I appreciate all of your thoughts.
And the "thinking" questions, helped to understand what I was trying to do
better.
I believe your understanding the "problem" better than I do. I'm Good.
VOX terrifies me, it can really mess up a net if left on accidently and the
phone rings, we had to m
It occurs to me that another option might be to connect the footswitch,
with a pullup resistor to 5VDC, to pin 7 of the ACC connector, and set
CONFIG:TX INH to HI=INH. This should prevent the K3 from transmitting
except when the footswitch was pressed. You might want to wire an SPST
switch in paral
An alternative if one is using an electret microphone is *not* to apply
bias from the K3, but to bias the microphone from a 10k resistor fed
from mic jack pin 6 (to mic jack pin 1). Put a relay in series with the
resistor and operate that relay from the foot switch.
The microphone will not res
I think it's an interesting idea. It seems it should be feasible to
implement in firmware, but maybe non-trivial.
Thinking outside the box; what if you route the mic signal through the
footswitch instead of PTT? Or maybe through a relay that the
footswitch triggers... and keep VOX on all the time.
I think the point is to have VOX inactive until PTT is keyed. In this mode,
PTT wouldn’t key the radio, it would simply activate VOX. If PTT was not
keyed, the radio would not respond to audio and key the transmitter, even with
VOX turned on.
Another way to do this of course, would be a switc
Is it possible you have confused PTT and VOX? I can't imagine VOX being
controlled by a foot switch.

I wish to manually key the transmitter with VOX, and while transmitting have
the VOX activate to LISTEN between words so that I can hear if I double.
I don't want VOX on all the time to key the transmitter when I sneeze,
someone talks to me, I murmur, phone rings, wife pours hot soup in my lap,
