Ok….I installed a no 10 wire between power supply and Omni 7….that seems(?) to
have cured the problem.
No chopped the 3rd pin ground….I got everything in the shack tied to a
industrial grade sine wave ups running on a dedicated 20 amp circuit.
speaker is on the right of the rig….also have a little astron ss30 and a huge
astron 50m linear power supply that I used to use for entire station.
No rf hash for any of the laptop chargers so far…
