Manual tuning and audio modes
Match the frequency, units and modulation to your signal.
In Manual mode, enter the frequency and select the displayed unit before tuning. A value in MHz is different from the same number in kHz. Confirm the resulting frequency in the receiver display.
Use WFM for compatible wideband FM broadcast, NFM for compatible narrowband FM, or AM for compatible amplitude-modulated audio. A visible carrier does not mean every mode will produce intelligible audio.
The supported tuner covers roughly 24–1766 MHz with a suitable antenna. The 2.4 GHz Wi-Fi/Bluetooth bands are outside that range. HF below about 24 MHz needs other appropriate hardware and a supported workflow.
Presets are convenient tuning ranges, not permission to monitor a service. Save a station only after checking its frequency and mode. The app does not decrypt encrypted communications.
