CPU
-. The transmitter/Receiver/PLL section.
10.2 The Control Section
. The heart of the control section is the CPU,which is IC201 located on the
CNTL PCB. The CPU controls all of the following items:
-. Controls the Squelch circuit by detecting a busy signal from the 2nd IF
circuit IC3 on the RF PCB.
-. Generates a beep tone when a key is activated on the keyboard.

-. Controls the LCD display.
3. 3 The transmitter/Receiver/PLL Sections
In reading through the following circuit descriptions, it may be helpful to
refer to Block Diagram of the TX/RX/PLL circuits.
10.3 1. PLL(Phase Lock Loop) Circuit
PLL circuit of this radio is PLL IC(IC2) and is composed of VCO circuit which is for
Transmitter and for Receiver independently. PLL IC(IC2) generates the setting
frequency based on the control data of CPU(IC201).
The reference oscillating frequency of the PLL circuit is 21.25MHz and is consisting of
crystal resonator X1 and IC2. This oscillating frequency 21.25MHz is divided into 1/850
to make 25KHz-reference frequency.
Transmit frequency is generated on the Inductor and Capacitor circuit with connected
to IC2 pin 4,5.
The frequency control voltage, which is output from IC2 pin 7, will be input into Variable
Capacitance Diode(D6) on Inductor and Capacitor circuit.
The receiver local frequency is generated on the Inductor and Capacitance circuit with
connected to IC2 pin 20, 21.
The frequency control voltage, which is output from IC2 pin 18, will be input into
Variable Capacitance Diode(D5) composed on
The oscillating frequency 21.25MHz which is output from IC2 pin 11 will be used for the
second local frequency of Receiver and it will be input into IF IC(IC2) pin 1.
10.4 Transmitting Circuit Operation
3.4.1 Microphone Amplifier Circuit:
Voice signal from the mocrophone goes through pre-emphasis circuit consisting of
C147 ,R104 and is amplified in MIC AMP IC8(A).
Pre-emphasis can be output by Diode(D10). The level of the signal is limited by D7
and adjusted in the VR4.
Limiter output is amplified by IC8(B),then it goes through the active 4-stage LPF
consisting of IC8(C) and IC8(D). 4-stage LPF output goes into Variable Capacitance
Diode(D7) and then it makes Frequency modulation.
3.4.2 Transmit Frequency Power Amplifier Circuit
RF signal from the PLL IC(IC2) pin 1 goes through the 10dB attenuator consisting of
R37,R38,R39 and will be amplified by Q11. Output from Q11 will amplify drive power
necessary for the Q4 and Q3. power module(IC5) will be amplified and the RF signal
will be output to the antenna switching circuit. 4-stage LPF consisting of L21 and
L1-L3 is used to improve the level of Transmission Spurious Emission. RF output
from the power module(IC5) can be changed by changing the voltage of IC5 pin2.
3.4.3 APC Circuit
Diode D4 is monitoring a part of the power module’s(IC5) output. The monitoring
signal will be output to IC5 via switching transistor Q8 and display the “TX ON” and
the LCD.
The output voltage from IC5 controls the RF power to keep the RF output at a
constant level.
3.4.4 DSC Signal Treatment
In DSC mode at CH70,a sequence signal from CPU is input to MODEM IC(IC11) and
converted to an analog signal. As a MODEM TX signal,this signal switches the analog
switch(Q20) from microphone input position to DSC position. Then DSC signal is sent
out to the transmitter microphone amplifier.
If NMEA information are input to P501 connector through GPS or other devices
connected to it,these information are taken into CPU through photo-coupler of Q22
and can be transmitted with DSC to provide information such as position and time.
3.5 RECEIVER CIRCUIT
3.5.1 Antenna Switching Circuit
A signal received at the antenna connector J501 goes to high frequency amplifier circuit
via 4-stage low pass filter consisting of coils L1-L3 and L21.
3.5.2 High Frequency Amplifier Circuit
RF signal goes to the 1st mixer circuit through 2-stage BPF(consisting of coil L5,6) and
will be high frequency amplified by Q1 and then 3-stage BPF(consisting of L8,L10,and
T3) . The 1st image spurious frequency will be rejected to the adequate level in the
5-stage BPF inside the high frequency amplifier circuit.
3.5.3 1st Intermediate Frequency Amplifier Circuit.
A double balanced mixer(DBM) of IC1 is used for 1st mixer of Receiver.
RF signal from RF Amplifier circuit input to IC1 pin 6. Receiver local frequency input from
PLL IC(IC2) pin 20 to IC1 pin3 and then converts the frequency.
The converted 1st IF signal(the frequency of 1st IF is 21.7MHz) goes through 1-stage
crystal filter(F1) and is amplified in transistor(Q2)
3.5.4 2nd Intermediate Frequency Circuit
The 1st IF signal is added to IC3 and converted to 2nd IF signal. The 2nd IF signal goes
through F2 and amplified in the IC3 and then through discriminator CD1 and the
demodulated AF signal is output from IC3.
