[Elecraft] K3 "CW via CAT Command"?

[Doug Faunt N6TQS +1-510-655-8604]

Hi, I'm using MixW with my K3, configuring it as "K2" under Kenwood
for CAT, and decided to try the "CW via CAT Command", since that seems
to be similar (I think).  But it doesn't send CW- it puts the rig in TX, and
something is happening, I can hear some sort of artifacts coming from
the speaker, a click for each CW element (adjustable by the volume
control).  But there's no RF shown (and no I don't have the radio in
"test").

I know I'm out here on the bleeding edge, but wonder if anyone has any
ideas about the problem.
