Fred, I assume that you've confirmed that it is being picked up by your antenna by removing it and connecting a dummy load and see that the noise is gone.
IMX, plasma TV's have a very w-i-d-e noise signature that sounds like someone connected their HF noise generator to an amp and antenna. Unless you are there when they turn it on, it sounds like ordinary band noise but much higher in level, depending upon how close you are. 73 Ron AC7AC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Fred Jensen Sent: Monday, April 29, 2013 7:17 PM To: Elecraft Reflector Subject: [Elecraft] P3 Noise signature I usually check into the No Cal Net on 3533 each night. I've begun to get predictable noise with a unique signature on the P3 WF. It's a series of bands, the first [around 3545] is the widest, they get narrower up from that and the separation seems to be about 40 KHz. The higher components get narrower but aren't any weaker. Occasionally I've see it come on to an otherwise quiet band, and all the "bands" on the WF drift some before stabilizing. I have a screen shot from the P3 I'll send, anyone have any idea what this is? I never see it in the daytime on any band, just in the evening, which is suspicious ... plasma TV? If it's my neighbor Casey, I'll just need to live with it, we don't do battle with our neighbors. Besides, Sampson, their cat, gets along with ours and shares his food. 73, Fred K6DGW - Northern California Contest Club - CU in the 2013 Cal QSO Party 5-6 Oct 2013 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
