I'm kind of in the same boat although the Motorolla FR-50's I bought 7 years ago still work fine. A little more privacy would be nice but from what I understand the MURS radios use a lot of juice and need frequent recharging. Anyone have real world experience with runtime?
Power use is directly related to power out - you compare a 1/2 watt FRS to a 5 watt MURS - of course the batteries go dead faster
