Re: [Elecraft] K4 Observations

I think your observations are spot on in most respects. While the basic K4 is certainly going to be a great radio, it will likely NOT have the strong signal handling characteristics of the K3/K3S. There will still be the likelihood of A/D clipping suffered by virtually all 16-bit SDRs in a

Way down in the specs you have the sampling rate, 122 MHz and I don't see a spec for the A/D Equivalent Number Of Bits (ENOB). That is a useful measure of the dynamic range, as most if not all 16 Bit A/Ds have a lower number of ENOB. Perhaps these should be more prominently advertised as they can
