[RFI] Motor starting and UPS

The power to my computer is via a UPS.  My SDR is powered from the computer.

When one of the water circulation pumps for my heating systems starts 
(an old B&G), the voltage dips so much that it is apparent in the 
waterfall and a drop/loss of audio.

I've tried switching legs (red v black) but that didn't help. Let's 
ignore the idea that the service is too small.

I thought that UPS might "protect" against such dips in the voltage and 
am (obviously) surprised that it does not.

Whadaya think?
