Drop the bandwidth down to 2.2 kHz or 3.0 kHz . This cuts adjacent channel interference and drops the noise floor.
What are you most interested in catching (local FM, international shortwave, or ham operators)?
Changes the tuning increment step (e.g., 1kHz, 5kHz, 9kHz, 10kHz, 100kHz). Look for the underline cursor on the OLED screen to see which digit will change when you turn the encoder.
If you get stuck, do not search for an official PDF. Instead, go to the source of the "Better Manual":
This knob changes frequencies, navigates menus, and selects options. It also clicks inward (acts as a button) to switch tuning steps.
