Tom, Attach the unconverted stream recording to an e-mail to me off list. I can convert it into an mp3, then put it where others can get it, but that won't happen until late this afternoon or tonight, as I am about to be away from the computer for awhile. My first guess is it is either a video leak in somebody's cable feed, or a switching power supply or battery charger.

Over the past 2 weeks, I have experienced an interesting interference problem on 10 meters. It is only on 10 meters, but it exists throughout the band. The best way I can describe it is that it sounds like a helicopter spinning its propellers. Ok, don't laugh, that's the best I can do! (grin) I wish I could send the list a recording of the interference, so folks could help me determine its source, but I obviously can't attach a wave file or anything like that to a list-serv e-mail. If anyone has any thoughts as to how I might send the interference recording to the list, let me know. I have recorded the interference on my V R Stream, and need to use the Companion software now to convert it from a 3 G P format to a wave file. 73 from Tom Behler: KB8TYJ
