Hi there,

Since a few weeks I've been plagued with this pulsating type
interference. I can receive the it from 12 MHz up to into the high VHF
range. So far I've found one very wide peak around 19-20 MHz (S9). I can
even see it on TV channel two (antenna, no cable) where it appears as 4
or 5 squiggly lines. Here's a sound sample:


And the image of the recording made by Audacity can be found at:


The recording is made with the receiver on 28.4 MHz USB. 

Any suggestions are greatly appreciated.
