Speaking of interference, our campus is about a mile from the Santa
Barbara airport. We get interference from the airport radar (we think).
It's cyclical and we've ruled out just about everything else (elevators,
fluorescent lights). It's only picked up by things that are microphonic
like phono cartridges and doesn't affect the shielded balanced lines. If
you listen very, very carefully to our cylinders you might be able to
hear it.
I attended Hofstra University in the mid-'50s. Mitchell Air Force Base was
across the highway. Sitting on the second floor in the student lounge,
through a radio which was NOT on, I would hear a Zummm sound every time the
airport radar swept the campus.
