Yet another question! Can you tell me how far apart you need the radios apart in order to use the Repeater and how close do the radios need to be to the repeater for them to communicate (is it 200km)?

CJ, Chopper is pretty right, there are some varaibles though.
The quality of your gear ( gain and directional or omni) the mounting of the antenna, the locatiuon of your mobile or base. They are a little better than line of sight. That being said, I have spoken to Tasmania (Tasmanian repeater) from south western Victoria and have had good use of a repeater to cover 180 kms from point to point with one that used to be based in the
Otways.
The distance vary so that there is extended range on the trailing edge of high pressure system, but can be shortened by rainfall, but good where the distance is over water. We hear a business 130-150 kms away point to point with no repeater in summer time to our mobiles (tractors and 4bys). Some other terrains restrict transmission too, as do radio and antenna faults!!!
