New Hanover Co
A couple of years ago, I was listening to them one night when they started having problems with the 800 system. I heard a WPD telecommunicator tell all units to switch to "10-C". After doing some searching and checking the FCC database, I found them on the GE Plant 800 system in Castle Hayne. Further searching also found some New Hanover SO units on a talkgroup on the New Hanover Regional Medical Center 800 system. Since Horry Co and Onslow Co are the 2 closest 800 systems to Wilmington and probably too far away for backup purposes, I guess that's why they set it up to use 2 local 800 systems for backup purposes. I know there is a talkgroup on the GE system for plant security along with some maintenance talkgroups and the NHRMC system is similar. Could these be what you are hearing or, reading another post, are you refering to the Seabreeze site? The Seabreeze site, to me, is kind of screwy. I believe its purpose was to provide coverage to the lower end of the county but instead of making it a simulcast site with the same frequencies and talkgroups, they went with different frequencies and talkgroups. However, the dispatch talkgroups on the primary tower and Seabreeze carry the same traffic, they just have different ID's depending on the tower. From what I understand, they are going with a new P25, 9600 baud system and that system will have simulcast sites, including one at Seabreeze.
