I've been fooling
around with RTTY for a few days on my K3. It was working fine yesterday.
I even made a contact and was told I was loud and clear, but today I'm
having a problem on receive. The K3 is in DATA mode and set to FSK
D. It was in this mode yesterday. I have the DUAL PB turned
on. I'm able to tune in an S9+ RTTY signal easily and have it decode on
the K3 screen solidly. I have MMTTY (latest version) running on my
computer. When the K3 is in DATA mode (whether DUAL PB is on or off)
the audio from the radio to the computer is virtually nonexistent. The
audio from the K3 speaker is loud and clear. This is while the K3 is
decoding the RTTY perfectly on it's screen. I have CWT turned on and the
LCD segments are centered. FC says * 1.35 and is not movable. If I switch
the K3 to LSB, the audio to the computer is is now loud and decodes perfectly in
the MMTTY screen. LIN OUT is set to 15 and seems to be more than enough
for MMTTY. I touch nothing else but the MODE. This didn't happen
yesterday. Yesterday while in FSK D DATA mode, the audio to the computer
remained loud and clear. It's almost as if today the K3 isn't putting out
audio when it is in FSK D MODE or that the filter is somehow
shifted.
