Description: uSDX V2+ PLUS QCX-SSB 3-5W 8 Band SDR All Mode HF SSB QRP Transceiver + Battery USDX/QCX-SSB GitHub: https://github.com/threeme3/QCX-SSB/tree/feature-rx-improved Descriptions: 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: Frequency range 3.5-30MHz 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 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) Packages Included: 1 x Host USDX+ 1 x Mic 1 x Charger
