I am trying to activate Dynamic Mixed Mode in Mototrbo System. I have Motorola DR3000 repeater, I have more Mototrbo radios DP4800 and more GB300 series and GM series. In fact I tried to configure them by choosing a Dynamic Mixed Mode in the repeater and I configure digital channel and even analog channel on them and when I try to PTT in digital I hear tone as it is busy and on analog I hear voice not clear. Is there anyone can help me in this, please?
In another way, I heared that they use a DM4400 interfaced with the repeater by pins cable. Which way is the true and how step by step, please?
