Quick Connect - Mirage B 1018 G User Manual

0.0 QUICK CONNECT

1.) Mount or place the amplifier in a cool area. The best mounting position will place the long
length of heatsink fins vertical.
The amplifier must have sufficient cool air supply. Do not mount in confined or hot
locations, or where exposed to moisture.
2.) Connect the power leads to the battery or power supply.
Be sure to fuse the red positive-lead at the battery or power supply with a 30-ampere fuse.
The red lead must always be positive, with an operating voltage of 12-15 Vdc. We do NOT
recommend connecting the black lead directly to a vehicle battery terminal. Connect the
black lead to the vehicle's chassis with a good solid connection.
3.) Connect the radio to the UHF-style female RADIO connector with any length or type of
good-quality 50-ohm coaxial cable.
Any size or length 50-ohm coaxial cable will work on the INPUT, just be sure the jumper is
good.
4.) Connect the antenna (or power meter) to the ANTENNA connector through any length of
good-quality 50-ohm coaxial cable capable of handling 200 watts of power.
Any size or length 50-ohm cable will work, as long as losses are acceptable. The cable must
safely handle 200 watts at 150 MHz. Be sure connectors are installed and soldered
properly!
5.) The switches in this unit are self-explanatory. They are MODE, PRE-AMP, and POWER.
a.) The MODE switch adds time to the transmit-relay in the SSB/CW position. This allows
SSB or CW operation without excessive relay chatter or word chopping. It is normally
not necessary to use the SSB/CW mode position when using the RELAY port for relay
control.
b.) The PRE-AMP switch adds a low-noise receiver pre-amplifier, which improves signals if
receiver gain is marginal. In congested areas, it may be advisable to NOT use the pre-
amp to reduce receiver overloading.
c.) The POWER switch controls the transmitting amplifier, and resets any overloads.
6.) The FAULT light illuminates whenever excessive drive power from the radio is applied, or
reflected power from the antenna exceeds a preset value. This light indicates the protection
circuits have locked-on, preventing the amplifier from keying.
If the FAULT indicator is on, you must check drive power and antenna reflected
power. Drive power must be below 10 watts and Reflected power must be below
20 watts (at full output). If SWR is over 2:1, it is unacceptable to run this unit at full
power.
