[bars] ***SPAM*** Re: GMRS

[Christopher Lennon]

So, think of it from the standard GMRS user's point of view.  They just
want to use radios to communicate with friends/family while doing stuff.
They don't care about the radio.  They don't care much about rules except
that if they use the equipment that a licensee hands them and use the
licensee's call sign they are within them.  They have their very own little
piece of spectrum to do this sort of comm.  The usual GMRS user would have
ZERO interest in the conversation we are having now.

So why would GMRS users want to invite in a bunch of radio nerds who want
to talk about radios and rules and whether they will get a haircut today?

Really, it is best to keep these worlds separate.
