[RFI] DSL interference

My 17 year old son just came over complaining that I was screwing up the

I laughed and said not today as I have not been transmitting for the last
hour and he just got home.

Reminds me of times when my folks would get blamed for their neighbors
television issues.  I have not done any transmitting from their place for
almost 10 years.  I still have a couple of towers up.  My Dad loves to tell
them to jump to some other conclusion or jump in a lake HI!

Yes, that's pretty much the general direction I'm hoping to convince the
telco guy to move in, given that everything else I've tried so far hasn't
quite made the grade.  Unfortunately, we've been "enjoying" 40 mph winds and
blinding snow for the past 30 hours or so, and neither the telco guy nor I
have had much stomach for tackling that kind of project right now!

I didn't mention a couple of things in my first posting.  (rfman45,  
W2LO in TN, is going to love this story about his favorite telco....)   
We live on an inland lake, and we get our telephone service via underwater
lines from the other side of the lake.  My service comes up out of the water
to a telco pedestal in my next door neighbor's yard, then loops from the
terminal block in the pedestal back into the water and comes up out of the
water again near my boathouse and goes about
25 or 30 feet to the corner of the _old_ part of my dwelling where the NID
used to be located.  Since the boathouse is that much farther from the
vertical, and since it's sheltered and has power, and since it's essentially
one story below my first floor, shielded from direct line- of-sight to the
160 tower by the embankment it's cut into, I'm thinking a _wonderful_ place
for a NID and the DSL modem to be located would be inside the boathouse, at
deck planking level.  I just have to work a little harder to convince the
telco guy that a good ground rod there, rather than the AC service entrance
ground he prefers, will be sufficient.

At this point, I'm almost willing to trade the lightning susceptibility of a
fax machine or cordless telephone base station every three or four years for
peace in the family.
