SECTION 4
TECHNICAL DESCRIPTION
4.1 GENERAL
The RAY106 can be considered as consisting of two major sections.
• The Control Section (consisting of the front panel controls, LCD display, and CPU).
• The Transmitter/Receiver / PLL Section.
4.2 THE CONTROL SECTION
The heart of the control section is the CPU, which is IC101 located on the CPU PCB. The
CPU controls all of the following items :
• Controls the Squelch circuit by detecting a busy signal from the 2nd IF circuit IC101 on the
Main PCB.
• Generates a beep tone when a key is activated on the keyboard.
• Mutes the transmitter modulation circuit when receiving.
• Controls the output power of the transmitter High/Low.
• Controls the dividing ratio N of the PLL circuit.
• Switches ON/Off the transmitter power.
• Mutes AF audio.
• Detects a weather alert signal (when in Monitor Mode).
• Controls the LCD display.
4.3 THE TRANSMITTER/RECEIVER/PLL SECTIONS
In reading through the following circuit descriptions, it may be helpful to refer to Figure 4-1
Block Diagram of the TX/RX/PLL circuits.
4.3.1 PLL (Phase Lock Loop) Circuit
The PLL circuit is oscillating the standard frequency with the PLL IC ( IC3 ) and 12.8MHz
crystal filter XTL1. This is divided into 1/512 in the IC3 to make 25KHz reference frequency.
RF output from VCO unit ( VCO1 ) will be input to PLL IC ( IC3 ) pin8 via buffer amplifier Q10.
The dividing ratio data stored in the CPU IC101 will be output to pin10 and clock signal will be
output to pin9 of the PLL IC ( IC3 ). And when the chip enable signal is input to pin11 of PLL
IC ( IC3 ) the dividing ratio data will be latched to the PLL IC ( IC3 ). The phase of the
frequency which is a input frequency to the PLL IC ( IC3 ) divided by the CPU stored dividing
radio and the 25KHz reference frequency is compared correlated to control voltage by charge
pump transistors Q11, Q12. That is input to the pin of VCO unit ( VCO1 ).
4.3.2 Transmitter Circuit
1) Microphone Amplifier Circuit
Voice signal from the microphone goes through pre-emphasis circuit consisting of C109,
R110 and operational amplifier IC103 - 1/2. The level of the signal is limited by the D101
and adjusted in the RV101 and amplified in the IC103 - 2/2. Then it goes through the
active 4-stage LPF consisting of IC102 etc., and modulated in the VCO unit ( VCO1).
2) High Frequency Power Amplifier Circuit
RF signal from the VCO unit (VCO1) goes through the 10dB attenuator consisting of R27 -
29 and will be amplified by Q6. Output from Q6 will amplify drive power necessary for the
FET power module (IC1) in the Q5. FET power module (IC1) will be amplified and the RF
signal will be output to the antenna switching circuit. RF output from the FET power
module (IC1) can be changed by changing the voltage of IC1 pin 2.
3) APC Circuit
Diode D3 is monitoring a part of the FET power module’s (IC1) output. The monitoring
signal will be output to IC101 via switching transistor Q1 and displays the “TX ON” on the
LCD. Voltage of monitoring signal will be compared and amplified between the set
standard voltage and IC2. Then the output voltage goes through buffer amplifier transistor
Q4 and will be connected to the pin 2 of FET power module (IC1) and make it a APC
control loop. Output power can be changed by controlling transistors Q2, Q3, and Q7 with
the CPU IC101 to change the set standard voltage.
4.3.3 Receiver Circuit
1) Antenna Switching Circuit
Signal received at the antenna connector J201 goes to high frequency amplifier circuit via
the 3 stage low pass filter consisting of coils L1-3.
2) High Frequency Amplifier Circuit
RF signal goes to the 1st mixer circuit through 2-stage BPF (consisting of coil L9, 10 and
L11, 12), and will be high frequency amplified by Q8 and then 2-stage BPF (consisting of
L14, 15 and L16, 17). The 1st image spurious frequency will be rejected to the adequate
level in the 4-stage BPF inside the high frequency amplifier circuit.
3) 1st Mixer Intermediate Frequency Amplifier Circuit
A single balanced mixer type consisting of transformer T1 and diode D5 is used in this
radio. The 1st IF signal from the mixer circuit goes to the 2nd mixer circuit through 2-stage
crystal filter (F1 and F2) and amplified in Q15 of the 1st IF amplifier circuit.
4) 2nd Intermediate Frequency Circuit
The 1st IF signal is added to IC201 and converted to 2nd IF signal. The 2nd IF signal goes
through FIL201 and amplified in the IC201 and then through FIL202 and the re-modulated
AF signal is output from IC201.
5) Low Frequency Circuit
The AF signal re-modulated in the IC201 goes through the de-emphasis circuit consisting
of R204 and C209 and will be amplified in the Q201. A 2-stage HPF consisting of Q202,
C210, R212, C220 and R211 is used to reject AF signal below 300Hz. The AF signal from
the HPF goes through variable resistor RV202 and is input to the speaker amplifier circuit
IC104 and amplified to the set output level.
6) Audio Muting Circuit
The Q105 to mute the audio is controlled by input of squelch’s BUSY signal and the mute
output of the CPU IC101.
7) WX Alert Detection
The tone selector IC105 detects the 1050Hz alert tone if it is contained in the re-modulated
AF and the WX alert tone will be output from the speaker.

Hz10 Hz on the frequency counter. (See Fig. 5-6.)
5.4 TROUBLESHOOTING GUIDE
Table 5-4 provides a general troubleshooting chart for use by a technician to isolate circuitry
failures to specific functional areas within the RAY106.
