One was an Expo 100 N board with two crystals and the other I'm not sure the brand but it used two IC's instead. The 122-xl had the expo board and that's the one giving me the most trouble. I repaired the traces on both radios at the clarifier, and replaced the D25 diode that gets removed or clipped when these boards are installed. I added a resistor to the clarifier on the pc-122 to help recenter the notch and that radio seems to have aligned alright. But it's just a band-aid.
