This is customized product, you need to tell us which frequency you need when you make order, it needs about 2-3 weeks to produce fit item for you.
NOTE:
UHF Band Duplexer should be 10MHz
The difference between Transmitting Frequency and Receiving Frequency for UHF Band should be 10MHz Maximum due to the duplexer exists(For Example, TX:439.2MHz, then the RX frequency should be :429.2MHz maximum).
VHF Band Duplexer should be 5.7MHz
In order to reach the best communication effects, the Frequency difference between TX and RX for VHF Band Duplexer should be 5.7MHz due to the duplexer exists(For Example, TX:136.675MHz, then the RX frequency must be 142.375MHz ).
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.
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.
