I would suspect that there is some pin/wire in that KPA/KAT cable which
is broken. When used for your purposes between the K3 and the KAT500,
it is not used, but is used for the KAT500 to KPA500 connection. It may
be wise to replace that cable at some point. I would at least put a tag
on it as a reminder that it is "flakey".

OK, new test results, followed by an inexplicable resolution to the problem!
I'm comparing the two elecraft-specific DB15 cables here, with the
suspicion that one of them is broken or defective.
1. *Physical observation*
The K3/KPA cable has all pins present.
The KPA/KAT cable has pins 1, 6, 7 missing. But it looks deliberate, and
those pins are not used anyway (according to documentation.)
I do not see any bent pins on either cable.
