I have been chasing this noise in my urban neighborhood for several years now. It usually visits during the daylight hours and stays for several hours. It has a rhythm and is across all frequencies and bands. I have pulled the big switch in my house and the noise is still with me (listening on battery powered rigs). Neighbors on all sides of my city sized lot have swimming pools and my first suspicion is noise generated by circulation pumps.
Here are two recordings (on a K3 of coarse). Why not ask the most discriminating radio fans in the world their opinions on the source? http://www.flickr.com/photos/ak5x/4279625626/in/photostream/ http://www.flickr.com/photos/ak5x/4279577818/in/photostream/ Bill Hammond-AK5X [email protected] [email protected] [email protected] K3 #69 K2/100 #4637 K1 #2033 KX1 #1023 T1 ______________________________________________________________ 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
