It's a retvis RT90 DMR radio. It's definitely not supported, nor do I think it will be supported by Chirp in the future.

Digital radios aren’t generally supported by chirp. It’s just a rebranded Chinacom radio, so your first step is to figure out which actual radio it is, then find the vendor software for that radio and see if it works.

Good morning,

Looking to see if anyone is working on being able to program a rugged radio model RDM-DM dual band radio.   

Thanks you,

Chris
