In the NAQP RTTY contest I had a similar issue. My computer was
decoding RTTY quite fine on every band but 15 meters. The first
time I tuned a station on 15, the tuning indicator was right and
the station was strong, but no decode. At least I knew that
RTTY, unlike PSK, isn't symmetric. I turned on "Reverse" in the
computer software and got decode. OK, it worked. I didn't try to
find out why until later.
What I found was that the K3 was in Data A mode on 80, 40, 20,
and 10 and in AFSK A on 15. For some reason the K3 was using
different side bands in the two modes. Reading the manual, AFSK
A is probably a better mode for that contest because of the
duel-tone RTTY filter.
I never did get the K3's RTTY decode to work for me. However
decoding on the computer is an advantage because I can copy
calls directly to the logging program and my dyslexia doesn't
have a chance to swap the letters. :-)

Lots of interesting options on the radio that are band

won't miss this one next time. I know it's the first thing I
check after missing it once!
