Per page 31 of the K3 owners manual sez
DATA A can be used for all audio-shift transmission modes, including AFSK and
PSK-31. VFO A shows the transmit suppressed carrier frequency and USB is normal
for DATA A. Compression is automatically set to 0 to reduce transmitted signal
distortion.
Can you 'splain the difference between AFSK and DATA A? I have been
running RTTY in AFSK using MMTTY and the sound in/out from my radio
laptop. Just two stereo cables using LINE IN/OUT on the back of the
K3, no other interface hardware. VOX for PTT. It seems to work fine,
am I missing

AFSK A and DATA A are both audio modes. AFSK A uses LSB
and FC is set to MARK - 85 Hz (the center of the two RTTY
Tones). DATA A is USB and FC is set to 1500 Hz (the center
of the transmit
I have been running DATA A with my SignaLink USB for JT65 JT9 using
WSJT-X. However I am now having some problems (interfacing with other
rig control software) that are making me question why I settled on DATA
A rather than USB?
Other than the fact DATA A inherently eliminates all potential
You can use DATA-A to do LSB too. I do this when I set up the KX3 for packet
radio, because it places the LO just nicely so I can also monitor the local CW
calling channel and my club's SSB frequency, using a separate SDR app on my PC.

Hi Sam,
I can't think of a single good reason to use USB for data modes. Stick
with DATA A, which IS optimized for
Sam,
You are doing it right.
DATA A mode is like SSB with the following exceptions:
1) TX EQ is disabled in DATA A mode
2) Audio compression is disabled in DATA A mode.
3) one can set the audio input to LINE IN for DATA A mode - no need to
change it from MIC audio when using data modes.
