John,
Use the coax, it is a faraday shield (ground only at one end).
Yes, even with coax, it should not be left plugged in - especially with
the KPA100 installed. The other transmit circuits may pick up BFO
harmonics from the wire and you can transmit spurs. It is not so much
of a problem with the K2/10, but with the KPA100, remove it.

Does the frequency counter probe have to be made with the RG 174 or will
regular stranded wire work. As far as I can tell the ground just goes to the
shielding. As long as I don’t leave it in the radio during normal use I should
be alright I think.
