Description: Description 5W usDX SDR QRP HF Transceiver All Mode Transceiver Supporting 15M 20M 40M Bands + Black Morse Key USDX Software Open Source: https://github.com/threeme3/QCX-SSB/tree/feature-rx-improved Some Hardware Open Source Sites: https://dl2man.de/ https://antrak.org.tr/blog/projeler/usdx-an-arduino-based-sdr-all-mode-hf-transceiver-pcb-iteration-v1-02/ https://www.qsl.net/py2ohh/trx/usdx/usdx.html Group: https://groups.io/g/ucx/topics Description: This is a QRP SSB/CW HF transceiver. It boasts a 1602 screen, a built-in mic and a built-in speaker! It can be connected to an automatic key, and can be decoded by CW. Features: - It is durable, using IRF series MOSFET - Can be used by connecting an antenna (BNC connector) - 3 bands. With power standing wave digital display - Dimensions: 80mm x 40mm x 100mm/3.1" x 1.6" x 3.9" - Provides FT8 option connector later - Aluminum shell with laser marking Function List: - Simple, interesting and versatile QRP SSB HF transceiver with embedded DSP and SDR functions - EER class-E driven SSB transceiver - 12V power supply provides about 5W maximum PEP SSB output - All mode transceiver: supports USB, LSB, CW, AM and FM - DSP filter: 4000, 2500, 1700, 500, 200, 100, 50Hz pass-band - DSP function: automatic gain control (AGC), noise reduction (NR), voice trigger, voice trigger Xmit (VOX), RX attenuator attenuator (ATT), TX noise gate, TX driver control, volume control, dBm/S-meter - SSB reverse side-band/carrier suppression transmission: better than -45dBc, IMD3 (two tones) -33dBc, reception: better than -50dBc - Supports multiple bands. Continuously adjustable in the 160m-10m frequency band (and performance loss from 20kHz to 99MHz) - Open source firmware, built in for Ar-duino IDE; allows experimentation. You can add new functions and share contributions through Github. Software complexity: 2000 lines of code - Software-based VOX can be used as a fast full invasive (QSK and semi-QSK operation), or to assist in running in digital mode (without CAT or PTT interface) for RX/TX switching and external PTT output with TX/PA control-delay - Simple installation modification with 8 component changes and 8 wires - Lightweight, low-cost transceiver: Thanks to EER transmitter E-level, it has high power efficiency (no bulky heat sink required), and simple design (no need for complex balanced linear power amplifiers) - SSB transmitter stage based entirely on software: By controlling the phase of the SI5351 PLL (via the tiny frequency change of I2C over 800kbit/s) and the amplitude of the PA (via the PWM of PWM) to sample the microphone input and reconstruct the SSB signal. PA key shaping circuit) - Fully digital and software-based SDR receiver stage (optional): sample the I/Q (complex) signal from the quadrature sampling detector digital mixer, and perform a 90-degree phase shift in the software (Hilber transform) and eliminate one by adding side-bands - Independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB and -73dB) - Receiver noise level MDS: -135 dBm (200Hz BW) at 28MHz - Receiver front-end selectivity: steep tuning frequency -45dB / ten times roll-off +/- 2kHz - Blocking dynamic range: 20kHz offset 123dB; 2kHz offset 78dB - CW decoder and straight/Iambic-A/B keyer - VFO A/B + RIT and and Split, and switch the corresponding relay band filter through I2C - Supports CAT (TS480 subset). You can stream audio, press keys, and display text through CAT - This is probably the most cost-effective transceiver and easy to build standalone SDR/SSB transceiver. - Great simplification: It simplifies the original QCX circuit (that is, reduces the installation components by 50% and it does not require complex transformer windings nor require alignment procedures), and it is more versatile Package Included: - 1 x Transceiver - 1 x Hand microphone - 1 x Audio cable - 1 x Morse key Packaging Details: - G.W.: 0.55kg Note: - Please fix the Morse key before using because it is 3D printed and light in weight.
