For a long time, I've had problems with the two RX losing sync in diversity 
mode. Symptom is that one RX is several hundred Hz from the other after a 
transmission. Wiggle the RX RIT knob and they re-sync. 

I've corresponded with Wayne on this. He has no ideas why, and has not been 
able to reproduce it. One hypothesis is RFI. It only happens on 160, and my 
TX antenna is only 25 ft from the shack, with only wood walls in the way. It 
happened only a few times this weekend with 100W, but a lot more often 
running 1.5kW, so RFI might be part of the mechanism. As you might guess, 
I've got mondo coax chokes in line. :)
