USDX QCX-SSB To SSB Transceiver QRP SDR Transceiver 8-Band DSP SDR Function. USDX software open source. This is a shortwave QRP SSB/CW transceiver. It boasts 1602 screen, equipped with charger, built-in speaker! Be connected to an automatic key, and can be decoded by cw. Using BS170 series tranismit tube, durable. Can be used by connecting the antenna (BNC socket). Power standing wave digital display! External 13.8v maximum power 10w! Dimensions: 76 x 37 x100mm. Use TCXO for KDS. Accuracy 0.5PPM (1PPM per year). Simple, interesting and versatile QRP SSB transceiver with embedded DSP and SDR functions. EER E-level driven SSB launch stage. 13.8V power supply provides about 5W PEP SSB output. DSP filter: 4000, 2500, 1700, 500, 200, 100, 50Hz passband. 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 sideband/carrier suppression transmission: better than -45dBc, IMD3 (two tones) -33dBc, reception: better than -50dBc. Multi-band support, continuously adjustable in the 160m-10m frequency band and performance loss from 20kHz.. 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 digital and 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 sidebands. Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -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. CAT support (TS480 subset), you can stream audio, press keys, and display text through CAT. This is probably the most cost-effective and easy to build standalone SDR/SSB transceiver. Great simplification Simplifies the original QCX circuit (that is, reduces the installation components by 50%, reduces the installation components by 50%, does not require complex transformer windings, and does not require alignment procedures), and is more versatile. DC 5.5-2.1 , max 15v, 13.8V/3A: External power supply port. KEY: automatic key body connection (A, B, single key). PA: External power amplifier, PTT signal. MIC: External microphone port. SPK: External speaker. 1 x Set of Transceiver. 1 x Hand-held MIC. Usually it cost about 35USD-50USD. Thanks for your understanding.
