Generally speaking, transmitters traditionally, at least in recent history,
have been the only radio devices that needed to be licenced while recievers
were not.
I would think that swapping is not FCC approved as you would in all
probability your transmitter would no longer be properly tuned to the channel
of your xtal and would be in violation of being off frequency as well
interference
on adjacent channels and possibly spurious signals out of band (ie harmonics).
So, to swap xtals in transmitters you would need to have the transmitter
adjusted
to its new frequency which would have to be done in a radio by someone with
the proper equipment

Are the shadows there for me to find, or placed there by my searching mind.
When I reach and find them gone, was I right or was I wrong?
