Adjust C56 on the LPA for minimum reverse swr detector voltage
(typically 3 mV).
17.6 FREQUENCY CALIBRATION
Is factory set only.
Note: Any adjustments made to the SG-2020, besides R46 CW
sidetone are NOT covered by the warranty.
17.7 NOMINAL OUTPUT POWER TEST
Set output capability of the transceiver by setting the output level to
“20”. Set generator to 1300 Hz 20 mV AF input to the microphone
connector; measured output power level should be:
1.8 - 25 MHz
20 watts ± 3 watts
above 25 MHz
14 watts minimum
17.8 STRESS POWER (MAXIMUM OUTPUT POWER)
Set maximum output capability of the transceiver by setting the out-
put level to “M” for maximum. With 20 mV AF input at the micro-
phone connector output power level should be:
Frequency
Power Range
1.8 MHz
23 to 27 watts
3.7 MHz
23 to 35 watts
7 MHz
30 to 40 watts
14 MHz
35 to 45 watts
18 MHz
30 to 42 watts
29 MHz
14 to 23 watts
The above readings are for reference and orientation only and may
change without notice.
ATTENTION: The above stress power test should not be extended
more than ten seconds.
This test is not covered under warranty.
