Thanks RSG, Your info will be of help, guess I will not go for the Rangr. Using 2 radios will increase power usage, and I need to keep this low, for portable use.
As for freq. change, this of course would need the duplexer to be retuned for the freq. required, not that I believe it would be changed much. Just wanted something (radio) that could be changed if the portable repeater needed it. Maybe a close-by repeater had it's RX close to the portable TX freq. The main issue, is that the repeater TX must be low power, max 10 watts, most likely running around this value. Hope this tidies up my previous message.
