DMR Digital & Analog Professional Walkie Talkie Repeater

 (Built-in Duplexer, RF Output Power 45W,100 Memory Channel)

 

IMPORTANCE:

The difference between Transmitting Frequency and Receiving Frequency for UHF VHF Band should be 10MHz Maximum due to the duplexer exists.

 

Features:

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.

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.
