Hardware & Technical Ok, this is getting quite annoying.

I live VERY close to a nearby air-force base. My speakers are Bose Companion 20 multimedia speakers plugged into the "line out" jack at the back of my computer instead of the front headphone jacks.

For some reason, air-force messages, in fact I can hear radio-static voices interfering into my speakers and sometimes morse codes are heard as well. When they play, I turn my speakers off but I can still hear them playing two seconds after I turn the speakers off and the noise stops playing. My motherboard is an Asus ROG maximus vi hero and my operating system is Windows 7 home premium.

Thanks if anyone can help.

I would avoid making this information public as the transmitters, will not be impressed that this is happening. At the same time, something is giving you feed-back and if it were myself. I would get the house swept for bugs etc.

You're picking up stray signals from their transmission. It's caused by the transmitters being too powerful.

It's an unusual problem these days, mainly because most transmissions are digital, much lower power and military are generally encoded. I can only assume the Canadian Air Force likes using ancient equipment!

The way to deal with it is shielding your speaker cables. Also any others. You need to wrap them in foil and ground the foil.

I know in many countries, the ground connection for the Mains is often inadequate or absent. The US has a terrible reputation for that. Also if you live in a rural area or in an old property then your wiring may simply be old.

If you suspect yours then you might think of making a ground connection for yourself.

A long copper rod or pipe, pushed into the earth should do the trick. But it needs to be quite long. Then attach a 6mm length of cable to that and the other end to your computer case. That should be good for up to 50 metres or so.

There was a time when most people got pretty satisfactory results from a cold water pipe. This has problems for two reasons. Firstly, many modern waters supplies are fed by plastic. Secondly, most water companies don't like it for obvious reasons and in some areas it's actually illegal.

Your foil shielding should be attached to your case with short lengths of flexible wire, about 1mm. Don't make these too thin. You need a really good connection.

Your PC/house wiring is acting as an antenna.

You'll need to either use shielded cables, or wrap your amplifier in tin foil.

I say with respect, please do not wrap your equipment itself in foil. Amps produce a lot of heat and that needs to be disapated. It is likely your amp will be in a metal case. If it isn't then it's unlikely to be a source of the problems. Manufacturers of that sort of equipment generally provide more than adequate earthing. Bose is a very reputable manufacturer.
