Topband: DSL TB IX Cured

[Herb Schoenbohm]

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.
