Ats-20 - Radio Manual

He followed the instructions. He spun the dial backward. 150 kHz. 100 kHz. 50 kHz. The static deepened into a low, rhythmic thrum. It wasn't a station. It sounded like a heartbeat, slow and planetary. He felt a strange vertigo, as if the concrete floor beneath him was rotating.

For , fully extend the antenna. Experiment with tilting it at a 45-degree angle to change its polarization relative to the incoming signal. Connecting External Antennas

: Enables or disables Automatic Volume Control specifically for Single Side Band.

In SSB (USB/LSB) mode, press the TUNE/BFO button once to enter BFO mode for fine-tuning voice signals. ats-20 radio manual

The stock telescopic antenna is generally weak indoors. For optimal performance, connect an external wire antenna (like a random wire antenna or a magnetic loop antenna) to the BNC port. Even stringing 20-30 feet of speaker wire out of a window will dramatically increase the number of signals you hear.

The ATS-20 (and its updated sibling, the ATS-20+) is built around the chip, controlled by an Arduino Nano or Uno compatible microcontroller. Frequency Range: FM: 76–108 MHz. AM/MW: 520–1720 kHz. LW: 150–510 kHz.

OLED Display Screen, Main Rotary Encoder Knob (with press-button function), and four physical tactile buttons ( BW, MODE, BAND, STEP ). He followed the instructions

SSB is crucial for listening to amateur radio operators (hams), maritime communications, and aviation weather broadcasts.

The OLED display draws notable power. Enter the menu ( B1 ) and enable an automatic screen timeout if your firmware version supports it. Firmware Flashing

Select Arduino Uno or Nano (matching your hardware). Program: Choose the firmware file and flash the device. 100 kHz

She frantically pressed buttons. The ATS-20 screen showed “AGC” and “ATT” and “BW” but she had no idea what they meant. Her phone was dead. No YouTube tutorials. No forums. Just her, the static, and the radio.

Spin the Tuning Encoder until you locate a station. Adjust the volume using the analog wheel. 🛠️ Advanced Operations: Tuning SSB
