Exactly, thanks Stu!

The XPNR will absorb noise above and below the X10 120KHz.  I am not sure how sharp it is tuned so it could reduce the Insteon 131.65KHz slightly.

If you are unfortunate to have noise on 120KHz it may not do any good at all.

The are no fine tuned X10 or INSTEON powerline filters. In fact, the band is so broad and the powerline frequencies of X10 and INSTEON are so close, that a filer for one is as effective as a filter for the other.

 

BTW, the filtering is purposely kept wide to inhibit even a close signal from being misinterpreted. That's because the filter has two purposes. It blocks noise that's close to the signal frequency from escaping (signal stomper) and it keeps signals out (signal sucker).

How does that XPNR Pro Noise filter work. I put that in the electrical box behind the SwitchLink? Is there room for that?

Yes, the filter is installed inside the electric box. It may not fit with a SwitchLinc. The usual placement is the fixture box. In that case, you should install one in each fixture box that supplies a neon light.

 

BTW, I rarely get personal on a forum, but this brings back a vivid memory. When I was a youngster, my dad was foreman of a neon sign shop and, for one birthday, he had a congratulatory sign made. And there was my name up in flashing neon lights

I decided to keep it simple and get the FilterLinc. Things appear to be working fine. I haven't seen one error yet. Sometimes it take an extra 1 or 2 seconds to turn off, but all seems well.

 

Thanks again everyone.
