Features:
1Enabling Nationwide Interconnection: Using ordinary digital radios via duplex hotspot board enables nationwide interconnection, solving the limitation of the connection distance of ordinary digital radios. 2Stable Performance: The duplex hotspot board uses imported components and temperature supplemented crystals for stable performance over long start up times and low bit error rates. The upgraded MMDVM duplex dual time slot digital hotspot has the advantages of optimised wiring, perfect component layout, low heat generation and fast heat dissipation, making it suitable for long start up times. 3Multidirectional Installation Possible: The duplex hotspot board is reserved for 2 (old and new version interfaces) Organic Light Emitting Diode screen interfaces and 1 NXT serial screen interface, allowing for multidirectional installation and making the screen more personalised. The small board uses a PCB antenna and also reserves an external antenna interface. The duplex board has the advantage of a for DMR dual time slot. 4High Stability: All commissioning parameters are based on the for DMR system. Each duplex hotspot board has been carefully tuned. A calibrated for DMR system will be more stable in use and the sound quality reproduction will be greatly improved. As for other systems, with a slight adjustment of the frequency offset, the user can use the same level of stability. 5Multimode Use: A calibrated for DMR system with a duplex hotspot board will be more stable in use, and the sound quality reproduction will be greatly improved. As for the other systems, users can use them stably for DMR, for D Star, for YSF (C4FM), for P25, for NXDN, for POCSAG and other modes with a slight adjustment of the frequency offset.
