Tony, Thank you for the basics tutorial.
I would like to comment that those who downloaded the WSJT example audio files may use them to experiment what is heard. I used Audacity, a free audio editor, which plays the files and lets you see simultaneously the wave stream. It is interesting to hear the sounds and see the amplitude envelope simultaneously. I used that method when playing the FSK441 and JT6M examples, and I found it quite enlightening to compare what WSJT shows with what Audacity plays and displays. I could not play both simultaneously, but found interesting to relate the envelope with the display in WSJT 5.9.7 73, Jose, CO2JA __________________________________________ V Conferencia Internacional de Energía Renovable, Ahorro de Energía y Educación Energética. 22 al 25 de mayo de 2007 Palacio de las Convenciones, Ciudad de la Habana, Cuba http://www.cujae.edu.cu/eventos/cier Participe en Universidad 2008. 11 al 15 de febrero del 2008.
