While Frank and I don't always agree on how much one should speculate, I
must agree with Frank in this case... Too much speculation, to early.
Do your power off test of your home, walk the area, borrow someone's
mobile rig... Collect some data, keep a log, etc... Then after you
have a lot of info, start guessing, but never let it shade what you are
looking for...
Take a look at:
http://nk7z.net/category/info/mitigation-of-rf-interference/
This is a collection of what I think are helpful articles on dealing
with RFI. Some of them outline the tools, some outline what to do, some
of them are preventative in nature. Sort of an overview in several
articles. It is sort of a multi year running blog of RFI adventures...
