HamGeek uSOTA-ATU USDX HF QRP SDR Transceiver Built-in ATU-100 Antenna Tuner

Description: Description HamGeek uSOTA-ATU USDX HF QRP SDR Transceiver Built-in ATU-100 Antenna Tuner with Dual OLED DisplayuSDX_ATU:1. uSDX: HF QRP SDR TransceiveruSDX is optimized and modified based on Guido PE1NNZ's open source project uSDX/QCX-SSB. uSDX is a shortwave QRP SSB/CW transceiver. With 1602 LCD screen and ultra-small size, it is easy to carry.Open source address: https://github.com/threeme3/QCX-SSBDiscussion group: https://groups.io/g/ucx/topics2. ATU: (Automatic Antenna Tuner Unit):Automatic Antenna Tuner Unit is a miniaturized clone of David Fainitski, N7DDC’s infamous 7X7 ATU100 automatic antenna tuner unit adapted for QRP operation up to 10 watts.uSDX_ATU Performance Characteristics:1. uSDX:- 8 bands: 3.5MHz; 5.3MHz; 7MHz; 10MHz; 14MHz; 18MHz; 21MHz; 29MHz- Emission efficiency: higher than 85% ( 3.5MHz; 5.3MHz; 7MHz; 10MHz; 14MHz); higher than 80% (18MHz and 21MHz); higher than 70% for 29MHz- Connect to PC, use FT8, JS8, FT4 and other digital mode software control, support CW automatic decoding- It can reach 3-5W power in 8 bands and can freely upgrade the PA module (TO-220)- High-precision TCXO for KDS, frequency accuracy better than 1PPM, frequency stability better than 0.5PPM- Independent core board, RF PA board and ATU board to avoid own signal interference- Ultra-small size: 100 x 90 x 57mm/3.9 x 3.5 x 2.2" (without protrusions)- All LPF parts use 100V C0G/NP0 capacitors- Use original LM4562 or LM833 or LT6231 op amp chip- Rich interfaces: HEADPHONE, PTT OUT, MIC/PTT, SPK/MIC- BNC antenna interface (with BCN-SL16 adapter, easy to match antenna)- External power supply: 12.6VDC (13.8VDC power adapter)2.
