Hi, I'm very new to this. I have had a Radioshack Pro-67 for many years but never really used it that much. However, I am now interested in listening to Orange County Sheriff's Sector 5 Patrol... International drive area. I have been messing around with it and looking up info but I cannot seem to find the exact specific frequency for just OCSO Sector 5. Anyone know? Or could help me? Thank you!! Lisa
