  • frequency in Hz.
  • gain
  • filter setting
  • mode (AM/SSB)
  • Passband shift
  • BFO
  • frequency calibration
  • AGC
  • Mute
  • scan-mode
  • memory presets
  • data rate (speed limit)
  • time clock
  • memory preset selection
  • 5 modulator units
  • indicators that show which radio parameters are getting modulated
  • and others…
