VIPER is P25 and as such the bandplan is given OTA over the Control Channel. Which means you don't have to enter one into a scanner. So while VIPER does have a bandplan you should not have to worry about it.
There are only 2 bandplans statewide: one for 800Mhz sites and one for 700Mhz sites. And these 2 bandplans are the default bandplans for those frequency ranges.
Your scanner receives these bandplans automatically over the Control Channel so there is no need to worry about programming them in.
