EVP anyone?

When I worked as a theatre technician many moons ago, we used a Clearcom
system with Bayer headsets. This was in Montreal. If the weather conditions were right (don't ask me to remember what they were)
we could easily pick up the local AM Radio-Canada broadcast of the Canadiens game from the Montreal Forum about a kilometere away.
This system was not wireless.

One thing that gets me about EVP, is that every website concerning EVP, encourages using cheap handheld recorders. They say that the higher priced, more sophisticated gear filters out EVP frequencies. However they never claim to know which and what kind of frequencies carry EVP. I've always wanted to use pro audio gear, condensor mics, soundboards, multitrack recorders, laptops, etc. To do a cross examination with the handheld recorders. I don't think that gear would pick up any of the EVPs ghost hunters are claiming comes from their handheld recorders. As someone who enjoys sound mixing/engineering, EVP interests me in a way, though I don't believe in anything paranormal, I think EVP could easily be debunked. I think that the handheld recorders, are picking up internal noise, or its the operator making by jostling the recorder or rustling the mic, or it is noise they are themselves making that they can't recalling making.

Or they're picking up the radio. If I plug my bass into my amp with a cheap cord with crappy (or no) shielding, radio stations will come in and out.

Any unshielded or poorly shielded piece of wire can act like a radio antenna.

Reminds me of when I was a kid and my friends and I would argue over whether or not the TV was picking up alien signals because there was a very strange looking "background image" behind the image on the TV (best way I know how to explain it). I asked my dad about it and he said, "it's probably just a crummy TV, buddy. I'd guess you're picking up some other station." Needless to say, he was right.

I believe the correct phrase for this is called Signal Bleed-over; it's when the signal bleeds over into other broadcast frequencies either due to problems with the transmitter or (more likely) the receiver can't completely filter out a strong neighboring signal.

So can audio tape recorder heads and phono cartridges.

Short, uneducated answer - you've got an amplifier (the amp) and an antenna (the instrument cord or even the power cord). That makes a radio. It's not a useful radio because you can't tune it, but it's still a radio.
