Morse Code Visualizer

Visual morse code decoder (not only) for the Raspberry Pi.

This a rewrite of morse using Gosu for Ruby.

Features

Screenshot

  • Decode morse code given either with keys on the keyboard or via an actual morse key attached at the serial port.
  • Encode text entered via keyboard.
  • Supports straight and iambic keyers (mode A and B).
  • Visualize pressed keys and generated sound for iambic keyers.
  • Morse code tree displaying the decoding process live.

Installation

  1. Install Ruby

     brew install ruby

  2. Install the SDL 2 library

     brew install sdl2

  3. Install Bundler

     gem install bundler

  4. Install required Ruby gems using bundler

     bundle install

Use the enter key to simulate a straight morse keyer. Use the left and right arrows to simulate a iambic keyer. Use the function keys to adjust the settings as indicated in the menu on the bottom.

Further Ideas

  • DXpedition simulation:
    1. Computer calls CQ or QRZ
    2. user answers with her call
    3. if user's input looks like a call: computer repeats user's call + 5NN
    4. user gives 5NN TU
    5. if user's input looks like report: user's call ends up in a log and computer calls CQ or QRZ (goto 1) else: computer repeats user's call + 5NN or calls CQ (goto 1)
