I would not trust such an old antiquated piece of equipment for my business
especially when you are dealing with human cargo, the liabilities would
worry me very much. I would recommend that you either purchase something a
lot newer, or lease something from a provider (not Nextel) but someone that
has those types of systems in place or that can install and maintain such a
system for you. An old Micor system if fine for an amateur repeater (I have
several compa-stations) but it is not worth your time or trouble to take an
old radio that is wide-band and try to convert it narrow-ban. The specs and
stability of those old micors is not all that great. That is my two cents
worth, speaking both with a little technical knowledge and business
knowledge, it ain't worth it.
