Operation
8. Check the following parameters on the front panel multimeter:
a. RF Power should be 500–550 watts.
b. SWR should be less than 1.25 (A reading greater than 1.25 indicates an
antenna mismatch).
c. ALC should be between 4.00 and 6.00 volts.
d. PA DC Volts should be 46–56 volts. (Varies with antenna match, power,
and frequency.)
e. PA DC Amperes should be 12–16 amps. (Varies with antenna match,
power, and frequency.)
f. PA Temperature should initially read 20–35 degrees C (room tempera-
ture). After one hour the reading should be 35–50 degrees C.
g. Supply DC Volts should display a typical reading of 65–70 V with the
carrier on and 80–85 V with the carrier off
h. Voltmeter should be reading 0.0.
The remainder of this section describes the functions of the front panel indicators
and switches.
