Ats-20 Radio Manual File

Forget the tiny pamphlet. Print this quick reference and tape it to the back of your ATS-20:

POWER ON: Long-press VF
SELECT MODE: Long-press Filter (AM > LSB > USB)
SAVE MEMORY: VFO mode > Long-press VM > Long-press VF
RECALL MEMORY: Short-press VM > Rotate Encoder
SSB TUNING: 10 Hz steps (press encoder to change step speed)
RESET DEVICE: Pinhole reset button next to USB port (paperclip)
HIDDEN MENU: Power off > Hold VOL + Power

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Won’t turn on | Dead battery / reversed polarity | Charge 4+ hrs; check 18650 orientation | | No FM reception | Antenna not connected (for SMA version) | Attach stub antenna or wire | | Poor shortwave | No external antenna | Add 15–30 ft wire outdoors | | Display flickers | Low battery or USB noise | Charge battery; use battery power | | Menus stuck | Accidental long press | Short press B or cycle power |

The original manual fails to explain how to save a frequency without overwriting another.

To save a frequency to memory:

Recall a memory: Short press BAND/VM to toggle between VFO and Memory modes. Then use the encoder to scroll through your saved channels.

To enter the Setup Menu, press and hold the Encoder Button (or sometimes a dedicated "Menu" button depending on firmware) for 2 seconds.

While the factory ATS-20 radio manual may leave you frustrated, this guide provides everything you need to enjoy one of the most fun, portable shortwave and SSB receivers on the market. The ATS-20 is not perfect—the UI has a learning curve, and the stock firmware has quirks—but with these instructions, you can unlock its full potential as a travel-friendly ham radio companion, an aviation band scanner, or a bedside world receiver.

Remember: The best accessory for your ATS-20 is patience. Spend an afternoon with the encoder and these notes, and soon you will be tuning in to transatlantic hams, marine weather faxes, and distant AM broadcasters like a pro.

ATS-20 Si4732 Radio Receiver: The Ultimate User Guide The ATS-20 (Si4732) has become a favorite among radio enthusiasts for its portability and impressive range. Whether you are a seasoned "ham" or a newcomer to shortwave listening, this guide serves as your comprehensive ATS-20 radio manual to help you master its features. 1. Getting Started

Before diving into the frequencies, ensure your device is ready:

Charging: Most units use a Mini-USB or USB-C port. A red LED usually indicates charging, turning off or green when the 3.7V lithium battery is full.

Antenna: Screw the telescopic antenna into the BNC connector. For better HF (High Frequency) reception, consider using an external long-wire antenna. 2. Controls and Layout Forget the tiny pamphlet

Encoder Knob: This is your primary tool. Rotate it to change frequencies or navigate menus. Press it to confirm a selection.

Power Switch: Usually located on the side or back to toggle the unit on/off.

Volume: Adjust using the dedicated knob or through the digital interface (depending on your specific firmware version). 3. Selecting Modes and Bands

The ATS-20 covers a massive range including FM, AM, and SSB. Use the Bands menu to cycle through: FM: Standard broadcast radio (64–108MHz). MW (Medium Wave): Standard AM radio. SW (Shortwave): 1.7MHz to 30MHz.

LSB/USB (Lower/Upper Sideband): Essential for listening to amateur radio operators on HF bands. 4. Tuning and Steps

To change your tuning speed, press the Step 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

Bandwidth (BW): You can adjust the filter width to cut out interference. Use narrower settings (e.g., 2.0kHz) for crowded SSB bands and wider settings (e.g., 6.0kHz) for high-quality AM.

BFO (Beat Frequency Oscillator): When in SSB mode, the BFO allows you to fine-tune the pitch of the voice to make it intelligible. Rotate the encoder until the "Donald Duck" sound turns into a clear human voice. 6. Menu Settings

By accessing the internal menu (usually a long press of the encoder), you can: Adjust Brightness: Save battery by dimming the OLED screen. Scan: Automatically search for the next strongest station. Mute: Quickly silence the audio. Troubleshooting Tips

No Sound on SW? Check your gain settings and ensure you are outside or away from electronic interference like LED bulbs or PC power supplies. | Problem | Likely Cause | Solution |

Firmware Updates: Many ATS-20 radios run on Arduino-based code. If your device feels "buggy," the enthusiast community often releases updated sketches that improve stability and add features.

Note: Always remember that radio propagation changes with the time of day. Lower frequencies (3–10MHz) usually work better at night, while higher frequencies (15–30MHz) are better during the day.
