I'm cross posting this for obvious reasons.

I pass this information out to those who may have similar problems with
DSL crashing while operating on 160 meters. (The DSL service uses
frequencies very close to the 160 meter band for which some sort of
filtering is required.) Since so many different circumstances of
antenna/grounds/ house wiring and positioning of the telephone drop wire
can vary, it was hard to find a solution to allow 160 meter operation to
co-exist with a functioning DSL.
At my shack I have three internet services, two WI-Max and one DSL via
the telco company. For remote control operations via either Icom's
RS-BA1 or Remote Rig's unit for the TS-2000 the DSL is the most
reliable. The WI-MAX units have plenty of bandwidth but the latency is
not as good as the DSL which gives me the most superb ability to run a
CW paddle from the remote end thousands of miles away with out the
"drunken CW syndrome" that the WI-Max is known for.
The one major problem with the DSL is that every time I would key on 160
the DSL would just shut down and loose connectivity completely. I tried
building filters, toroid wraps and even shielded tel-co wiring but
anything over 50 watts on 160 cause a disconnection using the DSL
service. I tried four different DSL modems, still no improvement.
Then Dan, K3ZXL suggested I try a filter made by Westek Electronics,
their type TC-Z100B1 telephone DSL line filter, which I ordered right on
line from their website at www.westek.com.
The item cost only $8.50 with shipping cost of $5.95. After
installation all the interference which used to crash the connection is
gone. Shipping cost were $5.95. Now running a full KW on 160 is
possible after plugging this filter between the wall jack and the DSL
modem.
