There is no signal received between the walkie-talkies, mainly because of the frequency problem, which has no direct relationship with the brand of the walkie-talkies. So how can we communicate signals between different brands of walkie-talkies? The following prerequisites must be met.
1. have the same frequency
The premise of the interphone intercommunication signal is that the communication frequency set between the two machines should be modulated to be the same. Before different brands of walkie-talkies, some may have the same frequency band, so after they are tuned to the same frequency, they can communicate with each other. If the frequency bands are not the same, it depends on whether there is a common frequency value between the frequency bands of the walkie-talkie. If there is a common frequency value, then set the frequency value to the same, and the intercom can also be performed.
2. Within the same signal coverage
Only when the signal can be received can they communicate with each other. If not within the signal range. Even if the frequencies are tuned to the same, they cannot communicate with each other. If the signal is insufficient, you can consider enhancing the signal and purchasing equipment at this time. Or standing high, the signal might be a little better.
3. The same key (sub-tone)
For some advanced walkie-talkies, for the security of communication, a security key will be set for the communication. It can only be used if the keys at both ends are the same. This is a different case of neglect. This problem is often overlooked by many people.
From the above three points, it is not difficult to see that different walkie-talkie brands can communicate with each other as long as they meet the above three points at the same time, and realize the function of intercom communication.
