                           Revision 3.0 August 25,1992


     To all of my friends that I have spoken with throughout the world, I
give you the final version of the DJ-580 handheld radio "Users Manual".
I have sifted through this manual once again and restructured some areas while
improving the index. You now have in your hands a manual that took over 250 
hours to prepare and maintain. This does not include the hundreds of telephone 
calls that I have taken collectively either at home or at work. I dedicate 
this manual to those amateurs who have spent long and endless hours trying to 
understand what their radio does. I would like to thank ALINCO ELECTRONICS for 
their support. Without this support there would be no manual. Finally, I would 
like to thank my family for their endless patience during this project.

                                   Page 5

          1. Press and hold the FUNC key, then press the SHIFT key
             repeatedly until the desired shift appears on the LCD display.

               The - symbol indicates that the transmitter will subtract
                the offset with the transmitted frequency.

                The + symbol indicates that the transmitter will add the
                offset with the transmitted frequency.

                The star symbol indicates a split offset. Refer to Section
                9.1 for more information.

                Simplex operation is active when neither the - or + or star
                symbol is displayed on the LCD display. If OFF appears in
                place of the frequency during transmit, the selected
                frequency is out-of-band.

          2. Select the Active Band by pressing the VHF or UHF key. The LCD
             display returns to frequency.

                                   *** NOTE ***

             For larger incremental frequency changes press and hold the
             FUNC key then rotate the Main Tuning dial. This increments the
             1MHZ digit. 

             Amateur radio repeaters utilize separate transmitter and
             receiver sections. The transmitter frequency may be offset
             either above or below the receive frequency according to
             repeater coordination conventions. The standard offset for the
             2 meter band is 600 Khz. Offset for the 70cm band is 5 Mhz.
             Offset direction varies according to established band
             plans.

             EXAMPLE: SHIFT

             1. Select the Active Band by pressing the VHF or UHF key.

             2. Press and hold the FUNC key, then press the SHIFT key. An

                              *** WARNING ***

             It is possible to cause UHF receive interference while
             transmitting on VHF. To avoid this from happening, make sure
             that the VHF frequency x 3 does not equal the frequency on
             UHF. For example, if VHF transmit frequency is 146.190 the UHF
             frequency should not be set at 438.570.

 3.1.12 T.SQL KEY

        The Tone Encoder and Tone (Decoder) Squelch function is standard on
        the DJ-580T/E. Tone Encode and Decode works on the Active Band
        only. In other words, it is expected that you can only speak on one
        band at a time. When changing over to the other band, another tone
        may be used. Further clarification is made in the cross band repeat
        section. The DJ-580T/E has 38 settings from 67.0 hz to 250.3 hz
        (TABLE 3). Utilize the TONE key to access these settings. Access to
        an increasing number of repeaters is restricted by requiring that a
        sub-audible tone be transmitted with the input signal to open the
        repeater. In the following examples, it is presumed that you are
        learning how to operate the Tone Encode/Decoder for the first time.

                                  Page 24

             You can scan the memory channels with the SCN key, elect to
             skip any memory channel with the SKIP key, or select the scan
             type with the TMS key. Refer to the section SCANNING FUNCTIONS
             (Section 8) for more information.

             The DJ-580T/E has two (02) banks of memory channels:

             First, the VHF bank has 20 memory channels that are accessed
             with the MR key.

             Secondly, the UHF bank has 20 memory channels that are
             accessed with the MR key.

 6.2.3  CANCELING A MEMORY CHANNEL

          1. Select the Active Band by pressing the VHF or UHF key.

          2. Press the MR key. 

          3. Rotate the Main Tuning Dial to choose the desired memory
             channel number (clockwise to increase, counter clockwise to
             decrease). Select a non-flashing memory channel number.

          The number of memory channels will change if you have utilized
          the ALLOCATION OF MEMORY CHANNELS feature. The radio defaults
          it's memory channels from 0 to 19 on VHF and 0 to 19 on UHF.

          4. Press and hold the FUNC key, then press the MW key to cancel
             this memory channel. The two digit memory channel number will
             now begin to flash indicating that the content of this memory
             channel has been cleared.

 6.2.4  ALLOCATION OF MEMORY CHANNELS

        Using this feature will allow you to free up memory channels from
        either band and allocate to the other band for frequency storage. 

        EXAMPLE: ALLOCATE MEMORY CHANNELS

        Lets say you wish that you had 25 programmable VHF memory channels
        but the radio comes defaulted to 20. No problem, that's why this
        feature has been included. Since the radio has 40 channels in
        total, 20 for each VFO, it is possible to allocate all 40 channels
        to one band for memory programming. This scenario would leave the
        other band with no programmable memory channels. Here is how to
        make it all happen.

          1. Press and hold the FUNC key, then press the * key. The symbol
             FL will appear on the LCD display.

          2. Press and hold the FUNC key, then press the 1 key. The number
             of allocated memory channels for each VFO will appear on each
             band display.

             When the Main Tuning Dial is rotated clockwise, the number of
             possible VHF memory channels will increase. This number will
             increase while the allocated memory channels from the UHF side
             will decrease. 
                                  Page 25

             When the Main Tuning Dial is rotated counter clockwise, the
             number of possible UHF memory channels will increase. This
             number will increase while the allocated memory channels from
             the VHF side will decrease.

