As a general rule, FCC doesn't seem to give out denials as long as you show some semblance of understanding what's going on and act in good faith.
I
have seen people misunderstand a return letter as being a denial.
Return letters aren't good, but they do ask questions like "Are you really a business? What kind of business are you?" and more formal phrasings of "Why do you have 128 radios over 16 channels at 50W each across every state in the union when you wrote that you're a sole proprietor doing software development work? Also that frequency has a 35W limit. Please don't.".
Yeah, that kind of thing.
FCC just
really really likes their forms. Fill it out right and you'll get the license.
Fill it out inconsistently or wrongly and you'll have someone telling you exactly what you did wrong in formal language, which i suppose can be intimidating if you're not used to it.
Another thing was everyone wants all 50 states but probably doesn't actually need 50 states.
FCC put together a group to figure out why the hell everyone wants 64 radios and 50 state itinerant usage and to try and limit it a bit more geographically (like the three local states).
FCC doesn't understand the concept of trying to avoid future paperwork because paperwork is love, paperwork is life.
Edit: If ApacheScout got a denial, he'd be the only one I've ever even heard of when applying for itinerant part 90s (which doesn't preclude people here getting one and not telling me).
