Re: VLF: Software PSK modulation

Hi Wolf,

 

yes, I only needed a way to retrieve one number at the time from the text file. Initially I used freadln(), and later went to fread() as inserting spaces in an editor seemed easier than linebreaks. Thanks for asking, but the bulk replace  takes just a few seconds, so surely no urgent need to add new functionality.

PS: I wrote

> it might be advisable to choose e.g. 8970.1 or 8969.9 Hz for future PSK transmissions, 

 

... Freudian slip! Apparently I haven't yet fully accepted that Dreaming should only occur below 8.3 kHz ;-)

Hello Markus 
     
Thanks for the description - very interesting. I didn't take my time to study your configuration yet, but I wonder about the reason why the ones and zeros must be separated by spaces.. is it the lack of a file-access function which can read input character-by-character instead of number-by-number from a text file ? If so, this could be added easily.
