Greetings all,

A configuration file and a detailed 'step-by-step' guide to configure SL 
is 'under construction', since I just finished another project.

The main complexity is the need to compensate / eliminate the 
soundcard's sampling rate drift (i.e. oscillator drift),
which -at the moment- calls for a suitable GPS receiver with sync-pulse 
output, or a similar drift-free reference which is inside the frequency 
range of today's soundcards.

Under that aspect, a dedicated data acquisition hardware as suggested by 
G4JNT would be a good alternative.
But all of those possibilities require a bit of extra hardware...

Cheers,
    Wolf  DL4YHF .
