I don't know if this will help, but if you know anyone in engineering
at a radio or TV station you might ask if they have any UPS's they
are going to get rid of (trash). I have two 1500 VA rack mount UPS
sine wave units that a local station was going to trash. The chief
told me that when the batteries get old they simply replace the
entire unit. Mine have been running my two DATUM GPSA units for
about 8 years and I've only had to replace the batteries twice; once
when I got the units and one other time about two years ago. They're
still going strong. They're pretty close to my HF radio and I have
not experienced any RFI from them.

Hi,
I have decided I'd like to get a UPS to put on the rack containing my
Thunderbolt, the laptop that runs Lady Heather, and frequency counter.
Has anyone had bad experience noise wise with the APC brand units
like are available on Amazon and at Staples? I'd like to get one that
doesn't generate lots of RFI. Thank you.
