Today we will focus on the all call function of Retevis RT40.

What is all call function? How to understand the all call of the walkie-talkie?

All call is not commonly used for hams, it is more suitable for commercial use, similar to broadcasting. When the walkie-talkie is set for group calls, this channel can only be transmitted but not received, which is similar to our broadcast, only sending but not receiving. For example, in a company, if the leader wants to post a message through the walkie-talkie, the leader's walkie-talkie can be set to all call. At this time, he transmits and all other walkie-talkies can receive it, even if someone accidentally presses the PTT button to transmit. It will not interfere with his transmission, because it is a all call radio, only transmitting but not receiving, and the priority is higher than other intercom group calls or single calls.

Secondly, the walkie-talkie with the all call function can only transmit but not receive. Only when other walkie-talkies are also set up with the all call function, can they receive the signals from each other. In other words, all call is equivalent to the leadership level from another point of view. Only walkie-talkies with the same level, that is, all call settings, can receive messages from each other.
