I just bought a APC Back UPS Model BR1500 about 2 months ago. I realized
recently that it is generating hash on the lower portion of 80 meters
that gives me a S9+ noise level. I use coax in the shack to all my
antennas. The antenna is located about 60 feet away from the shack. Has
anyone else experienced inverter hash from their UPS ??? Did you resolve
the problem ? Did ferrites on the line cords help ?
