Hi guys....

OK....most of the radio manufacturers have very broadband RF sections on
their low to mid priced transmitters....those with no module.  You can
change the crystal in these...but, like horizon noted...i wouldn't go over
15 or 20 channels one way or the other...you will end up with too much of a
mismatch and high SWR...this limits the power actually getting out of the
antenna and the reflected RF doesn�t do the output transistor any good
either.  The transmitters with modules are usually tuned and matched to even
tighter tolerances so that changing a crystal may throw you into some high
SWR problems...the flip side is that since the crystal isn't "user
replaceable" it would make it illegal to change in the eyes of the FCC...and
by extension if after changing a module crystal you had a crash and hurt
someone, you would be guilty of negligence in the eyes of the law...with
federal law to back it up....they are not that expensive....buy a separate
transmitter module.
