In the 1930s, the word “walkie-talkie” was often assigned to any receiving station. Now this word means a mobile or portable transceiver device, which is designed for online communication.
Radio (walkie-talkie) – a useful device for communication in hiking, climbing mountains or traveling on rivers. The choice of such a device must be taken seriously, because a walkie-talkie can save lives in a difficult moment. In this oversight, we will consider the radio BaoFeng UV-9S.
Almost all BaoFeng walkie-talkies have great functionality, compared to the Walkie Talkie. The BaoFeng UV-9S transmitter has a power of about 8W, which allows for good communication at a range of up to 10 km. in hills / forest. If it is necessary to transmit a signal of more than 10 km, you need to buy the appropriate antenna.
The UV-9S walkie-talkie has a monochrome display with backlight options, which allows you to quickly adjust the walkie-talkie itself and the frequency range of reception / transmission. Data-cable and program are required for more fine-tuning CHIRP.
CHIRP is a free, open source tool for programming walkie-talkies. The program supports many manufacturers of walkie-talkies, as well as provides a way to interact with multiple data sources and formats.
The walkie-talkie is based on BaoFeng UV-5RX3 (but this is not true). The transmitter with a power of 8 W allows to receive a signal at a satisfactory level up to 10 km, and in urban development – up to 5 km. (depending on the antenna).
In addition to VHF and UHF frequencies, the walkie-talkie has an FM frequency range for reception. Because the battery has a large capacity, such a receiver will last for a long time.
BaoFeng UV-9S ranges
FM: 65-108 MHz (reception)
VHF: 136-174 MHz (receive / transmit)
UHF: 400-520 MHz (receive / transmit)
Number of channels 128
СTCSS codes (possibility of combination with any LPD radio station)
DCS codes (expand the possibility of combination with other radio stations)
Frequency grid pitch, kHz: 2.5 / 5 / 6.25 / 10 / 12.5 / 25KHz
If you often go to nature, lead an active lifestyle and travel – you need to have such a reason.
