TYT's new MD-446 DMR Handheld transceiver offers radio amateurs the opportunity to explore the new world of digital communications at an affordable price.

Like all DMR radios, the MD-446 employs Time-Division Multiple-Access (TDMA) digital technology to double the number of users on a single 12.5kHz channel. By adopting the Digital Mobile Radio (DMR) Tier 2 Standard protocol, it is compatible with the popular Motorola MOTOTRBO series DMR radios, as well as any other units which conform to the same standard.

RF output power is 5 Watts RF, and two antennas (9.5 & 3.6 cm) are supplied along with a drop-in charger and belt clip. The radio has a full colour display and is supplied complete with a USB programming cable and software CD.
