  • radio buzz

    I reconditioned 4 fluorescent light fixtures with new electronic ballast and T-5 bulbs for my pole barn
    and now my radio won't pick up any stations I tried to run a wire outside with a homemade antenna
    still just a buzz anything I can do? Ken

      the only easy way out of this is to make a Faraday cage around the lights with brass screen (grounded of course)
      or use incandescent lights
      shooting the s*** is a lot more fun when you use hollow points (much more splatter)

        T-8's with electronic ballasts generally do not cause radio interference, if that's what you are using. Are the lights and the receptacle you are plugging the radio into on the same circuit?

          no they are on separate circuits.

            If everything is properly grounded, you have to start a process of elimination. With the radio on, pull the bulbs from one fixture, if no difference, replace and move to the next one, and so on, until you eliminate the radio interference. Then try new tubes or replace the ballast. I hope you didn't use crap from Home Depot, or you may be repeating the whole exercise.

              are these plug in fixtures or hard-wired?

                Thanks guys for the help I will try to eliminate one light at a time, they are hard wired and ballast are new from lighting supplier. When lights are off radio works great I have another fluorescent (4 bulb)
                over the workbench with regular ballast does not cause interference and is about the same distance and yes tried different radios Ken

                  I finally got around to the light fixtures, I tried to eliminate one fixture at a time as per killivolt but didn't solve the problem I don't know what to try next except maybe going back to regular
                  ballast and t-12 bulbs, got over a hundred dollars in these four fixtures. thanks for all the help. PS I also tried a strip that had a rfi and emi in it no good. ken

                    If possible return the ballasts that are noisy..they should be quiet!
                    Likely they are big box store china junk!
                    Look for the FCC, CE, and UL listing

                    The electronic ballast can often act like the noisy switching power supplies
                    If you have noise simply dry a different brand or unit!

                    These can generate so much grunge into the power line and over the air that they are
                    simply trash out of the box! You may never be able to externally filter the noise out!

                    Have you tried reinstalling the original ballast to see if the noise goes away?
                    If the lights work with the old ballast why replace them?

                    You may also want to try different lamps as they too can generate noise!

                    You never indicated if the radio interference was gone with the lights turned off....

                    Another noise generator are tool battery chargers. The 3rd, 4th, and 5th generation Ridgid
                    battery chargers are quiet! I know of some black and Decker, Skill and really old DeWalt chargers
                    that are terribly noisy!

                      is the radio grounded?

                      we had a projector at church that had lines going through it, and finally discovered that the ground had interference on it (conduit) from the dimmers in the building, when the ground isolator was used, (a special device for some electronics that keep the ground in tact but some how isolates it), but one can test it with a three to two prong adaptor,

                      I have a cheap radio in my meat cutting room and turning/rotation it and location, it makes a big difference on how the radio is orientated to the direction of the station, (or the lights),
                      to one way all you get is buzz and the other the radio is usable, (this is on AM),

                        radio works great with lights off. Would it hurt to try t-12s in the fixture to see if its the bulbs? I switched to electronic ballast because I heard they start
                        better in the cold like high output.

                          the documentation you got with the ballast should tell you what lamps are compatible with it.
