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) website (click here). There are organisations like this in every country so in the UK look up the RSGB and in the US you’ll find the 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.
