Greetings all, Murray wrote: ... or use SpecLab, which has a complete QRS / DFCW generator using the soundcard. Can be set to any symbol rate and audio frequencies you can think of (also very high frequency shifts, to compensate the divide-by-something hardware).Folks,I find it difficult to understand why one would want to generate DFCW with up-down buttons, when there are plenty of ways to do it reliably with audio.It would be quite trivial to write a BASIC program that generated sound out the PC speaker, and of course sound card methods would be straight-forward to one of the Windows programming experts. A few years ago I wrote a DOS program which does this type of thing. Regards, Wolf . |
