ARLA/CLUSTER: Airspy HF+ pretende ser o novo paradigma dos receptores SDR`s em HF e VHF

[Rui Oliveira [CR7ALW]]

Já há alguns servidores de sdr online que usam o equipamento:
https://airspy.com/spy-servers/

Vejam pelos próprios olhos. Isto é uma performance de HF totalmente 
"flagship" (ou melhor) e não vai custar o preço de um flagship 
(150-200€, algures por aí). Aliás, este dispositivo tem causado imenso 
desconforto juntos dos developers e fãs do Perseus e coisas do género.
