They are operating in a band assigned to & used heavily by the military.
Anyone here really surprised to hear about this issue coming up... again? Anyone? Anyone? Bueller? Bueller?
Problem is try explaining that to a generally uneducated (RF wise) public who for the most part are becoming anti-military thanks to the current political atmosphere. Joe Public thinks when he plunks down his Visa card for a Genie garage door opener, he has the backing of the law to protect his investment and no one or nothing should interfere with HIS right to do what HE wants to. When outside signals interfere with his new garage door opener, he goes beserk and looks for someone to blame it on, or worse yet, to sue to make some bucks off of!!!!
Bad thing is .... RF hasn't read the law or anything else. It obeys the laws of physics and electronics.
That aint nuttin. Local infamous 11m operator brags about getting investigated by FCC & Military personnel for opening bay doors here at Wright Patt AFB back in the late 70's. (My neighbor that makes 10m useless)
I was the "go to" guy for RFI problems while I was stationed at Fort Hood in the late 1970's, and one of the complainants demanded I stop CB'ers from interfering with his test equipment.
