You don't need a licence to listen to ham radio - you don't need a licence to listen on a transceiver - so if you really want to become a ham operator, then buy a transceiver and listen all you can then apply for your licence. Unfortunately the basic technician grade doesn't allow you to transmit on the HF bands - or does it in the USofA?
Tech grade allows CW in allotted portions of the 80, 40, 15, and 10 meter bands, and SSB in a small portion of the 10 meter band in the USA.
But your greater point is very true -- no license is needed to enjoy ham radio. I've been monitoring it for years. Sometimes it's fun, other times not so much. Even CW can be interesting if DX is in.
