It has a 1602 screen, built-in microphone, built-in speaker! It can be connected to an autokey and can decode via CW<br /> <br /> Feature list:<br /> Simple, fun and versatile QRP SSB HF transceiver with embedded DSP and SDR capabilities.<br /> EER Class E drives the SSB transmit stage.<br /> 12V power supply provides about 5W maximum PEP SSB output.<br /> Full mode support: USB, LSB, CW, AM, FM.<br /> DSP filters: 4000, 2500, 1700, 500, 200, 100, 50Hz passband.<br /> DSP functions: 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.<br /> SSB reverse sideband/carrier suppression transmission: better than -45dBc, IMD3 (two-tone) -33dBc, reception: better than -50dBc.<br /> Supports multiple bands, continuously adjustable within the 160m-10m band (performance loss from 20kHz to 99MHz).<br /> Open source firmware, built-in Arduino IDE; allows experimentation, new features can be added, contributions can be shared through Github, software complexity: 2000 lines of code.<br /> Software-based VOX can be used as fast full-intrusive (QSK and semi-QSK operation), or auxiliary to operate in digital mode (no CAT or PTT interface) for RX/TX switching, external PTT output with TX/PA control delay.<br /> Simple installation modification by replacing only 8 components and 8 wires.<br /> &nbsp;Lightweight, low-cost transceiver: thanks to the EER transmitter E-level, it has high power efficiency (no bulky heat sink required) and simple design (no complex balanced linear power amplifier required).<br /> SSB transmitter stage is completely digital and software-based: samples the microphone input and reconstructs the SSB signal by controlling the phase of the SI5351 PLL (via I2C with small frequency changes above 800kbit/s) and the amplitude of the PA (via PWM of the PA key shaping circuit).<br /> Fully digital and software-based SDR receiver stage (optional): samples the I/Q (complex) signal from the quadrature sampling detector digital mixer and performs a 90 degree phase shift (Hilber transform) in software and eliminates one phase shift by adding a sideband.<br /> Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB).<br /> Receiver Noise Level MDS: -135 dBm at 28MHz (200Hz BW).<br /> Receiver Front-End Selectivity: Steep Tuning Frequency -45dB/Decade Roll-off +/-2kHz.<br /> Blocking Dynamic Range: 123dB at 20kHz Offset, 78dB at 2kHz Offset.<br /> CW Decoder, Direct/Iambic-A/B Keyer.<br /> VFO A/B+RIT and Sp<br /> CAT support (TS480 subset), you can stream audio, keystrokes and display text over CAT.<br /> This is probably the most cost-effective and easy to build standalone SDR/SSB transceiver. Greatly simplified the original QCX circuit (i.e., 50% fewer mounting components, no complicated transformer windings, no alignment procedures), and more versatile.<br /> Shell Material: ABS<br /> Product Size: Approx. 100.00x80.00x40.00mm<br /> Product Size: 3.94x3.15x1.57inch<br /> </p> <p> <strong>Note:</strong><br /> Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
