INSTALLATION
ELECTRICAL Set controls as follows, with Power cord removed:
(1) Power switch: OFF (2) Squelch: Minimum (3) Volume: Minimum (4) Scan: AUTO (5) Priority: OFF
(6) Individual channel selector switches: ON position (7) Insert desired crystals in proper positions
(8) Connect antenna cable
(9) Plugin the proper power cord and connected to voltage source (either 13.8V DC or 117V AC)
For Mobile operation the DC Power cord can be wired for negative ground. Turn the Squelch control to the minimum position. Turn power switch to “ON”. Turn the volume control towards maximum. A rushing sound will be heard in the speaker; advancing the volume control towards
maximum will increase loudness of noise.
When the squelch control is slowly turned towards maximum, a point will be reached where the background noise will disappear. This indicates normal squelch operation and this is the proper position for scanning.
MOBILE INSTALLATION
A. A mounting bracket and hardware is provided so that the unit may be conveniently mounted under the dashboard of any car or truck. Refer
to figure 2 for UNDER-DASH BOARD MOUNTING. B. The Gladding COMANCHE 16 is designed for use in Negative Ground
Vehicle.
Connect the red fused wire of the power cord to the “hot” side of the ignition switch, or directly to the positive terminal of the battery. Connect the black wire to any convenient chassis ground.
MOBILE ANTENNA The mobile antenna represents an electrical quarter-wave length at the operation freqeuncy, or physically represents about 19″ at 150MHz. Shorter equivalents are the “loaded” type of antenna, and are usually placed
in the center of the roof for maximum effectiveness.
MOBILE NOISE SUPPRESSION
Mobile noise is present in all automobiles but can be reduced if desired by using standard ignition, suppression and bonding techniques.
MARINE ANTENNA AND INSTALLATION The antenna system for a boat should be a ground plane type antenna. The
common name for such antenna is coaxial or ground plane antenna. The same bonding and ignition suppression techniques may be appied to a boat as to an automobile.
BASE ANTENNA AND INSTALLATION
To install this receiver in a base installation, screw in Telescopic whip antenna (accessory) into the hole of cabinet, simply connect the AC power cord to the rear panel connector and plug the cord into a 110–120 volts AC 60Hz power source. For best operation a permanent type antenna is recommended. Wire the antenna coax lead-in to a RCA type Phone plug and insert this in the antenna jack on the rear panel. The base antenna should be as high as possible and can be of the ground-plane variety.
FRONT PANEL CONTROLS
A. ON-OFF POWER SWITCH Turn power switch to “ON” position.
B. VOLUME CONTROL Turn the volume control clockwise and advance the volume control until you hear a rushing noise. Then adjust this control to a comfortable listening level.
C. SQUELCH
The squelch restricts the background noise output until a signal is received. Slowly turn the control clockwise (making sure there is no station transmitting on the frequency) until the background niose just disappears. If the control is increased past this point, it will take a much stronger signal to override the squelch, thereby not permitting weaker signals to
be heard.
. SCAN CONTROL
The SCAN control switch from automatic to manual scanning, in which case the “CHANNEL SELECTOR” switch must be used to switch channels.
. SCAN SPEED CONTROL
Rotate the Scan speed control enables a choice of scanning speed.
.
CHANNEL SELECT
Push the channel selector
switch
to
obtain
your
desired
channels
(i=
#16 ch.). Scan control switch must be in the Manual position.
. PRIORITY
Channel 1
Note that operation,
is always the priority channel.
regardless of which channel (from
2
thru
16
inclusive)
is
in’
the UNIT will always search Channel 1 every 2 seconds for
a duration of only 40 milliseconds.
Should a signal be present on Channel
1
during searching, Channel 1
will
lock-in, regardless of the fact that a signal is being received on another
channel at that time; at the same time, the Carrier Delay feature will not
allow further scanning until any carrier on Channel | is absent for more
than 2 seconds. The priority feature is operational during both “AUTO”
and “MANUAL” Scan. The significance of the Priority feature is pointed
out by the fact that in any given area there is usually one channel much
more important than the others. By inserting the most important
frequency crystal in the channel | position, the operator is assured of
always hearing transmissions of that freqeuncy, regardless of the activity
on the other channels.
. INDIVIDUAL CHANNEL SELECTOR SWITCHES
These push-buttons allow individual channel selection for programing
either the automatic or manual scanning operation.
. MODE SWITCH
Rotate the mode switch to obtain your desired modes. In the mode marked “Hi”, this unit scanning from channel | to channel 8. Marked “Hi/Lo”, scanning from channel 9 to channel 16 in these channels, High and Low combination. Marked “ALL” scanning from channel | to
channel 16.
.
BYPASS
This feature prevents the scanner Any one or more channels may be
from being locked on bypassed by releasing
a busy frequency. the corresponding
channel switches.

