[Elecraft] K3 w/KIO3B has confusing RTTY transmit behavior

[Joe N9OK]

Can't figure out how to reply to your post Rich in your thread.
Audio Mark and Shift in MMTTY are identical to the Pitch control settings
in my K3.
MAIN:AFSK TX is set to Filter On. This makes no difference for my transmit
power, however.
