[Lowfer] Hz question.

[KD7JYK DM09]

I have an idea, want to run part of it by the LF guys.

I have a single wire, part of a 3-wire 60 Hz 120VAC system.  I want to 
monitor any RFI there may be on the wire in a very simple fashion.  I figure 
a could "sample" it by running the AC wire through a torroid, possibly a 
ferrite tube, possibly a binocular torroid, then wrap a few turns of a 
sampling wire through the torroid as well, then tap into this secondary for 
analysis.

Comments or suggestions?
