qrq is an open source Morse code
trainer for various platforms and operating
systems, similar to the classic DOS
version of Rufz by DL4MM.
Its not intended for learning telegraphy (have a look at
http://radio.linux.org.au/ for CW learning software), but to improve the
ability to copy callsigns at high speeds, as needed for example for contesting.
After starting the software and setting up the parameters (speed, CW
waveform...), the program sends 50 amateur radio callsigns. When entering a
copied callsign correctly, the speed increases, otherwise it decreases. Points
are awarded for correctly copied callsigns, depending on the speed.
A scoreboard/toplist exists on the authors website, at
http://fkurz.net/ham/qrqtop.php. The local toplist file can be synchronized
with the online toplist with
qrqscore -d and you can upload your own top scores by invoking
