No. If a P25 repeater goes down, you can have a 'mode' (as Moto calls it) that is simplex on the output, and you will be still be heard by any radios in range-IF you're on a conventional system. A trunked system is different, but the radios do still have conventional simplex available, and should be programmed. D* I expect has the same thing. I don't think there is a direct radio-to-radio mode in Mototrbo...I could be wrong tho...
