Receiver

• Functional Description

  • Frequency Selection: Actual (sideband) vs "Window" (dialed in)
  • Does the communications plan list both?

• Modes of Operation

  • Continuous Wave (CW)
  • Frequency Shift Key (FSK)
  • Amplitude Modulation (AM)
  • Upper Side Band (USB)
  • Lower Side Band (LSB)
  • Independent Side Band (ISB)

Explain “window” (dialed in frequency) versus transmitted frequency (what is listed in communications plan). Subtract 1.5KHz from assigned frequency to get window frequency, which is dialed in.Communication plans often list window frequency in ( ).

Most common communications problem is wrong frequency used.
