10-4, you are a jerk of the first magnitude and second order. Most of us
got our ticket to be on HF long before we figured out the subtleties and
nuances of RFI.

OP, you've got two problems. One is classic TVI and the other one is
direct rectification. Let's take care of the second one first.

Yes, your house intercom wiring is acting like a big antenna. Somewhere
in the wiring or at the intercom there is a rectifying junction (can be as
simple as the input transistor at the intercom or as subtle as a partially
corroded connection somewhere else. Coupl'a questions. Do you still get
the intercom interference when you are running directly into a dummy load?
Do you still get the interference when you load directly into a simple
dipole hung at some distance from the house on a temporary test?

Just FYI, the Feds have stated in no uncertain terms that
homeowner/municipal codes (CC&Rs, ordinances, building codes, etc.) canNOT
prohibit the reasonable erection of amateur radio antennas. "Reasonable"
has not yet been tested in the courts as to whether a hundred foot tower
with a ten element 80 meter beam with an aircraft prop motor for a rotor
is reasonable, or whether a 2-meter dipole made out of #40 wire painted to
match the house is reasonable. Put your damned antenna outside and let
the chips fall where they may. THe Feds trump any lesser governmental
restriction (state, county, city, or homeowner's group).


The Feds do trump state, county, and city ordinances though it can be a long
battle to get it done. However, they have also stated that in the case of
CC&Rs, PRB-1 does not apply as that is part of the contract that you entered
when you bought the property. There are bills being introduced to change
that but they have not yet been passed into law.
