A HAM license realistically is for two things:
1 the test teaches you major items you should know about how radio works 2 how to not fuck shit up for everyone else
For the bands allocated to HAM radio in the US, as long as you’re not fucking shit up for everyone else the FCC doesn’t really care. A good example of that and my personal favorite rule is the power transmission rule of “only enough power to complete the transmission”. Functionally it’s so vague that I doubt anyone would ever actually get their license suspended over it.
The group AFRL ARRL has a pretty restrictive “band plan” that I think is where the above comment’s salt is coming from. A perception I have and have heard others talk about is the HAM community has a tendency to be borderline hostile to newcomers and are very gate-keepy, which ARRL in my experience embodies.
I have a license purely to play by the rules from a legal standpoint when I’m out in the rocky mountains hiking and camping with friends, makes communicating with different groups way easier
Edit: formatting, typoing ARRL
Lol whoops yeah, ARRL. I work in aerospace where we love our alphabet soup and I brainfarted AFRL.
I wasn’t trying to say that the band plan doesn’t exist for a reason, it absolutely does, some reasons which you pointed out exactly. I’ve definitely been around guys who treat the band plan like it is the law, and I imagine the original commenter had the misfortune of running into one of those guys and believed him at face value. Imho it’s one of the reasons ham radio has been dying as a hobby.
