: Short press the BWS or Band button to cycle through FM, AM, and various SW (Shortwave) bands.
: Rotate to change frequencies. Press the knob (on most firmware) to switch between tuning steps (e.g., 1kHz, 5kHz, 10kHz) or to enter specialized modes like ats-20 radio manual
Changes bandwidth filter settings (useful for reducing noise). Standard frequency navigation. Press to confirm or scan. Adjusts Beat Frequency Oscillator (BFO). 3. Advanced Operation Frequency Scanning : On firmware that supports it, ensure : Short press the BWS or Band button
Controls how "wide" the receiver listens. This is a DSP filter simulation. Standard frequency navigation
Updating the firmware (e.g., using ESPFlashDownloadTool ) can fix bugs or add "Pro" features like AIR band reception. im looking for ATS-20 Diagram
To change your tuning speed, press the button (or encoder). Common increments include: 1kHz / 5kHz: Best for AM/MW scanning. 100kHz: Fast scrolling through FM. 10Hz / 100Hz: Critical for "clarifying" voices in SSB mode. 5. Advanced Features
