[Elecraft] Ham Radio Deluxe and KX3 Radio

[Rick Bates]

DM780 does indeed allow CW (KY Cmd), which should work on the KX3 as well as
it does on the K3.  It does this through the serial port, which also manages
the PTT, no further hardware needed unless you want it to decode for you as
well.  ;0)

The KX3 can be keyed using the "KY" command, but I do not think 
HRD/DM780 implements that command - few applications do.
The easiest solution is to use the K1EL Winkeyer.
HRD/DM780 can also send CW using a serial port, but that is a different 
port than is used for rig control, and you need something like the 'one 
transistor keying interface' to make the RS-232 signal levels into 
on-off switching needed to key the rig.
