[Elecraft] RTTY using DATA mode on K3

[Wes Stewart]

I'm using the same setup.

Check the K3 pitch (Hold the "Spot" button) and verify that it's the same as the Mark setting in MMTTY.  I used 915 Hz since it's much easier on the ears and I can almost tune signals by ear now close enough to demodulate.  The downside to the lower tone is the possibility of more IMD on transmit.

Turn off Net and AFC.  I tune the K3 frequency using the MMTTY X-Y display.  (If I could turn off the waterfall I would.)
