Maybe. I doubt that leaky insulator noise generates the interference
described. It would not likely last for only 10 seconds with a 30-second
repetition rate.

Such an interference with different duration and repetition from Jeff`s
used to plague my company at Houma, Louisiana. Our offshore division for
the Gulf of Mexico was stationed at the Houma Airport. It turned out to
be caused by the U.S. Government`s radar. Every time it swept our way,
it broke the noise-squelch we used on our FM receivers, giving them a
click and a buzz. We all wanted to fly safely so we never complained.
