Rotate the encoder knob to scroll through available bands (FM, AM, LW, MW, SW). Press the encoder knob to select the desired band. Tuning and Adjusting Step Size Rotate the encoder knob to scan frequencies manually. To change the tuning increments, press the button.
Understanding the hardware capabilities helps you maximize performance. SI4732 (highly integrated broadcast receiver chip) Frequencies Covered: FM: 64 – 108 MHz (supports RDS where applicable)
, and its successor the , are compact, high-performance all-band radio receivers designed for shortwave listeners (SWL) and radio hobbyists. Built around the powerful SI4732 DSP chip and driven by an Arduino-based
The device is prized for its versatility, supporting a wide range of broadcast and amateur bands: Frequency Range: ats-20 radio manual
By combining the information in this guide with additional resources and support, you'll be well on your way to becoming an expert ATS-20 radio operator and enjoying the many rewards of ham radio.
Issue 2: Audio cuts out or distorting heavily on strong signals
This is your primary tool. Rotate it to change frequencies or navigate menus. Press it to confirm a selection. Rotate the encoder knob to scroll through available
Shows current frequency, signal strength (RSSI), signal-to-noise ratio (SNR), step size, bandwidth, volume, and battery status.
Electronics like routers, LED bulbs, and PC monitors cause heavy RF noise. Move near a window.
The defining feature of the ATS-20 is its ability to decode Single Sideband (SSB) signals, which are widely used by ham radio operators, maritime traffic, and utility stations. Activating SSB Mode Switch to the band using the BAND button. To change the tuning increments, press the button
Features adjustable audio bandwidth filters (0.5, 1, 1.2, 2.2, 3, and 4 kHz) to help isolate weak signals.
