I am not hopeful this can be done on a practical basis. The logic would be pretty convoluted. We'd have to snatch a small sample from the DVR Flash, then buffer it in the DSP, then push it out the serial port to a PC, which would need an application written to slurp up the RS232 data. After many iterations we could get the data across. The PC would then need a program to convert the data into some sort of recognizable, raw samples. I suspect a .WAV file is the most likely wrapper that could then be put around it. Thus, it requires MCU code for the K3, plus DSP code, plus a PC program. > I know the audio could be resampled and stored using a sound card and PC > software, but that would add another A/D conversion.

I suspect resampling would add very little noise compared to the radio link. I suspect this is the best bet, again on a practical basis. Sorry I can't be more positive :-( 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
