There may be a misunderstanding of how the digital modes work with today's computer software. Typically you leave the rig on a fixed frequency, like 7074, and "tune" the audio passband of 3kHz on the waterfall on the computer. It is really quite remarkable to see 20+ signals in the passband that would hold a single SSB signal