          3. Press and hold the FUNC key, then press the * key four (4)
             times to clear FL/PL from the display and exit beep tone level
             mode.

 8      SCANNING FUNCTIONS

        The DJ-580T/E offers various scanning options and 3 scanning modes
        described a little later on in this section. First lets look at the
        scanning options, they are:

        VFO Scan                      - Scans either band           
                                        independently.

        Program Band Scan (VFO Mode)  - Scans programmed lower to
                                        upper frequencies. You may scan a   
                                        range of frequencies.

        Memory Scan                   - Each band may scan memory
                                        channels independently.

        Whether you are scanning (SCN) or manually tuning, when;

             o  Passing a 500KHz boundary a single beep will be heard
                through the speaker. 

                                  Page 30

             o  Incrementing frequencies past a 1MHz boundary, a low beep
                followed by a high beep will be heard. 

             o  Decrementing frequencies past a 1MHz boundary, a high beep
                followed by a low beep will be heard.

 8.1    VFO SCAN

        Each band may scan VFO channels independently. When in Band Scan
        mode the DJ-580T/E scans by channel Step. Refer to Section 3.1.7 
        for more information on the channel Step key. As the scan passes
        through any 500 KHz or 1 MHz point a tone will sound if the BEEP
        function is active.

          1. Select the Active Band by pressing the VHF or UHF key twice.
             The purpose for pressing the band key twice is in the event
             you are in memory mode by mistake.

          2. Press the SCN key for approximately 1 second, a beep will be
             heard. Release the SCN key. Use the Main Tuning dial or UP
             ARROW or DOWN ARROW keys to scan in a particular direction.

          3. Whether you are cycling upward or downward, during scan the
             decimal point will flash indicating that scanning has begun.

          4. When a signal is received, scanning will stop and remain on
             that frequency. When channel goes quiet or Main Tuning Dial is
             rotated clockwise or counter clockwise, scanning will
             continue.

          5. To cancel scanning press the SCN key. A beep will not be heard
             when initially pressed, but will be heard when the SCN key is
             released.

             All 3 scan types can be applied to Band Scan.

 8.1.1  PROGRAM BAND SCAN MODE (VFO MODE)

        This scan option allows the scanning of a range of VFO frequencies.
        Each band may have independent scan ranges. The lower band limit is
        programmed into Memory Channel P1. The upper band limit is
        programmed into Memory Channel P2. You may initiate Program Band
        Scan from either VFO or Memory mode.

        EXAMPLE: STORING LOWER/UPPER RANGES

          1. Select the Active Band by pressing the VHF or UHF key, for
             example VHF.

             the selected Upper Frequency into memory.

         10. Press and hold the FUNC key, then press the SCN key. The
             letter P will begin to blink on the display. Scanning from
             146.000 to 146.100 has begun. 

         11. Press the Active Band key as performed in step 1 to stop this
             function. Pressing the SCN key will also cease this function.

                               *** NOTE ***

             The upper limit frequency and Lower limit frequency may be
             stored into either P1 or P2.

 8.2    MEMORY SCAN MODE

        This scan option allows the user to scan frequencies that have been
        programmed in any (or all) of the memory channels. Bands may be
        scanned individually or both bands may be scanned simultaneously.

          1. Select the Active Band by pressing the VHF or UHF key twice.
             The purpose for pressing the band key twice is in the event
             you are in memory mode by mistake.

          2. Press the MR key.

          3. Press the SCN key for approximately 1 second, a beep will be
             heard. Release the SCN key. Use the Main Tuning dial or UP
             ARROW or DOWN ARROW keys to scan in a particular direction.

          4. Whether you are cycling upward or downward, during scan the
             decimal point will flash indicating that scanning has begun.

          5. When a signal is received, scanning will stop and remain on
             that frequency. When channel goes quiet or Main Tuning dial is
             rotated clockwise or counter clockwise, scanning will
             continue.

          6. Press the Active Band as performed in step 1 to stop this
             function. To cancel scanning press the SCN key. A beep will
             not be heard when initially pressed, but will be heard when
             the SCN key is released.






                                  Page 32

 8.2.1  MEMORY CHANNEL SKIP MODE

        Memory Channel Skip permits unwanted memory channels to be skipped
        during memory scan. This step presumes that you have already
        programmed some/all memory channels.

          1. Press the MR key.

          2. Rotate the Main Tuning Dial until the memory channel that you
             want to skip is displayed.

          3. Press the SKIP key. The decimal point will disappear from the
             frequency displayed, indicating this frequency will be
             skipped. Perform step 2 and 3 for each memory channel that you
             wish to skip.

          4. To cancel Memory Channel Skip, press the SKIP key again. The
             decimal point will re-appear, and that memory channel will now
             be restored to scan status.

 8.3    SCANNING TYPES

        The DJ-580T/E offers 3 different scanning modes as shown below. The
        initial factory setting is the Busy Channel Scan.

        Busy Scan  - Stops at a busy channel or frequency until
                     clear. Two seconds after the signal ceases, scanning   
                     resumes.

        Timed Scan - Stops at busy channel or frequency, then
                     resumes scan 5 seconds later even if the
                     channel remains busy. Scanning will also
                     resume when a signal received ceases.

