I don't believe so, but I will check again. I was inside the house with the
power off for about 30 minutes, and do not recall a UPS alarm, not have I
seen one in their computer room.

Are there any UPS(s) in the house powering devices that remains on even
though the main breaker is opened?

>From about 100 - 130 degree heading, I have a nondescript noise level
increase from less than S1 and peaking out about S5 - S6, that is driving
nuts. It happens to be across a neighbor's house, and I seem to be able to
hear the noise in my portable receiver.
It is broadband, generally from 10-21 Mhz, peaking out about 18 Mhz. I
hear it distinctly with the portable (TH-F6 & 18 Mhz whip) placed near the
meter entrance and ground of his house (mine is very quiet in comparison).
**The noise is present even when all breakers and main are shut off (great
neighbor).** I can also hear the noise to a lesser extent next to the
pole that services his house. Noise blanker has no effect.
It is 24/7, constant signal level, rain or shine.
The service meter is a smart unit by Landis + Gyr, "-855 type ALF Form 2S,
CL200". I have one just like it at my house, but is RF quiet.
Has anyone experienced this kind of problem with these units?
There are other possibilities down the neighborhood (which do need
attention), but none really sound like this one.
I have an audio recording if someone is able to give me some
(I have no way to analyze).
Any ideas ?
