Herb (& others) —

I struggled to keep my 160- and 80-meter RF out of my DSL equipment for a 
number of years.  Multiple turns of all cables in/out of the DSL modem (Siemens 
Speedstream) on #31ferrites, etc.  The best progress occurred when I wrapped 
the modem in common kitchen aluminum foil and very carefully attached a ground 
wire to the foil.  (Use very big flat washers on both sides of the foil!)  But 
I still experienced occasional disconnects.

This past year my telco started supplying Westell Model 7500 DSL modems to new 
customers and my favorite telco tech saw that I got one, too.  I haven't 
observed a single DSL outage since then.  And I haven't even wrapped it in 
aluminum foil!

Other things that will help:
   *  If you can do it, relocate your incoming telephone line and/or your 
160-meter antenna (and its radial field) for greater separation of the two or 
for altered orientation between the two.
   *  Get your 160 (and perhaps 80) antenna farther from both the outdoor telco 
line and the indoor telco lines (i.e., your house).
