[Elecraft] RE: K3 - should data via the RS232 cable work?

  The FSK data mode works with KY commands but not the PSK data mode. I 
have used FSK with command macros in Ham Radio Deluxe.
  The DM780 digital modes program, also from Simon Brown, now also 
supports keyboard CW on the K3. Maybe with a little lobbying Simon will 
support keyboard RTTY and PSK for the K3.
