Interesting effect of double filtering the phone - any thoughts

[#1]

Hi old jim,
Just noticed this thread.
For what its worth, I have been using double filtering for a long time (only one phone in use- a dect )
I found that it gives me a slight improvement to snr, which is very welcome on my long line.

I can't see how that would cause a problem.

Just plug 2 together and look again, you'll see.

It might be more helpful, particularly for those that don't have/use plug-in filters, if you would explain what the observed problem is (and the reasonings why if you happen to know).

Except that a filter connection wouldn't fit to the router side of the first filter so bad
