It features a DSP filter with selectable bandwidths and DSP functions such as AGC, NR, VOX, and ATT, enhancing quality and user experience. Name: SDR Transceiver Material: metal Radio frequency output: 5W maximum PEP SSB output power at 12 V exit direct current in Frequency bands: 160m-10m Full mode support: usb, lsb, cw, am, frequency modulation 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, volumes control, dBm/S-meter. SSB reverse sideband/carrierwave suppression transmission: better than -45dBc, IMD3 (two tones) -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. SSB emitter 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). Noise floor MDS: -135 dBm at 28MHz (in 200Hz BW) Front-end selectivity: steep -45dB/decade roll-off +/-2kHz from tuned-frequency Blocking dynamic ranges: 20kHz offset 123dB, 2kHz offset 78dB CW decoder, Straight/Iambic-A/B keyer Package size: 60 * 60 * 50mm / 2.36 * 2.36 * 1.97in Package weight: 550g / 1.21lb
