[Yaesu] frequency calb problems wit twins

Couldn't be that far off and still be in the band or make a contact. You
mean Hz, not KHz I think. Such offset is often from RIT being enabled OR 
different ears and the way you tune SSB. I'm not intimately familiar 
with the twins, but this also happens in Collins S-lines when the 
transmitter and receiver BFO crystals have drifted. It can also be a 
sign of the HF crystals not matching if they are both in use, one set 
for transmit, one for receive.
