Functional characteristics
1 use UHF740-790MHz frequency band to avoid interference frequency
2 automatic infrared to the frequency, the transmitter and the receiver automatic synchronous transceiver
3 using phase locked loop PLL frequency synthesis stable system, provides 200 channels
4 using the most new type of high frequency filter, to maximize the filter out of band interference signal
Two using 5 times the frequency of high frequency circuit design, with a high sensitivity
6 multiple squelch control circuit, refused to open the machine external interference squelch system
7 specially designed speech compression expansion circuit, which greatly improves the signal to noise ratio
8 unique circuit design, dynamic, wide frequency response, low noise
 
True diversity receiver,these transmission systems ensure interference-free
transmission and minimise d ropouts in the RF line，avoid the dead angle
