I'm using a CM500 that is a year or so old. It replaced one that finally
fell apart and I was tired of gluing it back together.
When I replaced the headset, I did not need to make any adjustments!
I went from a K3 to a K4 with the Yamaha headset plugged into the rear

I waited just over a year for my K4.
Having bought a K3 over 10 years ago, I have always been impressed by the
service from them.
BNC cables do have issues all of their own. First a manual connector seems
difficult for some to terminate properly (especially the shield).
Connectors have 2 sizes of center pins (50 & 75 ohm). Using a large
connector and then a smaller conductor will cause an intermittent at the
female center.

Seems that you are not getting the K3 IF output into the P3.

According to my KXPA100 manual (A2-2013) - "... tap *tune* again within 5
seconds. The ATU will do a second tune using smaller steps in inductance

All my Electraft ATUs have a similar feature. Downside - It does take much
longer to achieve the match.

In radio & TV broadcasting we used "Dry" contacts for microphone switching.

The contacts actually wiped a tiny amount as they made or broke.

Years ago we used 8 devices controlled from one PC com port on one RS-232

All of the devices bridged the receive line and were wire or'd for transmit.
The devices were polled by the PC and only allowed to transmit when polled.
This worked well with no conflicts for many years.
