     Reflecticns on GRM

                 Qi has been produced on a regular basis for the past seven years - a
     very splendid effort!  Most of the thanks can go to John VK7JV without whose
     efforts it might have fallen by the wayside.     It was felt however, that the effort
     required to produce this magazine should be shared by more than one person = to
     this end a production committee has been formed. John, on behalf of all the
     members of the North and Northwest branches may we thank you for your hard work
     over the years.

                 The objectives of QRM are again worth looking at. These are to foster
     Amateur Radio by keeping Amateurs in the North in touch with one another - and to
     provide a medium for discussing technical and administrative matters,

                 From time to time complaints are heard (grapevine style) about some
     aspects of QBM.   e.g.    ™de don't need QRM because we know everything that goes on"
     or "Not enough technical articles" - either that or'its too technical". Unless
     constructive feedback is received its difficult to know what members really want.
     If articles are received from the same members all the time the field of interest
     must be limited.

                 We want this magazine to be interesting and informative - to achieve
     this we need your articles. At our end we can introduce items on different facets
     of amateur radio = as we have in this issue, but mainly we need your assistance.
     QRM can only be as interesting as the members will allow it to be,

                        It was agreed by members at the last meeting that the sum of #50.00
            be donated from branch funds to the Glenara Boys Home. The money is needed to
            assist in rebuilding part of the home which was destroyed as a result of a
            disastrous fire in March,

                        The Minihamfest was held on the 12th March at Launceston Airport.
            Once again the Northwest branch won the cricket match - but only by a slim
            margin! In between the various segments of the Air Pageant which was watched
            "free of charge" everyone ate and drank their fill. Linsey VK7ZID and family
            won the DF Hunt.

      THE TELEVISION SYSTEM ~ PART 1 - MALCOLM VK7ZMM

               To understand how a television system works it is necessary to understand a
      little about the workings.

               The system used in this country consists of 625 lines of information which
      forms on frame or single picture as in a movie film, One frame is transmitted every
      40 milliseconds and corresponds to a frequency of 25 Hertze Now if only one scan
      from top to bottom of the picture were transmitted in this time flicker would occur
      whilst viewing the picture. To get around this problem without increasing the rate
      at which information is transmitted i.e. the number of fields per second, the
      picture or frame is divided into two parts. The first consists of all the odd
      numbered lines in the frame, the second part all the even numbered lines. These
      two parts of a frame are called FIELDS and are transmitted one after the other.
      By using this method the rate at which the picture or the phosphorons of the
      receiver is updated is doubled without increasing the rate at which the information
      is transmitted. This process is called INTERLACING. It is used in all current
      television systems., The advantages are a greater resolution without increasing the
      amount of spectrum used by the signal.

                DX NOTES      -      COL    VK71Z

                         Last November I advised 7JV that I would not be writing these notes in
                1978, John talked me into carrying on until the end of our financial year, now
                our worthy President has convinced me that I should keep up the good (?) work
                until a successor is found = Any offers? - Unfortunately I had not kept notes
                in the interim,

                           3.5 m/h     Andre (VK7AE) is still getting the odd dx station on SSB and
                has built his              score up to 22 countries on this band,

                           7 ?/hz      No reports have come to hand and I haven't done any listening
                here,            '
                         14 "    Still on gke "up and up". Reports of Eurcpeans coming through
                from 1600Z to 55002 have been received. Southern africans can appear around
                06002, sometimes short path and at other times over the long route so check both
                ways. West and north Africa has also been ¢SC'ed between 0700 and 0800Z long
                path whilst South America came through between 0700 and 10002 - The pick of the
                stations logged here were EAGET, ELIL, FB8XS Kerguelen Is., FB8YF, Antarctica,
                JW9UV, JY5HH, IX1LT, PY@FN Fernando de Noronha, TR8LE, VPS8PP, VP8PT, ZELUS,
                ZS2NF/S8, ZS5KI and 3V&BZ all on SSB.
                         21 m/£2 Central, South American and South africans have been logged
                between 03002    and 06002 and Europeans have been copied from 0730Z onwards
                but it doean't happen every day.

                           28 m/hz Other DXers tell me that there is some good DX appearing at
                times but T                cannot confirm.

                         The only DX pedition I*ve received news about is P29JS' visit to the
                Cocos Island (VK9) possibly from the 31st May for 14 days.

                  Plugs and jacks are used not only to connect various units of electronic equipmenttogether,
                 but also to perform a variety of switching oparations at the same time. To test your sbility to
                 analyze plug and jack connections, sharpen your pencil and try working the circuit problems
                 (1-8) shown below. Determine the total equwalent resistance between points A and B in each
                 circuit BEFORE and AFTER the plug is inserted in the jack. All of the resistors are 6-ohm units.

