Controller Unit:
Antenna matches are stored into a bank of 85 memory locations. Each memory location is
a fraction of an amateur band. Refer to the technical section for the fractional segments for
each band. As shown in the picture below, the upper line of the LCD shows the actual
memory location chosen (lower edge frequency 1840 kHz) with its span (20 kHz). The
control settings for this frequency are shown in the lower line of the LCD. In the Automatic
Mode the memory location and its stored settings is selected by the transmitted input
frequency. The input frequency is obtained from an RF probe. The memory location
contents can be erased by a push button on the back of the controller.
The controller contains 3 rotary encoders that control the tuner elements TRX, L, and ANT.
TRX controls the Input Capacitance, L controls the Inductance and ANT the output
capacitance values. The lower line on the display shows these values.
A manual selector switch is provided for memory selection in the Manual mode.
