Amateur Radio Software

1 IntroductionI'm also a licensed radio amateur - M0CUV's the callsign. Here's some software for Linux that may be useful for practicing morse... (it's no substitute for listening to a real amateur though).
2 MorseGreat name for a package, that ;-) It's like Clint Eastwood calling his Horse "Horse".
Download it here. It's a Morse training package for Linux, with the following features:
"morse" - Morse Training Software for Linux ------------------------------------------- (C) 2000 Matt J. Gumbley, G7JFJ This package contains several programs and Perl scripts which might help you to learn Morse code. I wrote this code to help me through the RSGB's 12 WPM Morse test, after a conversation with my instructor at Maidstone Amateur Radio Society, Colin Wilson. Colin's training in the services amounted to "brainwashing" - a letter would flash up on a screen with the appropriate Morse character being sent - at high speed. One problem I have when reading Morse is that I occasionally stumble over a character, and by the time I've worked it out, I've missed the rest of the word. The translation has to be automatic; unconscious. To this end, I wrote these tools.... PREREQUISITES ------------- You need a working sound card. I can't go into this in any depth here - you must have /dev/dsp - that's all. See the Sound-HOWTO. For the Perl scripts, you need several CPAN modules installing. EXECUTABLES ----------- (You need to build these before anything will happen: just type 'make') typemorse: use at the end of a pipeline to convert text into Morse: typemorse < qso.txt brainwash: sends random characters from the entire set; can be hacked to send a limited set - the ones you're stuck on. PERL SCRIPTS ------------ words.pl - needs /usr/dict/words and 'typemorse' building. Sends words of increasing size, so you get to train your ability to decode and string characters together simultaneously. (I can get individual characters most of the time, but trying to put them together into a word hasn't quite become automatic yet!) histo.pl - don't bother with this, it just dumps out a file as an "oscilloscope view" - I use it to verify that the waveforms for dit and dah are "nice". brainwashgui.pl - needs 'brainwash' built, and Perl/Tk installing. Displays the output of 'brainwash' in a big window. Maximise the window, turn the lights off, and let it just flow into your subconscious.... you are programmed to receive! LIBRARY ------- 'morse.o' and 'morse.h' can be used as a Morse library - feel free to add Morse support to all your software ! WAVEFORMS --------- After you run any of the executables, you'll get two files generated: dit and dah - they're the waveforms I use (8kHz, 8-bit). They're not particularly wonderful, so if you can come up with a better generation algorithm than gensample() in morse.c, please let me know. LICENSE ------- The software is released under the GNU General Public License. TODO ---- * Write a GUI front end for everything; configuration, etc. * Get the executables reading configuration from a file. * Write a 'big letters' output program (like banner) for those that don't have Perl/Tk * Add some slight delays to make it sound more 'natural' * There's a hook for generating white noise (see morse.c) - why not add in a battery of effects? I'm told there's a CW Pileup program that is good in this respect. (I can imagine clicking radio buttons: 'Deep QRM' / 'Dellinger Fade-Out' / 'Operator has the Shakes' ;-) ) FINALLY.... ----------- Thanks to Colin Wilson G0VAR for the idea, and good luck in your Morse training! 73, Matt Gumbley, G7JFJ email@example.com http://www.gumbley.demon.co.uk/amateur.html
That's all for now - expect more amateur software for Linux as time goes by...
