I am unaware of them using any type of alpha paging system.
Must agencies today have calls routed to thier smartphones and other type of electronics (i.e. MDT's,etc).
I think the only agencies in this immediate area that still uses alpha pager is Mecklenburg & Gaston Counties.
Like Daniel said, if you do have a radio programmed for those 800 Mhz. the best thing to do is get it unprogrammed and quick, because I got in trouble one time myself working with the City of Charlotte.
Word got out that I had a personal 800 Mhz. radio on the Charlotte TRS. Well at the time the Charlotte Fire Communications Director came done and thout that since I had a personal radio programmed with CFD, she automatically assumed it was there system.
Well to make this short, Chris Linker (Who is no longer with us) stepped in and told her that he programmed the City of Concord radios the same way with CFD which stands for Concord Fire. Needless to say that clear me of all wrong doing.
Also FYI, there are no current Amateur Radio frequencies in the 800 Mhz. band range. There however are Amateur Radio frequencies in the 900 Mhz. band.
As far as the Char/Meck 800 Mhz. system they are using both analog and digital for communications. I listen to my analog scanner at work and I can pickup dispatch and the Ops channels and SHP real good. I have one of the new Uniden Digital Scanner as well I will occasional turn it on and listen to Meck on the digital side too.
Charlotte/Mecklenburg has a long standing rule that NO PERSONALLY OWNED RADIOS will be allowed on there system. I have fought this battle before, when Concord/Cabarrus signed on to be apart of the Char/Meck Digital System. I lost 8 personal radios from the Concord/Cabarrus system. So needless to say I have a shop full of paperweights that are useless except for programming the National Public Safety Channels in.
So the only real way to get an 800 Mhz. radio on the Char/Meck system is to join a Mecklenburg Agency and hope they will provide you a department owned radio. I would kind of doubt that all Mt. Mourne members would be issed a radio on the Mecklenburg system. They probably have a mobile and a portable that is issued to the department with the agreement that the radio stays with the apparatus. I can't say for certain if there members are all issued 800 Mhz, radios for the Morresville System or not.
