Jim, one mode will cause the audio pitch to increase with clockwise motion
of the tuning knob and the other will do the same but with counterclockwise
motion. Depends upon what you are used to and how you like to tune. Can be
used as a QRM fighting tool and also to demonstrate when you are tuned
properly on a station: his pitch will not change as you go from one mode to
the other.
This has nothing to do with what band you are using, unlike SSB.
And this was not in the manual?
