32112 is used by SCDOT roadside assistance (formely SHEP) as a talkaround channel. It is not part of the SCDPS radio plan. The trucks call it "Ch.1". They are dispatched on 20848.
EVAN: 12- 21456 Mutual Aid-1 / 13- 31280 Regional - 1 Does this look correct. Pickens and Oconee Co EOC tested the 31280 a couple of weeks ago during a state operated comms test. Pending any reply, Larry
Yes, that is correct. I'm not sure why counties in the upstate were using that talkgroup. It is often used by counties in Troop 1 (such as Clarendon) to pass information to HP.
