[CW] Sidetone frequency versus transmit frequency

[D. Chester]

The best method of all, still, is to use a separate transmitter and 
receiver.  No problem then, telling whether or not your VFO is zero-beat 
with the other station, assuming the VFO stays put and isn't "pulled" when 
the transmitter goes into transmit mode.  :-)

I have monitored QSO's, both in SSB and CW, in which there was a slight 
frequency difference between TX and RX.  Each time, the receiving operator 
retunes the transceiver to his preferred tone or voice quality, which pulls 
his signal off frequency for the other operator.  So the other op then 
re-adjusts when it is his turn, and the process continues as the QSO "walks" 
across the band step at a time,  maybe tens of kHz, and possibly out of 
band. This was particularly common with early transceivers that didn't have 
the RIT feature.
