What is Amateur Radio ? That is a very good question !!!
If you’re not familiar with Amateur Radio also known as Ham Radio I’d suggest starting your journey at the Wireless Institute of Australia (WIA). There are organisations like this in every country so in the UK look up the Radio Society of Great Brittan (RSGB) and in the US you’ll find the Amateur Radio Relay League (ARRL).
However be warned that Amateur Radio is not a hobby it’s a life style choice (*grin*)…. I’ve been an Amateur Radio operator since 1995 and I have not grown bored or explored everything that Amateur Radio has to offer.
I’m also a founding member of the Amateur Radio Experimenters Group (AREG) here in Adelaide. You should definitely find out what my friends and myself get up to on weekends #wedocoolstuff
