 1. OPERATION  1.1 INTRODUCTION Your RAY53 has the capability to transmit and receive on all available US,International and Canada Marine VHF radiotelephone channels. There are channels that are FCC approved but may only be used by authorized stations for specific purposes, depending on the type of vessel (commercial or noncommercial.)  Refer to Table 1-1 . These table list all of the marine VHF channels available in your RAY53 for Canada,International and U.S. radiotelephone use. Full familiarization with this table is essential when selecting your channels. The International frequencies were agreed upon by the attending countries at the 1968 International Telecommunication Union meeting in Geneva and are in active use around the world. The US channels are those channels authorized for use in the U.S.A. by the FCC.  1.2 CONTROLS AND LCD DISPLAY                                                                                    1)                                                                                                     4)      5)     6)     7)     2) 3)    1.2.1 Controls 1) Channel Selection (Knob) -.

Setting the Power Output 1) Simply press the “MON 1/25” key for two seconds to toggle between 1 Watt output and 25 Watt output.  When “1 WATT” is displayed,the output power is 1 Watt.  If “1 WATT” is extinguished, 25watts is being output. The choice of power output is dependent upon the distance of transmission and transmitting conditions. In certain US harbors and on certain channels, the FCC requires the power to be limited to
1 Watt.  On these “required “ channels,the radio automatically selects 1 Watt power output when the channel is selected.  1.3.4   Selecting the Channel 1) To select the appropriate channel, rotate CHANNEL SELECTION Knob clockwise / counterclockwise or also press UP/DOWN key of the microphone. 2) The channels which are not set on the frequency mode are skipped . 3) When UP/DOWN key is continuously pressed for over 0.5 seconds,the channel is continuously changed(+1 or – 1) every 100msec during pressing UP/DOWN key.  1.3.5   To select the frequency mode     1) The frequency mode(group) can be selected from US mode, International mode and          Canadian Mode.        The frequency mode can be shown on the LCD as follows.        USA frequency mode----------------------------à  “INT” and “CAN” are eliminated        CANADIAN frequency mode------------------à  “CAN” is displayed and “INT” is                                                  eliminated.        INTERNATIONAL frequency mode----------à  “INT” is displayed and “CAN” is                                                   eliminated.       When WX/INT key is pressed and held for over 2 seconds, one frequency mode      can be changed to the other frequency mode and Alerm 1 is heard.:      For example:      When USA mode is in use,it can be changed to CANADIAN mode by doing above      operation.      When Canadian mode, it can bew changed to International mode. When      International mode,it can be changed to USA mode. The last changed frequency      mode can be memorized.      When the power is turned on,the last memorized frequency mode can be      used.(Channel number is16CH at that time.)  1.3.6 To Transmit 1) Press the Push-To-Talk switch(PTT switch)  and speak into the microphone using a  clear normal voice. 2) If the current channel is Weather CH or the Tx prohibited channel, PTT switch cannot be used and Audible beep sound 2 is heard.
3) RAY53 is designed to meet the new FCC Rules Part 80.203, which states,if the PTT switch is pressed continuously for over five minutes,transmission is forcibly inhibited. If this occurs,audible beep sound 2 will be heard until the PTT switch is released.  1.3.7 To select a Weather Channel 1) Simply press the WX/INT,then use Channel Selection Knob or UP/DOWN key to  select the desired Weather Channel from 0 to 9.  When this mode is selected,the         transmitter is always inhibited. 2) When the Weather CH is finished by pressing WX/INT key,the last used Weather CH number is memorized  3) When the power is re-turned on,the memorized Weather CH number can be activate on the Weather CH mode. 1.3.8   Priority Channel  1)When 16/9 is pressed and released, Alarm 1 is heard and Priority Channel is in use then     Channel Display(Small) shows “P” on the LCD.(“P” display means “Priority CH”.)   2) When 16/9 key is pressed and released again during “P” is diplayed, Alerm 1 is heard        and the channel will be returned to the privious Working CH. When the channel is    changed by UP/DOWN key during Priority CH is displayed, “P” display will be      eliminated and Workimg CH will be in use.  3) When 16/9 is continueously pressed for over 2 seconds, Alerm 1 is heard and Priority    channel can be changed either 16CH or 9CH.(When Priority CH is 16CH, it can be      changed to 9CH and when Priority CH is 9CH,it can be changed to 16CH.)  1.3.8 Channel Memory 1) The RAY53 has the capability of memorizing all US,International and Canadian    Channels. The channels memorized will be scanned in the Memory Scan mode. 2) Channel Memory: When SCAN/MEM key is pressed and held for over 3 seconds,the                  audible beep sound 1 is heard and the selected current channel can                  be put into memory.                  When the displayed channel on the LCD is memorized, “MEM” is                  displayed on the LCD. Memory Clear   : To press and hold for 3 seconds when the memory channel is                  stored, the audible beep sound 1 is heard and the channel can be                  cleared                      When the displayed channel is not memorized,”MEM” is not
                     displayed on the LCD.  1.3.9 Scan Modes  The RAY53 is equipped with two types of scan options, All-scan and Memory Scan. How these options are accessed is dependent upon whether there are any channels stored in memory.  1) All-Scan mode If no channels are stored in memory,when the SCAN/MEM key is pressed and released, the audible beep sound 1 is heard and ”SCAN” will begin to flash on the LCD for three seconds. If no other keys are pressed in these three seconds,the radio will begin scanning all channels(except weather channels) as long as no signal is received.  If a signal is received,the scan will stop on the receiving channel. If the signal is lost for five seconds, the radio will resume scanning. While the radio is scanning ALL-Scan,”SCAN” is displayed on the LCD. To cancel the scan mode,press the SCAN/MEM key while the radio is scanning. 2) Memory Scan mode If one or more channels are stored in memory,when the SCAN/MEM key is pressed and released,  the audible beep sound 1 is heard and “SCAN” and “MEM” will begin to flash simultaneously on the LCD for 3 seconds. If no other key is pressed in these three seconds, the radio will begin scanning all channels currently in memory.(Begin Memory scanning) As with All-Scan, If a signal is received,the scan will stop on the receiving channel until the signal is lost for five seconds, the radio will resume scanning. While the radio is scanning Memory Scan, “SCAN” and “MEM” are displayed on the LCD.  To cancel memory scan,press the SCAN/MEM key while the radio is scanning.      When SCAN/MEM key is pressed again during “MEM” flashing within these three     seconds, the audible beep sound 1 is heard and “SCAN” will flash on the LCD and the    radio will begin ALL Scan mode. “MEM” will disaprear from the LCD leaving only “SCAN”     flashing.  1.3.10   Monitor operations  1) The RAY53 is equiped with 2 types of monitor operations, Dual Watch opeartion and     Tri Watch operation.

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.
