I know the basics behind EVP's, but not great detail.
It would seem it would be easy for a stray TV/radio signal (since so many are flying through the air) to show up in static on a recording?
Stray TV/Radio signals fly around in the air at certain frequencies. These frequencies are different for each radio station and tv station in a given reception area. Unless the recording device you are using to record is capable of picking up UHF or radio signals, it is unlikely that stray signals would be picked up in the air. Not only would the device have to be capable of receiving these stray signals, it would have to be capable of receiving the signals in the frequency range of the stray signal.
For small handheld recording devices or computer based recording devices, this is very unlikely. The strength of any stray signal would have to be enormous (such as being under a radio tower) or the signal generator would need to be extremely close, to be able to pick it up in the electronic circuits of a device without a receiver unit tuned to that frequency.
This interference issue is a major problem with ITC. TVs themselves are capable of picking up stray UHF signals in the air, so when you record ITC on television, it's very possible that a stray television image gets mixed in with the looping video recording.
