RE: ARLA/CLUSTER: 1º Repetidor D-Star em Joanesburgo, África do Sul,

[Eduardo Arraia]

Boa tarde,

Concordo e gostei do politicamente correcto "existem profundas assimetrias
socioeconómicas"

Esta história de pais de 3º mundo é coisa de ocidentais e companhia
limitada...

Do 3º mundo seremos nós... basta eles fecharem a torneira... é que nós nem
torneira temos para fechar...

Boa Tarde Pedro Almeida,
 
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.

João Costa, CT1FBF

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

	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 -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.
	
	The SARL is looking for coverage, signal reports and comments.
	
	Send your comments to armi  sarl.org.za.
