There are two 5-channel Smartzone sites used to fill in the Steele Creek / W Mecklenburg areas where the Tyvola Rd & Bellhaven sites don't reach. They are known as the Red-Fez & Southwest Sites.
There is a new 28-channel simulcast site on the new radio tower at Southpoint in Gaston Co. that will replace the 2 smartzone sites. The Southpoint site was to be up & operational by late Tuesday, but i'm not sure it's 100% yet. There was extensive testing Monday afternoon, as was obvious by the sound of the simulcast system in the pineville area.
If all goes well, i would imagine the Red-Fez & Southwest sites will be shut down completely by the end of the week, if they aren't already.
By this time next year another 28-channel simulcast site (the 8th one i think) is planned for the Cabarrus Co. tower at Albemarle Rd & Flowes Store Rd, to fill in a MAJOR gap in coverage in the Mint Hill, Harrisburg Rd, E mecklenburg Co. area.
To my knowledge there are 28-channel simulcast sites at...
1. /\/\ Radio Shop @ 85 & Sugar Crk (Prime Site)
2. Babe Stillwell Farm Rd tower
3. Tyvola Rd tower (near Closeburn Rd)
4. Uptown
5. Monroe Rd & Matthews Twnshp Pkwy
6. Bellhaven Blvd
7. (new Southpoint tower in Gaston Co.)
