Front Panel Controls
Figure 2 Front Panel
The front panel contains the following indicators and controls. To prevent damage,
become familiar with the front panel before operating the amplifier.
1. MULTIMETER Right scale FET Module Current, Voltage, ALC, and Reflected
Power. Left Scale Power Output. Multimeter (reflected power, module voltage,
ALC, or module current) selected by control 6.
2. BAND SELECT or REMote selector knob.
3. BAND INDICATOR or REMote backlit LED indicators, also warning if flashing.
4. ALC SET limit adjustment.
5. ALARM INDICATORS ALC, High SWR, PA Fault, and Transmit on.
6. MULTIMETER SELECTOR switch.
7. OPERATE/STANDBY switch, also resets fault warnings.
8. MAIN POWER switch, also resets power supply overload.
The meter’s left scale-arc (Figure 2, ref 1) continuously indicates forward peak envelope
power (PEP) output directly in watts. PEP has no fixed relationship to long-term average
power except, for constant amplitude carriers like a steady CW carrier, when PEP and
average powers are equal. PEP is the highest average power during one (or more)
radio frequency cycle(s) at the modulation envelope crest.
