I have an inexpensive CyberPower 825 AVR UPS, The UPS does the job of
keeping my computer and time-nuts gear running, but it causes an annoying
amount of RFI in the AM broadcast band. The noise is radiated from the
circuit that feeds the UPS. I found that plugging the UPS into a Belkin
outlet strip, which presumably includes some line filtering,reduced the
interference significantly.
