Fellow topbanders,
I know this is not a new subject but I would appreciate any
suggestions you may have. I did quite a bit of web searching before
posting here, but didn't come up with much. Please reply direct so
we don't clog up the reflector with this.
I knew DSL modems and 160m don't mix, but I am trying it anyway.
It's the only way I can have anything but dial-up. The problem, of
course, is that when I transmit on topband the modem loses sync. It
only takes 50 watts to do it. Not good.
Would winding several turns of the DSL and/or modem power cables on
a toroid potentially be helpful? I'm thinking common-mode
suppression here. Would 43 or 77 material be better? If this is
worth trying, I will order some cores Monday.
Any other thoughts?
I have considered going to shielded telephone wiring in my home, but
am not sure that would accomplish anything as I would still have the
100 foot long unshielded parallel-conductor drop from the pole to my
house, which is not far from my 160m antenna.
I have 768K DSL, so I assume it uses frequencies well below 1.8 MHz.
Is it possible to use a low pass filter on the DSL line to attenuate
1.8 MHz while letting DSL signals pass? I've never seen nor heard of
such a device...
Thanks,
Paul N1BUG
