Hi Alan,
There is a little device called a "TVI" filter that your neighbor can insert between his radio's output and his antenna. It should solve the problem and clear up the RF. The TVI is very cheap and if your neighor is at all friendly and a responsible ham operator he should have no problem what-so-ever in adding the filter.
