Dear LF Group, anyone in need of a simple, clean and stable PSK modulator, driven by any old DOS PC without a soundcard? Look at http://members.aol.com/df6nm2/SerPSK.zip (141kB) for a description and a software (including Basic source) which sends dithered bit patterns to the RS232 data line, feeding a balanced modulator and linear PA through a crude R-C lowpass. This solution has worked successfully at the DI2AG beacon for some time last year. Happy experimenting Markus, DF6NM |
