Jeff, that's interesting about the Lancaster Co SC EMS frequency. I monitor it also, as I regularly travel highway 521 from highway 75, north to Charlotte most mornings. I had heard that "plan" stuff, and didn't know what it was. I also go to the Wilmington area often , and am familiar with Acme-Delco area. I use an Icom 207H dual band transceiver, with PL tones programmed, so I don't hear too much other than the Union Co NC and Lancaster Co SC agencies........
