Brian is correct about the BCD250 not being able to trunk-track the York County P25 system.
If you are in the Indian Land area, I would suggest monitoring both the Newport and Lancaster sites for the Palmetto 800 system. As you travel south on Hwy 521, radio affiliation moves from the Newport to the Lancaster site.
Someone else may have more information, but I haven't heard LCSO suing the Pal 800 talkgroups attributed to them in the RadioReference database, or seen any of the officers carrying 800 handhelds. The employees of the county fire office do use the county's 800 conventional channel for chit-chat.
On Palmetto 800, I primarily monitor the following talkgroups:
- SCHP dispatch and tac
- regional government
- mutual aid
- Lifenet
- SHEP
Stations 5 (Van Wyck), 10 (Indian Land) and 14 (Pleasant Valley) are the fire stations (from south to north) in the Panhandle. Stations 10 and 14 pull alot of structure fire, alarm and first responder calls together.
Fort Mill responds for any alarm calls involving the IL schools. Wesley Chapel and Waxhaw FDs (Union County), as well as Carolinas FD (Mecklenberg Co), will also respond on some calls in the Panhandle area of Lancaster Co.
When Lancaster fire depts respond to calls in York County, monitor 155.535 / 127.3 R. York Co patches their working fire talkgroup to this conventional repeater for interoperability. The repeater is also used when Med Center Air, out of Charlotte, responds to a patient transport in York Co. When the conventional repeater is not in use for interoperability, York County EOC will sometimes broadcast amber / silver / weather alerts and BOLOs to those monitoring the channel.
Lancaster Co EMS 4 and Indian Land Rescue are the primary ground medical responders in the Panhandle. LifeNet and Med Center Air are the primary medical helos serving the area, with MCA taking most of the IL calls due to their proximity. LCEMS radios have MCA's VHF channel - 155.325 / 91.5 - in their radios. LifeNet operates on the Pal 800 system, but has the ability to come up on VHF to work LCEMS's channels.
