Re: FO29/FO20 blues


I am not sure from your post, but if you just set your transmitter on 145.95 and your receiver on 435.85 and then transmit while not moving either vfo, I would be surprised if you heard your signal. Doppler shift will cause the relationship between uplink and downlink frequencies to be inexact. You must tune one of the vfo's while holding the other steady until you hear yourself.  

My preference is to find a clear receive frequency and then transmit while adjusting the transmit vfo until I hear myself in the receiver.  That way, if I start to transmit where a QSO is already at least I won't be there long enough to cause trouble while I am finding myself. I also have found it easier to find myself on cw first and then switch to ssb for fine tuning.
