SDR Transceiver HF QRP 8 Band SSB CW Shortwave Radio Receiver Transmitter for DIY US Plug 110‑240V Item Type: SDR Transceiver Material: Aluminium Alloy Battery: 1 x 3500mAh lithium battery 605585, delivery with built in battery. Function: Radio Transceiver: A QRP SSB HF transceiver with embedded DSP and SDR functions. Launch: EER E level driven SSB launch stage. Output: 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 attenuator (ATT), TX noise gate, TX driver control, volume control, dBm S meter SSB Reverse Sideband and Carrier Suppression Transmission: Better than -45dBc Two Tones IMD3: -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 IDE: Allows experimentation, can add new functions, can share contributions through Github, software complexity: 2000 lines of code. Features: 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 Installation: Simple installation modification with 8 component changes and 8 wires. High Efficiency: 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). 3 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 Supporting CAT with TS480 Subset: You can stream audio, press keys, and display text through CAT. SDR SSB transceiver: Great simplification simplifies the original QCX circuit, that is, reducing the installation components by 50%, does not require complex transformer windings, and does not require alignment procedures. Port Introduction: Charge: Charging port of the built in lithium battery and can only use the supplied charger. It is forbidden e other chargers Switch: OFF to shut down. BAT: Built in battery power supply. 13.8: External power supply DC 13.8V 3A: External power supply port KEY: Automatic key body connection, A, B, single key. PA: External power amplifier, PTT signal. MIC: External microphone port. UART: Serial communication port, command compatible with TS-480. SPK: External speaker.
