It's the damndest thing... I go to record through my Rebel 20 half stack the other day and when I cranked the gain, I heard a radio station playing in through the amp. This is not a joke. WHERE is it coming from?  I don't live near a radio station. |

You don't have to. AM radio is actually beamed straight up from the ground. AM radio stations actually have antennas either in the ground, or laid out above it. They beam upwards and bounce off the ionosphere and come back down. that's why going under bridges cuts off the signal, or when it's rainy/very cloudy, the signal is weaker or interrupted easily by lightning.
Because of such, AM radio can travel either very long or very short distances depending on weather.
AM can be rectified down into the audio spectrum by various means. Usually an antenna made from a guitar cable and a diode junction made by slightly tarnished contacts can create enough of a "radio" that you hear it.

I once had a Hammond M3 that, when played through the Leslie147, would consistently pick up a Canadian radio station. I'm in Connecticut,USA.

cowboy, if you relocate you amp or yourself and the guitar, you'll probably solve the issue..

I borrowed my wife's black face deluxe that Paul Rivera modded for her, and midway thru the gig, someone from the audience pointed out that it had smoke coming out every 1/4" hole on the front panel. Of course I turned it off immediately. And then, after getting it back to the studio it worked fine for years and years.... As for radio stations, it's usually in the guitar or the guitar cable, but sometimes the amp. Like someone said earlier, try turning the amp or guitarist 90 degrees to see if there's a change. |

Unplug guitar, rf gone? Fix instrument or cable.
Unplug guitar, rf still there? Install a ferrite bead in the amp's front end. You can also buy "snap-on" ferrite bead cores that snap over the guitar cables, place them about 2" from the input jack.

I have this problem occasionally when guitar players sit in the Control Room with their amps and I run a long cable between the amp and the cabinet. I never have the problem with a short cable run from the guitar to the amp and the amp to the cabinet.

Yep, it's a long cable run. Bet that's it.
