[Elecraft] P3 Display Anomaly

[Jim Sheldon]

Disconnect your antenna, set the REF LVL on the P3 so you can see the background noise at the base of the display and watch it for a while.  If you no longer see it, it isn't in the K3/P3 anywhere and is external to the radio.

I have several "sweepers" that come through from time to time.  One is somewhere in the neighborhood and the other is coming from a bad TV cable line amplifier on the pole outside my house.  I'm having a heck of a time getting the cable company that it's their problem and they are liable for fixing it.  I have gotten the local "fox hunt" group out and they confirm my findings and we know exactly which amp it is.  I have spectrum pix of it using the image capture feature of the P3 with dates, times and frequencies.  I filed a formal complaint with the FCC and sent them copies of all correspondence with the cable company, my spectrum analysis pictures and notarized affidavits from the fox hunt guys with their direction finding results.  Hopefully that will get the same results I got with the power company.  Had to file a formal complaint with the FCC on that one too, but now, they are all sweetness and light and whenever I call 'em they jump on the line noise problems as quick as they can free up a crew to clean/fix insulators in the neighborhood.
