State Frequencies
Most State agencies are using Southern Linc for radio traffic.
DPS (State Troopers), Forestry, Marine Police and Game and Fish still
use the VHF frequencies listed in the RR database and Police Call.
The best way to find unknown/unused/private State frequencies to is take the list from here and Police Call and plug them in your scanner and then just listen. Not the most productive way but at least you will have a chance to catch some new traffic. After 16 years with DPS, I still do not have a "complete" list of State used frequencies.
