USDX USDR HF QRP SDR Transceiver SSB/CW Transceiver 8-Band 5W DSP SDR Black Shell w/ Handheld Mic

Description:
This is a shortwave QRP SSB/CW transceiver. It boasts 1602 screen, built-in battery, equipped with charger, built-in mic, built-in speaker! It can be connected to an automatic key, and can be decoded by cw.

Features:
– Using IRF series launch tube, durable
– Can be used by connecting the antenna (M seat)
– 8 bands. Power standing wave digital display! External 13.8v maximum power 10w! Built-in 12.6v battery
– Dimensions: 76 x 46 x130mm/3 x 1.8 x 5.1″
– Provide ft8 option connector later
– Use TCXO for KDS. Accuracy 0.5PPM (1PPM per year)
– Aluminum shell laser marking
– All-aluminum knobs! Translucent silica gel button (receive green, emit red)

Function List:
– Simple, interesting and versatile QRP SSB HF transceiver with embedded DSP and SDR functions
– EER E-level driven SSB launch stage
– 13.8V power supply provides about 10W PEP SSB output
– Full mode support: USB, LSB, CW, AM, FM
– 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 (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..99MHz)
– Open source firmware, built in for Arduino IDE; allows experimentation, can add new functions, can 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, 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 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
– CW decoder, straight/Iambic-A/B keyer
– VFO A/B + RIT and Split, and switch the corresponding relay band filter through I2C
– 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
