Thanks, Lee. I am planning another DFing expedition asap. I'll look for those.
The local Power Company expert did some digging for me a couple of weeks
ago: he told me that a near-neighbor has a motor running constantly which
appears to have the bearings going out in it.
I know where this motor is, and even when I walk up within 2 feet of it, the
noise level remains the same, so, I have elminated that particular one from
consideration. Maybe I shouldn't...
