Colega João ai está o problema .<br>Por haver muita riqueza e por sua vez muita ganancia da parte de alguns é que esses países estão como estão.<br>Esperemos que as coisas melhorem em termos radioamadoristicos por aqueles lados.<br>

Boa Tarde Pedro Almeida,<br>
<br>
A África do Sul como muitos países de África não são propriamente "países pobres", antes e como em Portugal, a riqueza está é mal distribuída ou para ser politicamente correcto; existem profundas assimetrias socioeconómicas.<br>

<br>
<br>
E pronto o continente Africano já tem D-STAR.<br>
Para quem defendia que o D-STAR era dos Países "ricos" enganou-se.<br>

The first digital repeater in Johannesburg is active on the air.<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
To operate the D-Star repeater switch any D-Star enabled digital radio to DV mode. Tune to 145.6875 MHz with the usual -600kHz 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.<br>
<br>
The SARL is looking for coverage, signal reports and comments.<br>
