Subject: DJ-580 Operating Manual

                            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
                  offset will be displayed on the LCD display.

               3. Rotate the Main Tuning dial or press either arrow key to
                  select the desired offset. For larger incremental frequency
                  changes, press the FUNC key then rotate the Main Tuning
                  dial.

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

            3. Select the Active Band by pressing the VHF or UHF key to set
               channel step and return to operating frequency.

               After channel step is set, the receive/transmit frequency will
               increase or decrease by the value selected when you turn the
               Main Tuning dial.

               When the transmit frequency extends beyond permissible limits,
               Off will be displayed on the LCD display. The transmitter will
               not transmit when Off is displayed. Refer to the following
               OFFSET frequency chart (TABLE 1) before you actually transmit.

                                    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.

           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.

   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.

   8.4.1  DUAL BAND SCAN

          You may want to scan both bands at the same time. You can perform
          that function by following this example.

                                    Page 33

            9. Press the SCN key for approx. 1 second.

           10. Press the PRI key.

   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.

               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.

               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.

               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

  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

  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.

  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.
