A two-way radio system is being deployed by the Department of Defense at military bases nationwide that allegedly is jamming garage-door openers in the affected areas, according to the Chicago Sun-Times. The radio system operates on a 24-hour basis in the 380 MHz to 400 MHz range, while most garage-door openers operate at 390 MHz.

The Sun-Times reported that most of the complaints from homeowners in Florida and Pennsylvania, where the system already is deployed, came within a range of 8 to 10 miles and 1 mile from the tower site, respectively. The Great Lakes Naval Base, north of Chicago, is scheduled to deploy the system in 2007, the paper said. According to the Safe and Secure Access Coalition, about 50 million garage-door openers nationwide operate at 390 MHz.
