This discussion has assumed that operators use ‘Hold Tx Freq’ selection and have chosen a ‘free’ transmit frequency for their potential transmissions including answering CQ’s.
If you want always answer with a small offset, say 10 Hz, you rig may have RIT or transmitter independent tuning facility and you could use it for that purpose already.
About the original title there is a nice feature built into wsjtx by which we could spread stations on a wider frequency range. We could use ‘directed’ CQ to ‘force’ an answer to your CQ to another spot. Just call on 20 m band e.g. CQ 077 OH3MA in my case. That would direct answers into range 14.077 – 14.080 instead of normal 14.074 – 14.077. See User Guide 17.1. Overview fourth clause. I have not tested what I need to do to make it work, hi!
73, Reino OH3mA
This is possible when I see a station and wait him to end QSO (73) to call him. But if I want to reply to a CQ I have not the time to enter my new Freq!
