Both systems have control channels in the 164 to 166 range. I did not know which system to program in or use. Planning ahead for my next scanner purchase. Wanting to DMR upgrade as well for Edgefield County.
The site listed as Savannah River Site is the only one active. The one listed as Department of Energy no longer shows up. Hope this answered your question
Do you know if Centerra operates off of the same system? I would assume that they are encrypted. One of their 2 helicopters are logging hours on a daily basis. I was able to receive them one time when using 122.8 on approach to Aiken Municipal.
