It boasts 1602 screen, 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 (BNC connector) - 3 bands. Power standing wave digital display! - Dimensions: 80 x 40 x 100mm - Provide ft8 option connector later - Aluminum shell laser marking Function List: - Simple, interesting and versatile QRP SSB HF transceiver with embedded DSP and SDR functions. - EER E-level driven SSB launch stage. - 12V power supply provides about 5W Max 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 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 to 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 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.
