Mark, I saw the radio of my godmother Clara and her husband Sam with the SW function removed. Sam had Italian ancestry.

Here they are, after a bit of searching, Presidential Proclamations 2525, 2526, and 2527:

I remember the earlier discussion, but could not find it. Maybe it was removed.

My parents suffered through Nazi occupation of Holland, where starvation caused my mom, in her late teens, to lose her teeth. Radios were confiscated. So be it. My uncles had a hidden radio.

I copied this from an antique radio forum, and I imagine these are Philips, but please enlighten us if you recognize the chassis in this stack of radios:
The text of this photograph reads as follows: On 13 May a decision of Rauter was issued in the Netherlands, in which, with reference to police law, it was determined that all radio equipment and parts thereof were forfeited and had to be surrendered. Only Germans, NSBers and a few treacherous categories were exempt from the surrender requirement. The radio distribution, on which only Hilversum and Germany could be heard, remained. The Germans soon became clear that not everyone met the surrender requirement. Rauter thought it necessary to publish an additional warning, in which evaders of the surrender requirement were threatened with a properly functioning "control system".

Hugo Sneyers

The back walls (if present) were removed to determine if a complete device was returned. Some removed (vital) parts in order to do so, for example; to build a 1-lamp receiver, usually on the instructions of the resistance, which also published and / or distributed the diagrams. It was n.l. impossible to casually enter a radio case to ask for radio tubes and the like unless the owner was a member of the N.S.B. or an affiliated German organization.

Harm

Radios also had to be returned in Belgium. Read on: http://www.mers.be/1940-1944.htm. Small quotation: In Belgium, the Military Commander issued a regulation on 4 April 1944 in which the municipalities of Lier, Duffel, Heindonk, Waelhem and Klein-Willebroek were to keep radio equipment in great Antwerp, the district of Antwerp. However, the ban does not apply to radio distribution. After all, radio distribution only broadcasts permitted, censored programs. The delivery of the radio equipment must take place before April 18, 1944. A ticket, large 10 x 15 cm, must be attached to each delivered device, stating the make, model, number and if necessary the purchase price of the appliance, as well as the name, the profession and the address of the owner.
The information on this website does not make clear whether this was only applicable for Antwerp and surroundings, or also for the rest of Belgium.

I have a Silvertone console with the band selector contacts soldered in place on AM.

It is always interesting reading those old magazines. Did you read the links I posted above?

Yes, that letter would be interesting. Have you asked the Justice Department for a copy?

Here's my 1938 Delco R-1127 with a snipped dial pointer. SW is completely dead.

I was searching for a schematic in my Riders set a few years ago and found a page where the service man noted the changes he had made and include the customer's name.

They still use that method, and it has numerous advantages, specifically, it's more or less impossible (or at least very difficult) to track down the recipient. Almost anything else is traceable.

They do indeed. Over the last year I have heard two numbers stations. One was a female using English with a Spanish accent. She gave blocks of letters and then a short burst of some sort of digital mode. The other was a male voice, English with an American accent. He gave out just numbers and at the end said "Mud Duck Out".

Pretty cool to hear. And if I heard two in one year while noodling around occasionally they are out there.



The Cuban Lady is a well known numbers station. The data protocol is rdft, you can dl the program and see the figure/letter groups but I suppose the groups are encrypted via one time pads, meaning nsa level efforts to decrypt the message. The guy whose callsign was mud duck was likely a USAF radioman, sending eams.

Thanks for the info! IIRC it was an AM signal in both cases, but Mud Duck might have been sideband. Good to know that the digital is RDFT, I'll get a copy of DIGTRX to play with. Why? I dunno, it is cool and better than a decoder ring. :-)

You will not decode anything done through a one-time pad.

Define "you" however you wish...
My comment is equally valid regardless of how you define "you".
