Peter showed a neat idea for testing toroid cores without needing a non-50 ohm dummy load, he made a step down and step up pair:

Graham, VK2GRA, showed his excellent work with a 9m squid pole used as an HF vertical with tape measures as non-resonant counterpoises:

But the star of the day was Bob Mutton VK2ZRM showed his fantastic work on a high power solid state linear amplifier:

One of the many interesting things is the ARF463 A and B which are a matched pair but with different pin outs designed for push pull operation while earthing the source on each.

I had to rush off to a family function but happily the dog hadn't got the apple pie by the time I arrived.

Myles VK6ZRY I recognise the 50 Watt dummy load, I have quite a few ex Mobile racks (GSM).
AMAZING !!!
