My amps are radios, how can I stop this?

Post by Pepe Silvia » Mon Jun 25, 2018 5:59 pm

I live very close to a large field of powerful radio antennas and I have a lot of interference on both my amps. I'm assuming my guitar acts as an antenna. Anything I can do to quiet this noise?

You could try knocking down the antennas.

You could also try going to radio shack and buying some of those thingies. You know the kind, they put them on all kinds of cables to reject noise. They look like weird cylinders a lot of the time. They're magnetic. I fixed my monitors that were picking up the radio that way.

Ferrite ring EMI/RFI filters you mean, stick em on your power chords and get the best shielded audio cables you can find, should do the trick.
Logic gates based on billiard-ball computer designs have also been made to operate using live soldier crabs of the species Mictyris guinotae in place of the billiard balls.

Thanks

I'll give those a shot. My Bullet Cable, a $50 cable, has this issue

The audio cable is only a small amount of the source, got to clean up your power as well, those cables are not shielded, the ferrite RFI/EMI suppressors generally take care of that. Cost of a cable tells little about shielding, the shield forms a capacitor with the conductor which forms a filter with the impedance of the source/destination, better the shield the more capacitance, the more filtering, sometimes they skimp on shield to lower capacitance. It is a trade off and there is no perfect solution when dealing with passive guitar pickups, using the shortest possible cable with the best shielding between guitar and amp/fx/etc will often help at home and the studio and not color the audio.

I have a fondness for antenna farms, ours is on the hill and it was always the first view of home when coming back from a trip. I often sit on the beach at night watching the lights blink and work out rhythms to their out of sync blinking, can find some good patterns in those two dozen or so blinking lights.

For the sake of completeness, is there anything these should't be on? I have good instrument cable, but the electrics in my home are haunted. Ferrit rings on the power supplies seems like a sensible ideal, what about speaker cables between head and cabs?

Ferrite ring on power supply to pedal board?

I think I'm maybe going to go mad and put ferrite rings on everything I have here..... which end of the cat should it go on.?....

Put them on the AC mains cable of things which are having issues with RFI and/or EMI, you will be throwing away money using them elsewhere, use good quality cables everywhere else and always use the shortest practical length and you will likely be fine on the EMI/RFI front.

The issue eurotrashed is having is due to the fact his house has a metric mile (same as a normal mile, just more precise because there is a decimal point followed by lots of numbers) of wire in the walls acting like an antenna, that is a good sized antenna with a fair amount of power when located near a good RF source like an antenna farm, anything you plug into that antenna is going to see the signal it picks up. Your issue maybe fixed by the ferrites, may not, your description is vague and tells nothing of the situation. Trying to solve problems without first identifying what that problem actually is and its cause, tends to be a good way to waste time and money and often causes more problems down the line to throw more time and money at.

if this happen suddenly ? before not ?
first it could be an amp trouble ,tube used,capacitor ect ....
i remember before my classic 50 short and burn du to too much used tube i heard german radio in ,and at this time i live maybe 800 km far from Germany
when it came back from the tech after the repair i have no more trouble

Both of my amps do it and I recently moved into this house.

I am going to try some fertile rings. Thanks all

Will any of the ferrite rings work or do I need magnets that are a certain strength?

The bigger, the stronger. The square kind for inside need a certain amount of slack in the line so you can wrap it in there, or at least the ones I used did. I put them on the power line running from the amp to the driver or whatever inside the monitor. As far as I know, the kind you clip around a cable just need to be a diameter match, and again the bigger the stronger.

You could also try a power conditioner, if you aren't using one already.
