[Milsurplus] Question ( RBS; submarine )

[Hubert Miller]

>From what i've read, and i very much welcome additional comments or
information, U.S.  submarines only transmitted when absolutely 

necessary, such as when making 'contact reports' - same as with scout
planes.  And, everyone was listening to everyone. The only jamming

incidents i have read about were very local, involved in particular combat
events in the Pacific. It would be pointless, due to high frequency

propagation, to try to jam a signal from a transmitter far removed from both
the sender and intended receiver. 

I recall reading in WWII magazine in a PT account, jamming by Japanese was
encountered. I may have posted that information here some

time back. There was also an article in 73 magazine, maybe CQ, that told
about an American force on an island, New Guinea?   The American

operator had a VFO with him, and once the Japanese jammer on the same island
settled on his transmit frequency, and was happily jamming

away, the yank operator quickly shifted frequency away, which went unnoticed
for apparently enough time for the message to be sent. 
In the Philippines there were something like 130 operating clandestine
stations, plus the island coastwatchers elsewhere. In Europe there

were also well over 10 reporting "spy transmitters". To jam those would have
required a lot of resources for a very unpredictable gain.

 

Here's on irony: the U-boats had a broadcast type radio, Radio R-2, which
never would have passed the FCC's strict reradiation specs for

onboard radio equipment.