        Selecting a Scan Type:

          1. Select the Active Band by pressing the VHF or UHF key.

          2. Press and hold the FUNC key, then press the TMS key. A black
             block with a white lettered T will appear, indicating to you
             that "Timed Scan" has been selected.

          3. Press and hold the FUNC key, then press the TMS key again to
             leave "Timed Scan". The black block with a white lettered T
             will disappear from the LCD display.

          The DJ-580 will be in "Busy Scan" when not in "Timed Scan".

 8.4    OTHER SCANNING INFORMATION

        This subsection talks about all other information pertinent to
        radio scan.

 9      REPEATER OPERATIONS

        Amateur radio repeaters utilize separate transmitter and receiver
        sections. The transmitter frequency may be offset either above or
        below the receive frequency according to repeater coordination
        conventions. 

 9.1    SPLIT FREQUENCY FUNCTION

        When standard offsets will not satisfy an input or output
        frequency, a split is utilized for this purpose. Split can be
        configured on the DJ-580 for VFO and MEMORY modes. The split
        frequency function will not operate in CALL mode.

 9.1.1  VFO MODE SPLIT

        Perform the following for VFO MODE SPLIT.


                                  Page 34

          1. Select the Active Band (VFO) by pressing the VHF or UHF key.
             Enter a frequency into the VFO for your output (receive)
             frequency.

          2. Press the MR key. Program or select a frequency in any MEMORY
             channel for your input (transmit) frequency.

          3. Enter VFO as selected in step 1. VFO frequency is used for
             receive and the MEMORY channel is used for transmit. 

          4. Press and hold the FUNC key, then press the SHIFT key
             repeatedly until the star symbol appears on the display. The
             split setup is now complete.

 9.1.2  MEMORY MODE SPLIT

        Perform the following for MEMORY MODE SPLIT.

          1. Press the MR key. Program or select a frequency in any MEMORY
             channel for your input (transmit) frequency.

          2. Select the Active Band (VFO) by pressing the VHF or UHF key.
             Enter a frequency into a VFO for your output (receive)
             frequency.

          3. Press the MR key again. The MR frequency is used for receive
             and the VFO frequency is used for transmit. 

          4. Press and hold the FUNC key, then press the SHIFT key
             repeatedly until the star symbol appears on the display. The
             split setup is now complete.

 9.2    REV KEY

        In some areas there may be repeaters operating on repeater
        frequency pairs, the exact reverse of another repeater in the area.
        That is, the input of one repeater is the output frequency of the
        other and vice versa. To avoid the inconvenience of reprogramming
        every time both repeaters are in range, the REV key allows instant
        reversal of the input and output frequencies and the offset
        direction. The REV function is also useful to check the repeater
        input to determine if another station is heard directly so you can
        go simplex. To activate the REV function:

             1. Press and hold the FUNC key, then press the REV key. The
                repeater input frequency and opposite SHIFT indicator will
                appear on the LCD display panel.

             2. Press and hold the FUNC key, then press the REV key again
                to cancel the REV function.

 9.3    RESETTING RADIO

                                  *** NOTE ***

          Resetting the radio will erase all user programmed information
          (frequencies,shifts,offsets etc.) Make sure that this information

                                  Page 35

          has been written down before proceeding.

          1. Make sure radio is powered off.

          2. Press and hold the FUNC key in while turning on the radio via
             the power knob. The LCD will display 145.00 (VHF) and 445.00
             (UHF).
                               *** NOTE ***

          If you were to hold the func key in and not let it go while
          powering up the radio, all display segments will be shown.

 9.4    CTCSS ENCODE/DECODE

        CTCSS encoding allows you to select the proper tone frequency to
        open another operators radio receiver or repeater. CTCSS decoding
        enables another operator to select the tone your receiver requires
        enabling you to hear them. Unlike Code Squelch operation (Refer to
        section 11 for details), a specific tone frequency is used. Here's
        how to use CTCSS Encoding/Decoding.

          1. Select the Active Band by pressing the VHF or UHF key.

          2. Press and hold the FUNC key, then press the TONE key. 

          3. Rotate the Main Tuning dial to the desired tone.

          4. When the tone has been selected enter the Active Band by
             pressing either the VHF or UHF key.

          5. Press and hold the FUNC key, press the T.SQL key repeatedly.
             Tone settings will cycle each time the T.SQL key is pressed.
             It cycles as follows on the LCD display:

             o  The Tone Encoder is Enabled when the letter T is displayed
                on LCD.

             o  The Tone Decoder Squelch function is enabled when the
                letter T and SQL is displayed on the LCD. When this
                function is active, you would expect a particular tone to
                open your radio receiver.

             o  When the T and SQL is not displayed, the encoder/decoder is
                disabled.

             EXAMPLE: TONE ENCODER/DECODER 

                Radio for Joe              Radio for Linda
                -------------              ---------------
                Tone set: 100.0            Tone set: 100.0              
                T displayed (ENCODE)       T and SQL displayed (DECODE)

             A) Radio operator "Joe" is calling "Linda". The interesting
                point here is that when the radio that Linda is using
                displays T and SQL, nothing will be heard through her
                radio speaker when squelch is opened up (fully counter


                                  Page 36

                clockwise). You will notice however that the S/RF
                indicator will be shown on the LCD when squelch is
                opened.

