It can also be decode CW coding. 3. IRF Launch Tube: With durable IRF series launch tube, can be used to connect antenna, which is on the instrument base. 4. Simple Structure: All aluminum buttons and translucent silicone buttons, the original transformer qcx circuit is greatly simplified, and the installation components are reduced by 50percent . No complicated windings. There is no wiring procedure. 5. High Efficiency: High power efficiency and simple design, thanks to eer electronic level transmitters, also very convenient to carry. Specification: 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 160m10m 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 RXTX switching, external PTT output with TXPA 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). 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 800kbits) 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 IQ (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. 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, IambicA, B keyer, VFO AB + 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 50percent , 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 to use 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 TS480. SPK: External speaker. .
