USDX/QCX-SSB GitHub:


Description:
This is a shortwave QRP SSB/CW transceiver. Ultra-small size makes it easy to carry for outdoor use. It boasts a built-in 4000mAh lithium battery, a 1602N LCD screen, a built-in speaker. It supports connection to a PC and uses FT8, JS8, FT4 and other digital mode software control, and supports CW automatic decoding.

Features:

  • 8 bands cover 80m/60m/40m/30m/20m/17m/15m/10m
  • Excellent PCB layout design in line with high-frequency circuit design principles to ensure excellent performance
  • Whether using internal battery or external 13.8v power supply, it can reach 3-5W power in 8 bands, and reserve the SOT-223 and TO-220 package pads required for upgrading
  • High emission efficiency, 80m/60m/40m/30m/20m efficiency is higher than 80%, 17m efficiency is higher than 70%, 15m/10m efficiency is higher than 60%
  • High-precision KDS brand TCXO, frequency accuracy is better than 1PPM, frequency stability is better than 0.5PPM
  • Ultra-small size: 83*38*124mm (excluding protruding parts)
  • Abundant interfaces (CAT, PTT OUT, MIC/KEY, K-head microphone)
  • All LPF parts use 100V C0G/NP0 capacitors
  • Use original genuine Omron magnetic latching relays
  • Use op amp chip with lower noise than LM4562
  • Built-in speaker with cavity
  • Built-in 11.1v (12.6v) lithium battery
  • BNC antenna interface

List of Functions:

  • Simple, fun and versatile QRP SSB HF transceiver with embedded DSP and SDR functions;
  • EER Class-E driven SSB transmit-stage
  • Approximately 5W PEP SSB output from 13.8V supply
  • All-Mode support: USB, LSB, CW, AM, FM
  • DSP filters: 4000, 2500, 1700, 500, 200, 100, 50 Hz passband
  • DSP features: Automatic Gain Control (AGC), Noise-reduction (NR), Voice-triggered Xmit (VOX), RX Attenuators (ATT), TX noise gate, TX drive control, Volume control, dBm/S-meter
  • SSB opposite side-band/carrier suppression Transmit: better than -45dBc, IMD3 (two-tone) -33dBc, Receive: better than -50dBc
  • Multiband support, continuously tunable through bands 160m-10m (and from 20kHz..99MHz with loss in performance)
  • Open source firmware, built with Arduino IDE; allows experimentation, new features can be added, contributions can be shared via Github, software-complexity: 2000 lines of code
  • Software-based VOX that can be used as fast Full Break-In (QSK and semi-QSK operation) or assist in RX/TX switching for operating digital modes (no CAT or PTT interface required), external PTT output/PA control with TX-delay
  • Simple to install modification with 8 component changes and 8 wires
  • Lightweight and low-cost transceiver design: because of the EER-transmitter class-E stage it is highly power-efficient (no bulky heatsinks required), and has a simple design (no complex balanced linear power amplifier required)
  • Fully digital and software-based SSB transmit-stage: samples microphone-input and reconstruct a SSB-signal by controlling the phase of the SI5351 PLL (through tiny frequency changes over 800kbits/s I2C) and the amplitude of the PA (through PWM of the PA key-shaping circuit)
  • Fully digital and software-based SDR receiver-stages (optionally): samples I/Q (complex) signal from Quadrature
  • Sampling Detector digital mixer, and performs a 90-degree phase-shift mathematically in software (Hilbert-transform) and cancels out one side-band by adding them
  • Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB)
  • Receiver Noise floor MDS: -135 dBm at 28MHz (in 200Hz BW)
  • Receiver Front-end selectivity: steep -45dB/decade roll-off +/-2kHz from tuned-frequency
  • Blocking dynamic range: 20kHz offset 123dB, 2kHz offset 78dB
  • CW decoder, Straight/Iambic-A/B keyer
  • VFO A/B + RIT and Split, and corresponding relay band-filter switching via I2C  CAT support (TS480 subset)

Specifications:

  • Type: HF QRP SDR Transceiver
  • Mode: SSB/CW
  • Rf output: 10W max at 13.8V exit DC in
  • Frequency range: 3.5-30MHz
  • Built-in MIC
  • Antenna/connector: 50ohms/SO-239

Software

Hardware 1

Hardware 2

 

 


It is optimized from uSDX QCX-SSB open source hardware. The powerful software supports the use of less hardware to complete the SW transceiver and supports the SSB mode (reception quality is very good, transmission quality is slightly worse). In addition, the developer also developed an AM/FM mode for it, but AM/FM is defined as a gift function. Don't expect AM/FM too high.

Support 8 frequency bands:

  • 80-meter band (3.5MHz);
  • 60-meter band (5.3MHz);
  • 40-meter band (7MHz);
  • 30-meter band (10MHz);
  • 20-meter band (14MHz);
  • 17-meter band (18MHz);
  • 15-meter band (21MHz);
  • 10m band (29MHz);
