FT8 Transmit Problem

I'm having trouble with the I/F between Windows 10 and the USB sound card in
my upgraded K3. I've checked and the Sound Card settings in Windows 10 and
they are exactly as shown in Chapter 10 of Fred Cady's book. It receives and
decodes FT8 perfectly but can't transmit. When I hit the "Tune" button on
the WSJT-X screen the red "PTT" light comes on but there is no input signal
to the K3 and hence no RF output. What am I doing wrong?

Re: FT8 Transmit Problem

Terry,

This sounds like the same problem that Gary Smith was having. Look
through the posts of the last two days for subject line "Re: [Elecraft]
K3s can only transmit wsjt if the K3s codec is windows default."

Peter Lambert provided the solution. It is a Windows/WSJT-X setup
problem and not a K3/K3S problem.

In reply to this post by Terry Hines

I spent more time than I would like to admit trying to figure out why there
was no output when trying to transmit digital modes from the internal sound
card. It was the line gain (mic gain), it defaulted to 0 after installing
the KIO3B.
