  • AMR100

    A few weeks ago at the ARNSW Dural site I was talking with Mark Blackmore about the classic radios incorporated into the VK2WI broadcast building. He showed me some beautiful Collins receivers and some Racal sets. Also occupying a position on the equipment rack was a very shiny Kingsley AR7, the famously unauthorised copy of…

  • Australian Code Breakers

I remember being astounded to hear intercepted military signals from the early hours of the Falklands War being broadcast on the program. Long before…
