I'm a 160, 80, 40 meter amateur radio operator including MARS, as well a LF, MF Dx'er, even some SW on 120, 90 60 meters, so noise was a big problem for me here in the swamps of central Florida. I tried a variety of solutions including loops, flags, beverages and phasing devices like the MFJ-1025/1026, all with varying degrees of success. Next I began studying the local power grid installation and it's lack of maintenance and came to realize that most of my noise came from arcing across lightning arrestors damaged by lightning strikes. This was verified by a portable radio QRN search by me. Then it was off to communicate the QRN problem with the intransigent local power company, then the ARRL and even the FCC, a very slow process laborious process. Anyway to make a long story short, the removal of the ground wire lead from the lightning arrestors on the power poles became the temporary solution for me, followed by replacement of the lightning arrestors. My QRN went from +20 over S9 to S0-1 on 160.
