Re: LF: Spectrum Lab help please!

Hello Harry,

I'd also vote to update to Spectrum Lab V2.75 b11 (or later), and use 
one of the 'Very Slow CW' configs from the menu.
> Do I use "image cancelling DC receivers" 
These are only for software defined radios with I- and Q- output (either 
for the soundcard or with their own USB port). You won't need these to 
receive signals which the soundcard can process 'by itself', i.e. any 
signal with a frequency below half the soundcard's sampling rate.
Cheers,
 Wolf
