Just acquired from an old lady her old CB transceiver. It's rather old;
crystal controlled. Is it feasable to swap out the 27 MHz crystals and
replace them with 10M crystals? Is there a source for these crystals?
And would any major modifications to the rig be required?

Any info would be appreciated (and yes, I hold a Technician class
license).
