The South African Radio Development Trust invites nominations for the 2008 radio amateur awards sponsored by Nokia-Siemens Networks. The technical award introduced last year has been renamed the Garth Milne Technology Award in recognition of the contributions the late Garth Milne made to the development of amateur radio satellites in South Africa. He was responsible for having amateur radio included in SUNSAT and facilitated the amateur payload on the soon to be launched SumbandilaSat. The Garth Milne Award recognises technical innovation in Amateur Radio.

The Nokia Siemens Networks Radio Amateur of the Year Award recognises a person for his or her contribution to the development of Amateur Radio and the Amateur Radio Community Service Award recognises a person or a group of persons who have rendered service to the community.

Full details and nomination forms are available on or by requesting the documents by sending an email to

The closing date for nominations is 21 April 2008.

The objective of the SARL Radio Technology symposium is to expose radio amateurs and electronic hobbyists to new technologies and developments in amateur radio and communication, which the programme achieves with a high standard of presentations on many subjects, that are cutting edge.

With so little general exposure to new technologies, one would have expected larger attendances. If you did not attend, drop us a line and tell us why so that we can address any concerns you may have for future RTA’s. Send an e-mail to Feedback from most of the 40 delegates who attended was good.

The next two RTA’s are in Durban on 14 May and Port Elizabeth on 31 May. Watch the web for details.

The two metre beacon project initiated by John Sygo, ZS6JON, now has four beacons on the air, with a number to go live very soon. The output of the beacons varies between 10 and 20 W. The keyers that have been donated by John, ZS6EF, work in two modes. Once the beacon has started up it keys the rig in FM and sends out the station’s call sign in CW followed by the grid locator. Then comes the same message in a keying FM format that enables operators with CW/SSB capabilities to receive the beacon. The message is then repeated continuously. The beacons you can listen out for are:

ZS6SRL, NARC on 144,405 MHz; ZS4AFV, Bloemfontein on 144,415 MHz; ZS5LEE, Durban on 144,420 MHz, and ZS1NAZ, Cape Town on 144,435 MHz. Reception reports can be posted to the ZSVHF mailing list and sent to the beacon custodians.


The organising committee would like to notify members that the closing date of 6 April for booking has to do with attendance figures for the catering at the various functions and has nothing to do with accommodation. Members must arrange their own accommodation. The function booking form and a list of accommodation is available on or may be requested from


A group of radio amateurs has established the Tshwane Amateur Radio Construction Group. The aim of this group is to assist all amateurs in constructing their own needs in the communications environment and any amateur may join. The only financial implication applicable will be for construction material, which will be utilised if not sponsored by the members. The next planned construction day will be on Saturday 22 March 2008 at 13:00 at the home of Len, ZS6LEN.

If you are interested in finding out about the construction of an 80 m antenna using 2 metre PVC pipe, some of the wife's aluminium foil and a few turns of coated copper wire, you can contact Len, ZS6LEN, at 012 345 4447 / 082 416 2598 or Whitey, ZS6JJJ, at 012 993 1167 / 082 416 7250.

The Kempton Park Amateur Radio Technical Society (KARTS) held its AGM on Saturday 8 March 2008. The following committee was elected:

Chairman - Clive Reeks, ZS6BT; Vice Chairman - Viv Dold, ZS6VD; Secretary - Theo Barkhuizen, ZS6KI and Finance - Paul Cornelius, ZS6PJC.

The Society also bid farewell to Hannes, ZS6LW, who will shortly be moving to New Zealand.


Hannes Coetzee, ZS6BZP, reports that the expected solar activity will be very low. The geomagnetic field is expected to be mostly quiet. The expected Effective Sun Spot number for the coming week will be less than 5. DX conditions will generally be good on the Northeast and poor in the general Northerly directions.

15 m and 20 m will provide best opportunities for DX. There is a possibility of 15 and 20 m openings towards India from about 14:00 CAT. There may be short, weak 20 m openings to Australia from 08:00. From 15:00, there may be short 15 and 20 m openings towards Europe. Contacts with the USA are going to be very challenging. 10 MHz is looking promising after dark for the CW and digital enthusiasts.

Local conditions are going to be good on 40 m during the daytime. 30 m may perform well during the middle of the day over the longer distances. 80 m is the frequency of choice in the evenings, thunderstorms and static permitting! Remember that this is only a prediction and that HF always has the capability to surprise you, but you will never know unless you switch your rig on, listen and also call CQ.
