I agree it would be best to search through the neighborhood but that assumes I
have portable equipment / antennas to do this. Right now all I have is the AM
radio in the truck and will do some driving around on my way home from work
later today.
I was thinking that I could use the 6 meter beam on the tower to maybe provide
some directivity clues.
I thought the cycle time would be a clue (as was pointed out possibly a heater).
There are many noise sources around me with power lines surrounding the
property, Industrial buildings across the street with a shopping center beyond
them.
I agree, time to start digging.........

I agree it really is a waste of time to try to analyze the symptom. The
next step is to locate it.. using the highest frequency that is detectable
on utilize attenuation to narrow down the area. Always maintaining the
lowest level of sensitivity in your search. Be absolutely certain that what
you find is the actual cause and the same source and not something similar.