3.5.5 Low Frequency Circuit
The AF signal demodulated in the IC3 goes through the de-emphasis circuit consisting of
operational amplifier IC4(A) and R127 and C45. A 3 stage active HPF consisting of
IC4(B) ,C48,C49 C50,R23,R24 and R25 is used to reject AF signal below 300Hz. The AF
signal from the 3-stage HPF goes through AF Volume VR301 and is input to the speaker
amplifier circuit IC9.
3.5.6 Audio Muting Circuit
The Q18 to mute the audio is controlled by input of squelch’s BUSY signal and the
mute output of the CPU(IC201).
3.5.7 WX Alert Detection
The tone selector IC10 detects the 1050Hz alert tine if it is contained in the
re-modulated AF and WX alert tone will be output from the speaker.
3.5.8 DSC Signal Treatment
If the re-modulated signal arriving is a DSC signal, it is input to MODEM IC(IC11) as an
RX MODEM signal, and converted to digital signal. Undergoing the treatment in the CPU
circuit, this digital signal changes the operation state to DSC mode.

5. ELECTRICAL CONNECTIONS
5.1 DC Power, External Speaker Connections and NMEA Input
The 6 feet long power cable assembly consists of the DC power cable and the
external speaker cable. The DC power cable is composed of RED(+) and
BLACK(-) wires, and the external speaker cable has YELLOW(+) and
GREEN THICK(-) wires and NMEA Input has GREEN THIN(+) and BROWN(-). The
RED(+) wire with an in-line fuse(10 amps.) and the BLACK(-) wire of the 6 pin
connector cable are used for connecting the RAY53 to the ship’s 13.6 VDC power
system.
In most cases this length should be adequate enough to reach the DC power
source.
If additional wire length is required,the cable can be extended by adding more
cable as necessary. However,for power cable runs longer than 15 feet,larger
wire diameter size should be used to prevent voltage line loss.
Your RAY53 radio should be connected to the nearest primary source of
ship’s DC power. A typical source may be a circuit breaker on the power
panel or a fuse block near the unit. When connecting to either of these
sources, the circuit breaker or other in-line fuse should be rated at 10 amps.
It is recommended that lugs be used to connect the power cable to the DC
supply and the lug connections should be both crimped and soldered. This is
very important in order to insure adequate currect draw to the equipment.
intermittent operation may result if an insufficient connection is made to the
power source. the connection terminal should be clean, with no sigh of
corrosion.
The RED(+) wire is connected to the positive terminal of the power source or
battery. The BLACK(-) wire is connected to the negative(ground) of the power
source or battery. Should the power connections be inadvertently reversed,the
10 amp.in-line fuse located in the RED(+) wire will open. Check the input
power leads for correct polarity with a VOM(volt/ohm meter),reconnect the
leads observing correct polarity,and replace the fuse. Use the same rate and
type fuse.
-The RAY53 accepts NMEA 0183 data from a GPS or Loran navigator to provide
Lat/Lon position information that is transmit during DSC Distress Call mode. The
NMEA sentences that could provide positional data,by order of priority are:
GGA.RMC,RMA,and GLL.
5.2 Antenna Connections
The coaxial cable to your VHF antenna is intended to be connected to the antenna
jack on the rear panel using a PL259 VHF type connector. The antenna cable may be
cut to the required length at installation. If a longer cable length is required, RG-58 50
ohm coaxial cable or equivalent cable may be used for runs up to a maximum of 50
feet. If the distance required is even greater,then we recommend using low loss
RG-213 or equivalent cable for the entire run in order to avoid excessive losses in
power output.
If the antenna RF connector is likely to be exposed to the marine environment, a
protective coating of grease(similar to Dow Corning DC-4) can be applied to the
connetor before connecting it to the radio. Any other extensions or adapters in the
cable run should also be protected by silicon grease and then wrapped with a
waterproofing tape.
5.3 Antenna Mouting Suggestions
The best radio in the world is useless without a good antenna location. Mounting the
VHF antenna properly is very important because it will directly affect the performance
of your VHF radio. A standard VHF antenna which is designed to use aboard boats
should be used.
-. Since VHF transmission are essentially Line-of-Sight,mount the antenna at the
highest possible location on the vessel and free of obstruction in order to
obtain maximum range.
-. Use an antenna with highest possible gain characteristics.
-. If you must extend the length of the coaxial cable between the antenna and the
Radio, use a coaxial cable designed for the least amount of power loss over
the entire cable length.
-. Keep the coaxial cable between the radio and antenna as short as possible.
5.4 Grounding
While special grounding is not generally required for VHF radiotelephone
installations, it is good marine practice to properly ground all electronic equipment to
the ship’s ground system. The RAY53 can be connected to ground by attaching a
wire to one of the screws on the unit’s rear panel and then to the nearest ship’s
ground connection point. The recommended wire to be used or such grounding is
#10 AWG.
RAY53’s cabinet was specially designed and die-cast from aluminum to insure
maximum noise rejection from external sources
