[RFI] Which Filter is best?

[Dave Cole (NK7Z)]

Hello all,

An old grow operation has come back to life this week, and I expect I 
will be chatting with the operators in a few weeks.  I am in the data 
collection stages now, so I have some time...  I want to make sure it is 
a grow operation, and that I can document it if need be.

I will be suggesting the use of a commercial RFI filter set, (such as 
the Nanolux RF Reduction Filter Set), to the growers, and perhaps 
purchasing that filter set(s) for them as well.

I want to do this only once if possible, so I am looking for input from 
folks that have either used commercial filter sets, or tested commercial 
filter sets.  Which one did you use, or test, and did it work?  If so 
what were the conditions?  What was starting RFI levels, how far did it 
suppress them etc.

I have looked over the ARRL page, (http://www.arrl.org/grow-light-rfi), 
and Tom's page, 
(http://tomthompson.com/radio/GrowLight/GrowLightBallastFilter.html), etc.,

I am now looking for real world experience with commercial filters in 
order to give myself the best chance of killing this off ASAP, without 
FCC involvement.

I want commercial filters in order to minimize my liability, as opposed 
to home brew filters.
