Just a comment

I have bought all my radios on-line, how would these systems work here?

Also a LHS, nor the AMA can control that 72 Mhz band, actually if they did, they would find them selves in federal court.

Also would you want to be a LHS owner who gets dragged in to court for a discrimination claim.
(under what basis could the LHS owner for justifying not selling the radio, where the FCC puts no such limits, the FCC grants right of use as long as you accept part 15 (usage = acceptance)).

Rather than make this long I'll end here ( there are many more examples).
