NEWSLETTER EVENTSCOLUMN

JUNE EDITORIAL Welcome once againto anothermonthly newsletterand as alwaysI hope that you will thoroughly enjoy its contents.Again as a reminderwe are alwayslooking for any input that you can give. My little causethis month is about carrying "items" on our cars after my "little run-in" with the law a few weeks ago when I was transporting a carpet home after buying it from a local store. It startedto make me think about when we go out portable, whether it be Contesting,SpecialEvent Stations,etc, etc, do we carry poles,etclegally on our ctrrs. Obviously, I am not 100% up on the legal side of things but it is worth a point to try and find out what \ryecan or cannot do. If you do know pleaselet us all know then we can be assuredthat we are then all law abiding citizens. Moving on, this last month for myself has quiet beenvery on the radio front from the shack point of view but I did thoroughly enjoy taking part, for a shod while, in the 43?t&tz Trophy Contest up at our usual MainslaughterLaw site along with Alex GM6VIU,Colin GM0CLN, Alan GMOUSI, Bill GMOICF, John GMTTKA and Cambell,it was a prty that conditionswere not great. Also our DF Hunt night againproved to be a real challengeand a good old laugh, its a pity that a few more don't take part, never mind. Well, this manth brings us to the PW Contest so why not come along and enjoy a bit of contesting and have a gocd laugh as well, who knows you may even catch the contestingbug. That's it then for anothermonth .. keep the Newsletter I npu t co m in g !!!!!!!l!!

DF HUNT NIGHT Friday 17th May, 18:30 duly arrived where those taking part in the DF Hunt Night met at the Pond Hall car park in eager anticipationof the first "Fox" signalat 19.00. Sadlyto say only three cars (teams)took part in the event but neverthe less we all really enjoyedthe evening.The teamsconsistedof Colin GMOCLN & Ron GMONTL, John GMTOLQ & Alec GM6VTU and Bill GMSZLI & myself. The Fox being Ron GM4IKU. The DF aerialsusedwere the Badger DF Kit (JohrlAlex and Bill llvlyself) and Colin a Homebrew HB9CV. 19:00arrived and we all departedlooking for that elusivesignal. Bill and myself decidedto just drive arounduntil we startedto hear the fox's signalfrom then on we startedDF'ing.

This took us up into the Athelstanefordare&where we endedup convincedthat Ron was hiding there,sadlythis proved not to be the caseafter going in and out all the nooks and cranniesthere EXCHANGE Exchangefor a printer suitablefor IBM PC I must admit we were getting somereal funny looks at times.. From this we startedgoing round in a circle to seeif we could SP/2 pin point the "fox" eventually I think more as a fluke than SINCLAIRQL anythingelsewe spottedRon very convenientlytucked away in a 2x 5l2kb computerkeyboardsc/w insider corner and YES BINGO we found him. Strangethough as at one time boardsfor 5.25 disk drive. we were no more than 100 yards from him yet the signallevel was lx Powerunit for above. very low this was due to a large mound of earth that was between lx FergussonMM02/1\4M0612" (v29) us, so it just showsyou that DF'ing is not an easyart. rnonochromemonitor c/w operating instructions. lx 5.25"Disk Drive lx Serial8056compactprinter. 2x Archive, Wordprocessor,Abacus & Eisel Programs.

Right you may ask about where were the others,to be honest it was a questionthat Bill and I had askedourselvesa few times during the event, we even thought that we had got it all wrong but it turns out that the otherswere samplingthe delights of and in and aroundHaddington,I am convincedthey went for an earlypint !!! Atty*ay at 20.45 Ron announcedhis "hidy hole" and everyone made for the Ship Inn in Port Seton for a DF Postmortem.The tales of woe, oh dear, where it all went wrong all cameout. The bottom line is, as said previous,that it is really a good bit of fun and believeyou me it is not as easyas you think to find that elusivesignal,so come on join in the next one and seewhat its all about.Till then....

provided As prornisediast monthhereis the detailsof the JVFAX & HAMCOMM INTERFACE as by StevieGMOWRY entries is Its a fairly easyprojectto get you onto Slow ScanTelevisionand Datacomms.lf there enough club (minimum4) it is propor"i that we hold a contestfor the bestbuilt unit to coincidewith one of our club! in the nights so come on g"i those solderingirons out and lets show that there are someconstructors

JVFAX & HAMCOMM INTERFACE The constructionof this circuit is quite simple.Thereare a few thingsto watch out for, makesurethe pieceof veroboardis larger than the layout drawing. Start by solderingthe resistorsfollowed by the diodes, your sockets' then the transistor7 potentiometer.Next the chip then the capacitors.last of all the wires for you use.Thereasonis Very importantl^ycheckyour manufacturersrecommendationsfor the tx of the radio ground' on the thatbsomeYaesuhandheldsyou must put in the 2.2 k resistorto stop the tx audio going to wire circuit diagramthere is a wire for the for the tx PTT. I did not use this on my version.I usedthe dotted this whichwhichgoesthrough aZ.Zkresistor via the link , then to the collectorofTRI 8C108. If you use Yaesu method you may not thin needthe wire connectedto pin 5 of the 5 pin DIN plug. (By the way I use a handheld) I hope you havefun building the circuit and if you needthe chip I havea couple available'also veroboard.If anyoneis interestedI could put a kit together. I have the softwareif anyoneneedthat too. great. This is a pioject really worth doing as the enjoymentobtainedfron receivinga picture over the air is ironsout............. so get thosesoldering I can ofFerhelp over the air or by packet radio.
