[VHFcontesting] UPS with no radio noise???

[Marshall-K5QE]

Hello everyone....I got an MFJ-856(power line noise detector) assembled 
today and was preparing to go outside and look for all the nasty power 
line noise that we have.  I happened to wave it around the shack and I 
found some strong noise.....tracing it down, we found that all of our 
APC UPS systems(except one) were emitting a boatload of RF crap!!

We also found a simple power strip that was radiating like crazy.  How 
can a simple power strip produce loads of RF junk???  Beats me.

So, now I need to replace all my UPS units with something that does not 
make noise.  I have asked a salesman type person and they don't have a 
clue about RF noise.  None of the UPS units seem to pay any attention to 
that...it certainly is not part of their specs.

Does anyone know of a brand / model of UPS that does not emit a bunch of 
RFI??  I don't need a huge UPS for each station, but I need something 
that is quiet.  AFTER we fix the noise in-house, we will go outside and 
start with the noise that is coming in on the antennas.  I know that I 
have a bunch of power line noise too, but I need to have a clean house 
before I start with the power company.

I also want to find some power cords, like those on computers and 
monitors, that have the built in noise suppressors.  I don't know where 
to order those from either.

Thanks for any advice / recommendations.  If anyone works in that world 
I would really appreciate hearing from them.

I hope to get these UPS units replaced before the CQ WW VHF 
contest......by the way, I will be looking for everyone on 6M and 2M in 
the CQ contest....18 and 19 July....
