The correct answer is B: Store it in a memory channel. To enable quick access to a favorite frequency or channel, you store it in a memory channel. Most modern transceivers have memory channels where you can save frequencies along with their settings (offset, CTCSS tone, etc.) for quick recall. Memory channels allow you to quickly switch between your favorite frequencies without having to manually enter them each time. You program the frequency, offset, CTCSS tone, and other settings into a memory channel, then you can recall it instantly with a button press or channel selector. This is much faster than manually entering frequencies and is the standard way to manage multiple frequencies on modern transceivers.
