Another 380 MHz Trunked System and Garage Doors

Another story has  emerged about people having trouble with their garage door remote controls likely due to interference from a government 380 MHz trunked radio system:

These systems have been blamed in other areas for causing issues, but since the garage door openers are FCC Part 15 devices, they have to accept any interference from licensed users. The door opener remotes are often built with poor selectivity and get de-sensed from the legitimate radio systems nearby.
