Hmm, funny that the DSL filter didnt help.


The relevant frequencies are 100 x apart, so the filter is super non
critical.

A couple of 2.5 mH chokes in series and two 0.01uf capacitors in
parallel will make a dandy filter, at least 40dB down. That's
roughly what's inside a DSL filter.

But again, I'd follow the investigative steps from my previous msg. it
won't do any good to place a good filter in a bad place.
