Thank you Jim! Are you saying to use AFSK A for all sound card modes?
No, only for sound card RTTY.
Note also that like MMTTY, the K3 can be set for several tone frequency
pairs. I use the lowest of them, 915/1085 Hz, because I find it easier
to tune by ear.
Some RTTY folks don't recommend this, because the second and third
harmonic can get through the TX filter. What they fail to realize is
that the same mechanism that creates harmonic distortion also creates
intermod distortion. So careful level setting throughout both the audio
and RF chain are critical for all audio and data modes.
