Yes, but I am specifically interested in what's going on near my
operating position. Have had some problems with computer peripherals
when transmitting on 80m.

This may be a better way of going about it:

I know I could just wind chokes to try and eliminate any common mode
rf at my operating position. I just like the idea of measuring first
to see how effective the chokes are.
