I have been enjoying operating my K3 for several months. One of my interests
includes RTTY.
I use the latest MMTTY software (AFSK), have the two audio lines connected,
and use VOX to operate this mode. At the same time, the serial cable from
the computer to the radio remains connected.
Doug,
The K3 is capable of detecting and using DTR and RTS to operate either
the KEY or PTT. See the CONFIG: PTT -- KEY menu item.
There is one downside to using these inputs (it also applies the the
simple keying circuit in many digital help files). If the computer is
booted while the K3
See the K3 manual documentation on CONFIG:PTT-KEY for using RTS and DTR on
the serial cable for PTT and Key lines. Use the PDF search in the PDF
reader function to look up PTT in the manual PDF for a quick find.

Doug, the answer is yes, but the details depend on whether you are using
MMTTY stand-alone or from inside another application (like N1MM Logger
or Logger32).
If you are using MMTTY from inside another application, the easiest way
is to let the parent application handle rig control and PTT. The

I use the 200/250 Hz bandwidth only when I really have to. In SP mode on a

You will need the KXV3 or -3A to bring out the IF to the P3. The

You plug the PC into the upper 9-pin D-shell connector on the back of the
