transceiver.
WARNING
The Citizens Band (CB) Radio Service is under the jurisdiction of the Federal
Communications Commission (F .C.C.). Any adjustments or alterations which would
alter the performance of the transceiver's original F.C.C. Type Acceptance or which
would change the frequency determining method are strictly prohibited. Replace-
ment or substitution of Crystals, Transistors, ICs, Regul~tor Diodes or any other part
of a unique, nature, with parts other than those recommended by us, may cause
violation of the technical regulations of Part 95 of the F.C.C. Rules or violation of
Type Acceptance requirements of Part 2 of the Rules.
ELIMINATION OF LICENSING
The Federal Communications Commission (F.C.C.) has ruled that Citizens Band (CB)
Radio Service operators no longer are required to obtain an F.C.C. license to operate
their CB equipment. In doing so, the F.C.C. also decided to permit CB station
operation without station identification.
Elimination of individual station licenses results in no lessening of the operating
privileges or responsibilities of CB users. An operator of a CB radio station is still
required to comply with the Communications Act and with the rules of CB Radio
Service..

NOTE:
This radio has been designed for operation in the 11 meter Citizens Radio
Service. It uses a frequency synthesizing circuit with Phase Locked Loop
(PLL) techniques to provide crystal controlled transmit and receive opera-
tion on all 40 channels. The PLL circuitry assures ultraprecise frequency
control. It is designed to meet the Federal Communications Commission
requirements applicable to equipment operating in the Citizens Radio
Service, and is not to be used for any other' purpose.

INSTAllATION
Location
Prior to begining operation of the transceiver, a basic installation must be done.
Installation of the transceiver itself is a rather simple procedure.
In selecting the location for the unit, two factors must be considered:
~v
1. Access to a ~ AC, 60Hz power source for your BASE STATION installation.
Be sure to connect the AC power cord to an AC power source, not to a DC power
source.
2. The location must be convenient for running the antenna lead-in cable to your
transceiver.
BASE STATION ANTENNA
Since th'e maximum allowable power output of the transmitter is limited by the
F.C.C., the antenna is the most important factor affecting transmission distance.
Only a properly matched antenna system will allow maximum power transfer from
the 52 Ohm transmission line to the radiating element.
The recommended method of antenna tuning is to use an in-line watt-meter or VS-
WR bridge to adjust the antenna for minimum reflected power on channel 19.
The radio may be used with any type of 52 Ohm base station antenna. A ground
plane vertical antenna will provide the most uniform horizontal coverage. This type
of antenna is best suited for communication with a mobile unit. For point-to-point
operation where both stations are fixed, a directional beam will usually increase
communicating range since this type of antenna concentrates transmitted energy in
one di-rection. The beam antenna also allows the receiver to "listen" in only one
direction thus reducing interfering signals.
Antenna height is an important factor when maximum range is desired. Keep the
antenna clear of surrounding structures or foliage. F.C.C. regulations limit antenna
height to 20 feet above an existing structure.
MOBILE OPERATION/EMERGENCY POWER OPERATION
It is possible to operate the WASHINGTON from an external 13.8V DC power
supply for emergency power conditions or from an automobile battery for mobile
operation. The WASHINGTON is supplied with a polarized plug for operation with
an external DC su pply .
Negative lead is black.
Positive lead is red and has the in-line fuse holder as an integral part of the
positive lead.
~3-
PUBLIC ADDRESS
An external 8 Ohm, 4 watt speaker may be connected to the PA speaker jack located
on the rear panel when the transceiver is used as a public address system. The speaker
should be directed away from the microphone to prevent acoustic feed-back.
Physical separation or isolation of the microphone and speaker must be used when
operating the PA at high output levels.
REMOTE SPEAKER
The external speaker jack (EXT. SPKR.) 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.