    THIS CIRCUIT 1S EASY TO ASSEMBLE AND ADJUST AND DOES A GOOD JOB,
     IT WiLL COPY BOTH wWIDE AND NARROwW SHIFT., THE CIRCUIT USES A 741
    AS A LIMITER, AN N565 PHASE LOCK LA0P IC, ANOTHER 741 AS VOLTAGE
    COMPARATOR OR ** SLICER’’ AND AN MJE340 KEYING TRANSISTOR,
         THE TERMINAL UNIT (TU) HAS NO FILTERS BECUASE IT WORKS ON THE
    FM PRINCIPAL, THE THEORY OF OPERATION OF THE PHASE LOCK LOOP wiLL
     BE EXPLAINED FULLY LATER, BUT A GENERAL UNDERSTANDING NOw WILL BE
     HELPFUL. SIMPLY STATED, THE INCOMING SIGNAL LOCKS ON A VOLTAGE
    CONTROLLED OSCILLATOR IN THE IC., THE FREQUENCY OF THE OSCILLATOR
     IS PLACED BETWEEN THE FREQUENCIES OF THE MARK/SPACE TONES. AS
    THESE TONES ALTERNATE THE OUTPUT OF THE PLL CAN BE MADE TO PRODUCE
     A PLUS AND MINUS VOLTAGE BY CONNECTING A VOLTAGE COMPARATOR TO IT,
    THIS PLUS AND MINUS VOLTAGE CORRESPONDS DIRECTLY TO THE MARK/SPACE
    TONES AND CAN BE USED TO KEY THE LOOPCIRCUIT OF THE TELETYPE
    MACHINE,
           THIS METHOD OF DEMODULATION HAS THE ADVANTAGE OF NO TUNED FILTEL
     AS STATED ABOVE AND wiLL TOLERATE CONSIDERABLE DRIFT AND COPY SHIFTS
    FROM 170 HZ TO 800 HZ. JUST BY PROPERLY TUNING IN THE SIGNAL,
    CONSTRUCTION REQUIRES NO PARTICULAR CARE AND A PERFORATED BOARD
    SERVES QUITE WELL. A REGULATED POWER SUPPLY OF 10-12 VDC, PLUS
    AND MINUS IS REQUIRED. SOCKETS SHOULD BE USED FOR THE ICS AND
    TRANSISTORS, THE PLL IC CAN BE MOUNTED IN A SOCKET OR MOLEX PINS
     (AVBL FROM THE CLUBROOMS),
           A TUNING METER |5 REQUIRED AND THE SIMPLEST (S A ZERO CENTRE
    MILLIAMETER WITH SUITABLE DROPPING RESISTOR, IT IS CONNECTED AS SHOwW!
     IN THE DIAGRAM, IT INDICATES A PLUS CURRENT ON MARK AND MUNUS ON
    SPACE, WHEN RECEIVING A PROPERLY TUNED FSK SIGNAL THE NEEDLE TENDS
    TO HOVER AROUND ZeRO CENTRE,     IF NO ZERO CENTRE METER IS AVAILABLE
v




    gSE A VTVM SET AT ABOUT 25 VDC AND ADVANCE THE NEEDLE TO CENTRE
      CALE,
             ADJUSTMENT IS EASYs AFTER CONNECTING THE LOOP VOLTAGE AND THE
    POWER SUPPLY FOR THE TU, CHECK THE PLUS AND MINUS VOLTAGES,
    THESE CAN BE 10-12 VOLTS BUT SHOULD BE THE SAME OR WITHIN .5 VOLTS
     INPUT CAN BE 500 OHMS OR EVEN THE SPEAKER OUTPUT OF THE RECEIVER
    WHICH WORKS QUITE wELL, NEXT, CLOSE SW1 , TUNE IN A GOOD STEADY
    NARROW SHIFT RTTY SIGNAL, PREFERABLY RUNNING A TAPE, THE RECEIVED
    TONES SHOULD BE IN THE VICINITY OFiMOO0 HZ, THIS CAN BE DONE BY
    EAR AND IS NOT CRITICAL, SET R1 AT THE END OF ROTATION WHICH IS
    MAX IMUM RESISTANCE, THE SERO CENTRez METER SHOULD READ APPROXIMATELY
    ZERO OR A LITTLE ON THE PLUS SIDE, NOW ADVANCE R1 . THE METER SHOULD
    MOVE MORE TO THE PLUS SIDE AND FLICKER BACK TOWARDS ZERO, IF IT DOES
    NOT, CHANGE SIDEBANDS IF YOU ARE RECEIVING IN THE SSB MODE, IF YOU
    ARE RECEIVING IN THE CwW MODE, MOVt THz BFO TO THE OTHER SIDE. OPEN
    SW1 AND TURN ON THE TELETYPE MACHINE, AS Ri IS FURTHER ADVANCED A
    POINT WILL BE REACHED WHERE THE MACHINE WILL BEGIN TO PRINT AND THE
    NEEDLE OF THE METER WILL STAY PRETTY NEAR ZERO DURING COPY AND
    MAX IMUM PLUS ON MARK/HOLD TONE, THIS IS THE SPOT WHERE R1 SHOULD BE
    SET. AS R1 IS ADVANCED WTILL MORE THE NEEDLE WILL GO BACK TOWARD
    THE MINUS SIDE AND EVENTUALLY THE MACHINE WILL RUN OPEN, WITH A
    LITTLE PRACTICE IN TUNING AND WATCHING THE METER A SIGNAL CAN BE
    TUNED IN WITH NO TROUBLE AT ALL, AFTER A WHILE YOU MAY WANT TO
    CHANGE R1, SLIGHTLY ONE WAY OR THE OTHER TO RECEIVE SIGNALS BETTER
    AT SOME SLIGHTLY DIFFERENT TONE. BUT ONE IT IS SET PROPERLY IT
    NEED NEVER BE CHANGED,

                              IT 1S POSSIBLE TO RECEIVE BOTH WIND AND NARROW SHIFT WITH ONE
                       SETTING OF R1 BUT IF IT 1S SET TO RECEIVE NARROW SHIFT, THe WIDE
                       SHIFT IS SOMETIMES HARD TO TUNE WITH THE SAME SETTING., HOWEVER,
                       SINCE NARROW SHIFT IS GERERALLY USED NOW , ONE SETTING FOR IT SHOULD
                       SUFFICE, IF YOU EXPECT TO RECEIVE BOTH SHIFTS REGULARLY IT WOULD
                       BE WELL TO INSTALL A SECOND POT WITH A SWITCH TO SELECT EITHER WiDE
                       OR NARROW SHIFT,
