First off!
Go to the Viper Section of the Database under North Carolina
Scroll down and you will see just about all the active Viper Sites listed
It maybe a little Out-Dated, but Marshall does a darn good job of trying to keep it updated.
MY HATS OFF TO HIM
No offense Greg, does a good job as well.
Anyway, look for the Altmawhaw Site and the Cane Mtn. Site. Both are covering Alamance County
Look at the frequencies and the ones that are highlighted in Red should be the Primary Control Channel and the Blue should be the Secondary Control Channel.
The same is true for the Yanceyville Site in Caswell County as well.
I was told there are 64 Control Channels for Viper across the State. I was also advised this number would drop to 32 Control Channels once the rebanding has been complete.
Just my thoughts
