    Eu tenho um dongle RTL-SDR que descodifica D-Star muito bem.
    Simplesmente hoje tenho muito ruído. Nem APRS consigo descodificar
    em condições hoje. <br>
    Um dia tenho de fazer uma apresentação sobre as maravilhas de ter um
    dongle destes. Quando tiver o dongle qeu faz HF eu penso nisso. CW,
    RTTY, J65, D-Star, APRS, etc etc etc. Desde que alguém faça um
    programa que descodifique, dá para descodificar.<br>
    As versões baratas disto (que é o que eu tenho) custam menos de 10€.
    Foi um hacker de hardware que descobriu que "pens" de ver tv no pc
    podem ser usadas como SDR's de recepção. O que já fiz com isto é
    extraordinário.<br>

                                          espalhados pelo território

                                          Lendo na diagonal os dados do

                                          vantagens deste sobre o
                                          D-Star, apenas que são
                                          provenientes de empresas

                                          A questão é, hoje em dia vale
                                          a pena investir num, no outro
                                          ou em nenhum? É que mesmo com

                                          Qual foi a razão principal das
                                          três associações investirem no
                                          Fusion e não no D-Star? Preço
                                          dos equipamentos? Inovação?
                                          Provavelmente, há semelhança
                                          do que ocorre nos portáteis, o
                                          preço andará ela por ela e
                                          fugir de um sistema que até

                                          "provado" em terras lusitanas
                                          parece-me no mínimo arriscado.
                                          Não estou a reclamar, estou
                                          apenas a tentar compreender o
                                          porquê. Bem sei que os que
