Radioddity GD-88 DMR & Analog 7W Handheld Radio, VHF UHF Dual Band Ham Two Way Radio, with APRS, Cross-Band Repeater, SFR, 300K Contacts

... allows a smooth transition from communication with conventional analog radios to digital DMR (DMR Tier II) at any time. It also comes with dual-standby to monitor two channels at the same time..
Cross-band Repeater Function | Working as a base radio to extend your talking range, it is capable of transmitting on one frequency band (UHF/VHF) a receive a signal on the other frequency band (VHF/UHF). Compared to traditional cross-band repeaters, can cross-band repeat from an analog band to a digital one (or from digital to analog.).
Same Frequency Repeater (SFR) Function | Using just one frequency for transmitting and receiving gives it full use of the DMR TDMA-technique by using one timeslot for receiving and transmitting the received signal on the same frequency, but using the second timeslot, acting as a Same-Frequency-Repeater (SFR). Multiple GD-88’s within a certain area can create a mesh-network, allowing single-VFO radios to communicate with other radios bridged by several GD-88’s that are operating in SFR-mode. The GD-88 is must-have radio for emergency situations where conventional communication systems are limited or unavailable..
