Paradigm Servo 15 picking up AM radio station

Thanks for all of your responses. I finally bit the bullet and took the sub in for service to get it checked out, and it turned out I had a loose ground wire connection inside the unit. I bought the sub here in AG, so it probably got jarred loose in shipping, but who knows? This has fixed the problem. Turned out to be a $90 fix, so no big deal.

I think you'll find that it's the interconnect cable and not the processor. I had the same problem. It was the cable...

Thanks for the responses guys. I think it is coming from the processor. The power cord that I am using on the processor is not shielded, so I may try removing that part of the equation by replacing it with a shielded PC and see what happens. I did try just disconnecting the sub interconnect cable, and it did go away, so I am thinking it has something to do with the processor (which has a tuner built into it by the way). The sub interconnect cable is a Monster cable that does have shielding (what kind of shielding I am not sure). I will also try repositioning cables as well and see what happens.

It takes very little to pick up a radio signal. The simplest, easist way to do it is with a wire. So the first thing I would check would be the power cord and the interconnects. If it is one of those wires, you might be able to eliminate it simply by moving the wires a few inches one way or the other, or even by altering the orientation or shape of the wire lying on the floor.

So does it make an AM jock sound like an FM jock? Sorry. I have never heard of this but here are a few scenerios. If you have Directv or dish sometimes that can feed it to a household. Mine was in my cordeless phone. Possibly if you have Sat TV you might try disconnecting the power cord, coax,and phone connection from the DSS reciever and see if the "little voices in your sub" go away. If that is the case it is probably either feeding back through the a/c if they are plugged into the same circuit. If not then it is through the interconnect. If this proves to be the case
there is a filter that plugs into the telephone connection
and filters out the RFI. If not I am not sure what else I would look at, a sub is a crossover, amp and speaker, can't imagine how it could become a tuner. One other thought, if haven't tried disconnecting the IC and observing the loss of the AM sound, try that it. If so it may be in your processor, especially if it a receiver.
