I can confirm the following are in use:
154.8450 [110.9 PL] Curry Co Law 2 (Main Dispatch)
155.0100 [141.3 PL] Curry Co Law 1 (Old Dispatch)
152.0075 CSQ Curry Co Fire / EMS Pagers
155.3250 [110.9 PL] Curry Co MedNet (EMS Working)
154.8750 [110.9 PL] Curry Co FireNet (Fire Working)
156.1200 [110.9 PL] Curry Co Roads Repeater
I'm pretty sure they are simulcast.
As for the city/county stuff I have no idea.
