(Araucaria) [vhf-dx] Noticia triste OSCAR 52 SK

[Paulo PV8DX]

Oi Peter

Quem anda nas QRGs dos SATs tem tido um profundo pesar. Desde do dia 11 
que os
mais experientes tentavam  buscar uma explicação para o QRT do HAMSAT.
Sem dúvida um dos melhores.
O AO7, que está capengando, mas ainda em atividade.....Aliás, são 40 
anos de TX.... (O transmissor é alemão....tá explicado....hihihi)
Hoje, estamos a presenciar os CUBEs a proliferar o espaço com alguns 
destinado ao radioamadorismo.
Embora com vida reduzida tem ao menos movimentado as QRGs.
