San Joaquin County (CA)

From N5FDL:
The big things that are happening in the county is the gradual shift to P25 for law enforcement agencies (on UHF) and the move by fire agencies to narrowband VHF frequencies. There has long been a plan to move all public safety agencies in the county to UHF, but that does not seem to be moving forward very quickly.
At this writing (4/20/09), the fire frequencies are not changing at the rate they were a year ago. Yes, there is a Control 3, but the frequency and tone are likely to change. One thing you may not have noticed with SJ fire channels: The odd-numbered channels are north county and the even-numbered channels are south county.
