General units in the application of walkie talkies value instant response communication in walkie talkie communication. Pressing PTT to speak and receiving other walkie talkies with the same frequency within the signal coverage range of the transmitting walkie talkie achieve fast voice communication and meet efficient work needs. In the widespread application of walkie talkies in various industries, it is necessary to have high communication requirements targeting individuals and affiliated groups, reducing interference with other people and groups in the communication unit, and affecting work efficiency. This requires walkie talkies to have their own number and affiliated group number to achieve targeted communication needs.
In fact, in the era of analog walkie talkies, various signaling methods (such as DTMF, 2TONE, 5TONE, etc.) can also be added to higher-level walkie talkies to meet the requirements of individual calls, group calls, and group calls between walkie talkies. However, the application in analog walkie talkies is relatively complex and the usage atmosphere is relatively low.

Now that digital intercom applications have become mainstream in the market, do they all have the function of intercom ID? The answer is yes. Due to the scale sampling and coding application of digital technology, each digital walkie talkie is easier to configure with ID encoding function. In fact, each transmission includes its own ID code, which is easy for the receiving system to recognize, manage, and apply, providing basic conditions and guarantees for ID identification and digital cluster application of digital walkie talkies. This is also one of the advantages of digital walkie talkies.
Digital Walkie Talkie ID
The ID of a digital walkie talkie contains its own information in each transmission, so during the programming process, it is necessary to set the self ID and group information set in the application to which the walkie talkie belongs, so as to facilitate the display and management of relevant information on the receiving end. This is a problem that needs to be noted in digital walkie talkie programming. Before programming applications, we need to understand the specific application situation of the unit. Only by correctly setting the ID and group information can we achieve various subsequent management and applications.

The above is the setting interface for the ICOM IC-F3108D/4108D digital walkie talkie from Japan. To achieve selective calling, setting the frequency alone is not feasible. It is necessary to set the Unit ID, individual calling, group calling list, mute form, and button settings for each machine to achieve the corresponding functions.
