That's a tough one. A radio signal could be coming into your system through a number of ways, but to be transmitted out your speakers it would most likely be coming from a microphone connection or directly from the preamp or output amplifier on your sound card. When the radio transmission starts try unplugging the microphone out of the back of your computer soundcard.
Obviously there is a circuit on an input or output that is naturally tuned to the specific frequency, I'm sure by accident. If you have powered speakers this could also be the culprit. Try a different set of speakers.
Most components are properly shielded and don't have these types of problems, but I have seen it happen in many pro audio systems. Start with the easiest components, If all else fails you might try a new soundcard. Hope that helps Shawn.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
