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.
