Features:

1. Extended Range: Through the MMDVM hotspot box, regular digital walkie-talkies can achieve nationwide interconnection, tremendously extending the range limitation of conventional digital walkie-talkies.

2. Quality Components: The MMDVM motherboard employs imported components and temperature-compensated crystal oscillators, guaranteeing stable performance and a low bit error rate even after long durations of use.

3. Optimized Layout: The layout and wiring of this board is thoroughly optimized. With minimal heat generation and quick dissipation, it is ideal for prolonged utilization.

4. Multiple Modes: Supporting DMR, D-Star, YSF (C4FM), P25, NXDN, and POCSAG modes, our MMDVM hotspot offers enhanced stability and improved sound quality recovery. Slight fine-tuning allows users to achieve the same stability across all these modes.

5. 3.5 Inch Color Screen: Equipped with a 3.5 inch color screen, this device ensures easy operability and monitoring of functioning.
