[Elecraft] Like MFJ's 931 Artificial Ground ?

[Stuart Rohre]

The nice thing about the Ten Tec kit, is that it can be easily converted to
an "L" network tuner, if you switch the point where the pick up circuit
monitors current, and substitute a coax jack for the connection in one
original hole.  That way, it can be converted back to artificial ground
service by use of a shorting plug, if I remember the scheme I used some
years ago.
