[Elecraft] K3 and N1MM using RTTY and PSK

[Fred Jensen]

I don't know much about Rigblaster Advantage, or Microham, or Signalink 
[OK, I don't know anything about them], but you might try the "back to 
basics" approach and get 2 stereo cables and connect LINE IN to LINE OUT 
and vice-versa, and go AFSK [DATA MD A].  I do this using the MMTTY RTTY 
engine in N1MM, I key the K3 with VOX [be sure to turn off all the 
annoying Windoze sounds, and N1MM can be configured to assert PTT for 
you if you coordinate it with the K3 menu options].

In AFSK with MMTTY, you have several discrete choices of MARK/SPACE 
tones [PITCH knob], I use 915Hz because I can hear it, and MMTTY must be 
set to the same.  You have the Windoze audio level controls, and those 
on the K3, and there's a combination for just about everyone.

This may not be the ideal situation for everyone, but it is pretty 
basic, it removes many of the points of failure, and honestly, it worked 
so well for me, I've never gone beyond it for RTTY [and PSK, although 
that's not a mode I enjoy].  I've used it for JT65, another mode I only 
enjoy when I sort of like my mind to wander while making Q's. :-)

My experience with trouble-shooting problems is, "eliminate as much 
'stuff' as you can and see if the problem remains."

Best of luck, I've finally gotten to the point where I can go from my 
"normal mode" [CW] to RTTY in less than 30 mins.  I use the totally 
back-to-basics AFSK technique.
