Andy,
While you seem capable of reverse engineering the AUXBUS, it is fraught
with danger if you get it wrong.
You are "own your own" in this matter.

Don,
Thanks for the reply.
I'm familiar with the PC interface and have, in the hope of tracking
down a problem, built a logger that uses that bus to interrogate the
KPA500 at 10 Hz. I was hoping the AUX bus would give a faster
detection of a spurious band change than my 10 Hz interrogation ^bn;.
I'll look at the bus with my DSO but I have already been given
information than suggests its data rate will be too low to be useful.
I may have to resort to instrumenting the shift register signals from
the front panel to the LPF but I was hoping to avoid that.

The AUXBUS protocol is Elecraft proprietary and is not published.
It is the single wire communications between the K3 and its options,
both internal and external.
The K3 Programmers Reference and KPA500 Programmers Reference gives you
commands that can be issued from a PC or other connected computer -
those commands are quite extensive and can give you complete control
from a PC.

KPA500 - K3 AUX Bus. I have the KPA500 Programmer's Reference but
this appears to only cover the KPA500 - PC interface.
