Military medals including the Victoria Cross

At today's meeting, Graeme VK3CDO, gave a fascinating talk about military medals and ribbons.

When he did his NCOs course he had to do organisations, administrations, drill and many other subjects. Part of this was about rank and the badges that go with it. Also medals were covered.

Moorabbin Hamfest a great show

A few club members made the trip to the Moorabbin Hamfest which was a terrific show this year. Loads of interesting radios, test equipment, connectors and books were on sale. As well as beautifully restored older gear there was a display of modern Yaesu equipment. Towards the end of the morning's show prices started to come down and some tables were giving away what was left. It's worth staying to the end. Thanks to the organisers for a well run Hamfest, we look forward to next yea...
