Whether you find an interesting signal by clicking on traces in a
panoramic tuning display or by rotating your tranceiver's tuning
dial, ideally you should then direct your digital mode application to
place the selected signal at a pre-specified optimal audio offset by
appropriately QSYing

Additionally, depending on the filters, the signal may be distorted
enough to impact its decodability despite favorable SNR. Usually by
the time this is a serious factor, the actual passed signal is
obviously too far down, but I've seen it happen once well within the
passband of a particularly
There are two considerations:
1. the signal being decoded should fall within the receive filter(s)
you're using. Some ops activate RTTY or CW filters during PSK QSOs;
their choise of offset is thus limited by the positioning of these
filters within their receiver's bandpass.
2. the second
