4 Bands uSDX USDR Pocket Radio Handheld 10/15/20/40M 3 Band HF SSB QRP Transceiver Compatible with uSDX QCX-SSB

Introduction: This is a HF band QRP SSB / CW transceiver. It is very small and easy to carry outdoors. It uses a 1.3 "OLED LCD screen for easy reading. Built in speaker, support to connect to PC, use FT8, jt65, FT4 and other digital modes, support CW mode, software control, and support CW automatic decoding. Characteristic: 1. 4-band coverage 10/15/20/40M 4 Band (modified based on the source program and different from the source program).

2. Excellent PCB design and excellent circuit performance.

3. Need 12.6V power supply, the power can be up to 3-5w in forth bands.

4. High launch efficiency, with 40m / 20m efficiency higher than 80% and 15m efficiency higher than 60%. (Note: transmission is prohibited in non 40m / 20m / 15m / 10m band and can only be used for reception).

5. Ultra small volume and weight: 82 * 50 * 20MM (excluding protruding parts), body weight 180g, very suitable for mountaineering.

6. Multiple interface - CAT(Firmware Upgrade port), MIC / key, audio (headset supporting Android adaptation).

7. 100V or 250V cog / NPO capacitors are used for LPF.

8. Use Omron magnetic holding relay, TCXO Crystal oscillator

9. Use ne5532 operational amplifier chip.

10. Built in high-quality speakers, BNC antenna interface. Specification: - Frequency Range: Receiving: 0.5MHz ~ 30MHz (theoretically it can reach the limit of SI5351) Transmission: 1.8～30MHz(limited by LPF) - Working mode: CW, AM, SSB - Minimum step: 10Hz - Antenna Impedance: 50Ω - Operating temperature range: 0℃～+50℃ - Power supply voltage: 10.5 ~ 12.6V DC, the negative pole is grounded. - Current consumption: Receive: 100mA@Max Launch: 1A@Max - Body size: 50 x 20 x 80mm (W x H x L) (excluding protrusions) - Weight: about 180g (main unit only) - RF output power: 0.1-5W (SSB/CW) 0.1-5W(AM carrier) @12.6VDC - Battery capacity: 1100mah - Power interface: DC5521 Note: 1. This machine is optimized and modified according to the open source settings, and its performance and functions are fully compatible with the original design. More updated functions are subject to the actual use of the firmware version. If you have the skills, you can optimize it, and it is recommended to post your hardware and software update records in the open discussion group. For more information, please refer to the relevant open source files of the original project. 2. Battery not included, please prepare a suitable power supply by yourself to use it, The voltage of the power supply must not exceed 12.6V Package includes: 1 set of Pocket Radio
