Description:
- This is a shortwave QRP SSB/CW transceiver. 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.
