Are you looking for a reliable, durable, and versatile two-way radio that can meet your communication needs in various situations and environments? If so, you might want to check out the QuanSheng TG-UV2 Plus, a dual band radio that can operate on three frequency ranges: VHF (136-174 MHz), UHF (350-390 MHz), and UHF (400-470 MHz). It has a high output power of 10 W, which ensures a long communication range of up to 30 km in open fields, 7 km in forests, and 4 km in urban areas. It also has a large capacity battery of 4000 mAh, which can last for a week without recharging.
But what makes the QuanSheng TG-UV2 Plus stand out from other radios is that it is a superheterodyne radio, which means that it has a special circuit that converts the received signal into a fixed intermediate frequency (IF) of 465 kHz, and then amplifies and detects it. This circuit, which consists of a mixer and a local oscillator (also called a heterodyne), has several advantages over the direct amplification method. First, it improves the sensitivity and selectivity of the radio, which means that it can receive weaker and more distant signals, and filter out unwanted and interfering signals. Second, it simplifies the design and operation of the radio, because the most critical parts of the receiver (the narrowband filter, the IF amplifier, and the demodulator) do not need to be tuned to different frequencies when switching to different radio stations. They can be fixed and optimized for the intermediate frequency, which is always the same. Third, it allows the use of external antennas and repeaters, which can enhance the signal quality and range.
The QuanSheng TG-UV2 Plus is not only powerful and smart, but also sturdy and durable. It has a rugged design with a level of protection from dust and water of IP 56. It can withstand harsh environments and temperatures from -25ºC to 65ºC. It also has a jacklight function, which can illuminate the dark areas. The radio has a high-quality speaker and microphone, which deliver clear and loud sound. It also has a CTCSS/DCS function, which can filter out the unwanted signals and reduce the interference. It also has a battery saving function, which can extend the battery life by reducing the power consumption.
The QuanSheng TG-UV2 Plus is easy to use and customize. It has a monochromatic LCD display with backlight, which shows the full frequency, channel, and frequency information. It also has a voice prompt function, which can be set to Chinese or English. The radio has 200 programmable channels, which can be easily set by using the PC software or the keypad. It also has a built-in FM radio, which can receive the broadcast signals from 88 to 108 MHz. The radio has a VOX function, which allows hands-free operation by voice activation. It also has a priority scan function, which can monitor two channels simultaneously and switch to the one with a signal.
The QuanSheng TG-UV2 Plus is a great choice for anyone who needs a powerful and versatile two-way radio. It can be used for various purposes and scenarios, such as amateur and professional radio communication, car, hiking, fishing, sports, and home use. It can also work with external antennas and repeaters, which can enhance the signal quality and range. The QuanSheng TG-UV2 Plus is a radio that will not disappoint you. It is a radio that will make you feel the power of superheterodyne.
