How do you adjust vhf and uhf radio frequency?

To adjust VHF (Very High Frequency) and UHF (Ultra High Frequency) radio frequencies, you typically use a tuning knob or digital interface on the radio device to select the desired frequency. Most radiOS have a frequency display that shows the current setting, allowing for precise adjustments. Additionally, some radiOS may have presets for commonly used frequencies, making it easier to switch between them. Always ensure that you are operating within the legal frequency ranges and regulations for your region.
