My luck it could be a DIY install as there are are not many panels involved. I still need to check it further with a SA or at least a portable receiver, as admittedly, it might not be related given the number of new houses popping up in my neighborhood.
Perhaps 40 acres in a remote Wyoming location would be the better radio listening solution for me. o.0
Dropped my 31' vertical back down to the previous ground mount location. Same ~2.5:1 hybrid dual-core unun at the feedpoint. Just a ground rod without radials for now as it got dark outside. RG-11 back to the house.
The hybrid unun as designed was intended for a wideband end-fed vertical antenna with minimal RF grounding anyway. It seems to be doing okay so I might forget the radial field for awhile.
The noise profile already looks better IMO, though it is nighttime so I suppose the real check will be tomorrow during the day.
Skimmed multiple bands. I have WWV(B) time signals on 60, 2500, 5000, 10000, 15000, 20000, and 25000 at ~1:30z using the 31' vertical. :)
KiwiSDR 2 at default dB calibrations. 31' vertical fed with a dual-core hybrid unun against a ground rod. -10dB shelf filter under 10MHz.
Acopian VA5H3200 5vDC 32A regulated linear power supply. Straight to the plug on each side. No extra mains filtering, ferrites, etc.
Only 15dB SNR during mid-day as I post this message, versus my Kiwi often reporting in the mid-30s at night even on its previous switching power supply. A loop with the HFDY LZ1AQ-based preamp I have on order might improve the daytime number.
I am using an old router running as a station bridge for testing the 5v PSU. It is on a 12v linear regulated power supply, but the router itself could be contributing to a little longwave noise. I did not bother with ferrites on the LAN cable, either.

(click to enlarge)Here is that "wonderful" 15dB SNR during the day. This is with noise blanking and tweaking the waterfall to better hide some of the noise. I have seen much worse, but yeah, it is not great IMHO.
(click to enlarge)Again I am hoping the situation improves with a loop actually having moderate decent nulls. Also I still need to check RFI near that house with the solar install.
BTW, noise blanking is one area where I find SDRSharp excels with the Airspy HF+D. Really can comes in handy when needed.
Need to find one of my radial plates, but anyway, there are four ~31' ground radials now under the 31' vertical. It is start.
