Today was a meeting of the Amateur Radio NSW Home Brew and Experimenter's group at Dural. The topic was duplexers, diplexers and filters. I shot some video which begins with some footage of the VK2WI broadcast.
Thanks to everyone who presented. Sorry about the hand-held video but this time I'm using a wireless mic for the first time so audio is much more intelligible.
The video has been tweaked and updated but it's the same as before.
