Hi I am organising with our local amatuer radio people to have World Thinking Day On Air; they are going to bring their equipment to our hall etc., and all is okay for that. However, I am a bit confused; has anyone ever done this before and what is the procedure, because I think I am not 'getting' something with it. Basically, I understand that 1. I invite members to attend event etc. 2. Radio people turn up as arranged with equipment. 3. Members chat on air with other Units. My questions I suppose are:- 1. How do I know which other units are taking part and when they will be on air so we can chat? 2. Is it an appointment sort of chat or do you just tune your radio and hope to get another guiding unit rather than Bill down the road? I just don't get it - any help in plain simple language would be helpful. Thanks.
