Schematic 11

The Hy-Gain, Hy-Range II is a full 23-channel transceiver designed and type accepted for Class D
Citizens Band operation as designated by the Federal Communications Commission (FCC). See the
section on FCC Regulations for further information.
It is a completely solid-state, compact unit with high reliability and low power consumption. The system of
frequency synthesization provides immediate operation on all 23 channels without additional crystals or
adjustments. It features a delta tune control, which helps pick up stations that are slightly off-frequency. A
switchable automatic noise limiter (ANL) is included to help reduce atmospheric noise. The unit can be
used for public address with the addition of a PA speaker.
The Hy-Range II transceiver operates from 12 volts DC (nominal), either negative or positive ground. For
best results from your transceiver, please read all the instructions before beginning your installation.
Lfcen.lng Your Citizen. Two-Way Radio
Before doing anything else, fill out FCC Form 505 (enclosed) and send it off in order to receive your
Class D License as soon as possible. Mail the upper portion, along with $4.00 to:
Superintendent of Documents
Government Printing Office
Washington. DC. 20402
You should receive your Class D station license and a copy of Volume VI of the FCC Rules and
Regulations, which includes Part 95, within 60 days.
Legal Requirements
It is your responsibility to see that your unit is always operated in accordance with FCC Rules and
Regulations. Don't tamper with any internal adjustments; these adjustments can be done only by
someone with a first- or second-class radiotelephone license. Especially, be sure that only factory-
authorized crystals, transistors, and other components are used in this radio.
If your unit should need servicing, contact the nearest authorized Hy-Gain Warranty Service Station.
There is a list of these centers included with the radio.

Choose a convenient location that is protected
from moisture and heat, and be sure that the unit
will not interfere with your driving. Decide in
advance the best way to route the antenna coax.
Tools required for installation:
pencil center punch
drill pocket knife (optional)
drill bits (5/32 & 1/8 ) electricians fape
tape measure low heat soldering gun
phillips screwdriver rosin core solder (not
hammer acid core)
Mounting Bracket
Use the bracket as a template to mark where the mounting holes will be drilled. Measure carefully to be
certain the installation will be straight.
With a center punch, indent the marked areas. This will prevent the drill bit from skipping when the hole is
drilled. Dash Mounted

Attach the bracket with at lease three screws for a sturdy installation. Use the large thumb screws to
fasten the transceiver to the bracket.

The Hy-Range II may be operated from any 12 volt
DC battery system, either negative or positive
ground. Connect the red lead to a + (positive)
area of the electrical system, and the black lead to
a - (negative) area of the electrical system.
Some common connections areas for the red lead
are the accessory terminal on the ignition switch,
or the accessory side of the fuse block.
The black ground lead should be connected to the
metal firewall or any other small screw that is
connected to the vehicle chassis. For a more
secure connection, use solder or electricians tape
wherever necessary.
Coil any excess power lead and secure it in a place
where it will be up out of the way of your feet.
Don t Let Theft Happen to You
Each month thousands of CB radios are stolen out
of vehicles. These radios don't have to be gone
forever. Before you install your transceiver,
engrave some sort of identification number directly
onto the metal outer case. You can use the serial
number that is located on the plate on the back of
the transceiver, or your social security number.
The important thing is to keep a record of
whichever number you use. Ifyour CB radio should
be stolen, the identification number can be traced
back to you. This in itself often discourages would-
be thieves.
Antenna
Any of the following Hy-Gain antennas are suitable for use with the Hy-Range II transceiver. Mounting
instructions and hardware are furnished with each antenna.

Microphone Mounting Bracket
Install the mic-hanger bracket in an area which will
allow the microphone and its cord to hang in a
convenient position out of the way of your feel. For
example, mount the bracket high on the dash
where it is within easy reach.
Two optional speakers, the Hy-Gain 612 and 613,
can be used with the external speaker jack.
Instructions on how to mount are included with
them.
Any 8-ohm, 4-watt speaker could be used as well.
Plug the speaker cable plug into the external
speaker jack (3.5 mm plug required).
Telephone Handset, model 676, is available for
use with the Hy-Range radios. See the manual
supplied with it for instructions on its use.

