The intermittent part makes me think that someone has one of those illegal
grow lights in your area. They are real RFI machines. They conduct into the
power lines and the source can be blocks away. Good luck!

 Hi Wes,   I am thinking that this should be hearable on your Car AM radio
as you drive by the villen. For a very short range test use the radio at the
lowest frequency ie 500KC.  For longer range use the same radio on the
highest frequency, IE. 1600 KC.  Day time might be best since the skip will
be weak.  Good luck!   DA
