INTERNAL ADJUSTMENTS
SSB DELAY ............................................................. This allows the R.F. relay
"hang-time" or delay to be
adjusted to the time desired.
PRE-AMP ATTENUATOR SWITCH ..................... Sets the pre-amp gain to full
or reduced value.
INPUT VSWR AND OUTPUT POWER ................. These adjustments are made
at the factory and should not
require field adjustment.
PRE-AMP TUNING ................................................. These adjustments are also
made at the factory for best
gain and noise figure
performance. They should
not require field adjustment.
TROUBLESHOOTING
The Mirage C-2512-G is designed for long, trouble-free performance and should not
require extensive troubleshooting in the field. Many causes of common malfunctions are
eliminated by the built-in protective circuitry.
NOTE: In the event of automatic power
shut-down, the amplifier must be turned off, and the cause of shut-down determined
and removed.
In case of difficulty check the following before assuming amplifier
malfunction:
a. Loose antenna or power supply connections.
b. VSWR of antenna system.
c. Coaxial cables from radio to amplifier, and amplifier to antenna.
d. Output voltage of power supply.
e. Power output of radio.
f. Improper fuse rating.
