MOBILE INSTALLATION
IMPORTANT
BEFORE DISCARDING ANY OF THE PACKING MATERIALS, EXAMINE FHEM CAREFULLY FOR
[ITEMS YOU MAY HAVE OVERLOOKED.
MOUNTING
For ease of mobile installation, the mounting cradle is designed to serve
as a means of mounting the transceiver in any convenient position in the
vehicle, After you have determined the location, hold the unit with the
bracket attached in che exact location desired. [f nothing inter- feres with
it, remove the bracket from the unit and use it as a template to mark the
location for the mounting screws. Before drilling the holes, make certain
nothing
will interfere with the installation of the mounting bolts.
POWER CONNECTION
The transceiver is constructed to be used in vehicles using either positive
or negative ground. The red lead is the positive lead and the black lead is
the negative lead, of the existing wiring, is used, be sure that it is heavy
enough to prevent voltage drop to the radio, A good source of battery voltage
is at the accessory connector on the ignition switch, Using this a5 4a power
source ensures the radio will be off when the ignition switch is turned off,
and power will be supplied to the radio only when it is in the ON or ACCESSORY
position. Determine whether your vehicle has a positive or negative grounded
battery system before connecting the power cable.
ANTENNA
Your transceiver has been adjusted at the factory to give optimum
performance using a 52-ohm antenna. There are a number of 52-ohm antennas
available for mobile use. For an automobile installation, a whip may be used
with good efficiency because the automobile acts as a counterpoise and reduces
detuning effects. The mounting location also has 2 great effect on the ef-
efficiency, The most efficient and practical installation 1s a full quarter-
wave whip mounted on the left rear deck of fender top mid-way between the rear
window and bumper. The so-called ‘’short whip” is a less efficient antenna
because the radiation area is reduced. However, full use of its capability may
be achieved since a shorter antenna may be mounted in a more ad- Vantageous
position on an automobile, such as in the middle of the top. There are also
newer mobile antennas on the market which are made to replace the
entertainment radio antenna and are similar in appearance. These antennas
serve three purposes: AM and FM entertainment broadcast reception and
transceiver transmission and réception. Your local dealer may be prepared to
offer advice and will help you choose the most desirable antenna for your
needs. To connect an antenna to the transceiver, a 52-ohm coaxial transmission
line is required.
INSTALLATION ADJUSTMENTS
The output circuit of the transmitter has been factory adjusted to operate into any good §2-chm antenna, No attempt should be made to tune the transmitter to the antenna, Instead, the antenna should be adjusted to present the lowest possible SWR (Standing Wave Ratio), A very low SWR means that the antenna is operating at maximum efficiency and will also mean that it is adjusted to 52 ohms. An Improperly adjusted antenna causes standing waves to appear on the feed line. Since this feed line is 2 fixed 52 ohms, and cannot be adjusted, this mismatch appears at the transmitter. If the transmitter is adjusted to compensate for this mismatch, both it and the antenna will no longer be operating at peak efficiency. Since the transmitter has already been adjusted for 52 ohms output and the coaxial feed line has a fixed 52-ohm value, the only remaining clement to be adjusted to this value is the antenna itself. When received, the antenna is pro- baby cut as near as is possible to this value, The mounting location on the vehicle or building and surrounding ob- jects affect the antenna, however, and requires that it be adjusted to compensate for them. Many of the newer 27 MHz antennas provide means of adjusting them for lowest SWR. Instructions for doing so are included with the antenna. For such antennas as the full quarter-wave Jength whip, it is necessary to carefully vary the length until the lowest SWR is obtained, For all adjustments to the antenna, connect an SWR meter in the feed line to the antenna. The unit will work into an antenna system having an SWR as high as 3: 1, For best communications, you will want this figure as near 1: 1 as possible 50 that the antenna will be operating at its best efficiency.
NOISE SUPPRESSION
This transceiver contains automatic noise limiter, noise blanket, and input power filtering. In most vehicular installations, the noise suppression for the entertainment radio will be sufficient. Vehicles not having this suppression may require that it be installed, In most cases, installation of distributor suppressors and generator condensers will be sufficient. In Severe cases, the services of a qualified technician may be required. See your local dealer for advice.
CONTROLS AND INDICATORS
FRONT PANEL
REAR PANEL
OFF/VOLUME CONTROL
This turns the power on or off, This also controls the sound output from the speaker. (The Volume control does not affect the transmitted output.)
SQUELCH CONTROL/CW MONITOR
squelch Control: To quiet undesirable background noises when no signal is re- ceived, rotate the squelch control clockwise. It functions only in the receive mode and does not affect the receiving volume during receive mode, Adjust this control as follows:
- Turn the power on and rotate the volume control until the background noise 15 heard.
- Rotate the squelch control clockwise until] the noise just disappears. Incom- ing signals will automatically release the squelch. (Take care not to rotate the squelch control too far as it de- creases reception sensitivity. }
CW Monitor: Setting this control to the fully counterclockwise position will enable you to monitor the CW tones while keying. The CW circuit is automatically activated by the insertion of a plug from the CW key into the Key jack located on the rear panel, (Keying the CW key during reception will automatically convert the unit to the CW transmitting mode.)
CLARIFIER
Used to shift both the transmitting and receiving frequency 4.5 kHz above
or below the assigned center frequency.
NB-OFF SWITCH
This reduces impulse noises such as ignition from vehicles, etc., without
significantly affecting the basic sensitivity of the receiver
DX-LOCAL SWITCH
Place this switch in DX position for normal reception, and in Local
position to receive strong or nearby station,
CHANNEL/HI-LO SWITCH
This switch selects the higher 40 channels. or Jowler 40 channels, in
conjunction with the Channel Selector (80 in all)
FINE-TUNING CONTROL
This permits slight adjustment of receiver tuning for 300 Hz above or below
the center frequency. Use it for clarity on SSH reception.
S/RF POWER METER
This gives the relative strength of incoming signals when receiving and RF
power output when transmitting, for all modes.
CHANNEL SELECTOR
This selects one of the 40 channels for either high or low bands desired. The
LED digital display will show the selected channel automatically.
MIC JACK
This accepts the plug from the microphone supplied with the unit.
LSB-USB-AM SWITCH
Place this switch in the AM position for standard AM [ransmitting and
receiving operation. The LSB and USB posinens are used to operate the unit in
the SSB mode. It should be noted that the CW mode of transmission and
reception can be achieved at all 3 positions of this switch.

- Place the LSB-USB-AM switch in the AM position,
- Adjust the Squelch control in the unoccupied channel.
- Select a channel you want to operate on by means of the Channel/Hi-Lo switch and the Channel Selector.
- You can use the Clarifier to shaft the operating frequency in between the adjacent channels.
- Use the Fine Tune control for the off-frequency stations, This allows you to vary the receiving frequency without affecting your transmitting frequency.
- To transmit your message, depress the push-to-talk button on the micro-phone; to revert the unit to receiving mode, simply release the button.
SSB OPERATION
- Place the LSH-USB-AM switch in the USB or LSE position. A station operating in the USB or LSB mode can only be communicated with a station operating in the same mode.
- Select a channel you desire,
- Use the Clarifier to shift the both transmitting and receiving frequency as you want, and use the Fine Tune control] to vary the receiving frequency only.
- To transmit, proceed as in AM operation,
CW OPERATION
- Plug the CW key into the Key jack on the rear panel. This will automatically disable the microphone audio circuit and convert the unit to the CW mode.
