[Milsurplus] What is a UF -1 radio

[rertman@ix.netcom.com]

In WW II, the frequency range from 30 to 88 MHz was assigned for
tactical use (PRC-6, etc.).  These, of course, were wideband (by
modern standards) FM radios.  I don't know if your UF-1 is AM or FM,
but, in the Pacific, clandestine coast watchers used HF for long range
and 30-88 MHz to communicate with ships and other watchers who
were just over the visual horizon.  Although they probably didn't
know it at the time, the reason they could use 30-88 MHz slightly 
beyond the visual horizon was the tropo scatter phenomenon.
