dmr time slot

Douglas Herr is well known amongst us who used to use the Leica R system back when it was slide film and when the DMR Digital Back came out

Here is the Baofeng entry to the DMR market this is the DM-1701 dual band (VHF and UHF) and two time slot radio ... I am very satisfied with this radio, and a nice addition to my Ham Shack.

Digital Mobile Radio (DMR) is an open digital mobile radio standard defined by ETSI and used in commercial products around the world. Mostly used by private network and local police, can be encrypted. Used in MOTOTRBO products.

The DMR protocol has two time slots in a 12.5KHz bandwidth, which means that the RPT-810 can be used as a single frequency repeater (SFR), and the RPT-810 DMR radio digital repeater is assigned one slot is used to receive the signal, and the other slot is sent at the same frequency. DFR digital RF signals are forwarded through the SFR single-frequency repeater. The RPT-810 digital repeater, which is equipped with a single frequency repeater (SFR) function as a standard, will send data received in time slot 1 and forward it to time slot 2 traffic. DMR radio terminals essentially function as single-frequency DMO repeaters. Voice or data information is received by the SFR in DMO mode (Direct Mode Operation for short) in the first time slot, and retransmitted on the second time slot (90 milliseconds) almost simultaneously. SFR enables the direct link range between traditional DMR devices in DMO mode to be expanded without having to change the frequency due to the use of repeater repeaters. Using only a single 12.5KHz channel provides greater coverage for radio users.
