We use motorolas in the bar building here, similar to ones I've used in the hills when supervising hill walks. On the hills we were able to use them, line of sight, for anything out to 8 - 10 km. Here in a building with similar radios we often have difficulty talking between the bar on the first floor and the basement - just too much interference from the floors, walls and electrics in the building.
