Topband: QRM from DSL?

[Gullik Tjernstrom]

Hi all.

Have been running ADSL into my house for aprox. one and
a half year now, haven't had any problem so far. I also think
I have a "bad" case, in the sense of the location of the antenna
and the incoming phone line. One of my antennas on topband is
a full-size horizontal loop, yes, you all know, the famous cloud
warmer, or excellent-topband-high-angle-DX-antenna ;-)
The phone line elevates from ground to the top of a phone-pole
almost in the center of the loop. It then runs to my house
something like 25 meters, about 5 meter above ground.
The loop hangs something like 18 to 20 meters up. I haven't heard
any noise or traffic induced into the antenna, so far. The ADSL is
set for maximum speed, around 8 Mbit/sec downstream (QRO on the Internet, hi..)
so it utilizes all of it's spectrum, 256 freq/channels. Haven't had any
problem with the ADSL, due to radiation of RF into the phone line, guess
that's not so important.
Have relocated the loop this summer, but that's another story...
