In the case of Motorola R2 radios, what is the difference between ERDM and DCDM, and are they both for transmitting and receiving on the same frequency, only on a different timeslot? unfortunately, Motorola did not give much information about this. I would like to build and program an SFR simplex repeater. This device is a Hytera MD785i / HM785. And to connect Motorola R2 radios to this SFR repeater, presumably using DCDM. Is this the correct solution for such a system?
1.DCDM no color code but two timeslot
2. ERDM two color code and two timeslot
1.DCDM no color code but two timeslot
