getting rid of two-way radio interference?


sometimes, when i play my rogue tempest magnum i will get a cb or two-way radio reception blasting through my speakers. it's blown a fuse once and it prevents me from actually listening to music. i know it only happens when 'the other guy' is on. short of tracking him down, is there anything i can do to eliminate this annoyance?

thanks in advance

Hmmm,

That's a pretty annoying problem. I know because years ago I had the same thing happen to me. Maybe using shielded interconnect cables and trying ferrite RFI collars on them would help a bit. There may be other things that can be done but I'm not an expert in this area.

My former neighber erected a huge radio antenna in his backyard and I used to get morse code through my speakers and also cb'ers passing by that would come through loud and clear on the stereo.

In the case of my neighbor, I contacted the FCC and there were some regulations that only allowed him to practice his hobby at times that didn't offend me. Perhaps a call to the FCC would be a good idea. I'm sure they would try to help.

Good luck with that; perhaps others will offer additional advice.
Not a whole lot you can do. Below is a link to some reading material. You could possibly filter him out if you can find him and the frequency he is transmitting at.

Some months back, there was an excellent article on dealing with EMI/RFI on the Audioholics site by Dan Banquer. It`s not easy but can be dealt with.
I'm a ham (WB5KKO) in addition to an audiophile. Most of the time when gear picks up a radio transmission it's the fault of the gear, not the transmitter. FCC regs say that as long as the transmitter is operating properly (and they usually are), then the elimination of interference is the responsibility of the user of the gear.

Most hifi gear is not really well shielded against stray RF. This would raise the price significantly.

The biggest point of entry for stray RF is the power line. If you're not using a good power conditioner consider having a tech install some bypass capacitors on the AC input of the Rogue and any source equipment feeding it.

Be sure all your interconnects are shielded, and take special care with your phono front end, if any. Due to the small voltages and high gain used, the phono system is particulary susceptible to RF pickup.

If your interference happens on all sources and is not affected by the volume control, then the Rogue itself is the culprit and you should focus your attention there.

It also can be the speaker cables and the speakers. I have seen instances where the amp is turned off and the Ham could still be heard faintly through the speakers.

Ghostrider45, why is it never the Ham operator's fault and always the audio system's? With all the commercial radio stations transmitters RF in the airways they do not come through audio systems like a Ham Operator's RF. Could you please explain?
