For those who are interested, I have added some updates concerning the secret WW2 radio shack, follow the menus for various pages.
The URL is https://sites.google.com/view/ww2-secret-radio-station
I am moving to the farm on a permanent basis in about 3 months, and progress will then be quicker...
The book "The Key Messenger" is progressing well. It is amazing what one can dig out about stay behind organisations (SBO's) today.
Anyway, have a look, I have started to add some download pages as well, and these will be updated with photos of receivers, transmitters, circuits, manuals etc.

This is really cool!
I wish you best of luck with your adventures in restoring such a site, and I look forward to reading your book.

I love the history of radio spying and alike. From one time pads to numeric code and huge bulky equipment all in a single base station with bulletproof walls and the smell of old electronics. Cold and dark, hidden in the middle of nowhere. That’s what my kind of radio shack eventually will be looking like. Inspiration is all around when just digging into it. :)

Ludwig, very nice job, it's a nice working museum, with all of the radios like they would have had them for a short period of time. It keeps the past alive, and people now and in the future can see what it was like.
Google sites, stay away they're news that you don't want to use. :(

I'll bet you make some amazing catches out there.

I've got a 1942 ARRL handbook that was put out for troops getting prepped for war after Pearl Harbor. A lot of the transmitters could get today's pirates in a world of trouble. Some of the receivers look pretty interesting, though. Everything from crystal sets to superhets.

Sounds interesting, is there a pdf version of the book available? Perrhaps you can scan it?

I suspect the ARRL would have it in their online archives.

That's it. I bought mine at an estate sale. There must have been a pile of 20 of them. The odd thing was there was nothing else radio related in the house.
