Motorola Amateur Portable Radio Transceiver
Motorola Amateur Portable Radio Transceiver
Motorola amateur portable radio transceiver features 128 groups of memory channels, whose name can be edited as you wish. Those channels can be scanned in priority scanning or multi channel scanning mode. Moreover, group calling and selective calling is available by our radio transceiver. The optional scrambler could effectively protect your privacy in wireless transmission. Reverse frequency technique is also used in our radio transceiver while automatic numbering identification is used to identify the transmitting user. Equipped with voice security device, VOX function is supported, which could control it by your voice. The voice prompt is also used to deliver instructions to users. Meanwhile, our product could also perform as emergency alarm as well.
The power consumption of our radio transceiver is low thanks to the power control unit and the adjustable 3 color backlit screen. The battery alarm will be activated if the power supply is low. Meanwhile, transmit time limiter is used together with time out timer to control the length of conversation. Busy channel lock can be used to avoid collision with other users. The bandwidth can be edited from wide to narrow, while the squelch grade can be set as well. Those parameters can be programmed by your own computer, thus you can adjust them in an easy manner.
