Many thanks to SWLing Post contributor, Bob Colegrove, who recently shared this excellent article and has kindly allowed me to share it here in the the Post. Bob prefaced it by saying, “Being a retired technical writer, I started the attached article some time ago for my own amusement, but it quickly got out of hand.”
“Got out of hand” in a very good way, Bob!
An excerpt from Bob’s article.
I love how this piece takes us through receiver history and explains, in detail, the mechanics and innovations. It’s also a very accessible piece that both the beginner and seasoned radio enthusiast can appreciate.
But don’t take my word for it, download it and enjoy!
Thank you again, Bob. This is a most enjoyable and informative read! This was obviously a labor of love. Thanks for sharing it with our radio community!

Dear Thomas,
I noticed a New Zealand news article that may be of interest to SWLing Post readers.
Approximately 400 vintage radios are to be auctioned in Nelson, New Zealand. Whilst I use more modern Tecsun radios, the article will be of interest for vintage collectors. Many of the Radios are New Zealand made and rare.
Thank you, Jason. Even though this auction has been widely publicized in New Zealand, the collection is so massive, I imagine bidders will be walking away with some excellent bargains. If I lived in NZ, I would certainly be a part of the bidding. I’d love to have an NZ-made receiver.
I really like the following quote from the Stuff.co.nz article:
The widower of the man who stockpiled the radios told Walker her husband had collected the stash from all over the country.
“His wife was a wee bit disappointed she didn’t know he had half the radios because he used to keep hiding them.[“]
How many of us can relate to that last statement? Let’s face it: par for course, right!? 🙂

Stumbled on this rig at an estate sale and laid out a cool $5.00 for her. She was mostly in pieces in a big plastic bag covered in a LOT of dust, and the battery compartment had seen better days. But I thought I could get it going.
Once I got to the chassis I noticed someone with a Golden Screwdriver had been rooting around in there (the PS module was missing screws to the frame and there was some solder bits dancing around inside).
Threw in 4 C cells: pots were noisy, but there was sound, and after liberal application of De-Oxit and some scrubbing the thing snapped to life! Quite good MW reception: I snagged KMOX 1130 St. Louis at 06:30 GMT this morning, a good hop of 960 miles.
Hammarlund only made this Weather/Marine band receiver in 1969-70, so it’s a rare bird, though probably not collectable, per se. Still, it was fun to get the thing operational.
Oh wow! Thanks so much for sharing your flea market find with us, David! I’m so glad you were able to not only give this HR-10 a proper clean-up, but also bring her back to life–and even snag some DX!

What an impressive amount of vintage radios! I’m planning to attend Hamcation next year (2020)–now I know I’ll need to bring my truck to haul back all of the boat anchors! 🙂
Many thanks to SWLing Post contributor, Mike Thomas, who shares the following reply to our recently post highlighting a number of novelty radios. Mike writes:
That is a nice collection of novelty radios. I have a few of them but tend to focus on early production transistors.

Wow! What a remarkable collection, Mike! Thank you for sharing!
Last week, I picked up the first season DVDs for the TV science fiction series “V” at our local library. I somehow missed this series when it was first produced in 2009–however, I do remember clearly the original 1984 series.
In the second half of the first season, a small group of resistance fighters created a makeshift basement headquarters for their operations. In many of the scenes, the camera would pan over a table with a compter (or laptop) and two radios. Both rigs appear to be transceivers or transmitters. Can anyone ID these sets? Please comment!
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.
With front cover closed.
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.
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!
