I read in a HAM mag about US HAMs hearing panzer crews in North Africa on their often home-made gear and alerting the US gov to the fact, and how the US rushed to build listening posts (FCC RID) in various US locations where these comms could be received. The US HAMs talked with some of the crews, and each side was amazed to be able to communicate so far, but as each side were experienced radio ops they understood how it was possible. When the North African Wehrmacht radio traffic was first noted in the US, the US was still neutral and HAM radio was in full swing.
Do you have a reference to the part I put in bold?
The North Africa campaign started in mid June, 1940, however German tanks, and their universal use of radio equipment (and the source of most of the receptions I have read about), were not active there until after the Italians requested help, in late 1940. Most of the Italian M 11/39 and M 13/40 tanks did not carry transceiver gear, the ones that did (often only the command tanks) used the Magneti Marelli RF1CA and later 2CA. The 1CA did cover the right frequency range.
By late 1940, or even mid June of 1940 (at the start of hostilities in Africa), despite the US being officially neutral, the restrictions on hams were in place to NOT communicate with anyone outside the US. Anyone admitting to talking with these tank crews would be in violation. I have heard claims that this happened, but always it has been a case of "this guy told me that some of them did it" with no documented or contemporary sourced references.
Most of the accounts of hearing Africa Corps communications in the US that I have read were stated as being in 1942 and on the US east coast. By that time the "no ham transmission" restrictions were in place.
And yes, the Germans did allow some ham radio operations during WW II inside Germany. Operation inside occupied countries was not allowed. Inside Germany all ham operations were ordered halted, and licenses rescinded, with the invasion of Poland in September of 1939.
In early 1940, possibly as part of a "sustainment of normalcy" effort, Germany started relicensing a limited number of stations. By mid year 1940 about a dozen ham stations were licensed in Germany. It appears that at no time during the war did the number of legal ham stations in Germany exceed 200, and for the majority of the conflict the number was under 100. I suspect the people allowed operation were deemed dependable to the administration, however little can be found on the selection process. Also it is possible that everyone, hams and "legal" SWLs, may have been required to keep 2 logs, and send one of them to authorities periodically for analysis. I have seen indications of this requirement, but no one has been able to show me what German regulation stated it.
It is worth noting that the Brits allowed some hams to be active during the later stages of the conflict, and there are reported (but not well documented) cases of British hams in QSO with German hams.
Oddly enough, the US and allies only restricted citizens descended of enemy nationals from using short wave receivers, not the population at large and many US citizens actively sought out enemy broadcasts to gather info on captured US service members who were often mentioned in such broadcasts for propaganda purposes. Then the listener would write a letter to the family of that service member and relate the enemy broadcast details.
I do not think the US restricted citizens descended of enemy nationals from using short wave receivers. The US restricted foreign nationals (not citizens of the US) in country from such use (via Presidential Proclamation 2525, ss Regulations, 5(f), 2526, and 2527), but not US cits descended of those nations. 2525 addressed Japanese, 2526 addressed Germans, and 2527 addressed Italians. Lets keep in mind how many millions of first generations Americans in 1940 were descended of German and Italian stock or even naturalized US citizens from those countries.
Because of the bias of the time, both caused by the attack on Pearl Harbor and existing racial issues, these regulations were also applied to some US citizens of Japanese descent, however this was a overstepping of authority (the proclamations were specific to aliens, not US cits).
This is not to be confused with Executive Orders 9066 and 9102, these orders did not restrict radio use, but did allow for the internment of US citizens of Japanese, German, or Italian descent. Only a very small fraction of German and Italian descended US citizens were impacted by these events, while a large percentage of US citizens of Japanese descent were affected.
