[Elecraft] Interference on 17M

[Lyn Norstad]

In solar (PV) systems, Inverters, Charge Controllers and associated cabling are the prime suspects.  There is a lot of info on the internet, and some of it is pretty good.

Shielding can be effective, but the real problem is that the FCC has seen fit to exempt solar systems from most Part 15 requirements.

Good luck!

Potentially a solar panel. Any new installations nearby?  Does it go away after sunset?

I have an S9 noise signal on about 14036 with spurs on either side coming from a new solar installation about 200 yards away. Broad but very stable. Makes that section of the band tough to use. I think it’s Solar Edge but haven’t confirmed it.  QTH is Northern California.
