Hi Jim
Here is the setup:
rig A:
K3
heil proset on front panel
pc audio on rear plugs
cat plugged via microham microkeyer
nothing plugged on cw key jack (that minimized rfi a bit, it was
coming from microkeyer)
JRC 1kw amp
rig B
ft2000
cat cable to pc
icom pw1 amp
The antennas are all near the shack.
When rig B TX, depending on band, it gets into K3 TX audio.
