Wow, #4 is frustrating. (Disclosure: am a ham, but not one of the uptight ones. I'm not personally offended when someone breaks the rules, and I'm not gonna run off and call the FCC or something. But I am concerned when they don't seem to know or care why.)

First, I don't know if their interpretation of the rules is correct. For the sake of argument, I'll assume it is. More importantly, most other people in that thread seem to be going along with the idea that it is correct. This is how it reads to me:

Submitter: We're violating the rules and should make this change.

Replier 1: That change would be inconvenient in Seattle so we're not doing it.

Replier 2: It wouldn't work well in Boston, either, so it's a no-go.

Part of me wants to shake them. This isn't 'Nam. There are rules. Whatever you think about the FCC regulations, they're not voluntary, and they certainly don't have an opt-out for "it wouldn't work as well that way". To a first approximation, everyone else using the public airwaves is more or less following the law. If following the law makes your project not work as well, that's your problem. It's on you to fix your project so that it's legal to use.

I'm not one of those old hams who gets hyper cranky about this stuff, but I do understand how they come to be that way. The only reason we can use the spectrum at all is that people are mostly using it legally so that their work isn't interfering with everyone else trying to use the same public resource.
