I’m using SDR Uno v1.41 under Windows 10 to drive an ICOM IC-706MkIIG through OmniRig. I have added a 28 to 70 MHz transverter so would like to apply a 42 MHz offset within SDR Uno. From reading the User Guide I assumed that I could do this via the Ext Converter Offset function but this doesnt appear to do anything. Have I misunderstood this function?
