LT-990 Mobile Radio Station

Our LT-990 mobile radio station supports frequency band from VHF136 -174 MHz, UHF 400 - 470 MHz and 450 - 520MHz. With audio compander, our mobile radio station could effectively improve the signal/noise ratio, while audio scrambler could encrypt the information. Meanwhile, the power output of our product can be switched from high to low. Besides, multi-scan mode, busy cannel locked and TOT Time-out timer are also supported by our product. Our product also supports PC programming, which makes it fits closely to your custom needs.
