Dale, Let's face reality. Only 35% of the hams on the air know how to zero-beat (maybe it is 20%, I have not taken a poll). They just trust that their transceivers will do the job for them - if they can hear the other signal, then they assume they will transmit on their frequency - without regard to how far off the center frequency they may be.
I have had K2s here for repair where the operator said he wanted a 750 Hz sidetone pitch, but I discover that he has the ST P parameter set for the default of 600 Hz, That is an automatic 150 Hz misalignment of the received pitch and the transmitter offset. Tell you K1, K2, K3 the sidetone pitch that you prefer to listen to, and set the menu for that same sidetone pitch. Those transceivers (and many others) will offset the transmit frequency by the frequency that you have set in the menu. So the remaining problem is to tune the desired signal in at your chosen sidetone pitch - some do that well, and some do that poorly. We have lost a lot in moving from separate transmitters and receivers to transceivers. Sure the Transceiver can do it "automagically", but it all depends on the parameters you have set into the transceiver. Yes, I have even heard some "old-timers" who knew quite well how to zero-beat using separate transmitters and receivers that have become confused with the concept of zero-beating when using a transceiver. That is just sad to me, but has to be dealt with as a "fact of life". Know your transceiver and know your operating conditions, and set things up accordingly -- in other words RTFM. 73, Don W3FPR On 1/31/2011 7:07 PM, Dale Putnam wrote: > I wonder, wouldn't pass band tuning do well at that too?
