After 33 years of dealing with TV and radio interferences of all sorts and many times having to go search for them by walking in the streets with an antena, a field strength meter and a portable TV set, this doesn't really come as a surprise to me.
It kinda reminds me of a case I had in a zone of difficult TV reception where one day everybody stopped receiving the Ch. 3 of the VHF I Band due to an interference. After checking that none of the antennas of the area was causing it, we decided to shut down the power of all the apartments that were being affected one by one until we found the cause. It turned out to be a Grundig VCR's power supply!
At first we thought it was because the VCR was connected to the antenna but no, all it took to completely block the picture with interferences was being connected to the mains anywhere inside the apartment!
A few years later the same thing happened with a brand new Grundig satellite receiver but that time, through our supplier, we managed to bring an engineer from Grundig Portugal here to witness the problem
in loco.
Some years ago AV transmitters (AVT) started being interfered by microwave ovens, so much that the AVT manufacturers had to change their equipments' frequency from 2.4GHz to 5.8GHz. Otoh, the 2.4GHz AVT's Ch. 1 (they have 4 channels to choose from) interferes with WiFi.
It's very common to hear people say that they can receive police or fire department communications on their "made-who-knows-where-and-apparently-with-on-paper-only-interference-compliances" baby monitoring devices.
Recently I discovered that even 4G can interfere with the LNB's for satellite reception, so much that manufacturers started making LNBs with 4G filters. And 4G is broadcasting between 800 and 900MHz, while Ku band satellite services broadcast between 10.6GHz and 12.75GHz!
WAFM, that's what I say.
