[Elecraft] K3S fsk with usb

[Bill Frantz]

In contest mode, RUMlogNG (for the Macintosh) uses the cat 
commands (probably KY and TB) to send and receive RTTY (and CW 
and probably PSK). This places all timing responsibility on the 
K3 with no additional wires, boxes, or circuits.

There are a couple of "features" which are somewhat annoying:

(1) While you can chain sends in CW, chaining doesn't work in 
RTTY (very annoying).
(2) You have to turn off decode display on the P3/SVGA to get 
complete copy.
