Ever wonder about those strange noises you hear in your receiver? Is QRN causing you to lose QSO's? Well, Ken, VE3HLS, has created a WEB PAGE to help you track down that offending noise. He has files on this site which he has identified that will help you track down what is causing the noise. The files are MP3 audio files and you can look at the waveform of the noise to see what it looks like on an oscilloscope.
