Many years ago It used to be PD and FD only for me, but then I learned there is a world out there and a lot is still available with the right equipment. It seems when one thing either goes away or changes(short wave, encryption, digital) something else comes out to replace or improve..little did we think 10 years ago we would be able to track planes and even ships online.
As far as a ham license, not necessary although I have had mine for years and by working on various classes of licenses it does increase your basic electronics knowledge and exercises your mind and it used to be in some states you could not legally have a scanner in your car unless you had a ham or other type of radio license(I think NY was one).
