6. Morse Code

Software for use in conjunction with, or for facilitating Morse communication.

6.1 cw2hex

Author

G. Forrest Cook, WB0RIO, cook@stout.atd.ucar.edu

Description

cw2hex converts ascii text into Hex files for making keyer EPROMS.

Status

version 1.1 is tested and ready to go.

System requirements

standalone textual program, requires gcc to compile

Detail

This program takes a textual input and converts it to morse encoded characters in the form of a standard Intel HEX file. The Hex file can be used to program an EPROM which can then be connected to a simple circuit that generates canned messages. Possible uses are CW calling machines and CW beacon transmitter keyers. There is an accompanying schematic for a keyer circuit that works with this software.

Where and How to obtain it.

You can obtain cw2hex from www.atd.ucar.edu

6.2 SoundCard CW

Author

Steve Merrifield, VK3ESM, sjm@ee.latrobe.edu.au

Description

Morse Code practice for Linux, using a soundcard

Status

Completed

System requirements

Linux supported soundcard with FM support.

Detail

This program generates morse code characters using the soundcard. It does not rely on the Linux virtual console sound features and may therefore be used either with X11 or from a virtual console. Its features include:

Where and How to obtain it.

The software may be obtained from its home site at: livewire.ee.latrobe.edu.au.

Copyright/Licensing

6.3 GW4PTS Morse trainer.

Author

Alan Cox, GW4PTS, alan@lxorguk.ukuu.org.uk

Description

A Morse Code trainer that uses the PC internal speaker

Status

stable, works quite well, unfinished.

System requirements

Linux, any version

Detail

Alan wrote this small program in only an hour. It is quite neat, and allows you to play morse at a range of speeds and frequencies through the PC internal speaker. You can specify the text to be played either from the command line, from a file, or the program is capable of generating random character groups. As it stands you must invoke the program from a Linux Virtual Console, as it relies on certain kernel calls to produce the sound, and these don't work as easily from an XTerm. As it sounds each character it lists the character in verbal form (Di, Dit, Dah etc.) to the screen. Alan is hoping that someone will take the code and enhance it with the features he has listed in the comments at the head of the source file.

Where and How to obtain it.

I've had a large number of responses from people seeking this code, so I've obtained Alan's permission to make it available. You can obtain it from sunsite.unc.edu.
