I should add that many agencies that operate in Metro PD's jurisdiction do have the capability to come up on the LVMPD basic radio channels if they have a VHF radio in their vehicle. In past years the tribal police did come up on Metro PD channel 1 (159.150 MHz).
Another case in point, the NHP vehicles for the most part do have their old VHF high band radio in the vehicle and do access the LVMPD radio system from time to time. This happened as recently as today in the rurals. Enjoy your trip.
