You don't even need the Audio PA 12 Volts if you don't
want or care for local speaker audio.
There is such a glut of used surplus radio equipment on
the market right now that I doubt many people will bother
with using Master Pro-Receivers when a crystal has to be
ordered for each frequency change.
Of recent surprise to me is how much GE Master II stuff
is flooding into the used radio market and how dirt cheap
it is...
I've even started to see Master 3 equipment coming out to
hit the surplus market and Ebay... selling for a lot less
than I would have suspected they/it would.
The trouble is... fewer people want to go the surplus
equipment route. And for political reasons I won't throw
out why I think that's a real shame (and part of what is
really wrong with much, not all of the American Mindset)...
cheers,
