Thanks to all that responded. The SNR on my DSL line is unaffected by any
amount of ferrite I hang on the line, so that is good. However, the recommended
filter using four 6.8uh chokes and 3 caps completely cures the problem. I can
run a full KW output of dits and surf web pages with no dropouts. I built a
second filter for the house phone and it cured any RFI and setting off the
ringer.
I used some leftover DSL splitters for the enclosures. Gutted the original
board and mounted the new parts without even having to drill any new holes in
the PCB.
My SNR was marginal 6.8 - 7.3 usually. I cleaned and tightened the connections
on the incoming block and it went up to 8.8. I run CAT 5 from the block about
70 feet to the modem.
