What does the PP icon on the Kenwood TK-790 Mobile VHF signify?

The PP icon on the Kenwood TK-790 Mobile VHF signifies Programmable Priority. This feature allows users to configure the radio to monitor multiple channels while giving priority to a specific one. When the programmable priority function is activated, the radio will interrupt the ongoing communication on the current channel to check for activity on the priority channel. This is particularly useful for ensuring that critical communications can be received promptly, even when the radio is engaged on a different channel.

Programmable Priority enhances operational efficiency and responsiveness by allowing users to focus on multiple channels without completely losing track of important communications. This functionality is vital in emergency services and wildland firefighting scenarios where timely information can significantly impact decision-making and safety.
