LT-UV4 Amateur Dual Band Portable Radio Transceiver
:image001.jpg
Our LT-UV4 amateur dual band portable radio transceiver features a multi frequency, multi working modes, multi display and multi scanning modes in its 128 memory channels. The frequency range of our radio transceiver is from 76 to108MHz, 136 to 174MHz, 350 to 390MHz and 400 to 470MHz. Meanwhile, the working mode can be selected from U-V, U-U or V-V. The display can be in any of channel number order, channel frequency order or channel name order. The channel scanning modes can also be selected from priority scanning, multi-function scanning, while adding scanning channel is also available in our radio transceiver. Besides, the channels can be set as VHF TX and UHF RX or UHF TX with VHF RX, while the bandwidth can be selected from wide of 25KHz or a narrow one of 12.5KHz. The frequency steps can also be selected from multiple values. The frequency offset can be set from 0 to 69.950MHz, while the frequency shift direction can also be adjusted. Don’t worry about those configurations, for you can simply program our product by your computer. Wire-clone function also enables you to transfer those settings from one to another. The menu and channel can be reset to the original value as well.
Meanwhile, with DTMF encoding, together with 105 groups DCS and 50 groups CTCSS scanning, our product is effective to avoid the collision in the same channel. Voice guide and VOX function could give you verbal instructions and let you control by voice. Meanwhile, thanks to the high capacity Li-ion battery pack, our product could have a longer working time. With a power output of 5W in VHF band and 4W in UHF band, the power consumption can also be adjusted automatically from high to low if the transmission signal is strong. With an intelligent charger and low power alert of our radio transceiver, you need not worry about the power supply any more.
Moreover, our product could be used as FM radio, stopwatch and an emergency alert. With a power on message in its startup, it also offers an automatic and manual keypad lock. If the transmission overtime occurs, it will notify you immediately. Meanwhile, the busy channels could be locked thanks to our busy channel lockout function. Reverse frequency is also used in our radio transceiver.
