The electronics on Navy ships are not subtle. They pump out a ton of power on thousands upon thousands of frequencies. So sometimes such pedestrian electronic devices as your keyless car entry remote and garage door openers get jacked up when the Navy comes around.
The people of Bremerton, Wash., may have some issues this week, according to the Kitsap Sun, because the carrier John C. Stennis will be lighting off radars.
This is interesting because the Navy has long known the effects of its equipment on civilian electronics. AEGIS ships are required to shut down SPY within certain distances of land because of just these sorts of side effects.
The Navy is suggesting that people who are having these problems are using equipment that uses frequencies owned by the Department of Defense and should contact manufacturers to resolve the problems.

Yep, could always tell when one of the ships was rotating and radiating, since your car’s FM radio would give a BZZZ every time the radar swept past your location, even a quarter mile away!
