TYT MD8500 UHF 400-470MHz DMR Walkie Talkie Repeater
100% continuous duty cycle
Integrated heat sink and back panel fan provides the good design for 100% continuous duty cycle at 45W output.
Smart detection analog and digital signal
Mix mode in program software realizes the smart detection of analog and digital signals in single channel.
3U rack mount size
3 U rack mount professional design, with two handles, leave enough internal space for duplexer, possible for desktop or wall mount installation.
100 Memory channels
Channels button and LED monitor design in front-panel offer you the clear indication of 100 memory channels and easy switch operation between different channels.
QT/DQT with multi-decode
The MD-8500 decodes 5 QT/DQT groups in one single channel. This function is useful for sharing a channel with multiple groups.
Bright, clear LED indicate
Up to 8 LED lights integrated in front-panel. It is useful to check the status of operation mode including analog/digital, power level, over temperature status.
Automatic voltage and temperature protection
When the operate voltage, temperature, voltage standing wave ratio exceed the pre-set value, it switches to low power or power off automatically.
Improved audio quality
Ensures the improved audio quality and larger coverage under noisy environment comparing to traditional analog.
