Re: no output on "line out"?

[Franki ON5ZO]

OK K3 "connoisseurs", I've got some more information on my RTTY / line out
problem.

- K3 + line out = OK.
- microHAM hardware and software = OK.
- I tune to an RTTY transmission and have the K3 decode. The tuning aid
tells me I'm right on. I'm not using Dual PB and listen 300Hz wide on a
500Hz roofing filter. K3 decodes 100%.
- MMTTY does NOT show a trace and plays dead. Hence me believing the line
output was dead or the input of the MK2R+ was broken.

BUT when I drive the filter wider, say from 800Hz up MMTTY starts showing a
signal. And when I listen 4kHz wide, I see the spectrum.
HOWEVER what MMTTY shows me is 'skewed', as if MMTTY listens off frequency
while the K3 is dead on. I played with Dual PB but that doesn't help either.
I consulted the manual but I missed the golden clue?
Does anyone use K3 Line Out to drive MMTTY? And does this occur?

TNX again de ON5ZO

Sounds like the MMTTY tone pair does not match the K3 tone pair.
