The LOAD TUNIG KNOB has to be rotated
clockwise.
While rotating the LOAD capacitor the CAP
METER is close to the optimum tuning
point.
We are next to the optimum point. Just a
small correction of LOAD and TUNE will
be necessary to reach the point.
Here, we have found the optimum point for
the LOAD Capacitor. Now we can release
the PTT and increase the drive power.
After pressing the PTT again it might be
possible to readjust the amplifier a bit.
