“I have found a new trunk system in NB it is run by Atlantic Communications,
 it covers all of southern NB, their site says it is part of system that covers HRM,
 I believe that this system has no ties to Aliant. I believe that it is used 
 primarily by commercial users, it uses the MPT1327 trunking scheme the same type
 that the OPP use so it can't be tracked by trunktrackers. But if you use a ctcss 
 tone (their tone is 238.0???) it eliminates the computer noise and you can hear the
 traffic. I believe that these systems use one tone for the whole system (like OPP)
 this:   http://www.atlantic-communications.ca/news.html   has a system description.
 According to Industry Canada one repeater has a range of 160 km, transmitting at
 30 watts, quite high for UHF. More to come. Frequencies and Map link below” 

 Map of system coverage:  http://www.atlantic-communications.ca/mpt.html

 Simplex in all areas: 418.6625.  Note the unusual mixture of low and high
 UHF frequencies and the re-use of some frequencies,but not all, between sites.
 Control channel information not known.  Please send any further information you
 may have.
