Can different brands of walkie talkies use each other
It is usually impossible to talk to each other.
If signal interworking is to be realized, the following conditions shall be met:
1. Must have the same frequency
The premise of intercom intercommunication is that the communication frequency set between intercoms should be modulated into the same. For walkie talkies of different brands, some may have the same frequency band. After the walkie talkie is written as the same frequency by the frequency writing software, signal intercommunication can be carried out. If the frequency band is different, it depends on whether the walkie talkie has a common frequency band. If there is a common frequency band, the frequency value can be set to the same, and the walkie talkie can also be carried out.
2. Within signal coverage
Only when the signal can be received can the communication be realized. If it is not within the signal coverage range, even if the frequency is adjusted to the same, it cannot be interconnected. If the signal is insufficient, use high gain antenna or stand at a higher place, the signal may be better, or add relay station.
In order to prevent useless signal interference, sometimes the interphone is set to receive sub voice. When the sub voice of the wireless signal from another interphone is different from the received sub voice, the interphone will not be able to communicate with each other.
4. Same format, key or ID
Some walkie talkies (such as digital walkie talkies) will set a security key or ID for communication security. Only the keys or IDs on both sides are consistent. This is a situation that can't be ignored, which is often ignored by everyone.
Different brands of walkie talkies can communicate with each other and realize the function of walkie talkie as long as they meet the above four points at the same time.
