Topband: DSL knocks out when on TopBand

[W2RU - Bud Hippisley]

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).
