Hello Ive got and old sideband cobra 134 (says 138a on back) thats 23 channels. Is it possible to add more channels to it. Would i just swap the crystals for the ones i want to add ? Its board has pc003aa on it. Thanks , Mike

Yes, you can swap crystals. If memory serves me, you can change a mixer crystal in that radio, that will give you a whole new 23 channel group. 23 channel radios are not very wide banded however, so I would not try to go too far.
