The first digital repeater in Johannesburg is active on the air. The repeater is on loan from Multisource for demonstration purposes and is offering amateurs an opportunity to experiment with D-Star. The system was installed and demonstrated during the SA-AMSAT event last Saturday at the NARC. Thanks to Ronald, ZS6RVC, Riaan, ZS4PR and Frik, ZS6FZ
D-STAR, the acronym for Digital Smart Technologies for Amateur Radio, is a digital voice and data protocol specification developed by the Japan Amateur Radio League. While there are other digital on-air technologies being used by amateurs, D-Star is one of the first on-air and packet-based standards.
D-STAR offer clearer signals and uses less bandwidth than its non-digital counterparts. As long as the signal strength is above a minimum threshold, and no multi-path is occurring, the quality of the data received is better than an analogue signal at the same strength.
D-Star compatible radios are available on VHF, UHF, and microwave amateur bands. In addition to the over-the-air protocol, D-Star also provides specifications for network connectivity, enabling D-Star radios to be connected to the Internet or other networks, with provisions for routing data streams of voice or packet data
To operate the D-Star repeater switch any D-Star enabled digital radio to DV mode. Tune to 145.6875 MHz with the usual -600 kHz offset to talk via the repeater.
In the radio menu ensure that R1 and/or R2 are set to ZS6TJ. The UR can be set to CQCQCQ, and MYCALL should be your own callsign.

The Sasolburg and Vaal Triangle Radio Clubs are hosting the 2011 SARL National Convention on 15 and 16 April. Enjoy the beauty of the Vaal, an evening cruise down Millionaires’ Bend and a fantastic dinner in the company of good radio friends until late Friday evening!
Saturday morning the SARL AGM at the Vaal University of Technology commences at 8 am with registration. The meeting starts at 9 am. In the afternoon a huge flea market will be held while a nature drive at Emerald Casino Resort will keep non-amateurs suitably entertained.
The Sasolburg and Vaal Triangle Radio Clubs expect this to be the biggest get-together of radio amateurs in years! The afternoon also offers a visit to the Bloemendal Shortwave wave radio broadcast station near Meyerton. Experience what a 50 kW RF transmitter is capable of doing, and see how the systems for such a shortwave broadcast station operate and service the world from South Africa.
The highlight of the convention takes place on Saturday evening at the Riviera Hotel. This year the SARL Gala evening will be a formal black tie affair, but suit and tie will also do! The guest speaker is Prof. Alwyn Louw from VUT. The well known band Broken Stream will supply the music while Gerald Klatzko, ZS6BTD, will be giving a riveting presentation on his experiences with MIR and the Space Station.. The annual prize giving will be hosted by Tjerk, ZS6P. Thereafter the dance music fires up and the party begins!
Registration for the Boat cruise and the Gala evening is essential as there are only limited seats available. Bookings should be made through the club secretary of ZS4SRK by visiting to complete the forms. There is also a link from

The Port Elizabeth ARS has released the results of the 2010 PEARS HF QSO Party held in early December. 10 unlimited and 1 restricted class log was received.
Unlimited class
1st Wes Wessels, ZS2A, 107 points
2nd Jacques Vermeulen, ZS1WC, 98 points
3rd Otto du Plessis, ZS2Q, 95 points

Piet Delport, ZR6BVS, 12 points

No logs were received in the Novice and DX classes. Well done to the winners.
Hannes Coetzee, ZS6BZP, reports that the solar activity is still at low levels. Sunspot 1147 persists in the northern hemisphere and a few tiny spots have formed just to the south of it. The effective sunspot number is expected to be less than 20 for the coming week.
15 m will provide the best opportunities for DX followed by 20 m. Conditions to India will be good from the afternoon till after sunset. During the afternoons conditions will be fair towards Europe on 15 m, later to be followed by fair 20 m openings. Early evening 15 m contacts with the USA are possible. Contacts with Australia are possible on 20 m at sunrise and during the afternoons. 15 and especially 20 m openings to Brazil and South America are possible during the afternoons. With the good 15 and 20 m openings 17 m will also be full of surprises.
For the CW and digital enthusiasts 30 m may be very rewarding with openings to many parts of the world.
Locally 40 m is the workhorse for contacts around the country with 20 and 30 m also being very useful for contacts over the longer distances. 80 m will be best during the early mornings and late afternoons as well as over the shorter distances.
80 m is the frequency of choice during the evenings.
Please visit for further information.
