Mototrbo also allows one to configure the repeater to be either analog, or digital. But once configured for one (analog or digital), programming will be required to switch it. I have overcome this by placing two repeaters within the same cabinet. One conventional, and Mototrbo, both on the same frequency pair. Therefor, it will remain an open system for all to utilize and experiment. At his point, I'm just waiting for the Mototrbo repeater to arrive. > With DStar there is no such option; you have > to plug it in & just accept whatever performance level you get.
