[RFI] Mystery Noise (Aren't they all)

[Wes Stewart]

 The co-op guy was out this morning and confirmed noise at this location.  He said that he found a source with the ultrasonic equipment.  Says it's loose hardware but he's still seeing some rfi from over the fence in the vicinity of the pump, although it's stronger from the pole.

 The last RFI job I did for another ham turned out to be a failing lightning
arrestor.  So, you have the pump house or one of several lightning
arrestors.
