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  

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.
