For some people that say it cant be done or I have my information wrong.Converting a motorola gm300 to use it as a dstar reapeater/hotspot.first you need the gm300 that has the 16pin accessory port on the back,your also going to have to homebrew a patch cable to interface the radio with the gmsk dstar modem board.theres also an important jumper that needs to be on the right possition for it to work.to many details so ill post the link.you also still need a dstar rig to use it on the homebrew repeater.
