Hmmm...I had not thought of the "orthogonal" bit, Bill, but of course, you're correct.

The trouble with actually accomplishing that by raising the far end of the wire to point at the 
noise source would be difficult in this case, since the noise source is both much higher and 
too close to the end of my wire.

I DID find this link today which gives me a lot to think about:

It is looking like my next purchase is going to be an MFJ-1026.

Thanks for all the help and ideas, Folks.

I am still going to make a short "dxpedition" to a quiet(er) location with one of my Stoddart 
loops and an R-23A/ARC-5 just to see what I can hear.

I'll be running everything off batteries, and will be using a rebuilt dynamotor with the ARC-5.

I'll report here when I get that done.