The first step in attempting to clear a problem associated with the general operation of this
radio is to perform a MASTER RESET. This can be done by simply holding down the 16PLUS
key while turning the radio on. This should be performed anytime a component or PCB within
the radio is replaced. This function will clear the memory of the 106 and return it to the original
factory settings, 16PLUS will automatically be reprogrammed to channel 16.
NOTE:
Micro-components within the radio are generally not field replaceable, therefore, repairs to the
radio typically go down to the PC board level only. A replacement parts list for the RAY106 can
be found in Section 6.

APPENDIX
7.1 VHF MARINE CHANNEL USAGE GUIDE AND LICENSING REQUIREMENTS
Most of the information found in this section is reprinted in whole or in part from FCC
Information Bulletin No.2 REVISED EDITION February 1991 and FCC Fact Sheet PR5000
March 1990.
REMEMBER:
Maintain a radio watch on Channel 16. Channel 16 is used for distress and safety purposes
only.
Use VHF Channel 70 only for Digital Selective Calling (DSC). It may be used for generalpurpose calling using DSC. Your cooperation in not using Channel 70 for general intership
communications is necessary to prevent interference.
Your VHF transceiver has a high-low power switch. Use low power whenever feasible.
Unnecessary high-power operations can interfere with other important communications.
Always use your radio call sign at the beginning and end of each transmission.
Be sure only qualified persons operate your radio. You are responsible for control of your
radio. Know the rules.
Limit calls to other vessels to 30 seconds. If you receive no reply, wait 2 minutes; then try
again. Keep communications brief and avoid chit-chat.
Never transmit false distress messages, and never use profanity of the air.
OTHER REMINDERS:
Do not install or operate your radio until it is licensed. You can obtain a station license and call
sign by completing FCC Form 506 and mailing it with the required fee to the FCC, Marine Ship
Service, P.O. Box 358275, Pittsburgh, PA 15251-5275. Form 506-A provides you with
immediate operating authority, valid for 90 days after you mail your license application.
you need a radio operator license to operate VHF Marine Radio only if you plan to dock in a
foreign port or leave a foreign port to dock in a U.S. port.
Your radio license is not transferable. If you sell your boat, request the FCC to cancel your
station license.
If you replace your radio, you do not need to change your license unless the new radio
operates on another frequency band. If you install equipment to operate on another frequency
band, apply for modification of your license.
If you carry more than six passengers for hire, your vessel must be certified as a passengercarrying vessel by the FCC and the Coast Guard.
Licensing Requirements for Hand Held Portable VHF Marine Transceivers 10 Watts Power or
Less
All transceivers, handhelds included, operated in the Maritime Radio Services are required to
be operated under and appropriate maritime station license. Operation of hand held VHF
Marine transceivers without proper station license can lead to fines and/or administrative
sanctions issued against its user and/or owner.
VHF Marine hand held transceivers can be operated and licensed as follows:
a)Associated Ship Unit: A hand held VHF Marine transceiver can be operated under an
existing valid ship station license under the following conditions only:
i)Except for safety purposes, the hand held transceivers must be used only to communicate
with the ship station with which it is associated. Such associated ship units MAY NOT be
operated from shore.
ii)The transmitting power is limited to ONE WATT only.
iii)The hand held transceiver must be identified by the call sign of the ship station along with its
associated unit designator.
b)Portable Ship Station: The Commission may grant a station license permitting operation of a
portable ship station aboard different vessels of the United States. Each application (FCC
Form 506-Application for a Ship Radio Station License) for a portable ship station license must
include a showing that:
i)The station will be operated aboard a vessel.
ii)A station license for portable equipment is necessary to eliminate separate applications to
operate a ship station aboard different vessels.
c)Marine Utility Station: A utility station in the maritime mobile service consists of one or more
hand held transceiver units licensed under a single authorization. Each unit is capable of
operating while being hand carried by an individual. There are two types of stations authorized:
i)Marine Utility Coast-when transmitters are located on land; may communicate directly to
vessels only.
ii)Marine Utility Coast/Ship-transmitters from land may communicate with vessels or when
aboard a vessel, may communicate with other vessels or coast stations.
NOTE: A Marine Utility Ship license will not be authorized.
The station operates under the rules applicable to a private coast station when the unit (s) are
on land and under the rules applicable to a ship station when the unit (s) are aboard a vessel.
FCC Form 503, application for Land Radio Station License is used when applying for a marine
utility License.
USAGE GUIDE
Emergency Calling Monitoring Intership Safety U.S. Coast Guard Navigation Port Operations
Noncommercial Commercial Marine Operator State Control Environmental Weather
Emergency
Channel 16
If:
Your ship is sinking, or on fire
Someone has been lost overboard
There exists grave and imminent danger
Use this distress procedure:
Select Channel 16
Say "Mayday, Mayday, Mayday."
Give call sign and boat name
Give location of boat
Describe emergency
If no answer, repeat; then try and other channel
Caution:
Ever ship at sea is obliged to give absolute priority to radio communications relating to ships
distress-it is vital that false distress calls or messages not be broadcast.
Calling
Channel 16 & Working Channel
If-you wish to establish communications with another station
And-you know which working channel the station is monitoring
Then-initiate the call directly on that working channel
If-you wish to establish communications with another station
And-you do not know what working channel the station may be monitoring
Then-initiate the call on channel 16. After contact is made switch to a working channel.
NOTE: Due to congestion on channel 16 caused by frequent hailing of other vessels, the FCC
has approved channel 9 as a second hailing channel.
Avoid excessive calling and radio checks
Always monitor before transmitting
Never interrupt emergency communications
Monitoring
Channel 16 & working Channel
When-your VHF station is turned on and it is not being used to exchange communications
You Must-monitor channel 16
As an operating convenience, many stations employ a second receiver so that they can
monitor a working channel and channel 16 simultaneously.