             B) The only way that Linda will hear Joe is for Joe to send
                the proper tone to open Linda's radio receiver. If Joe
                doesn't send the right tone, Linda's radio will remain
                silent.

10      AUTOPATCH OPERATION (AUTOMATIC DIALER)

        The DJ-580T/E offers three automatic dialer memories. A telephone
        number may be entered in either the VHF or the UHF frequency mode.
        The stored telephone number is transmitted on whichever band is
        selected as the Active Band.
        
10.1    PROGRAM AUTODIAL NUMBER

        To enter a telephone number, perform the following:

          1. Press and hold the FUNC key, then press the A key. The
             selected VFO frequency display will clear and display C1 or C2
             or C3. Rotate the Main Tuning dial clockwise or counter-
             clockwise to obtain a desired dialer memory. The telephone
             symbol will display on the LCD and flash, indicating that the
             dialer memory is ready to accept the number to be stored. You
             may enter up to 16 numbers, letters and symbols, four at a
             time in four groups.

          2. The telephone number or codes should be entered in order from
             the beginning. The following characters can be used:
                              0-9, A-D, *, #

          3. Press and hold the FUNC key, then press the A key to store the
             entered telephone number or codes. The telephone symbol stops
             flashing and is on steady to show that this function is
             active.

             Proceed to Section 10, 10.4 to transmit the dial sequence.
             Clear out dialer memory to enter a new sequence. 

10.2    CLEAR DIALER MEMORY

          1. Press and hold the FUNC key, then press the A key.

          2. Rotate the Main Tuning dial to the dialer memory you wish to
             make a correction in.

                                  Page 37

          3. Press and hold the FUNC key, then rotate the Main Tuning dial
             until the sequence of digits you wish to correct have just
             exited the display. 

          EXAMPLE: CORRECTING DIALER CODES

             Programmed number is 123567890, but you forgot 4!

          1. Press and hold the FUNC key, then press the A key.

          2. Rotate the Main Tuning dial to the dialer memory you wish to
             make a correction in.

          3. Press and hold the FUNC key, then rotate the Main Tuning until
             the numeral 3 is displayed.

                This represents the last digit displayed on the LCD.   
                | These digits are hidden just right of last digit shown.
                v vvvvvv 
              123 567890

          4. Now enter 4567890. After you play with this for awhile you
             will see how it works. 

10.4    TRANSMIT/CHANGE AUTODIAL NUMBER

        After performing the steps in section 10.1, perform the following
        steps to transmit the programmed number.

          1. Press and hold the FUNC key, then press the "A" key.

          2. The telephone symbol could be blinking which represents an
             unprogrammed dialer memory channel. Refer to Section 10.
             Otherwise, rotate the main tuning knob to the desired dialer
             memory channel.

             Verify that the blinking telephone symbol appears on the LCD
             display.

          3. Press the PTT switch for an instant. This will return you to
             VFO mode.

          4. To transmit dialer memory channel, Press and hold the PTT key.

                            ** LOOK AT LCD DISPLAY ** 
  
             You are now transmitting. The ON AIR symbol should display on
             the LCD display.  

          5. While transmitting press the FUNC key to send/transmit the
             autodial sequence.
                                   ** LISTEN ** 
  
             The dialer sequence that you programmed earlier will be
             transmitted. You can hear the tones that are being sent
             through the DJ-580 speaker.


                                  Page 38

                               HIDDEN FUNCTIONALITY

             This is where you will have to experiment a bit. You can
             change the dialer sequence timing. Refer to Section 10.7 for
             all of these new details.

10.5    MANUAL DIAL

        In some instances you may want to dial a number manually. perform
        the following steps.

          1. The telephone symbol should not appear on your display. If it
             does, press and hold the FUNC key, then press the A key, the C
             key and finally the A key again.

          2. Press and hold the PTT key.

          3. Now dial the number on your keypad as you would a telephone.

10.6    DISABLE AUTODIAL

        Performing the following step will erase a stored number in the
        autodialer.

          1. Press and hold the FUNC key, then press the A key, the C key
             and finally the A key again. 

          You can either clear the dialer channel or not press the FUNC key
          during a transmission. 

10.7    DIALER RATE ADJUST

        The following steps are used for changing the dialer and DSQ tone
        rates. This function may not appear/be available on earlier DJ-580
        units.

          1. Press the * key. The symbol FL will appear on the LCD display.

          2. Press the following keys in sequence: #, 1, 2, 3. The LCD will
             display the letter C. If you repeat this step continuously the
             letters will change as follows:

                  C,D,upside down A,H,0,1,2,3,4,5,6,7,8,9,A,B

          Each of these indicators are associated with a different rate
          during transmission. The fastest begins at 1 and the slowest is
          zero. The letters are variations of slow rates.

11      DIGITAL SQUELCH (DSQ) 

        DSQ stands for DTMF Squelch Control. DSQ is very versatile and will
        allow you to:

          o  Make a transmission that will specifically be heard by a
             particular group (of your choosing, by a code sequence).
          o  Place a private call to a selected person in a group.
          o  Call a single operator.
          o  Straight DSQ transmission

        This feature is achieved by use of DTMF Tones that will either open
        (or keep closed) the DJ-580T/E. In this section you will learn how
        to transmit and receive the DSQ SCHEME! A radio must be DSQ
        compatible to take advantage of these features.

