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!

Here are two more great museum visits by Helge LA6NCA. In these two he visits Ragnar LA1UH.
Ragnar has a lot of maritime experience, so we see a lot of older ships' radios. But his interest in the radio art is much broader and we also see a lot of other kinds of gear:
-- Wow, a "travel radio" in a suitcase from 1927. Was this the idea that later lead to the Parasets of WWII?
-- Lots of "Stay Behind" gear from the Cold War. That "Africa" receiver (that never made it to Africa!) is very interesting.
-- We see an ART-13 with autotune, ANGRC-9s, several ARC-5 command sets. I was hoping Raganar would fire up a Dynamotor, but no.
-- I spotted a Galaxy V transceiver. I have the VFO reduction drive from one of these in my homebrew 15/10 rig.
-- We see several variometers in the emergency (500kc?) maritime transmitter. I used a variometer in my super-simple ET-2 transceiver (with an N0WVA receiver).
-- Lots and lots of tubes.
Ragnar says he himself is of 1944 vintage. I hope some "stay behind" provisions have been made for these amazing museums.
Brace yourselves. This is just too much, too much radio history, too much cool stuff. We are into ham radio sensory overload territory here. The rigs, the radios, the radioactive stuff (including tubes!). Lots of Whermact stuff. A Chinese receiver. Tesla coils and Faraday shields. Much more.
Thanks to Helge LA6NCA for alerting us to this and for shooting these videos. And thanks to Jens OZ1GEO for putting this magnificent collection together. I hope they find sometplace to keep this all together so that future generations can benefit from it.
George WB5OYP points out there is more from Jens here:
FB Helge. This is really cool. I didn't realize until I saw the schematic at the end that he was on 3579 kHz -- that is the old color-burst frequency, and now the frequency of the Color-burst Liberation Army.
It was challenging to do this without sidetone. But there appears to be a bit of room left in the matchbox -- could he squeeze in a few more components for a rudimentay sidetone? Maybe just a piezo buzzer across the key?
