The only thing connected was the bird load and the DC power. I think the
problem is in the A to D or D to A chip or are they integrated in the DSP
chip? I assume that there's a mic amp in front of the A to D. It could
cause noise problems.

It's early Sunday morning and looking on my iPad at the K3 schematics
something was wrong. It appears that there are missing pages. I downloaded
the a new copy and was able to view the DSP schematic pages. There are
separate codacs and A to D/ D to A converters. There's also a mic amp.

While transmitting, my K3 developed a high level noise. During SSB with the
mic level set at 25, there's 30 watts output power. It sounds like digital
noise. It stops when the mic level is set to zero. There no microphone
connected and I just down loaded the latest firmware but that didn't
I'd suggest calling support on Mon AM.

Usually this kind of thing is external to the K3, very often
mechanical. Often happens when something external is rearranged.
Remove *everything* connected to the K3 except the power and a dummy
load. Make sure the power voltage is normal. See what you get then. If
you still have noise, put an AC
