How many UHF frequencies can the RMU store?

The RMU, or Radio Management Unit, is designed to store multiple frequencies for ease of access during operations. In the context of UHF frequencies specifically, the RMU has the capability to store 20 UHF frequencies. This is crucial for users who may need to quickly switch between different communication frequencies without having to manually tune each time, allowing for more efficient and effective communication.

The design and functionality of the RMU aim to enhance operational efficiency, particularly in scenarios where various channels must be accessed rapidly. Recognizing that the RMU has this capacity helps in understanding the limitations and capabilities of communication systems in aviation and related fields.
