Title: RFI noise on 80m and 40m Post by: ka4koe on August 21, 2013, 02:56:46 PM Can anyone help me identify this noise source? I hear it, primarily during the day, from 3.5 to at least 7.3 Mhz. I recorded this last night around 10 PM EDT on 40m, but the signal strength of the noise was down. Sometimes this interference goes away completely. A regular noise blanker can do nothing with it.

It sounds eerily like the old Russian Woodpecker. http://snd.sc/183Sjty Philip |