11.1    DSQ SCHEME

        Before we get started let's look at the DSQ tone structure.
        Depending on the transmission type (Group, Private etc.), a
        particular tone sequence will be sent. The tone structure is broken
        down into the following areas:

          o  GROUP Code - 3 digit sequence
          o  OTHER'S Code - 3 digit sequence
          o  OWN Code - 3 digit sequence
          o  MISC Codes

        The following explanation of each area will help you to fully
        understand how each is utilized.

        3 DIGIT "GROUP" CODE 
 
        By programming a 3 digit group code your members of a group would
        receive a common transmission. Perhaps this group wouldn't want to
        hear a transmission meant for another group that has another 3
        digit code sequence. 

        EXAMPLE: GROUP CODE 
 
        Lets say that you are helping the local police department find a
        missing child. They have split 10 radio operators
        into 2-five person teams. Let's call them team 1 and team 2. 

        Each member of team 1 has a radio with a group code of 111. 
        Each member of team 2 has a radio with a group code of 222. 
 
        The police have just found evidence that the child is definitely
        located in team 2 territory. The central transmission point now
        needs to contact the members of team 1 and notify them that their
        search area must be changed. They will send out a 111 group code
        (tone sequence) to team 1. By virtue of the group code 111, all
        members of team 1 will hear the message and team 2 will hear
        nothing on their radios. A separate transmission to group 2 could
        be placed with specific updated information!



                                  Page 40

        3 DIGIT "OTHER'S" CODE 
 
        This code is used as an identifier of another station. In other
        words, it is the other persons "own" code.  

        EXAMPLE: OTHERS CODE 

        Lets say that an individual in team 1 needs to be given some
        specific information. The receiving stations identifier is referred
        to as the other's code. We will send that person the information by
        virtue of their 3 digit "own" code. You must enter their "own" code
        into your "others" code field.  

        3 DIGIT "OWN" CODE 
 
        A transmitting station uses 3 digits as a personal identification
        number. A receiving station uses this code to identify who called
        them.  

        EXAMPLE: OWN CODE

        Lets say that you will receive some specific information. The other
        person will need to know your "own" code before your radio will
        receive a private call. Your "own" code is also  necessary, because
        the other person receiving your message will see your "own" code
        displayed on their radio LCD.

        MISC CODES

        16 numbers, letters and symbols can be used for coding. Here's what
        you can use; 0-9, A-D, * and #. An "H" will appear on the LCD when
        the * is entered and upside down A will appear when the # is
        entered. The # sign is used as a wild card. Refer to WILDCARD for
        more information. 

11.2    PROGRAMMING ALL DSQ CODES

        Place your radio in front of you. The following steps get your
        radio set for DSQ operation.

          1. Select the Active Band by pressing the VHF or UHF key.

          2. Press and hold the FUNC key, then press the B key. The LCD
             display will indicate A-000.

          3. Enter 3 digits for the group that YOU want to call. In other
             words, a unique calling code for a specific group.

             EXAMPLE: PROGRAM 1ST GROUP CODE

                                   A-123

          4. Rotate the Main Tuning dial clockwise until B-000 is displayed
             on the LCD.

          5. Enter 3 digits for another group that YOU might call. This is
             an additional group calling code.

                                  Page 41

             EXAMPLE: PROGRAM 2ND GROUP CODE

                                   B-456

          6. Rotate the Main Tuning dial clockwise until P-000 is displayed
             on the LCD.

          7. Enter 3 digits for your "own" Personal code. This is your
             unique identification code.

             EXAMPLE: PROGRAM YOUR OWN CODE

                                   P-100

          8. Rotate the Main Tuning dial clockwise until y-000 is displayed
             on the LCD.

          9. And now you must select the "others" 3 digit code. This is the
             operator you're calling. Lets say you're calling operator 200,
             enter "200" on the keypad. 

             EXAMPLE: PROGRAM THE OTHERS CODE

                                   y-200

         10. Rotate the Main Tuning dial clockwise until nn-00 is displayed
             on the LCD.

         11. Enter a two digit code that will become the Digital Signal
             Message.

             EXAMPLE: DIGITAL SIGNAL MESSAGE

                                   nn-07

         12. Press the VHF or UHF key to end setup.

             Only radios with DSQ functionality are capable of receiving
             and/or transmitting DSQ tasks. These tasks are described in
             the following sub-sections, have fun!

11.3    DSQ MODES

        This section will address all functions of DSQ and describe how
        they should be used. Only through experimentation of DSQ will you
        get the hang of it. DSQ functionality comes in various flavors, and
        they are shown in the following table.

                     DSQ FUNCTION               LCD DISPLAY
             -----------------------------   -----------------
                     Straight DSQ                    D.SQ  
                     Group Calling               G   D.SQ
               Private Calling In A Group        G P D.SQ
                     Private Call                  P D.SQ




                                  Page 42

11.3.1  TRANSMITTING (CODE SQUELCH)

        Coded Squelch is a unique 3 digit sequence, when sent to another
        unit configured only for D.SQ, will open the receiver for
        reception. It's always a good idea to have a cheat card that lists
        each units identifier (own code) and group codes.

