The lack of signal between walkie-talkies is mainly due to frequency issues and has no direct relationship with the brand of the walkie-talkie. So how can we let different brands of intercoms exchange signals? There must be the following prerequisites.
First, have the same frequency
The premise of the intercom intercommunication signal is to modulate the communication frequency set between the machine and the same. Before different brands of walkie-talkies, some may have the same frequency band, so after adjusting 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 interphone frequency bands. If there is a common frequency value, the frequency value can be set to be the same, and the intercom can also be performed.
Second, within the same signal coverage
Can receive signals to communicate. If not in the signal range. Even if the frequency is adjusted to the same, it cannot be communicated. If the signal is insufficient, consider enhancing the signal and purchasing equipment at this time. Or standing in a high place, the signal may be better.
Third, the same key (sub-tone)
Some advanced walkie-talkies, for the sake of communication security, set security keys for communications. Only use the same key at both ends. This is a different case of neglect. We often overlook this issue in many cases.
It is not difficult to see from the above three points that different walkie-talkie brands can communicate with each other as long as they satisfy the above three points at the same time and realize intercom communication functions.
