews the Sony ICF-2001

I’ve mentioned many times before what a joy it is to curate the Shortwave Radio Audio Archive (SRAA). Sometimes I’m sent recordings that evoke a flood of memories. SRAA contributor, Tom Laskowski, just submitted another such recording.

Tom included the following notes with his Radio RSA – Voice of South Africa recording:

Every Saturday night during the early 1980s [in South Bend, Indiana] I would regularly tune to 9580 kHz at 0200 to listen to Radio RSA (Channel Africa as it is now known) to hear DX Corner, their regular DX program.

This episode from March 14, 1982 was a look at a brand new hot radio, the Sony ICF-2001.

The audio isn’t great but should be listenable. I think this was recorded using my new Realistic DX-302. Enjoy:

 Thank you, Tom! I think Radio RSA did an admirable job reviewing the ICF-2001!

Post Readers: You can listen to more archived shortwave recordings at the SRAA website, or by subscribing to the audio feed via iTunes. You can also listen to the archive on TuneIn radio.

Space Flight: Colin’s collection of Radio Moscow recordings on the Shortwave Radio Audio Archive

One of the joys of running the Shortwave Radio Audio Archive (SRAA) is that, over time, more and more people have become aware of it and submit recordings they’ve had in their private collections for decades.

Quite often, SRAA off-air recordings were originally made on reel-to-reel or cassette tapes which degrade with time. When SRAA contributors take the time to digitize these recordings, and share them via the SRAA, they put these collections in the hands of hundreds of archivists. We’re grateful each time we receive one of these shortwave or mediumwave/AM recordings.

You can imagine my excitement when I received the following message from one of our newest contributors, Colin Anderton:

“As a space flight nut, I have many recordings from the 1970s from Radio Moscow. They used to broadcast on the medium wave, and I used to record the news bulletins during some of the space flights. In particular, there was a period between December 1977 and March 1978 when Soviet cosmonauts first lived aboard the Salyut 6 space station.  I recorded each days’ news reports on the flights, and also some additional items about them.”

Colin’s recordings are amazing. Here’s a sample from December 10, 1977:

We’ve started publishing Colin’s recordings on the archive at regular intervals.

Interestingly, I discovered that Colin also has a website dedicated to NASA highlight recordings from the space age.  Several months ago, he spent a considerable amount of time making the public domain series more listenable–removing voice-actuated recorder noises, tape clicks, etc.

Colin has made his collection of re-engineered NASA recordings free to download on his website. If you download and enjoy his recordings, consider dropping him a donation. If you’re into spaceflight like I am, you’ll certainly enjoy this collection:

Colin, once again, thanks so much for adding your off-air recordings to the Shortwave Radio Audio Archive!

Indeed, thanks to the many contributors who make the archive such a treasure trove of broadcast recordings! Click here to browse the Shortwave Radio Audio Archive.
