I am curious, what percentage of RR subscribers are "scanner hobbyists" who's only interest is listening to public safety LE related comms vs "radio communications system design enthusiasts" who's interest is in radio models, and system implementation?.... vs actual NYPD subscribers ?..... "Joe Schmoe and his scanner" are important subscribers also, are they not?... Since I have interest in both subjects, I find all of these posts and questions relevant .....just my humble opinion....
Like @GTR8000 said, I think you have RR subscribers and radio "subscribers" mixed up. Subscribers is an industry term for the portable/mobile radios on a system.
I think you will find here on RR that everyone is a hobbyist (we wouldn't be here if we weren't) but there are a certain number of hobbyists that work with radios as all or part of their job. I myself started out as a hobbyist and while my main job is not radios, I am heavily involved in our communications systems. I think many here are in a similar position.
