Even on CW or
SSB I doubt most listeners can even detect 100 cycles of instability.

I can definitely tell when some station is ten or more kcs off where I'm tuned,
and go to the RIT automatically. If they continue to drift, I might chase them
awhile, but usually move on, suggesting they sober up and quit leaning on the
VFO knob.

My receiver is stable to less than a twentieth of a cycle over several months.
(Using WWV as a reference)

100 Hz is a noticeable change in pitch. A 50 Hz step makes listening to
music on SSB very difficult. I do my major DXing through a 250 Hz
filter, so if you drift you go bye-bye.

My NRD-515 tunes in 100 HZ steps and SSB would be really annoying if it
didn't have the (modified) delta tune for pitch control. 10HZ is fine,
but 1HZ, is better.
