Recently moved and setting up my antennas and equipment. At this point looking at the HF bands. I have major RFI from a shop fairly close by. The noise is coming from their T-5 fluorescence lighting fixtures. When they are off my noise is down about S-1. Turn the lights on and the S meter immediately jumps to S-8 & 9. Tried disconnecting the lights from the main power system and running them off of an inverter in my PU. Everything totally isolated. No help, so it appears the RFI is being broad-casted rather than being carried along the power lines. Now what? ? ? Looking for ideas suggestions, and what has worked for others. Thank You
