I use an audio scope when I run qrp cw to zero beat. I noticed that quite often QSO's are not on the same freq. by maybe less than a tenth of a khz. When I answer a cq I try to call the exact freq. even when its just a little off a more commonly used one (eg 7050). I was wondering in a transciever if the trans is off is the rec off the same? In other words if for example you have your transciever set to 7050.000 and you are really trns on 7049.95 do you rec on 7049.95 ? Obviously if you have vintage rig with separate trns and recv they would be different but do modern transvievers use the same freq control for both trans and recv. Just don't want to waste my little 5 watts of signal answering on the wrong freq the caller is listening on. I am not talking about DX up or down.
