[Elecraft] K3 RTTY setup with MMTTY

[Julius Fazekas]

I'm running into problems interfacing my K3 with MMTTY on transmit.

First, I'm unclear as to whether a keying interface (simple NPN 1K combo) is needed for the FSK IN and DTR? I am guessing that FSK IN comes from the TXD line out from the computer and DTR from the DTR out.

Then under the COM Port Radio Command, I'm not sure what needs to be specified. Do we chose Kenwood (like N1MM in the old days) or does it require something special?

How easy is it to damage the RS-232 / AUX I/O on the K3, if one makes the wrong connection?

Frustrated in Tennessee,