OPERATING PROCEDURE
TO RECEIVE:
The WASHINGTON operateson 40 AM channels,40 Upper Side Bandchannelsand
40 Lower Side Bandchannels.
When you receive the SSB signal in the proper mode, audio sound may be either too
high pitched, or Iow pitched, indicating that your receiver may not be tuned to the
exact same frequency as the transmitter it is listening to. The WASHINGTON is
equipped with a Clarifier. By tuning the Clarifier, you can slightly change the fre-
quency of the receiver. $0, you can get a normal tone.
1.
Turn the SQUELCH control clockwise until click is heard, do not advance too
far or you will not hear any background noise. Advance the RF GAl N control
fully clockwise.
2.
Turn the set on by turning the VOLUME CONTROL clockwise, past click.
NOTE: Microphone must be plugged in for the receiver to operate.
3. Set the VOLUME CONTROL to a comfortable level.
4. Set the Mode Selector Switch to the desired mode.
5. Listen to t~e background noise from the speaker. Turn the SQUELCH CON-
TROL slowly clockwise, until the noise just disappears. The Squelch is now pro-
perly adjusted. The receiver will remain quiet until a signal is received. Do not
advance the control too far, or some of the weaker signals will not be heard.
6.
Set 1he Channel Selector to the desired channel.
7.
Adjust the CLARIFIER to clearly receive SSB or AM signals.
TO TRANSMIT:
CAUTION
The transmitter Voltage Standing WaveRatio (V.S.W.R.) measurementmust be
performed prior to the useof the transmitter. A.V.S.W.R. ratio in excessof
2:1 may damagethe transmitter.
1.
Be sure the operator has read and understands part 95, F.C.C. Rules and Regula-
tions prior to operating the transmitter.
2. Select the desired channel.
3. If the channel is clear, depress the push-to-tqlk switch on the microphone and
speak in a normal voice.

CONTROLS AND THEIR FUNCTIONS
0 unlden 0
~'OR'
.@J~JJM(6)N ~NA'@S.C~R 999:
1. ON/OFF VOLUME CONTROL: To turn the transceiver on, rotate the control
clockwise past click. To turn the transceiver off, rotate the control counter-
clockwise past click. Rotate the control for a comfortable audio level.
2. CHANNEL SELECTOR: This switch is used to select anyone of the 40 Citizens
Band channels. Channel 9 has been reserved by the F.C.C. for emergency com-
munications involving the immediate safety of life of individuals or immediate
protection of property. Channel 9 may also be used to render assistance to a
motorist.
3. CHANNEL 9 SWITCH: This switch is for use when emergency communications
is needed on the emergency channel, CH9. Pressing the CH9 switch activates
CH9 regardless of the position of the channel selector switch. When CH9 switch
is pressed, the channel display is blanked and the CH9 indicator is activated.
4. MODE SELECTOR: This switch selects AM, USB, or LSB mode of operation.
This selector changes the mode of operation of both transmitter and receiver
simultaneously. Set the selector to the mode on which you desire to com-
municate.
5. SQUELCH: The squelch control is normally set to a position which eliminates
undesired background noise with no signal present. With the audio adjusted to a
satisfactory level, rotate the Squelch control clockwise to the point where the
sound from the speaker is cut off. In this position, there will be no sound from
the speaker until a signal is received. In order to hear weak signals, it may be
necessary to rotate the Squelch control counterclockwise, allowing some back-
ground noise to be heard.
-6-
6. PA(Public Address) SWITCH: To engage the PA function, rotate the SQUELCH
control counterclockwise past click. Press the press-to-talk switch on the
microphone and speak in the microphone in a normal voice level. The PA
function should not be used unless the PA speaker is connected.
7. MIC GAIN: This control is used to adjust, as required, microphone input
sensitivity for the optimum amount of modulation in transmit.
8. RF GAIN: This control is used primarily to optimize reception in strong signal
areas. Gain is reduced by counterclockwise rotation of the control.
9. CLARIFIER: The clarifier is normally set to the center position. This feature
has several uses and can greatly enhance receiver operation. If a received signal is
slightly off frequency, th is control can be operated to optimize the received
signal. This control is primarily intended to tune in SSB signals, but it may also
be used to optimized the AM signal.
10. NB/ANL SWITCH: When the switch is placed in the NB/ANL position, the RF
Noise Blanker and Automatic Noise Limiter circuits are activated. The Noise
Blanker cut out annoying impulse-type noise such as ignition noise on both AM
and SSB modes. The Automatic Noise Limiter reduces most undesirable inter-
ference noises.
INDICATOR FUNCTION
1.
S/RF PWR METER: When the transceiver is in the receive mode, relative signal
strength is indicated in S units on the lower scale of the meter. When trans-
mitting, relative power output is indicated on the upper scale of the meter. When
the MOD-SIRF switch is depressed, the meter indicates modulation percentage.
2.
TX/RX INDICATOR: This indicator lights in red when the transmitter is in
operation and lights in green when receiver is in operation.
3.
MODE INDICATOR: This radio is equipped with mode indicator lights for AM,
USB and LSB modes. When you set the mode selector to the mode desired, the
related indicator light comes on.
4.
CH9 INDICATOR: This indicator lights when the CH9 switch is depressed.
