Frijid:
Since you posted that you enjoy radio, and evidently have explored a bit, I and any hams on CPF strongly encourage you to obtain a ham license to expand your enjoyment of a fun hobby.
If you want to work in radio/TV, then the rules change a bit. Then you will need a General RadioTelephone Operators' License, or GROL. Notably if an "L" is added at the end, that abbreviation has an unfortunate meaning in German.
Nonetheless, a ham license for the progressive classes and corresponding privileges, authorizes the holder to function in the amateur frequency bands, but does not provide the authorization to work with radio/TV/etc. transmitters - and that includes the transceivers in squad cars. The knowledge may be similar, but the focus is different. Transmission power levels range from Ham QRP transmissions of 5 watts or less up to commercial FM transmitters of ~300KW. The larger rhombic antennas will handle 100KW.
In my case, I currently hold a GROL license, although back when I took my tests in an FCC office in NYC, there were 1st, 2nd, and maybe 3rd Class Radiotelephone licenses with various added certifications such as radar. One minor point: even though I hold an EE degree, that degree gives me no rights either as a ham or as a GROL technician. An EE degree only makes taking the appropriate radio tests easier. The FCC controls both the ham and GROL licenses which have evolved over the years. At one point, I was familiar with the "Unlimited" ham license which is now the Amateur Extra Class, (I think).
At any rate, whether for a hobby or for your employment, the world of radio can provide many interesting avenues of exploration. You will find that the Hams are just as passionate about their radios as flashaholics are about their flashlights.
