> Algum dos Colegas tem escutado as frequências de "downlink" da ISS?

Para saber o "status" actual das actividades da ISS,
veja esta página: http://www.issfanclub.com/ no lado direito.

> órbitas muito favoráveis, não consigo obter nenhum sinal.

O problema não é seu, mas do rádio da ISS que está desconfigurado,
e ainda não foi possivel repor a configuração.
Para mais info, leia o report do Frank Baur.
