Different ICOM, but same crystal? Might be the crystal itself wandering. I'm just learning about Mastr II systems, but I understand the various types of ICOMs have varying capabilities and functions. 1C - 1ppm internally compensated 2C - 2ppm internally compensated EC - Externally compensated 5C - 5ppm , internally compensated, and capable of also controlling ECs in the same rig. So if you have an EC, it may need a 5C (any freq, doesn't matter) in one of the other channel positions to handle the temp compensation.
