[Elecraft] OT A/C RFI

[Fred Jensen]

We had a well for 38 years, went through three 4 HP down-hole pumps, and 
I never observed any RFI from it or the control/capacitor box at the 
well head.  The 240 V service to the entrance was buried.  The pump ran 
a lot when the irrigation system was on [making Pacific Gas & Electric 
very happy [:-( ].  Our neighbor's A/C, about 200 ft from my tower was 
something else again.
