I can second that! As soon as I got the P3 working I realized that the annoying buzz I had noticed occasionally as I tuned 20 Meters was actually a nasty, wide 20db noise source every 50 Khz. It looked so bad on the P3 that it got me motivated to check it out.
After a bit of disconnecting things here in the house before I was going to start flipping fuses I disconnected my u-Verse modem and killed the noise. Then with the modem running again I started disconnecting connections - ethernet, data in/out and phone connection. By rerouting the phone line I was able to drop it about 10db. Still there but better and now I have a roadmap to work on as much of the remainder as I can. It's amazing how what seemed like a minor annoyance became an obvious problem when it shows up on the scope! BTW, has anyone noticed the very interesting waterfall pictograms created by the Chinese radar just below 40 meters?
