I don't recall the model number, but I flat blew up a CyberPower UPS of
similar rating a couple of years ago. I never heard any RFI from it but
the first time I fired up the 500W amplifier on 12 meters it gave a
"crack" sound and spewed a small shower of sparks from somewhere inside.
It never worked again. I replaced it with an APC model that's worked
fine ever since.

I wanted to let folks know that I've found that the CyberPower 1400VA

I have twin strong signals space 1 kHz apart, occurring every 35 kHz
on the bottom end of 6M. They also show up on 160M.
Back to Costco it goes.