          1. Select the Active Band by pressing the VHF or UHF key.

          2. Press and hold the FUNC key, then press the B key.

          3. Rotate the Main Tuning dial and select either A- for GROUP A
             or B- for GROUP B. Each group should have a unique identifier
             code. If either GROUP A or B doesn't contain the desired 3
             digit code, enter it in at this time via the keypad.

          4. Return to the Active Band as selected in step 1.

          5. Press the B key several times until "D.SQ" displays on the
             upper right-hand corner of the LCD. 

          6. When you press the PTT key, the Code Squelch is transmitted
             automatically. At the conclusion of the 3 digits being
             transmitted, the operators radio (who you are calling)
             receiver will accept your transmission.

11.3.2  RECEIVING (CODE SQUELCH)

        If the received Code Squelch signal matches the set Code Squelch
        code, D.SQ will begin to flash on the LCD display. In addition, an
        audible alert will be heard through the speaker.

        If the receiver is on receive mode by code squelch, it is possible
        to communicate within 1.5 seconds after a received signal is
        clipped.

11.3.3  TRANSMITTING (GROUP CALLING)

        When you select this option, you will be able to contact many
        operators that collectively make up a group. If operators with
        compatible DSQ functionality are configured correctly, and all have
        the same group code programmed, their radios should open and
        receive your call. It's always a good idea to have a cheat card
        that lists each units identifier (own code) and group codes. Here's
        what you have to do.

          1. Press the B key. 

          2. Rotate the Main Tuning dial and select either A- for GROUP A
             or B- for GROUP B. Each group should have a unique identifier
             code.

          3. Press the B key several times until G D.SQ displays on the
             upper right-hand corner of the LCD. 

          4. When you press the PTT switch, the GROUP code selected will be
             transmitted to all units in the GROUP.

                                  Page 43

             If you are using GROUP A in step 2 and wish to change to GROUP
             B, follow steps 1-4 again.

             The following DSQ code is transmitted as shown:

                 (3 DIGIT GROUP CODE) * (3 DIGIT OWN CODE)

11.3.4  RECEIVING (GROUP CALLING)

        To receive DSQ coded calls in GROUP CALLING, setup your radio for G
        DSQ as follows:

          1. Press and hold the FUNC key, then press the B key until G DSQ
             appears on the LCD display.

        When the received DSQ code matches the first 3 digits of your
        display (group code), the G DSQ indicator will begin to flash. If
        the BEEP is off, the squelch will open for as long as the calling
        operator is transmitting. If the BEEP is on, an audible beep will
        be emitted from the radio and the indicator will display which
        group is calling. Reset the display by pressing the Active Band key
        or PTT.

11.3.5  TRANSMITTING (PRIVATE CALLING IN A GROUP)

        It's always a good idea to have a cheat card that lists each units
        identifier (own code) and group codes.

          1. Press the B key. 

          2. Rotate the Main Tuning dial and select either A- for GROUP A
             or B- for GROUP B. Each group should have a unique identifier
             code.

          3. Press the B key several times until GPDSQ displays on the
             upper right-hand corner of the LCD. 

          4. Press the PTT switch to transmit the DSQ code or press the VFO
             key for the band you are working.

          The following DSQ code is transmitted as shown:

          (3 DIGIT GROUP CODE) (1 DIGIT OTHERS CODE) * (1 DIGIT OWN CODE)

11.3.6  RECEIVING (PRIVATE CALLING IN A GROUP)

        To receive DSQ coded calls in PRIVATE CALL IN A GROUP, setup your
        radio for GPDSQ as follows:

          1. Press the B key until GPD.SQ appears on the LCD display.

        When the received DSQ code matches the first 3 digits of your group
        and your own code, the DSQ GP indicator will begin to flash. If the
        BEEP is off, the squelch will open for as long as the calling
        operator is transmitting. If the BEEP is on, an audible beep will



                                  Page 44

        be emitted from the radio and the indicator will display which
        group is calling. Reset the display by pressing the Active Band key
        or PTT.

11.3.7  TRANSMITTING (PRIVATE CALL)

        This option would be used when someone is calling only you. This is
        different from encode/decode because you determine your own
        identification code and not a subaudible tone. It's always a good
        idea to have a cheat card that lists each units identifier (own
        code) and group codes.

          1. Press the B key. 

          2. Press the B key several times until P D.SQ displays on the
             upper right-hand corner of the LCD. 

          3. Press the PTT key to transmit the DSQ code or press the VFO
             key for the band you are working.

          The following DSQ code is transmitted as shown:

                (3 DIGIT OTHERS CODE) * (3 DIGIT OWN CODE)

11.3.8  RECEIVING (PRIVATE CALL)

        To receive DSQ coded calls in PRIVATE CALL, setup your radio for P
        D.SQ as follows:

          1. Press and hold the FUNC key, then press the B key until P D.SQ
             appears on the LCD display.

11.4    ERROR CODE

        When the "Other's" private code is not confirmed the LCD display
        will indicate "Er".

