Dear OMs and YLs,PV Panel noise does not necessarily go away at night. I have an installation at a neighbours and it generates noise 24 hours a day. Filters and ferrites have largely solved the problem but it was an expensive enough effort. Good luck, we are all in for it.I paid as my neighbour has always been good and they are valued.73 Doug EI2CNSent from my Galaxy -------- Original message --------From: Lyn Norstad <[email protected]> Date: 19/04/2022 14:38 (GMT+00:00) To: 'Brian Hunt' <[email protected]>, [email protected] Subject: Re: [Elecraft] Interference on 17M 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!73Lyn, WØLEN-----Original Message-----From: [email protected] [mailto:[email protected]] On Behalf Of Brian HuntSent: Monday, April 18, 2022 7:34 PMTo: [email protected]: Re: [Elecraft] Interference on 17MPotentially 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. 73,Brian, K0DTJ> On Apr 18, 2022, at 07:30, Ron Bell via Elecraft <[email protected]> wrote:> > Does anyone know the source of interference in 17M, starts at 18.138, peaks> 18.147 and second peak at 18.158, sounds like very rapid buzz or popping> sound?
