Easily connect your antenna using the BNC connector, making this all mode HF transceiver versatile and user-friendly for both novice and experienced operators. This SDR QRP HF transceiver supports three frequency bands, providing flexibility and wide coverage for your communication needs, making it an essential tool for any radio enthusiast. Digital Power and SWR Display. Featuring a digital display for power and standing wave ratio (SWR), this all mode transceiver ensures precise monitoring and adjustment, enhancing your operating experience. FT8 Option Connector and Marking. The high frequency transceiver includes a connector for the FT8 option and marking for durability and clear labeling, making it a top choice for serious operators. USDX software open source. /> Some hardware open source websites. /> /> /> Group. This is a shortwave QRP SSB/CW transceiver. It has a 1602 screen, built-in microphone, built-in speaker! It can be connected to an autokey and can decode via CW. Simple, fun and versatile QRP SSB HF transceiver with embedded DSP and SDR capabilities. EER Class E drives the SSB transmit stage. 12V power supply provides about 5W maximum PEP SSB output. DSP filters: 4000, 2500, 1700, 500, 200, 100, 50Hz passband. 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. SSB reverse sideband/carrier suppression transmission: better than -45dBc, IMD3 (two-tone) -33dBc, reception: better than -50dBc. Supports multiple bands, continuously adjustable within the 160m-10m band (performance loss from 20kHz to 99MHz). 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. 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. Simple installation modification by replacing only 8 components and 8 wires. 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). 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). 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. Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB). Receiver Noise Level MDS: -135 dBm at 28MHz (200Hz BW). Receiver Front-End Selectivity: Steep Tuning Frequency -45dB/Decade Roll-off +/-2kHz. Blocking Dynamic Range: 123dB at 20kHz Offset, 78dB at 2kHz Offset. CW Decoder, Direct/Iambic-A/B Keyer. VFO A/B+RIT and Sp. CAT support (TS480 subset), you can stream audio, keystrokes and display text over CAT. This is probably the most cost-effective and easy to build standalone SDR/SSB transceiver. Greatly simplified the original QCX circuit i. 50% fewer mounting components, no complicated transformer windings, no alignment procedures, and more versatile. 100.00×80.00×40.00mm. Product Size: 3.94×3.15×1.57inch.
