On second thought, I would highly recommend for anyone using the G4 or G5 on the VIPER system that they enable full spectrum control channel search and use the following tables:
Start: 851.0125
End: 860.9875
Step: 12500
Start: 769.00625
End: 774.99375
Step: 12500
Still keep the control channels for your local sites programmed in so it will acquire faster (the pager looks at this list first) but in the random chance that frequencies are changed there is still the ability to search for a new control channel without having any intervention or reprogramming. As long as your site numbers are programmed (1-02, & 1-53) the pager will search until it acquires a control channel on one of those two sites in Johnston County. Scroll down or use the diagnostics menu to display the current frequency and update your programming for faster acquisition and post an update so the database can be changed to benefit others. This method has worked well for me and is setup on all my VIPER & Palmetto personalities.
