Thanks for this explanation. Now I'm sure the K4HD will be at
least as good as the K3S and probably better.
Watching Elecraft is like watching a really good magician. With
both, you expect extraordinary things. However, with Elecraft, I
like to know how it is done. :-)

The K4 is always doing direct sampling for panadapter purposes.
If the HDR module is turned off or is not present, the K4 also
does direct sampling for demodulation.
If the HDR module is turned on, two additional ADCs are used,
right at the outputs of the crystal filters (oversimplifying a
bit). The original two ADCs are still being used for the panadapter.
