[BC] BE tuner and such

For the unknown lead, a piece of one inch copper strap
12 to 15 inches long is very useful.

Second, make sure the bridge is grounded at its ground
terminal. Necked down 3 inch or 4 inch strap tied into
the station ground strap as close to the bridge as 
possible is an effective way of reducing inductive
reactance in the ground connection.

It is better if you don't depend on the initial balance
very heavily. Try to get the test lead inductance out
of the picture by removing it.

This is where newer devices, even going back as far as 
the vector voltmeter, RFVNA's, and now the AIM-120 have
a tremendous advantage in that they all use a cable and 
probe from instrument to measurement.
