Installing the Radio

Choose a convenient location for operation that does not interfere with
drive 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 the 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, in series with the red wire at the battery connection. This
second fuse would provide protection in case the red wire was to “fray”
or get pinched and short to the body of the vehicle, some where 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.

Chapter 3 Operation

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 controls 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, quarter-wave length antenna. If antenna height is a problem,
you may use a shorter, loaded-type whip antenna although you can
expect some lost 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. SPK) 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 4watts. 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. SQUELCH CONTROL: This control is used to control or eliminate
receiver background noise in the absence of an incoming signal. For
maximum receiver sensitivity, it is necessary that the control be
adjusted only to the point where the receiver background noise is
eliminated. Turn fully counterclockwise and then slowly clockwise
until the receiver noise just disappears. Any signal to be received
must now be slightly stronger than the average received noise.
Further clockwise rotation will increase the threshold level that a
signal must overcome in order to be heard. Only strong signals will
be heard at a maximum clockwise squelch setting.

2. ON/OFF VOLUME CONTROL: Turn clockwise to apply power to the
radio and to set the desired listening level.

3. RF GAIN CONTROL: This control is used to reduce the gain of the RF

amplifier under strong signal conditions.

4. MIC GAIN CONTROL: Adjust the microphone gain in the transmit

mode. This control is used to set the audio level of the microphone for
maximum performance and clarity.
