What is Transmit Interupt

The transmit interrupt feature is a functionality in two-way radios that allows a user to interrupt another user’s transmission, even if they are currently transmitting.

This feature can be useful in emergency situations or when urgent communication needs to take place.

How Does it Work?

When the transmit interrupt feature is activated, it temporarily suspends the ongoing transmission of another user and allows the interrupting user to transmit their message.

Once the interrupting user has finished transmitting their message, the original transmission resumes automatically.

The transmit interrupt feature typically requires both radios to have the functionality enabled, and the interrupting user must have a higher priority level than the user being interrupted.

Priority levels can be set up in advance or dynamically assigned based on the situation.

Benefits of the Transmit Interrupt Feature

The transmit interrupt feature offers several benefits, including:

  1. Quick Communication in Emergency Situations: In emergency situations, time is critical, and quick communication can be the difference between life and death. The transmit interrupt feature allows users to interrupt ongoing transmissions and transmit urgent messages without delay.
  2. Priority Communication: The feature allows users with higher priority levels to communicate their messages quickly and effectively, even when other users are transmitting.
  3. Increased Efficiency: The feature can help increase communication efficiency by minimizing the need for users to wait for ongoing transmissions to finish before transmitting their messages.


The transmit interrupt feature is a useful tool for quick and efficient communication in emergency situations or when urgent communication needs to take place. If you are considering purchasing two-way radios for your organisation, make sure to inquire about the transmit interrupt feature and how it can benefit your operations.
