Some wireless Devices can cause mayhem

Careful with buying unregulated non FCC certified devices. A house in mill creek Wa reported that about 3 weeks ago wireless key fobs for their cars and the garage door opener stopped working.. On further investigation it was found that it was affecting at least 3 houses. After 3 weeks a radio frequency sensor was used to home in on the source of the interference. It turned out to be an inexpensive door bell extender bought from amazon.com. The small device was push enough interference in the 315mhz range to effect 3 homes car and garage wireless. – James Cosgrove