11.5    TIMING CONSIDERATIONS

        On occasions you may find that the operation of DSQ through some
        older repeaters may be unpredictable. This occurs on initial
        transmit with your DJ-580. When you transmit, a time delay occurs
        before the repeater is fully transmitting. The DJ-580 will begin to
        transmit the DSQ tone sequence during the repeater transmit delay.
        The DJ-580 can delay 450 ms or 750 ms. In addition, the timing
        period for the tone burst sequence can be adjusted. Please refer to
        section 10.7 for more information.
 
        It is possible to delay the time to transmit codes to about 750ms
        after the PTT key is pressed.

          1. Press and hold the FUNC key, then press the * key. The LCD
             display will display FL.

          2. Press and hold the FUNC key, then press the 4 key. The LCD
             display will display d-750 or d-450. Repeat this step until
             the desired selection is made.

                                  Page 45

          3. Press and hold the FUNC key, then press the * key. Repeat this
             step until FL and PL is absent from the display.
        
11.6    DSQ WILDCARDS 

        The # symbol is a wildcard that may be substituted for any one
        digit,letter or symbols used in DSQ codes. When the # symbol is
        entered it appears on the LCD display as an upside down A. The
        wildcard allows for the combination of many groups. If the first or
        first and second digits of several group codes are the same, you
        can replace the second and third digits (or just third digit) with
        a # mark, and thus transmit to all those groups.

        EXAMPLE: WILDCARDS 

          1. Enter the 2 meter frequency of 146.520.

          2. Press and hold the FUNC key, then press the DSQS key. Select
             any code squelch memory channel.

          3. Release the FUNC key now and select a 3 digit code squelch
             code using the keypad.

             Example: Enter the 3 digit code 1#5.

          4. Press the FUNC key to return the LCD display to operating
             frequency.

             Example: Now you will see on the LCD display P45.52. 

          5. Press the D.SQL key repeatedly (2 times) until C appears in
             the 100 MHz digit location.

             Example:   C45.620

          If the incoming coded calls are anyone with a group code as
          follows, the call will be received by your radio.

             o  105 through 195
             o  1A5 through 1D5
             o  1*5
             o  1#5

          6. When you receive a call from another station, the C will flash
             on and off for as long as the other operator is transmitting.
             Your radio has already memorized who was calling you, so press
             the PTT switch and you will transmit to that station directly.
             When you have completed your QSO, enter the wildcard sequence
             again to open your radio to all other stations again.

11.7    DIGITAL SIGNAL MESSAGE

        This function allows you to send or receive messages consisting of
        2 digit codes.




                                  Page 46

11.7.1  TRANSMITTING DIGITAL SIGNAL MESSAGE

        You can retain 1 signal message in the transmitter memory.

          1. Press and hold the FUNC key, then press the B key.

          2. Rotate the Main Tuning dial and select a message memory
             channel nn.

          3. Enter a 2 digit message code. This is a code that has been
             predetermined and understood by the operating parties.

          4. Press the VHF or UHF key to end setup.

          5. Set the appropriate paging function (D.SQ, G D.SQ etc).

          6. Press the PTT key to transmit the DSQ code. Continue to hold
             the PTT key and press the CALL key. 

             What the receiving operator will see on the display will be
             the unit number f the calling station followed by the 2 digit
             code. The following is the sequence sent:

                        # (2 DIGIT SIGNAL MESSAGE)

11.7.2  RECEIVING DIGITAL SIGNAL MESSAGE

          1. Set the appropriate paging function (D.SQ, G D.SQ etc).

          2. When the appropriate codes are received, your receiver will
             open to hear the calling operator. When the digital signal
             message is sent shortly after the initial transmission, you
             will see on the LCD display the 3 digit calling station
             followed by a - and then the 2 digit digital signal message.

11.7.3  TRANSMITTING WITH DIGITAL SIGNAL DISPLAYED

        While a digital signal message is displayed, press the PTT switch.
        Your signal will be transmitted back to the station calling by
        using the displayed DSQ settings. The frequency will return to your
        LCD display.

11.7.4  REVIEW DIGITAL SIGNAL MESSAGE MEMORY

        You can store up to 3 previously received digital signal messages.
        The first two memories store the messages in received order. The
        third memory stores the latest message. These messages display the
        3 digit calling station followed by the 2 digit message. Here's how
        to view digital signal message memory.

          1. Press and hold the FUNC key, then press the MESS key. Select
             any code squelch memory channel. The latest message will be
             displayed on the LCD display.

          2. Rotate the Main Tuning dial to review the previously sent
             messages in n1 through n2. You can also use the arrow keys to
             review these messages.

                                  Page 47

11.7.5  CLEARING MESSAGE MEMORY

        If you find it necessary to clear out messages, proceed with the
        following steps.

          1. Select the memory number and press the C key once to clear out
             that location.

12      CROSS BAND REPEATER 

        The DJ-580 is capable of cross band repeat. To simplify matters, it
        means that when you transmit on one band it is simultaneously heard
        on the other band. Ok you want to set up a cross band repeater?
        Here are a few things to remember about cross band repeat:

          1. When cross band repeat is active, you cannot change
             frequencies or utilize other functions with the exception of
             cross band deactivation.

          2. Set squelch threshold before you activate cross band repeat.

          3. No radio modification is necessary to activate this function.

          4. This isn't a 100% duty cycle repeater. If the radio becomes
             extremely hot to the touch, the radio should be allowed a cool
             down time.