CRYSTAL INSTALLATION
Sixteen crystal sockets are provided–8 sockets designated for high band only and another 8 sockets for intermix use between high band and low band. The sockets for CH1 through CH8 are for high band crystals only, and the sockets for CH9 through CH16 can be used either for high band or low band
crystals by connecting jumper connectors to the pins designated for high
band and low band respectively. Figure 1 designated factory inserted jumper connectors, that is, from CH9 to CH13 connected High band and from CH14 to CH16 did Low band. If you wish to receive another band, you should insert the jumper connector into the pins in the desired band corner (High or Low).
The ability to program any channels to operate on low band or high band on CH9 through 16 at will gives you great flexibility.
CRYSTAL CORRELATION
In order to obtain the correct crystal to monitor a specific channel the following formula must be followed to obtain the crystal frequency.
HIGH BAND 1. CRYSTAL FREQUENCY = DESIRED CHANNEL ——er — 10.7MHz
Example:

GLADDING COMANCHE 16 possesses an inherent high rejection of unwanted signals due to the sensitivity of the R.F.Stage. THE CHART indicates the sensitivity for 20 db quieting when a channel is removed from center frequency (where the receiver has been peak tuned at 40MHz). When the receiver is peak tuned at 40MHz, sensitivity is within 6 decibels from 37MHz to 43MHz. If you want to change the tuned channel higher or lower, you must adjust for Maximum sensitivity at a DESIRED CHANNEL FREQUENCY within the specified band coverage (30–50MHz). Adjust L109, L110, L111 and L112 for Maximum sensitivity. Coil numbers
are printed on the printed circuit board.

THEORY OF OPERATION-RECEIVER(HIGH/LOW)
The COMANCHE 16-VHF-FM Monitor receiver is a conventional double conversion superheterodyne circuit, employing Intermediate Frequencies of 10.7MHz and 455KHz. Modern design philosophy is employed throughout as demonstrated by the use of Low noise RF transistors, integrated circuits, monolithic quartz crystal 1st IF filter, and ceramic 2nd IF filter. Refer to the schematic diagram for the following description of circuit
functions and operation.
The received signal from the antenna is passed to a dual tuned input circuit. The signal is then amplified by Q101/Q106 and passed through another dual tuned bandpass network to the mixer stage, Q102/Q107. The mixer is fed with the VHF signal and the local oscillator to provide an IF output signal of 10.7MHz. The local oscillator uses following formula.
High band–….. fo = 1480–.7MHz_ 3
fs ; channel frequency Low band::-:—- fo = fs + 10.7 MHz
The mixer output is passed through a monolithic quartz filter to obtain a high degree of adjacent channel rejection. The use of the monolithic quartz crystal filter in the 1st IF stage provides greater suppression to intermodulation and spurious than conventional LC networks. Intermediate frequency signal of 10.7MHz is fed to the 1st IF amplifier Q301. Q302, the second mixer has an output of 455KHz which is coupled to
ceramic filter HF302. Local oscillator injection voltage for the second mixer is obtained from the 10.245MHz crystal controlled oscillator, Q305. The output of the second mixer is passed through a 455KHz IF ceramic filter to the IF amplifier/limiter IC (LA1201) which brings the signal to a level sufficient to operate the detector and squelch circuits. The ceramic filter which is connected to the output of the second mixer, provides a very narrow band-width and can be obtained greater suppression of adjacent channel and inter-modulation. A Foster Seely detector, composed of T303, T304, D301 and D302 are used to receiver the frequency modulated audio. The output from the Foster Seely detector is amplified in a conventional manner by Q701 and Q702. The output from Q702is directly coupled to the push-pull audio output stages, Q703 and Q704. ‘ The DC output from the squelch detector, emitter of Q304 is amplified by Q501 and Q502. Q502 also serves as a DC amplifier to provide the squelch voltage to Q701.
12
DIGITAL SCANNING SECTION
The digital switching circuit is composed of IC’s sequencially selecting the sixteen crystal controlled frequencies in the local oscillator circuit of the receiver. Sequential selection by this electronic switching circuitry is called “scanning”. Scanning signal generator Q507 and 508 arein the form of a conventional free-running astable multivibrator. The scanning signal is added to the gate circuit of the crystal oscillators through frequency divider IC501 and IC502, and nand gate (D506–D5 13). When a signal input developes in the tuner, scanning is stopped instantly. It is that signal added to the scanning signal generator Q507 and 508 that stop tha scanning through IF amplifier, IC301, squelch circuits (Q501 and Q502) and carrier delay networks (Q503, Q504 and Q505). Thus the operation of the multivibrator is stopped and locked in to the signal incoming channel. The signal incoming channel light is also turned on. This scanning operation can be manually controlled by pushing a channel selecting button.
HIGH AND LOW BAND INTERMIX SYSTEMS
Each of the 8 channels (#9–16 ch.) in this model can be used for either the High or Low band as desired. Insert the jumper connector into the desired channel terminal in the High band corner if the crystal is for the High band or in the Low band corner if the crystal is for the Low band.
PRIORITY
1C503 is priority search signal generator.
When the priority switch is placed in the “ON” position, the unit will always search channel 1 every 2 seconds for a duration of only 40 milliseconds. If priority channel signal is received, stop the priority search signal generator 1C503 and lock in to the priority channel.
