K3 RTTY PROBLEM

[Elecraft mailing list]

I tried to get on the OK DX RTTY contest this weekend using my K3. I used  
N1MM+ with MMTTY and configured MMTTY as usual. Hit the TX button in MMTTY,
the  K3 went into transmit mode with no output!
I'm using FW version 5.01 on the K3.
I eventually resolved the problem, but don't know the reason for it! What  
happened is this: in MMTTY Config, I set the Mark (and HAM Default)
frequency at  2125 Hz, as I've always done. No r.f. output from the K3 with the PC
(and  interface) putting out the RTTY signal...
The solution was to set the Mark (and HAM default) frequency to 915 Hz (170
 Hz shift, of course!). That worked!
I swear I NEVER touched the PITCH button, never mind that I had never  
changed the Mark frequency there...BUT, there it was, big as life, 915-170! Did  
this parameter change on its own from 2125 to 915, or did this change take
place  with FW updating?
"Curioser and curiouser..." as Alice would say!

Bert,

I suspect that you did not have the K3 mark frequency set to match that
which was set in MMTTY.  The PITCH button will allow you to change the
K3 mark frequency to match that used in MMTTY.