          5. Use cross band repeat in either Low or Mid power only.  

          6. Cross band repeat will not allow for different CTCSS
                Encode/Decode tones on each band.

             Using cross band repeat allows a user to enter on one band and
             cross over to the other band. You may use shifts or operate in
             simplex operation. 

12.1    ACTIVATE CROSS BAND REPEATER

        Here are the steps for cross band repeat.

          1. Rotate the volume controls for the VHF and UHF bands fully
             counter-clockwise.

          2. Press and hold the FUNC key, then press the FL key. The LCD
             should display FL. 

          3. Press each key once as follows: #, 5, 0 and 8. You should
             notice that the word oPEn displays on the LCD and the opposite
             band indicator will begin to blink. The radio is now in cross
             band repeat. When a signal is received on one band, it will be
             retransmitted onto the other band.









                                  Page 48

12.2    DEACTIVATE CROSS BAND REPEATER

        To return to original mode perform the following:

          1. Press and hold the FUNC key, then you will press the FL/PL key
             4 times. After you press it the first time the LCD will
             display CLoSE. This indicates to you that cross band repeat
             has been disabled. The other 3 times that you press the FL/PL
             key will turn off the FL and PL indicators.  

13      FULL DUPLEX OPERATION

        The principles of Full Duplex operation is very much like a
        telephone. The idea behind this is that when you are talking (let's
        say) on 2 meters you will hear the transmission from the other
        station on the 440 band. He will hear you on 2 meters.
        
        YOUR STATION                                  OTHER STATION

        TRANSMIT ON 2 METERS ------>-------->-------> RECEIVE ON 2 METERS
        RECEIVE ON 440 BAND  <-----<--------<-------- TRANSMIT ON 440 BAND

13.1    ENABLE SPEAKER FULL-DUPLEX

        Enabling the speaker will cause feedback unless an external
        earphone or headset is used.

          1. Press and hold the FUNC key, then press the * key. The LCD
             should display FL. 

          2. Press and hold the FUNC key, then press the 5 key. The LCD
             should display Fd-on. Repeat this step until the field
             indicates Fd-on.

          3. Press and hold the FUNC key, then press the FL/PL key
             repeatedly until the FL and PL indicators are absent from the
             LCD display. 

13.2    DISABLE SPEAKER SEMI-DUPLEX

        Perform the following steps:

          1. Press and hold the FUNC key, then press the * key. The LCD
             should display FL. 

          2. Press and hold the FUNC key, then press the 5 key. The LCD
             should display Fd-oF. Repeat this step until the field
             indicates Fd-oF. 

          3. Press and hold the FUNC key, then press the FL/PL key
             repeatedly until the FL and PL indicators are absent from the
             LCD display.

14      AIRCRAFT RECEIVE MODIFICATION

        The radio will have to be opened and modified to receive aircraft
        and some frequencies in the 800 and 900Mhz region. This procedure
        isn't difficult if you take your time. If you are unsure of your
        ability to open and/or perform this mod, please find someone with
        this know how!
                               *** NOTE ***

          Don't even think of performing this modification unless you
          have the right tools and temperament. 

          1. Turn the radio off and remove the battery pack.

          2. CAREFULLY remove the 4 phillips screws on the bottom of the
             radio. These screws represent each corner of the               
             bottom of the radio. 

                                Front of Radio
                      +---------------------------------+
                      |  * <- Remove these screws -> *  |
                      |                                 |
                      |  * <- Remove these screws -> *  |
                      +---------------------------------+

                          BOTTOM VIEW OF RADIO SHOWN

          3. You are about to remove the battery connector plate. There are
             wires connected to this plate. When moving the plate out of
             the way, don't pull further then you have to in order to see
             into the bottom of the radio. Locate a BRIGHT RED LOOPED WIRE.
             Remove or cut (tape exposed ends) this jumper. That's all
             there is folks!

                              *** WARNING ***

             You should be extremely careful not to cut the wrong wire. You
             may cut the BRIGHT RED LOOPED WIRE. Don't cut the pink or
             orange wire by mistake.


          4. Take your time and reassemble the radio. Make sure that during
             reassembly that you:

             o  Don't forget to place long tension arm (part of the battery
                connector plate) into the battery lock clip located on the
                same side of the radio as the PTT switch.

             REMEMBER, be patient and take your time. Never force anything
             together! It came apart easily, it should go back together
             that way. 

          5. Reset the radio (Section 9.3) and enjoy a hot aircraft
             receiver. You will be able to enter a frequency range from
             108-173.995MHz. The receiver will actually begin to receive
             around 110 MHz.  Another way to gain access into the airband
             is, press the "FUNC" button while pressing the "VHF" key. 

                                  Page 50

                           *** MULTI BAND RECEIVE ***

          After you modified your DJ-580 for Airband, you also enable
          coverage for some frequencies in the 800 and 900Mhz region. To
          receive coverage in this area, you can enter the frequency
          directly from the keypad or press the "FUNC" button while
          pressing the "UHF" key. The STEP key in regions will only allow
          increments of 10, 12.5, 20 and 25KHz.

                               *** NOTE ***
 
          If you see a second decimal point blink in the frequency
          displayed, this means that the PLL circuitry isn't locked.
          Example:  108.0.0
                         ^____ This decimal point will blink.
