[Elecraft] K3S - APF/RTTY question

[ae4pb at carolinaheli.com]

If I understand the question I'm in data AFSK A 45wpm, connected to HRD
DM780, I can hear the RTTY on both the radio and computer, I think I have
the radio tuned correctly because the Text is about 70-80% correct, I'm
seeing callsign and report most of the time. Computer shows no data, I've
done 45 FSK, 45 AFSK , both reverse, I'm not sure what I'm transmitting when
I try that as I can't hear it. I found the APF button, it was hidden right
in front of me :)

I did notice at first that I did NOT have RTTY audio at the computer.
There's a bug in the audio device settings where changing the sample rate
"fixes" it. Now I have RTTY audio but still no text..

On my earlier concern about possibly damaging something when connecting USB
and RS232: I opened up and removed all of the I/O boards, they all passed
the visual and sniff test, main board top and bottom pass visual and pass
sniff test. I have noticed that my Mag Loop controller is acting funny so
maybe I'll get lucky and that is it.

Jer,

Which DATA sub-mode were you in?  For RTTY, you would normally be in AFSK A
and then you could activate the dual tone filter.  I believe most use MMTTY
for RTTY, but HRD/DM780, Fldigi and other waterfall oriented software can
work as well.
In AFSK A (or FSK D) the K3 is in LSB (normal for RTTY) unless you activate
REV, and the K3 dial frequency is the mark frequency.  Make certain that the
mark frequency and rate in the K3 menu agree with your software application
settings.

Other soundcard data modes normally use DATA A where USB is the normal
sideband.

73,
