Hi Kenny,

Treat it as a potential source of RFI, but don't assume that it WILL be 
unless there's variable speed-control of a motor.

We're also on a well, a Well-Xtrol-branded pressure pump controller and 
WX-302 pressure tank came with the house when we bought it 16 years ago. 
All of the wiring is either underground or in conduit, most of it around 
the unit is in flexible stuff, and the controllers are in steel boxes. 
There's also a Triple O-branded TWTS-101 ozone water treatment unit. The 
motor controller functions as on-off, not variable speed. Same for the 
well motor.

I just checked -- my Kenwood TH-F6A used as a probe for noise heard 
nothing around 2 MHz. If it's not there, I wouldn't expect to see it 
anywhere else.
