DMR Digital Direct Mode (TX = RX same Frequency) Repeater
RPT-810
DMR Digital Repeater (DMO)
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.
The RPT-810 product is fully compliant with ETSI-TS 102 361. It provides standard DMR co-frequency simulcast to achieve smooth digital repeater operation.
Features
- Adopts 2.8" HD TFT LCD display for a good visibility.
- Innovative Auto-protecting Technology.
- This feature ensures the radio work normally, when the loader is not matching (abnormal SWR and unmatched current, etc).
- High/Low Power Switchable.
- Supports two voice calls simultaneously in direct mode.
- Featured with advanced noise reduction which makes the noise suppression be up to 25 dB.
- DMR Tier II Conventional and DMR Tier III Trunking.
- Input voltage can be set at 90VAC ~ 264VAC 50/60Hz.
- UL listed to both USA & Canadian safety standards.
