A-1015-G Instruction Manual
6 Meter R.F. Amplifier

INSTALLATION
The Mirage A-1015-G may be mounted using the brackets (supplied when request is
returned via warranty card) or simply place in a convenient operating position. In either
case, there must be adequate ventilation for the finned heat-sink. This generally means at
least 1 inch clearance from the sink to any surrounding enclosure and an unobstructed
flow from the front to the back of the heat-sink.
CAUTION:
With extended use the heat sink becomes very hot. If it is necessary to
extend the D.C, power leads use a minimum #8 gauge wire.
Use a minimum length of good quality 50 ohm cable between the radio and amplifier.
The antenna system should have a VSWR of 1.5:1 or better for best performance. The
receiving pre-amp gain is set to the high value at the factory. To switch minimum gain
move the DIP switch located under the left side cover near the power supply that leads to
the down position. The switch may be accessed through the fourth slot from the front on
the right side using an appropriate small tool. If desired, the transmit relay hold-in (hang-
time) may be adjusted by adjusting the potentiometer located behind the third slot from
the amplifier. If external amplifier keying is desired, a switched ground connection must
be provided to the center pin of the RCA phone jack.
FRONT PANEL SWITCHES/LED'S
POWER ON/OFF SWITCH .....................Turns the D.C. power on or off.
CHANGE
FROM
SSB
TO
FM.................Selects relay time delay for the mode of
operation. The relay drop time is lengtened for
the SSB mode of operation. The adjustment is
accessible through the second or third slot on
the left hand side behind the front panel.
PRE-AMP ON/OFF SWITCH ..................Turns Pre-Amp power on or off.
POWER LED ............................................Indicates that D.C. power is applied.
PRE-AMP LED.........................................Indicates that the pre-amp is turned on or off.
TX LED.....................................................Indicates that the pre-amp is turned on.
SWR/OVERLOAD LED ..........................Indicates amplifier shutdown due to excessive
VSWR, temperature, or R.F. drive power.
REAR PANEL CONNECTORS
RADIO (SO-239) ......................................R.F. input from radio.
ANT (SO-239)...........................................R.F. output to antenna.
RCA phono (Unmarked) ...........................Remote keying.
Molex (Unmarked)....................................Remote control.
