Wayne When i put this new shack up i posted a lot of pictures but never posted the one with the earthing system i am using. Have you been round here at night as you have the exact same system as i have installed lol. Same noise as well here on top and the 80m bands.

Nothing. All RF grounding done at the antenna where it should be so you're not getting common mode RFI on the coax which increases noise.

All my antennas are also grounded. Plus i have lightening arrestors fitted and grounded. For what it cost to do it when putting the new shack together. 2 rods and what was left of the 7 or 8mm ? cable i ran the power to the shack twin and earth all joined for earthing

I am doing nothing on 80m and 160m bar a little listening. The G90 matches up the 10m though 40m fan dipole for the two lower bands, but the effective power that would radiate on the bands I am guessing would be so small because of the losses I haven't bothered to try.
Only grounding I have in place is like described on THIS PAGE. I have had issues with noise in the past, but nothing major for a long time. Lower bands are actually quieter for me than the higher ones. All are usually between 0 and 3 on the S meter unless there's a storm, which I don't think is bad at all for an indoor antenna system in housing estate. 12m up though to 70cm I do get some odd rhythmic pulsing and a few odd narrow bandwidth spikes here and there since the neighbours installed a fortress like security system, but can live with that as it doesn't blanket wipe out everything.
If shack was on ground floor, antennas were outside, and I was using more power, then I would look to do something more for grounding. But happy as is for now.
