NOVEMBER EDITORIAL

Welcome once again to another cluUsnewsletter but unfortunately as I was justsitting down to write t}is I receive.d anressage from Margaret GM0ALXcancelling the Quiz Night that was due totake place on the 23rd October. There:$on for this cancellation was the newsthat Margaret's mother had suddenlypassed away on Monday 16th October. Itherefore would on behalf of the club liketo wish Margaret and all her family ourdeepest sympathies on this suddenbereavement.Moving on to events that have andhaven'ttakenplace. First of all itwasnice to see that many turned up early lastmonth to see the presentation of ourdonation to the British HeartFoundation. Photographs were taken bythe East Lothian News and East LothianCourier and have since appeared in therespective papers-By the time that this newsletter is beingread we will have taken part in JOTA atGullane so again it is great to get an

oportunity to Demonstrate what ourhdoby is all about. A fuller report willappear in next months newsletter.See also in this nervsletter a fuller reporton how all the other stations fared duringthe Northern Lighthouse Weekend as s€ntto me by Mike GM4SUC of the A1t RadioClub.Looking to the future I hope many ofyouwill make the effort to come and seeand listen to Ron Livesey on the Aurora

NEWSLETTER

Talk, believe you me you will not bedisappointed.For those who have committed themselvesto the "Chinese Banquet" night then Ihave now made the booking and paid thedeposit. We are going to Karen'sCantonese Restaurant in Dalziel Place,Edinburgh (ust past MeadowbankStadium)andthe meal is atZA3O. Ipropose that we all meet in the LoungeBar of the Hop,Step and Jump inMarionville Road (about 20 yards to therear of the restaurant) at 20:00 beforegoing for our meal. The meal itself willbe f,15 per head (already agreed) pluswhat we spend on any drink. There we gothen lets enjoy ourselves.l,ooking further to the future ie 1996 I amlooking for ideas for talks, visits,etc socan I please have them so I can gpt downto some organising. For information Ihave the following items in the pipline-- Radio Night, February: Talk onBritish Heart Foundation, Date to bearranged: DF Night, Date to be arranged:PW Contest, June: RSGB VHFFieldDa5 July: Junk Night, l6th August:Historic Scotland Special Event Station,24l25th August.Could I please ask can you let me knoweither via packet or in writing as too behonest "Friday Nights" are sometimes nota good time to tell me !!!! Thanks inadvance.From the last paragraph you will see thatI have now booked the CommunityCentre for our 3rd Annual Junk Night sohopefrrlly that again will be a roaringsuccess. As well we have been asked againby the Ayr ARC to put on a Special EventStation with th€ theme this time beingHistoric Scotland with an emphasis onCastles and I am sure we can find one inEast Lothian.I think that's about it but nodoubt I will have missed something so allthat's left to say is once again enjoy theNewsletter.

EVENTS FOR NEXT YEARNext month sees the end of what I think

can be classed as a very good one for ourclub. We have hadvery many successfirllwents and the club itself is becomingmore widely known as a result of thesevarious activities.In the main this has been due to hard workand enthusiasm but it is seen that a lotmore input is required from members ifthis success has to be continued.OK its great that we can all get together inthe Thorntree once a month and talk aboutour hoHry in general but a lot of workgoes on behind the scenes between clubdates as well.What we need is more participation frommembers on what the club could do inrespect of projects, outings, newslettermntent , contests etc.I do keep asking for members input butthis is sadly lacking especially with regardto the newsletter.ANYWAY the main reason for thiscolumn is to once again ask members totry and come up with reasonablesuggestions on activities they would like tosee the club doing next year. We havealready some firm dates for 1996 whichwill be published in the near future butneed help to fill the calendar.

Now the right way to tune it up (as $e do it) is to use atestbox,sig gen etc.I didn't have any ofthese things and assurne you dont either butcan still be tunedupok.Receiver alignmentSet up your 9.6v supply connect up to transceiver.Now to get thecrystal on the right frequency they use a test point and tune forly +- 0.2v but you need to apply the exact frequency from asignal generator.Not easy if you don't have one.All I can suggesthere is tune the off-air received signal for minimum distortionwith the relative crystal trimmeras marked on the metal shieldwhich covers the crystals area.

narrow switching bandwidth. For the rf alignment I used arealistic handheld scanner to give a signal at the requiredfrequency .The i.f. of this receiver is i0.E5Mhz so to get asignal on e.g. 433.000Mh2 then I would tune the receiver I443.850Mh2.I could also listen to the local oscillator on the p5012 usingthe scanner for tuning. A 70cm rig would also give you asignal source ifyou can borrow one.Basically now tune for minimum noise from loudspeakerand once you get the set a bit more sensitive you will have 1reduce the signal from the scimner etc just by moving itfurther away!!!!Adjusiboard 2 pornts I then 2 andthen board I points6,7,I,3,+ in that order for maximum quieting of signal .I didn't do anything else to the receiver it seemed ok at thatThere is an adj*stment to board 1 point 5 for min distortiorbut I just left this alone .I've had two or three qso's with the

Heie for indicadbn of \gw it was tuning up I used ar::!

swT/power meter.'ttriSbfficiat way of seffing up tx is to initially key the ptt anset/{fitjust board 7 point 1 for 2 +-0,2lr at p-a.You also neeca scope so Ijust adjusted this to make sure the tx stayed onok ! ! !You should be ok as the Lr freqs are not far apart but toreally set up the tx if they were you would need a scope.Now I used the power meter as follows:Plug in an whip aerial or similiar to transceiver socket onmeter.Put a dummy load an aerial socket of meter.Place p5012'saerial near to whip aerial of meter.Key the pft should seesome indication on meter adjust calibrate knob onmeter fora higher reading ifrequired.With a l.5w pa tune board 8 points 2 and3 alternatively formax power and then tune board I poittt for I.6w out 0couldnt do this accurately so set up as above and set boardI point I for max power out and then turned power down abit .Repeat tuning board 8 points 2 and 3 until interactionceases between adjustments.Then I just set up appropriate freq with a freq counter!!There are other things to be done e.g. checking currentdrawn on tx should be less than 750ma and deviation settinbut I just left alone since the set had just come out of servicrIf you have a 4w pa I can give you details on tuning it .l.5wpa l^T28504|4W PA AT28503t-The manual will give you extra details but I managed to getthe set down from 460lvfrrz using above tips ok.As I say ifnot sure about arything above get back in touchor check the manual.Cheers for now.....
