- DAHDIT.EXE
- A Code Practice Program
- Version 4.00, September 7, 1992
- By K. Scott Johnson
-
-
- WHAT THE HELL IS IT?
-
- DAHDIT is a very simple, very small, and very fast program for Morse
- code practice. There's nothing fancy about it, but it's designed for
- ease of use minimal complexity. The frequency of the audio tone and the
- sending speed are both adjustable.
-
-
- HOW DO I USE IT?
-
- To start DAHDIT, just type DAHDIT from the command line. The program
- will load, and you'll be shown a prompt like this one:
-
- [DAHDIT Version 4.00, compiled 09/17/1992]
- Copyright (C) 1992 by K. Scott Johnson.
-
- Enter your first name or callsign>
-
- The program wants your callsign for use in sending drills. Just
- enter it and press <ENTER>, which will take you to the main menu.
- The menu looks like this:
-
- [DAHDIT V4.00] Operator : KD4DCY Speed : 7.5 WPM
-
- Available Functions:
-
- <S> Change <S>peed.
- <F> Change tone <F>requency
- <R> Generate <R>andom code groups.
- <L> Generate code a <L>ine at a time.
- <C> Generate and show code a <C>haracter at a time.
- <G> Generate an automatic CQ message.
- <Q> <Q>uit.
-
- Most of the options are self-explanatory, but just to be safe, here's
- what each of them does.
-
- <S> changes the program's sending speed. The speed can be varied
- between 1 and 60 words per minute.
-
- <F> changes the frequency of the tone, with which DAHDIT sends its
- Morse characters. Any audio frequency can be specified, between
- 20 and 20,000 Hertz.
-
- <R> generates random five-character code groups for practice. You'll
- be asked how many groups you'd like sent, and sending will begin
- as soon as you press <ENTER>. As the code is sent, the character
- being sent will be displayed.
-
- <L> allows you to send a sentence, phrase, or other one-line text.
- You'll be prompted for the text, and sending will begin when you
- press <ENTER>.
-
- <C> allows you to generate and display visually individual Morse code
- characters. As you press a key, you hear the code and at the same
- time see the dots and dashes on the screen. This is useful for
- those who are still learning characters.
-
- <G> is really just for fun. It generates a complete CQ (general call
- to anyone) using your callsign.
-
- <Q> terminates the program.
