[Elecraft] K3/0 to K3/100 RemoteRig transmit audio problem

[Craig - AE6RR]

I am using a K3/0 and a K3/100 with the RemoteRig boxes.  I have the
standard versions as sold at HRO not the ones with the special microphone
jumper module.  I jumpered the mic connections as shown in the RemoteRig
manual on page 193 and I have horrible digital noise on my transmit audio
even with a microphone plugged directly into the control RemoteRig box.  The
PTT does work OK.

 

Any ideas on this one?
