Greetings all,

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 ?
