Gordon,

If such a connection is known, yes, that could be quite productive. I 
was completely unaware of it until you posted this information, AFTER I 
had made my post. It's great that ARRL offers this sort of service, but 
it does no good if it's not widely known.

Further, hams should NEVER, except in emergencies, reduce power because 
neighbors have equipment with high susceptibility. Those neighbors, if 
they have a problem, should be made aware that it's THEIR problem, not 
the ham's problem. This is especially true in the situation described -- 
the company who has created the problem won't talk to the ham. The 
neighbor is never going to call the DSL company to complain, because he 
has no problem. In the case described, the ham has VERY seriously 
limited his operation because his neighbor bought a lousy service!

The neighbor should be referred to the Class B or Class A statement in 
the product documentation. The ham should decide, on the basis of his 
perception of the relationship with the neighbor, how much, if any, help 
to offer. In some cases, the best approach would to have the neighbor 
contact the FCC. We all have had neighbors like that. :)
