data modes (USB/LSB or DATA) using KIO3B sound card interface

I looked in the K3S manual, and the instructions on setting up data modes
(p. 33) fail to mention the use of the KIO3B internal sound card. Are there
instructions (erratum?) available on how to set up data modes (using DATA
or USB/LSB) with this new feature?

Probably a simple answer to this question -- I'm just having trouble
finding it.

Thanks!

John,

That K3 internal soundcard should appear to the computer just like any
other USB soundcard. That can be computer dependent, so no specific
advice can be given.

Select that soundcard in your data mode application and you should be
"good to go" other than adjusting the soundcard levels.

Use DATA A rather than SSB because the K3 automatically turns off
compression and sets the TX EQ flat.
Adjust the soundcard output audio level to drive the K3 ALC meter to 4
bars solid with the 5th bar flashing, and you are ready to transmit.
Adjust the soundcard input level to suit a reasonable display on your
application's waterfall.

In reply to this post by John Shadle

I have the K3S USB cable connected direct to one of the USB ports on the
computer. As to radio set-up, see page 33 of the manual for details. I
use DATA A mode for PSK & other data modes. The software is usually
FLDIGI, HRD/DM780 or WSJT-X which all work under Windows 10 successfully
and do control all aspects of the radio. The DATA A mode is not the
typical or normal USB/LSB mode in that it releases any TX EQ and CMP
values used for SSB.

The computer Device Manager reports the radio under "Ports (COM & LPT)"
as "USB Serial Port (COM 5)". Depending on your computer, your port
number may be different.

Audio, PTT and CAT control of the radio is handled by the single USB
cable installation. None of the rear panel connections are used other
than the USB port on the radio.
