[Milsurplus] BC-1000 The Fun begins

[Ray Fantini]

Just personal observations from working nets with all the radios. The BC-1000 always sounds way over modulated. PRC-6, PRC-10 and the RT sets from the fifties are wide but nowhere near as wide as the 1000 and newer sets like the PRC-25, 77, VRC series radios are usually around 15 to 25 kHz with around 2 kHz to 5 kHz of PL. On my PRC-68 I can copy all of the above with little or no issue except the BC-1000 that always sound loud or off frequency. Don't know what the IF filters is on the PRC-68 but think it's an issue for netting with the old sets, I have also used my Russian R-107 couple times at Dayton and think I remember that the BC-1000 always sounded better on that. The BC-1000 is a great radio considering when it was designed, built and fielded and cretin with working with all the old SCR series FM radios frequency stability and bandwidth were not issues but would think it may have had a very short service life and was obsolete as soon as the PRC-6, 10 and RT-68, 70 families of radios were brought out in the fifties. They do appear to have been sent too many other countries so maybe that was a way of getting them out of our inventory?

All of the Korean War and WW-II vintage FM sets are what now in unsecure 
communications equipment is considered wideband (the AN/PRC-77, and later 
versions of the AN/PRC-25 and RT-524, on the other hand, will do 100 KC).  
However, the deviation is adjustable or at least changable.  And part of the 
problem with the BC-1000 may be that the owner used a high output or amplified 
microphone instead of the original carbon or one with output levels matching 
it.
