Speakers
 

My logiech speakers pick up and play WDUQ a jazz band station out of Pittsburgh. The problem is that they play this station constantly, even when i am playing other music. Does anyone have any idea I can stop them froming picking up jazz and showtoones show i can hear my own jazz and showtunes?

I don't know how to help, but I just wanna say that when my old PC Logitech's started doing that, it scared the shit outta me one night. :) I couldn't find where the radio was coming from...the PC speakers were at 0 volume and I had no radios in my room. :) Good luck in fixing it, anyway!

I believe it has to do with your sound card in your computer not being grounded completely, not with your speakers. Maybe check to see if it is in contact with your case at all?

haha yeah i use to have a similar problem. I could hear truckers talking on there CB's :). I just got different speakers and the problem went away.

OK, so the speakers are picking up radio stations? Try moving the speakers (and especially the cords) around. I think one of the cords may be acting as an antennae. Thats all I can think of anyways.

Q: I have some cyber-acoustic speakers with a subwoofer, and for some reason they pick up a radio station. Is there any way to stop that?

A: I'm sorry to say that shoddy speaker wires may be the cause of your signal interference. To cut costs, speaker companies often use speaker wire with inadequate shielding and poor filtering, which offer little protection against radio-frequency waves such as those coming from a stereo, ham radio, police scanner, taxi cab, and the like.

Five steps to better sound

1. If you're lucky, your computer speaker wires are acting as an antenna and your confused speakers are amplifying the wrong signal. It's annoying, but relatively easy to fix. First, try shortening your speaker wires as much as possible. Move the speaker wires around; sometimes they'll pick up noise in one place, but not in another. You should also ensure that you've connected your speakers properly, that the cable doesn't have any exposed wire, and that you securely attach any phono or RCA jacks.

2. If your speakers aren't hard-wired, try upgrading the cables that connect to them to a set of well-shielded cable. If they are hard-wired, try picking up some ferrite beads from your local Radio Shack. These beads are designed to filter out radio signals across many frequencies. A pack of ferrite beads costs about five dollars, and we've found many people who have had as much success with these as those who started off with high-quality speaker cables.

3. If your speakers have a three-pronged plug that you stick into a wall outlet, one of those prongs is the ground. Make sure you use it. The ground should help to prevent interference, at least if you have a clean ground line in your building.

4. Finally, if you're into spending money, you can try picking up a power strip that promises to suppress electromagnetic interference (EMI) and radio frequency radiation (RF). These strips aren't cheap and we recommend you try all the other tricks first.

5. If you hear an odd humming noise, chances are you can fix it with time. That humming noise is usually a ground loop. We found an outstanding article that lists sources of lots of unwanted noise in your system and shows you how to root it out of your video and audio systems. Just be prepared to spend some time tracing the source of that noise.

I'm just fascinated that this happens! I've never heard of or seen this before, but I'd love to see it myself, just for the hell of it

on my old Cambridge Soundworks speakers, I picked up telephone calls from across the street......I had the volume all the way down, and the speakers turned OFF.......and it still came through......power was indeed going into the speakers(i.e. plugged into the wall), but they were definitely turned off!

scared the hell outta me! it didn't happen often so I didn't care
