Dave and all, It is my understanding that the bandwidth of the KX3 I/Q outputs will be "greater than 40 kHz", but certainly less than the 200 kHz width of the P3.
That fact reduces the sampling rate requirements of the sound card - I believe most on-motherboard soundcards will handle the width and sampling rate required. The noise is quite another issue - but salvation may be had if the I/Q output levels are line level - the soundcard problems for onboard soundcards are magnified when microphone levels are mixed with digital noise. In other words, the KX3 I/Q outputs MAY work just fine with most soundcards - the real answers remain to be seen, and are dependent on the particular computer soundcard you may have. 73, Don W3FPR On 1/9/2012 5:59 PM, David Gilbert wrote: > > > Regarding sound cards for SDR use, certainly the great majority of cards > out there would have major deficiencies ... most especially for noise, > but also for dynamic range and sampling rate.
