Ats-20 Radio Manual Jun 2026

Troubleshooting and Diagnostics A practical troubleshooting section pairs symptoms (no power, low output, receive noise) with likely causes and stepwise checks (verify power voltage, fuses, wiring, antenna SWR). Inclusion of typical test points and expected voltages/currents accelerates diagnostics. Flowcharts and decision trees make troubleshooting more accessible.

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.

Displays the current frequency, signal strength (RSSI/SNR), current step size, battery indicator, and active mode (AM/FM/SSB).

Spin to change frequencies. Press it inward to toggle secondary functions like the BFO (Beat Frequency Oscillator) fine-tuning layer. 🚀 Quick-Start Guide Get up and running in under 60 seconds with these steps:

Use a small Phillips screwdriver. Do not strip the tiny screws. Step 2 – Battery orientation: Insert an unprotected flat-top 18650 lithium-ion battery. Positive (+) terminal goes towards the top of the radio (near the SMA antenna connector). Negative goes towards the bottom. Step 3 – Power on: Long press the Power/VF button for 1.5 seconds. If the screen flashes and dies, your battery is low or inserted backward. Step 4 – Antenna: The SMA connector is fragile. Do not over-tighten. For SW/HF, a 5-7 meter long wire is best. For FM, use the included telescopic whip.

Press the button to cycle from AM to USB (Upper Sideband) or LSB (Lower Sideband). 100 kHz

Understanding the hardware limits helps you choose the right external antennas and operations:

Ensure you are using a dedicated 5V/1A charging brick rather than a high-wattage laptop or smartphone fast charger, which can trip the simple internal charging protection circuit. If the cell is completely dead, the chassis can be unscrewed to replace the internal 3.7V 18650 lithium cell. 6. Advanced Tips: Firmware Modification

Issue 4: The rotary encoder skips frequencies or behaves erratically.

Press and hold the POWER button until the OLED screen lights up.
