Baofeng radios, such as the UV-5R, offer two primary modes of operation: Frequency Mode and Channel Mode. In this post we explain differences between the two and their applications.
Frequency Mode (VFO Mode)
Frequency Mode, also known as Variable Frequency Oscillator (VFO) mode, allows you to manually enter and tune to any frequency within the radio’s operating range. This mode is useful for:
- Exploring Frequencies: You can manually input frequencies to find active channels or listen to specific frequencies that are not pre-programmed.
- On-the-Fly Adjustments: Quickly changing frequencies without needing to pre-program them into the radio.
- Testing and Calibration: Useful for testing antenna setups and other equipment adjustments.
In Frequency Mode, you can:
- Directly enter a frequency using the keypad.
- Adjust settings like frequency step, offset direction, and offset frequency.

Channel Mode (MR Mode)
Channel Mode, also known as Memory Recall (MR) mode, allows you to select from pre-programmed channels. These channels have specific frequencies and settings stored in the radio’s memory. This mode is useful for:
- Convenience: Easily switch between commonly used frequencies without manually entering them each time.
- Organization: Group and label channels for specific uses, such as local repeaters, emergency channels, or personal communication channels.
- Consistency: Ensures consistent settings for frequencies, such as transmit power, CTCSS/DCS tones, and offsets.
In Channel Mode, you can:
- Scroll through pre-programmed channels using the channel knob or keypad.
- Each channel can store settings such as frequency, power level, CTCSS/DCS codes, and more.
Switching Between Modes
To switch between Frequency Mode and Channel Mode on most Baofeng radios:
- Frequency Mode: Press the
VFO/MRbutton until the display shows a frequency (e.g., 145.000 MHz). - Channel Mode: Press the
VFO/MRbutton until the display shows a channel number (e.g., CH-01) or a programmed channel name (if named using software).

Practical Uses
- Frequency Mode: Ideal for initial setup, testing, and exploring new frequencies. For instance, if you’re trying to find a new repeater or want to monitor a specific frequency temporarily.
- Channel Mode: Best for regular operations and ease of use. For example, you can have local repeater frequencies, family communication channels, and emergency frequencies programmed for quick access.
Conclusion
Both modes have their specific uses and benefits.
Frequency Mode offers flexibility and on-the-fly adjustments, while Channel Mode provides convenience and organization for regular operations.
