    This is an upcoming one off chance to try a ham radio transceiver on the antennas at Radio Australia, Shepparton, before it is completely demolished.
    Have you ever wondered how a 20db HF curtain array would work?

    Watch http://www.sadarc.org/index.php/radio-australia-special-event/ for updates. Registrations for a space will open soon.

    I grew up listening to RA in the wee hours on 31m. It’s so sad that they were shut down. It feels like part of my childhood has been erased. :(

    Yes, I feel it is a stupid decision. And the equipment is being scrapped so it cannot be started up again. Very sad indeed.
    I am a bit biased as it was my work place for almost 20 years. But I have not talked with anyone who thinks it is a good decision.

    The crew-members that eventually will man the station are in for an experience.

    Some 10 years ago, a group of radio amateurs managed to "borrow" the Hörby transmitting site for Radio Sweden International shortly before the transmitting equipment was sold as spare parts and the antennas were demolished.

    There were a total of 5 curtain and log-periodic antennas available with gain figures in the 14 to 23 dBi ranges.

    As the site had belonged to my previous employer, I was invited to the event.

    For a week-end, multi-operator multi-transmitter operations on the 7,14,18 and 21 MHz band, using 1 kW transmitters were made with very good results.

    Some pictures:

    Glad to be part of a special event and I am bringing my MORSE Key for 40m USA, I watched the ABC wrap up of RA and could see there will be no coming back, 400 houses will fit in that block worth billion$, sadly.

    That would be fun to work with my European Distributed Fed Curtain which also has about 18 to 20 DB

    KOU Rhombic Antenna Farm is located at the Kansas QTH with over Two miles of Wire in the Air & On the Air, “The RF Gotta-Go-Somewhere"!
