This is not an uncommon problem. Cable channel 18 (I think) is right in
the middle of the 2 meter band. If the cable system has a leak or the
customer has a leak in the house, they will pick you up on cable. Unless
running a kilowatt, it is not likely your problem. I do know that the
coax cable connectors that people can buy from Radio Shack or others
that slip on instead of screw on have caused all types of problems. Try
working with your neighbor and check his coax cables throughout the home
usage and insure that are tight and not the slip-on type. If all seems
well, then it is likely that the cable company has a leak at one of
their cable junctions or amplifiers.
Also tune around for any unknown weak signals on two meters that do not
appear to go away. If you hear any, you might wander around with a
handi-talkie and see if you can isolate the problem. Remember, you are
operating two-meters and are licensed to do so. The cable companies must
protect the two meter frequencies from being interfered with and for
them not to interfere. The key here is to be civil and work with them to
show them the error of their ways.
