DIRECT MODE:
•
DMY LOAD selects the internal dummy load, bypassing the impedance
matching circuit but providing normal meter readings.
•
BYP selects the BYPASS connector on the rear panel, bypassing the
impedance matching circuit but providing normal meter readings.
•
COAX 1 selects the COAX 1 connector, bypassing the impedance matching
circuit but providing normal meter readings.
•
COAX 2 selects the COAX 2 connector, bypassing the impedance matching
circuit but providing normal meter readings.
TUNED MODE:
•
COAX 2 selects the COAX 2 connector through the impedance matching
circuit.
•
COAX 1 selects the COAX 1 connector through the impedance matching
circuit.
•
WIRE selects the WIRE connector through the impedance matching circuit.
•
DMY LOAD selects the internal dummy load through the impedance matching
circuit.
5. INDUCTOR
12-position rotary switch to vary inductance.
6. RANGE
Two-position push button switch selects the range of FOWARD and REFLECTED
Power displayed on the power meter.
When the RANGE switch is OUT, the FOWARD meter scale reads 300 watts full
scale and the REFLECTED meter scale reads 60 watts full scale. When the switch is
IN, the FOWARD meter scale reads 30 watts full scale and the REFLECTED meter
scale reads 6 watts full scale.
7. LEVEL
When the level control is adjusted to light the red LED at 100% CW power, the
digital bargraph will indicate relative peak on SSB. When this control is turned fully
anticlockwise, the switched position turns off the meter lamps and the digital
bargraph.
8. DELAY
The delay control adjust the rate at which the digital bargraph returns to zero. This
control is set according to the operators discretion.
9. DIGITAL BARGRAPH
20 segment LED bargraph which displays peak power. The right-hand LED is red,
indicating 100% power.
