I am puzzled about why you would want to connect your code practice
oscillator to this output.  If you want code practice, just put the K3
into TX TEST and you will hear sidetone from the K3 as you key it - no
need for the external oscillator - but of course, if you 'just want to
do it', then by all means go ahead with it.

Why?  To set up a ducking test of course :-)  Here's the plan.

Set the K3 MON level set to zero (no sidetone).  KEY OUT connects to the
code oscillator which feeds the sidechain input on my external
compressor.  Feed the K3 audio into the compressor main input and set
the compressor to trigger when there is something on the sidechain
input.

So, when I send CW, the compressor hears the Heathkit oscillator and
compresses (attenuates) the audio output from the K3.

Using an external mixer, I can mix the compressed audio from the K3 with
the audio from the code oscillator.  The code oscillator will be
constant level while the K3 audio will duck under it.

Thanks for being an enabler :-)
