[RFI] Shielding a ground wire

[Aaron Kreider]

The ground wire is getting RFI because it's all over the house's 
internal AC wiring.

Side note:  I haven't yet tracked down any local noise sources because I 
rent out two apartments and I want to have the battery packs so I can 
take my whole setup portable (QS1R, laptop, and might try carrying the 
Wellbrook loop as some of the noises are weak).  I want to minimize the 
annoyance caused to the tenants and ideally deal with everything in one 
or two visits.
