Does anybody have a clue what this feller is saying or why he is saying it?
Why would the cable connector itself be more likely to have a failure than a
break in the coax shield itself? What does an electronic voltage regulator
have to do with it? Why wouldn't it burp with straight RF rather than
requiring the strobe to be on?

My hit is that both the strobe AND the transmitter are getting into the
engine analyzer, but neither of them of themselves are of a level to cause
the problem. HOwever, added together they rise above the trigger point.
I'd start looking at a way to put a filter on the A+ supply lead going from
the battery bus to the analyzer and see if this doesn't cure the problem.
Rat Shack sells "alternator whine filters" that may do the trick. At least
they are inexpensive and an easy try.

You have an RF leak from a com coaxial cable connector
somewhere. Probably a bad ground at the connector. This is a common
problem with electronic voltage regulators, as they are sensitive to
much smaller currents than mechanical regulators and will misread
interference as an overvoltage condition, and will drop the alternator
offline when the mike is keyed if there's any RF leakage.
Look at the connector at the antenna. Condensation in the
aircraft ceiling will corrode it.
