Topband: DSL TB IX Cured

[Jeff Woods]

*Clap clap clap*

Thanks, Herb.  Just ordered one.  I have the same problem, and have attempted the solutions you describe below with respect to 160m interference to our DSL modem.  

My family will appreciate having internet during CQ160 this year.

>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.

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.
