This is a C-L-C type tuner with a reflected power indicator. Tuning
is done for minimum reflected power. Forward power indicator is
omitted because I know the output power of my transceiver anyway. Two
plastic-variable capacitors and a twelve-tapped
toroidal inductor are used.
Either unbalanced or balanced antenna can be used with a help of
built-in balun as shown in the figure at the bottom.
This design is very similar to that of St. Louis Tuner.
