1. Introduction
The DeepSDR 101 is a sophisticated DSP digital demodulation radio built upon a Software Defined Radio (SDR) architecture. It offers a wide 192kHz spectrogram and waterfall display, coupled with 16-bit sampling, to deliver a high-dynamic-range receiver. This device supports multiple demodulation functions including CW, AM, SSB, and FM.
Constructed with an all-aluminum alloy CNC shell, the SDR-101 features a vibrant 4.3-inch IPS LCD screen with an 800x480 resolution, all within a compact and portable design. It is designed for enthusiasts to enjoy radio listening anywhere, anytime.

- Initial Screen Interaction: The device features a resistive touch screen. Use the provided double-head touch pen for precise interaction with the display.
5. Operating Instructions
The SDR-101 offers various modes and features for radio reception.
5.1 Basic Navigation
- Rotary Encoder: Turn the knob to adjust frequency, navigate menus, or change settings. Press the knob to confirm selections or access sub-menus.
- Touch Screen: Use the touch pen to interact directly with on-screen elements, such as frequency input, mode selection, and display options.
5.2 Mode Selection
The SDR-101 supports the following working modes:
- CW (Continuous Wave)
- AM (Amplitude Modulation)
- LSB (Lower Sideband)
- USB (Upper Sideband)
- WFM (Wideband Frequency Modulation)
Select the desired mode via the touch screen interface or rotary encoder menu.
5.3 Frequency Tuning
Tune to your desired frequency using the rotary encoder. The minimum tuning step is 1Hz. You can also directly input frequencies via the touch screen.
5.4 Spectrogram and Waterfall Display
The 192kHz wide spectrogram and waterfall display provide a visual representation of the radio spectrum, allowing you to identify signals and interference. Observe the patterns and colors to understand signal strength and activity across different frequencies.
6. Maintenance
6.1 Cleaning
- Wipe the device with a soft, dry cloth.
- For stubborn marks, slightly dampen the cloth with water. Do not use harsh chemicals or abrasive cleaners.
- Keep the screen clean using a microfiber cloth to avoid scratches and maintain clarity.
6.2 Battery Care
- To prolong battery life, avoid fully discharging the battery frequently.
- Store the device in a cool, dry place when not in use for extended periods.
7. Troubleshooting
7.1 Charging Status Indicators
The device uses RED and Blue LEDs to indicate charging and battery status:
| Status | RED LED | Blue LED |
|---|---|---|
| Charge: charging | Blink | OFF |
| Charge: full | ON | OFF |
| Discharge: discharging | OFF | ON |
| Discharge: low battery | OFF | Blink |

7.2 Common Issues
- Device does not power on: Ensure the battery is charged. Connect the device to a power source and check the charging indicator.
- No signal reception: Verify the antenna is properly connected. Check the selected frequency and demodulation mode. Ensure you are within a reception area for the chosen frequency band.
- Screen unresponsive: Use the provided touch pen for interaction. If still unresponsive, try restarting the device.
