    I feel your pain. Either go to a balanced antenna, dipole or loop or move your shack to the garage (not really a bad thing) end-fed antennas are not so good IMHO.

    hello gents.
    I have question / issue that is very relevant to the grounding of my PC, but not relevant to ham family at all.

    My 144hz monitor is looking like the refresh rate is below 60hz, both on the desktop and while gaming. And the mouse movements are inconsistent.
    We have a discord group of people with the same issue, we did a lot of testing with involvement of professional equipment and electricians.
    The root cause seems to be in the grounding, and we have a success story of a guy who installed a proper 9ft copper rod under his yard and the issue went away.
    But the problem is that those of us who live in the apartments, usually cannot mess with the grid beyond the the counter.

    We are going into the area of "self contained power and signal reference system" used in the aircraft now.
    But since this is something that is plaguing the hams as well, I was hoping for an advanced advise here - is there any way to have a signal reference system built somehow at home, if proper grounding is not available?
    Open for any suggestions

    I'm not buying it.

    Me either. No way grounding would cause those.

    The only possible way an erratic mouse might be related to grounding is if static electricity were charging the mouse, but they are grounded through the computer three wire plug. If a wireless mouse, grounding wouldn’t help at all. A static reducing surface or spraying Static Guard or similar on the mousing surface would help.

    But I’ve never heard of a mouse static problem. Almost certainly the erratic problem is lint or dust in the optical path of the mouse.

    Maybe you could try one of these?

    Make sure to use the "Eartha Cables" that go with them.

    Maybe you could make one of your own? Get a plywood box, coil up some copper wire inside and fill it with dirt. You could probably even plant some herbs in it.

    Fresh or “broken in” cat litter?
