My s-meter is also a few bars on a LCD, which is why I thought being
able to read the voltage directly would be handy. Now that I think
about it, I can read the S-meter voltage through the serial port.

The difference between the 1ft and 2ft loop is a big deal in that the
smaller loop has deeper nulls and was much more accurate.

There is no theoretical reason why a 1' loop would have any different nulls
than a 2' or 10' loop ( at the freqs we are discussing).
If the nulls are deeper than there is a balance problem with the 2' loop.

I agree- LCD (digital ) S meters are of little value here.

I suppose the larger loop can couple to my body easier than the smaller
loop, though technically my body is in the null of the loop. Come to
think of it, my body would be very "near field", so that probably isn't
true.

I was thinking maybe I can find some coax that will fit tightly in
copper pipe so that I could use a shield. Do you think that would help
the null?

The reason I need copper pipe is that I need the construction to be
very rigid so that I can accurately align the compass to the loop.
