Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
A highlight from last week was attending a WWII encampment at the Museum of the US Air Force.
SWLing Post readers: If you’ve tried to contact me in the past week, I’m sorry if I haven’t replied yet.
I spent a week on the road attending the 2018 Hamvention and as soon as I arrived back home on Tuesday, I started more family travel. I’m trying to catch up on on email and posts this weekend. I have a number of small announcements, so stay tuned and thanks for understanding!

Listening Sessions at a Prague Cinema: Czech Radio’s First Broadcasts Recalled, 95 Years Later
A historic moment occurred at 20:15 on Saturday May 18, 1923 when the first ever broadcast by Czechoslovak Radio was made from a tent at a military air base in Prague’s Kbely district.
After the United Kingdom, Czechoslovakia was the second country in Europe to launch regular radio broadcasting.
Zuzana Foglarová is communications manager at today’s Czech Radio. Speaking at a new exhibition of radio technology at the station, she describes the scene in May 1923.
“Above all it was very simple. There was one tent, which had been borrowed from the scouts. On the floor in the tent was a piano and stool. There was also a table for the presenter, technicians and so on. There was only one microphone, and the story goes that if somebody was playing the piano and somebody else was singing, the latter had to sit under the piano so the microphone could pick up all the sounds.”
Many of the first listeners 95 years ago were waiting to hear the signal come through at a cinema just off Prague’s Wenceslas Square.[…]

Past and Present: A Gallery of Czech´s Radio Buildings
Czech Radio is celebrating its 95th anniversary this year. The Czech national radio broadcaster has come a long way since its pioneering days. Today it is the biggest radio broadcaster in the country with 9 channels, manned not only by its Prague staff but 14 regional branches providing news and reports from around the country. The station’s buildings are also an important part of its history. On the occasion of Czech Radio’s 95th anniversary we have prepared a photo gallery of its buildings, some of them valuable architectural landmarks.

Collectors of classic boatanchor gear know what has been probably the rarest of tube sets year after year, decade after decade. That set is the Hammarlund SP-600 JX21A.
While there have been numerous JX21s on eBay, there has not been, to my memory, a single JX21A appearing. This particular model was a version of the SP-600 that was produced in small quantities in the 1960’s, and according to one writeup was the only one with a product detector and switchable sidebands. According to Radiomuseum it was the last model in the SP-600 series, and was recognizable for its knobs which were different because the silkscreen information was printed directly on the front panel rather than on the edge of the knob skirts.
Now, an ultra-rare SP-600 JX21A has appeared on eBay. Like other models in the series, this would likely require replacement of numerous capacitors and a thorough refurbishment. The seller in this case has started bidding at a very low level, but if history is any guide, a rare model like this one may indeed go for thousands of dollars when all is said and done at the end of the auction.
Amazing! Thank you for sharing, Dan! What a gorgeous set. Though the seller states it’s in need of restoration, I’m pretty sure this one will get snagged up at end of auction. I’m very curious where the final price will land.
Are there any SWLing Post readers who own an SP-600 model–or the JX21A? Please comment!

Saturday and Sunday were long (though fun–!) days at the 2018 Hamvention–I did have a moment to visit most of the inside exhibit tables. Most of the following photos were taken (in no particular order) in the main Hamvention buildings and tents at the Greene County Fairgrounds.
Again, it was especially fun meeting so many SWLing Post readers and contributors in person!
It was a long day at the 2018 Hamvention Friday, but we had a brilliant time. As always, it’s a pleasure to meet so many SWLing Post readers and contributors–thank you for stopping by!
Below, I’ve posted photos I took at the Hamvention Flea Market this morning. Note that most of these photos were taken either prior to the flea market opening or just shortly after. The selection was pretty amazing. The rain did come and go throughout the day, but the recycled asphalt that was spread between the aisles did help keep mitigate the mud situation.
Click on the thumbnail to expand each photo. I’ve tried to include price tags when available although the camera phone I used didn’t have the sharpest focus! I plan to post inside exhibit photos tomorrow.
