Specification: Item Type: SDR Transceiver Material: Aluminium Alloy Battery: 1 x 3500mAh lithium battery 605585, delivery with built in battery. Function: Transceiver: A QRP SSB HF transceiver with embedded DSP and SDR functions. : EER E driven SSB stage. Output: 13.8V power supply provides about 10W PEP SSB output. Full Mode Support: USB, LSB, CW, AM, DSP Filter: 4000, 2500, 1700, 500, 200, 100, 50Hz passband. DSP Function: Automatic gain control AGC, noise reduction NR, voice , voice Xmit , 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 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 , 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 . PA key shaping circuit. Fully Digital and Software Based SDR Receiver Stage optional: Sample the I/Q complex from the quadrature sampling detector digital mixer, and perform a 90 degree phase 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 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: : Charging port of the built in lithium battery and can only use the supplied . It is forbidden to use other 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 , PTT . MIC: External microphone port. UART: Serial port, command compatible with TS-480. SPK: External speaker. Package List: 1 x SDR Transceiver1 x Mic 1 x 1 x 3 in 1 Screwdriver
