My homebrew HF transceiver RGO ONE consists of the following printed circuit boards:<\/p>\n

    \n
  1. Front Panel assembly – plastic front panel<\/strong><\/a>, control knobs<\/strong><\/a>, FSTN display<\/strong><\/a> and keyboards, control board<\/li>\n
  2. Mother board – fits all connectors on the rear panel, power supply, I\/O controller (second CPU) intended to be a chassis for all RF boards and options, as long as “cable harness” and board interconnections.<\/li>\n
  3. IF\/AF Board – IF and audio circuitry, IF AGC 134kHz. Second narrow band crystal filter (option). AF filter (option)<\/li>\n
  4. RF mixer board – RX\/TX switching, receiver front end, first RX mixer, TX mixer, first roofing crystal filter<\/strong><\/a>, ALC circuit. Noise blanker (option). SSB monitor amplifier.<\/li>\n
  5. Band pass filters – Front end filters 160-10m (160m option)<\/li>\n
  6. SSB GEN board – forms both CW and SSB signals, microphone amplifier, compressor unit (option, Line in\/Mic in circuit.<\/li>\n
  7. LO board – local oscillators, side tone and beep tone oscillator. First oscillator and BFO oscillator. SSB monitor .<\/li>\n
  8. Compressor unit (option)<\/li>\n
  9. Automatic antenna tuner (option).<\/li>\n
  10. Transverter\/RX antenna board (option).<\/li>\n
  11. Power amplifier assembly – consist of two boards PA55W<\/strong><\/a> and LPF<\/strong><\/a> nested directly onto the rear panel\n
