Jason,
The first thing I would do is get the CATV people involved as there is
probably some sort of leak or ground problem on their end. Is the neighbor
tied in with the cable for broadband Internet?
Once the cable people check out their stuff, then continue down the RFI
path. Your neighbor needs also to know there is nothing you can do to
prevent his speakers from detecting your signal as they are not
radios. Also, how old is the neighbors TV? Do you get interference on
yours? Which channels? If it's CATV channel 18, then it is definitely the
cable problem as they use ham radio frequencies for their channels. Are
other neighbors having the same problem?
You should also contact your ARRL section technical advisor and get him/her
involved.
Good Luck
