That's something I had to learn about from a practical, hands-on point
of view for my work in pro audio, and also as a member of the AES
Standards
Just made up a new cable of length approximately 15 ft. (That's the length
that was available.) It's foil-shielded, 4 conductor cable probably equal
or equivalent to that provided by Elecraft.
The KPA-100 / KAT-100 combination appear to be working normally. Is this a
new world record for
Chris,
I don't think you will get any smoke, but if you get strange
happenings - like the KPA100 is not recognized, or doesn't give a
response back to the K2 in sufficient time (command flow over the
AUXBUS) and things get mixed up or you get ERR 080, the cure will be
to shorten the cable.

While you may be correct about the noise pickup, there is also concern
about timing issues - if only because the performance has not been
tested at longer lengths by observing the bit timings on the AUUXBUS.
Some time back I had discussions with Jack Brindle about about extending

Of course, this applies to the K2. The K3 may or may not be different.
Thanks Don. At the very least, if this is a critical issue it

Jack Brindle and I just had an off-list email exchange in which he did
state that the conductor capacitance and resulting waveform distortion
may be a factor.
I really don't know the relative conductor to shield capacitance of the
4 conductor cable may be, but common sense tells me that
Just bought a fine used remote KPA100/KAT100 in an EC2 cabinet. It's neat,
but I'd like to put it under the operating desk, rather than beside the K2.
Can the K2 serial bus and the other 3 signals be extended for a total of 6
ft? Any problem remoting the RF by the same 6 ft?
Alas, the KPA100
Chris,
Why not try locating the KPA100/KAT100 at 6 cable feet from the base K2
and see what happens. There is no real information available on that
subject that I am aware of.
There are cautions available - those cautions say that there *may* be
timing problems on the Auxbus signalling - if
