Features: This QRP SSB transceivers with embedded DSP and SDR functions and E-level driven SSB launches stage. Full mode support: USB, LSB, CW, AM, FM, and it can be connected to an automatic key, and can be decoded by CW. DSP filter: 4000, 2500, 1700, 500, 200, 100 and 50Hz passband and DSP with powerful functions such as automatic gain control (AGC), noise reduction (NR), voice trigger, voice trigger Xmit (VOX), RX attenuator (ATT), TX noise gate, TX driver control, volumes control, dBm/S-meter. SSB reverse sideband/carrier 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..99MHz). SSB transmitters 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 signal. PA keys shaping circuit). C-AT support (TS480 subset), you can stream o, press keys, and display text through C-AT.
