Duplex Version Mini MMDVM Modem Portable MMDVM Hotspot Assembled w/ Pi-Star System for Mobile Radio

Description:
There are two options for you, i.e. simplex version and duplex version.

It is an MMDVM modem hotspot box. Through it, you can use ordinary digital mobile radios to achieve nationwide interconnection, which solves the limitation of the communication distance of ordinary digital walkie-talkies!

PI-STAR system makes it convenient for your habits.

MMDVM motherboard is designed with all imported components and TCXO. After a long time of booting, its performance can also remain stable, and the bit error rate is low! This is the new version of MMDVM duplex 2-slot digital hotspot. We have optimized the wiring for the board. The component layout is perfect, the heat generation is small, and the heat dissipation is fast. Thus, it's suitable for long-term operation. The duplex board has the advantage of double time slot for DMR, and all debugging parameters are carefully debugged according to the DMR standard. The calibrated DMR system will be more stable in use, and the sound quality will be greatly improved. As for other systems, users only need to trim the frequency offset slightly. Its performance is also stable when it is used in DMR, D-Star, YSF (C4FM), P25, NXDN and POCSAG modes.
