Have You Heard About World Wide Flora and Fauna in Amateur Radio?
Adam, VK2YK, went on an expedition to an island by kayak. Then, out of a small bag of tricks, he pulled out the components of a radio system and began to make contact as part of the World Wide Flora & Fauna (WWFF) contest. You can see Adam in action in the short YouTube video made by VK2MRX. Click on the Play arrow in the graphic below.
