[Elecraft] Comparisons K3S/KX3/K2 etc?

[Matt Maguire]

The Rob Sherwood chart is sorted by narrow spaced dynamic range (second last column). K3S is at 107dB, KX is at 104dB, and K2 appears twice, 80dB for the new model and 70dB for the older model. I presume if you apply the mod kits to an older model K2, it will bring the performance up near where the newer K2s sit.

Rob mentioned in one of his presentations that for CW you need a better receiver that for SSB, and that ideally you want at least 80dB narrow-spaced dynamic range when working weak CW stations in crowded contest conditions with strong stations nearby. An up-to-date K2 meets this criteria, but the FT991 is quite a but further down the chart at 71dB. Don’t know where this Icom IC7300 will fit in, but I think, like the Flex radios, it is a direct-sampling SDR architecture, and it will be very interesting to see where it ends up.