Signal Strength/RF Power Meter
During reception, the built-in meter provides a relative indication of signal strength in
S units (lower scale). This provides a comparison between one incoming signal
and another.
During transmit, the meter provides an indication of your antenna rf power (upper
scale). As you speak, the pointer should flicker slightly, indicating that you are
modulating the rf carrier.
Microphone Jack
A power outlet for the microphone or the optional telephone handsel.
Power Switch/Volume Control
This knob turns the power on and off and controls the volume.
Squelch Control
The squelch eliminates background noise. Turn the knob counterclockwise until a
background noise is heard, then rotate the knob slowly clockwise until the
background noise just disappears. The receiver will be relatively quiet under no
signal conditions, but an incoming signal will overcome the squelch action and be
heard. As the control is turned clockwise, the squelch action is progressively
increased and stronger signals are needed to overcome il. To receive extremely
weak signals orto disable the squelch circuit, turn the control fully counterclockwise.
Channel Selector
Rotate the switch to anyone of the 23 channels, PA position.
Power Cord
See Installation Section
Fuse
Uses a 2-amp, 3AG fuse.
External Speaker Jack
The 3.5 mm jack accommodates any 8-ohm, 4-watt speaker.
Remote Speaker Jack
This jack is used with the optional Telephone Handset, Model 676.
Delta Tuning ( ~ Tune) Control
Used to fine tune stations that are slightly off-frequency. Set it on the position that
provides best reception.
ANL (Automatic Noise limiter) Switch
When placed in the ON position, this switch reduces undesirable atmospheric-type
noises.

Operating
Procedures To Receive
1. Turn the volume control clockwise and adjust it to a comfortable listening level.
2. Set the channel selector on the desired channel and readjust the volume control
as necessary.
3. Adjust the squelch control slowly clockwise to the point at which background
noise is quieted.
CAUTION
Do not try to transmit without aproper antenna connected to the antenna jack of
the transceiver or you could seriously damage your transceiver
A Reminder: Don t transmit until you have sent Form 505 to the FCC and
have received your Class D License.

Noise
Suppression
2. Press the push-to-talk (PTT) button on the microphone and hold it down. Hold the
microphone four to six inches from your mouth and speak at a. normal level.
Announce the call letters of the station you are calling, followed by your call letters.
Repeat if necessary. To receive a reply, sign off and repeat the call letters of your
station.
PA Public Address)
1. Connect a external PA speaker to the PA jack on the rear panel.
3. Press the push-to-talk button on the microphone and talk into the mic. Your voice
will be heard from your external speaker.
NOTE: The volume control on the transceiver does not control the speaker output
during PA speaker.
Tune-up
Before beginning any special noise suppression steps, be sure that the
vehicle is well-tuned. Clean and tighten all connections, including alternator,
battery, regulator, and coil connections. Perform the following maintenance
steps as necessary: Solder any cr(mped spark plug or distributor leads; if you
must use solid-wire leads, clean and regap or replace spark plugs and
ignition points; and check and clean alternator rings or generator brushes.
Retune the engine at the manufacturer's recommended intervals.
Corrective Steps
In order to find and eliminate the maximum number of noise sources that are
present in any vehicle, start the strong sources, then work back. To be sure
the noise comes from your vehicle and not outside it, drive to a location that is
free of man-made electrical interference (such as noisy power lines,
industrial noise, or other vehicles). Test for noise with a weak signal on the
channel and the engine off. Then start the engine. Ignition noise will probably
be present at all engine speeds. If it is severe, it will make a normally readable
signal unreadable.
To reduce ignition noise, install resistor-type spark plugs. If non-resistance
ignition wiring is used, install a 10 k-ohm suppressor resistor at each spark
plug tower of the distributor. Install a coaxial capacitor as close as possible to
the ignition coil primary.
A whining noise which varies with engine speed and continues with the
ignition turned off and the vehicle coasting in gear characterizes the
alternator. Check and clean it and install an alternator filter.
An irregular, clicking sound which disappears at a slow idle may be the
voltage regulator. Install a 4-ohm carbon resistor as close to the field terminal ••
of the regulator as possible, then a .002 uF capacitor in series with and as
close to the resistor as possible. Connect the capacitor to ground. See the
detail drawings on next page.
Irregular popping noises which vary with road surfaces indicate static
discharge at any of several locations in the vehicle. Tighten loose nuts and
bolts and bond large areas such as the fenders, exhaust pipe, firewall, etc. to
the frame with lengths of heavy wire braid. Contact a local electronics parts
or automotive electrical service company to purchase the necessary items.
Additional information is available in the Radio Amateur s Handbook
published by the ARRL.
