enough position to carry tl1cm through. So it" as'' ith these tdeas in mind that I took office and \\aS determined. with of course the appro\ at of the majority of the Headquarters Committee. to implement them. Ten items were placed before the Council at our first meeting. I am pleased that tl1ese ideas ha,·c come to fruit ion and members \\ill hopefully sec the fruits of our effo11s in the coming year. REUT!ONS My first objective was to con sol idatc our relations '' ith sister organisations and settle an~ outstanding dues which may exist. Contact was made with lA R U. RSG B. A R R L. DA RC. SARL. JAR Land our locallicenci ng authority, PTC. Many replies \\ere received offering encouragement and support. It \\as b~ sheer chance that shortly after the last AGM, we had a visit from several senior members of DARC \\ho were entertained at Z2l HJ · s QTH. (Guenther). Discussions were held with oncofthc managers ofDARC who ensured us oflheir support in the form of 2 and 80 metre radio kits. Additionally, \\e have been offered radio related books at reduced price by the SARL. Our membership dues for IAR U. "hich had been outstanding for some time. were also settled with no bureaucratic problems. At the IARU Region I conference in Bclgiwn in September 1993. Zimbabwe was represented for the first time. albeit by proxy held by the SARL. STARS (PADC) For some years now, Council had been approached by PADC (Promotion of Amateur Radio in Dereloping Countries), now called STARS (Support for The Amateur Radio Societies). This organisation is an arm of the lARU with South Africa as the Regional Co-Ordmator. Their aim is to assist societies in dereloping Amateur Radio by providing equipment eto where required. Unfortunately. contact was not followed through and no further contact was pursued. However in our programme of consolidation of relations. STARS was foremost and the acceptance of their principles by Council has led to another successful propagation of an tdca. More on this later. MJ.MBER~'H!P AND Sl/BS'CR.IPT!ONS On going through our membership. I was conccmed at the number of members who \\Cre in arrears" ith their subscriptions. I felt that it was unfair on members who regularly settle their dues to carry those \\ho do not. With this in mind, I set about chasing those in arrears and threatening suspension of membership facilities for those who did not settle.

Immediately after taking office. an informal meeting \\liS held \\ith the licencmg authority. The atmosphere was extremely positive and it was agreed that we \\Ould work together to modernise and upgrade llie Amateur Service regulations as well as de-regulating someofthe procedures. To this end. a regulations sub-conunittee was fonned to handle this task. prior to presenting the proposals to the PTC Chaim1an Des. Z2 1 GH. and his committee have made considerable progress and it is hoped to finalise this during the current year JA!U. DONATION Some years ago. an otTer was made to ZARS by JARL ofh\ O HF transceivers. The otTer was made through the offices of the Ministry of Information. Therefore. any communications to JARL could only be done through the Ministry. Unfortw1atcly. due to bureaucracy and red tape. plus changes in Council conunittce at the time. all correspondence " cnt awry and the matter fell into oblivion. It has always been m~ intention not to let this otTer go astray and to this, correspondence was revh ed. and contact was again made" ith the JARL through the Minist ry We still await further news. QSL BUREAU The bureau operations are now solely controlled by Maarten. Z2 1GY, thereby taking the load off the

Secretary. Moll:-. Dramatic increases in postage charges will mean restricting clearance of cards to parcels weighing at least 250 grams to take advantage of the minimum rate. JNTRUnER WATCH George. Z24JS/Z21 JW has as usual been kept very busy in this arca. lntroders continue to plague our bands \\ith little assistance forthcoming from International authorities to removing them. George has regularly sent in intruder reports to the JARU Monitoring service and has earned the Society a good name in this regard. BHACONS Zimbabwe no\\ has a beacon operating on the 6 metre band operating from the QTH of Mal. Z23JO in

Centenary, and the Matabclcland beacon,Z21ANB continues to operate well. Thanks go to all those in\'olved in maintaining these important areas.

For example, with mode A operation all you need is a restricted/R license toopcratelhe 2meteruplink even though thedo,m-link is in the fulllicenseportionof the I 0 meter band. You are not transmitting in a portion of the band your license docs not pcm1it. Again, the best place to start is mode A on RS-1 0.

You will find that a 2 meter all-mode radio is more expensive than the FM only variety. but the extra im·cst· mentis worth it if you plan to be acti,·e on satellites.

Once you are operational on these satellites you will find that thC\· casilv CO\ er most parts of Conttnental Africa. the Indian ckean Islands. and the Southern European countries. From , ·our Meiliesburg location, the kind of contacts you wit( be able to make depends on the pass of the satellite. For example if RS-1 0 passes directly o\·cr Harare the eastern part of Africa "ill be covered as well. A pass that moves across the central part of Africa will letvoumakecontacts as far as Namibia(V51 )onthc\\cst co~st. There is a group of Amateurs m Cape T 0\m. South Africa. who are consistently on RS-1 0/11 looking for contacts to the North. On most passes ~ ou \\ill be able to contact them For someone with no satellite experience. the best" a~· to get started is to begin tracking some of tJ1e satellites and listening to the down-linJ... This " ill gi' e you a chance to get your feet wet without adding additional hard,,are. Once you can hear the satellites. your interest ' ' ill gro'' and you will begin planning for your first 2-\\ ay satellite QSO.

who wait. and it is a pleasure to report that DOVE­OSCAR-17 is uttering its first words! Congratu· lations to Jim White. WDOE. and the other space­craft controllers for their fine effort in bringing this injured satellite back to life. UNAMSAT-1 NEWS The launch campaign for the UNA MSAT-1 MicroSat is currently undema~ \\ith launch set for 15th June. but there is a possibility that it might be delayed about one week. . The laWJch will be on a refurbished Soviet SS-1 K ICBM designed to cam· satellites. The final Keplcrian elements of the intended orbit are not knO\m. but the kno,,n parameters arc as follows: Orbital inclination = 73 degrees: Altitude = 730 KM: Orbital Eccentricity = 0.00000000 UNAMSAT· I·s pnmary mission is to act as me­teorsounder. When UNAMSAT-1 is not mvolved in meteor research. it can be turned into a standard PACSA T messagestore-and-fom ardsatellitc and data will be sent using standard amateur AX.25 packet but the actual frequencies ha,·en ·t been determined yet.

The IARU Administrati\e Cow1cil determined the the IARU mem­ber that had represented the SO\ iet Union. the Radio Sport Federallon of the USSR. no longer existed b~ ' irtue of the fact that the country it had represented no longer existed. Therefore. at the present time, there is no member society representing Russia ..
