        I installed a 10M antenna 15 ft from my direct TV dish. TX at any power was wiping out the direct TV signal to receiver. One choke resolved the problem. Have tested it up to 100W output. I will have 2 or 3 on hand at all times in the shack.

            What mixture is it made of?
            The mixture gives the frequency range in which it works best. Without that info, you are wasting time and money.

            Comments about RadioShack Snap-Together Ferrite Choke Core:

            From another review: "And if you have a multi-thousand-watt commercial broadcast station located just down the street, you can't expect an inexpensive ferrite choke to eliminate interference from a source like that!"

            Well, maybe you can. There is a radio station broadcasting less than 1.5 miles from my house and it was loud and clear through my computer's speakers. Always had to power the speakers down if I wasn't listening music. When I was listening to music, the radio station was always in the background anyway.

            Read about these ferrite rings and decided it was cheap enough, so I bought three different sizes. It turns out I only needed to put them on one cable -- the thicker one coming out of the back of the sub-woofer box leading to the speakers.

            The one's intended for coax cable were just a little too large in diameter and would slide on the cable, so I put one of the smaller ones behind it securing it with a zip tie because it wouldn't snap shut (a little too narrow, in this case). I put four of them on as close to the back of the sub-woofer as possible, with the smaller ones holding the larger ones in place.

            No more 99.9 The Hawk broadcasts!

            Very happy with this solution.

                  This filter really works for eliminating RFI interference that stopped some of my power line X10 wall socket receivers from responding. I placed the filter on the AC power cord of the DVD recorder/HDD copier that was causing the problem even when turned off. Put the filter as close as possible to where the wire exits the case. Pass wire through the 17/64" ID hole in the filter and snap shut. Make a loop in the wire to hold filter in place. This filter should help eliminate RFI put out by most switching power supplies.

                    Comments about RadioShack Snap-Together Ferrite Choke Core:

                    These chokes work just fine for the purpose for which they are meant. If you're getting RF interference that is coming in via a wire or cable, these chokes will help cut it down or eliminate it. If the interference is coming from somewhere else, you can't expect these chokes to eliminate it. And if you have a multi-thousand-watt commercial broadcast station located just down the street, you can't expect an inexpensive ferrite choke to eliminate interference from a source like that!

                          The smaller choke core seems to do the trick. But what is the dimension of this choke core? will it fit a 12 AWG audio cable, or a PC power cable ? is this a package of 2 choke cores or single choke core?

                              Buzzing noise was reduced significantly due to T-Mobile Blackberry on desk with Boston Acoustic desktop speakers. Used 4 (2 packages) of 3.5mm 2 on each speaker wire and one 17/64" on A/C line into computer - Apple G4 Laptop.

                              Will probably get another set of 3.5mm to see if they remove the small amount that still bleeds through once-in-a-while.

                              Even with that many products purchased, it was well worth the investment and convenient to try/return if they didn't work. I recommend trying them, moving their locations on the wire also helps - one close to the speaker, one further away and such.

                              While I was awaiting the arival of high-end power cables and a line noise harvester I thought I would try a couple of chokes on my existing power cables. I probably got lucky with where I placed them but they enhanced the vocals on some music tracks. Basically, they helped warm up and take the edge off the vocals on some music tracks that have that dry, 'tinny' sound that CD's have. I know some folks don't see any results, and some get unfavorable results. I suppose that's due to the equipment, location on the cords and a lot of other factors. In my case, it was a good low priced audio tweak. For [$]... it's worth trying.
