Having seen quite a few of Kelly's posts over the past couple of years, I might speculate his attitude is showing because STA questions are pretty basic stuff. All of it is based in the rules, all of which you can find with a simple Google search. By simply typing in "FCC STA", the first result takes you right to an FCC page that lays out several options that Brian could have used, and probably learned something at the same time. Fair or not, to post something like that here points toward his general knowledge level, for starters, and kind of takes the easy way out. I've talked with Brian a time or two, and I think he's on the right track, but he could have figured this one out himself pretty easily without dumping it on the brain trust here.
I also think it's generally incorrect that most broadcasters don't have a clue about the rules. That's a fairly broad statement that's a bit offensive, given that guiding stations through compliance issues is, for some of us, our jobs, and we take that seriously... at least the engineers I work with do. It's about like saying most pilots take on their profession but don't bother to keep up on their rules. That's a real confidence builder which also is untrue, though there are a few out there who are less diligent than you'd like them to be.
That said, I am somewhat close to a couple of groups that could care less about rules, but their operations show it, and it wouldn't surprise me if they get a visit some day. On the other hand, from large broadcasters in Seattle, to small, rural Mom & Pops on the East side of our state, I work with and know very responsible broadcasters who are diligent about being compliant and protecting their licenses. In my travels, the good ones far outnumber the bad.
