1. Might be able to use the FCC DB to look it up.

2. Hobby and EmCom. When I lived in Texas most of the clubs were HF contest based. Now I’m in the PNW and lots of the clubs are EmCom based which is interesting. Lots of neat operating modes just in Tech class. APRS, Satellite, Ham mesh networking.

3. Yes. If you want DX CW is a great way to do it.

I think radio is a great hobby. Bit expensive but still very relevant. I’ve learned a ton by practical application.
