The Retevis RT73 Dual Band DMR Mobile Transceiver is a compact yet highly capable mobile radio designed for amateur radio operators, vehicle installations, and professional communications. Supporting both DMR digital and analogue modes, the RT73 combines dual-band VHF/UHF coverage, built-in GPS, dual time slot operation, and up to 4,000 programmable channels in an ultra-compact mobile form factor.
