How to pair walkie talkies？

The content of walkie talkie matching is divided into three types:

1. Pair with public interphone.

The frequency range of public walkie talkie is 409mhz-410mhz. The operation mode of public walkie talkie of all brands is similar. The public channel is divided into 20 channels, so it can be directly used with the 20 public channels of Xiaomi's walkie talkie, and can be adjusted to the same channel.

Adjust the public interphone channel to 17, which corresponds to the public channel 17 of Xiaomi home interphone, and adjust to the unified channel to talk to each other.

2. Pair with walkie talkie with numeric keypad.

The main difference between amateur walkie talkie and public walkie talkie is the frequency range. The frequency range of amateur walkie talkie is:

144.000mhz-148.000mhz, 430.000mhz-440.000mhz; therefore, it is not enough to simply use 20 numbers to represent it. At this time, you need to refer to specific frequencies.

3. Pair with amateur walkie talkie without numeric keypad.

Compared with the above two situations, the pairing of amateur walkie talkie without keyboard is a lot of trouble. Generally, the frequency of amateur walkie talkie without keyboard is adjusted by a fixed knob, for example, 16 scales of the knob represent 16 channels,

Each channel has a fixed frequency set at the factory. When users use it, they only need to rotate two identical machines to the same channel to talk.
