Hey hams. I've been thinking about getting a ham license, more specifically the german class A which would be CEPT or our equivalent to the american amateur extra license.
I know everyone is different but how long do you think studying for it would take?
I only have very basic knowledge when it comes to electrical engineering stuff but I do come from a math background.

My main interest/motivation is SDR stuff which I want to get into so studying for a license seems like a good way to gather some verifiable basic knowledge and get something out of it along the way.

Also: If I am licensed, can I get something like a Quansheng UV-5 to give to my wife (or any unlicensed person) and operate/set it up in such a way that I can communicate with her within legal boundaries?
Can something like a (more expensive) ham hand radio communicate with one those simple hand radios anyone can buy/use?
