Is it difficult to get your license?
There is a test, and depending on the level of license you want, it gets more difficult.
A technician’s test is the easiest but it requires some rules/regulations knowledge and a very basic understanding of electronics and computer tech as it relates to communications.
The next level up is the general license, and it requires a more moderate level of knowledge in those areas.
The highest level is the Amateur Extra license, which is the most difficult to pass. I scored less than 50% on that exam - took it at the same time I took the general license exam. Studying is necessary, but there are aides for studying and learning.
Each higher class of license allows you access to more frequencies and possibly greater broadcast power.
