CHAPTER 2 INSTALLATION

INSTALLING THE RADIO

Choose a convenient location for operation that does not interfere with driver or
passenger. This radio is supplied with a universal mounting bracket. When mounting
the bracket and radio to your car, make sure it is mechanically strong. Also, provide a
good electrical grounding connection to the chassis of vehicle. Proceed as follows to
install the radio.

1. Locate a convenient area in your vehicle for the installation of the radio. Hold the

mounting bracket with the radio in the location where the radio is to be installed.
Make sure nothing will interfere with either the radio or the mounting bolts. Mark
and then drill holes for the mounting bracket.

2. Most radio antennas come equipped with a PL-259 plug. Connect this plug to the

ANT. Jack in the rear of the radio.

3. Extending from the rear of the radio is a fused red and black wire for the DC

connections to the vehicle’s electrical system. For best performance, it is strongly
recommended that the red lead be taken directly to the positive terminal on the
vehicle’s battery and the black lead be connected to the nearest chassis ground.
(Note: This radio is designed for vehicles with negative ground systems.)

Connections should be made using appropriate “crimp on” lugs of a size large
enough to make good contact with the bolt used to fasten to the battery and the
chassis ground. It is a good safety idea to install a second fuse that would provide
protection in case the red wire was to “fray” or get pinched and short to the body of
the vehicle, somewhere between the battery and the radio.

High power radios such as this one require large DC current flow when in the TX
mode. Poor power connections cause supply voltage drops that can substantially
decrease the performance of your radio. A good DC connection is probably one of
the most important things for getting the best transmitter performance and in some
cases, least receiver noise.

4. Mount the microphone bracket near the radio in an easily accessible spot using the

two screws provided.

IGNITION NOISE INTERFERENCE

With weak signals, you may experience interference of the signal by background
noise. This radio has NB and ANL circuits which will help reduce background noise
from sources such as your ignition system. However, background electrical noise may
come from several sources and all noise may not be eliminated. With extremely weak
signals, you can operate this radio with the engine turned off, which should improve
reception. If the ignition noise level is too high to allow proper operation under most
conditions, you should have your installation of the radio checked by a qualified
technician.

ANTENNA

This radio has a jack in the rear for a standard PL-259 antenna plug. If you are
looking for the most range for your transmission, use a vertically polarized, quarter­wave length antenna. If antenna height is a problem, you may use a shorter, loaded-type
whip antenna although you can expect some loss of transmission range.

To improve performance, your antenna should be matched to your radio. Your
antenna can be adjusted so that it matches your radio.

EXTERNAL SPEAKER

The external speaker jack (EXT SP.) on the rear panel is used for remote receiver
monitoring. The external speaker should have 8 ohms impedance and be able to handle
at least 4 watts. When the external speaker is plugged in, the internal speaker is
disconnected.

PUBLIC ADDRESS

To use the Public Address (PA) function, first connect an external speaker to the PA.
SP. Jack on the rear of the radio. See the above specifications for a proper external
speaker. Keep the speaker away from the microphone to avoid acoustic feedback.

1. MOD LAMP: When switched on, this Modulation indicator will illuminate as you
speak into the microphone. When you speak louder, it appears bright because it is
on nearly 100 percent of the time and when you speak softer, it appears dimmer
because it is flickering on and off. It does not glow at all when there is no
modulation. This lamp operates in all modes.

2. SWR/MOD/PWR SWITCH: This switch controls the function of the meter
during the transmit mode. In the “SWR” position, the meter indicates the Standing
Wave Ratio (SWR) of your antenna (accurate at maximum power output). There
are no adjustments because the SWR circuit in this radio calibrates itself
automatically. When the switch is in the “MOD” position, the green scale on the
meter indicates your percentage of modulation in the AM mode only. It is most
accurate when testing at maximum power output. When this switch is in “PWR”
position, the meter indicates your power output.

3. MICROPHONE JACK: Used to connect microphone.

4. ON/OFF VOLUME CONTROL: This knob controls the volume and power to the

radio. To turn radio on, rotate the knob clockwise. Turning the knob further will
increase the volume of the receiver.
