Maybe they realize the technology is at least 5 years away from being competitive. Everybody is ignoring W4TV's 800lb Gorilla, ADC overload.


What suggests you that direct-sampling SDRs are 5 years away from being competitive? Elecraft will likely have moved to this architecture in less time than that to remain competitive. I suspect that one of the reason Icom stuck with the superheat on the IC-7851 is because this product was already in production by the time they made the decision to design a direct-sampling SDR. Now this is all speculation. What matters is that many of us who have high-end direct-sampling SDRs haven't experienced the overload issues. I don't doubt some operators have (maybe W4TV one of them), but these are probably isolated case. BTW, all receivers have weakness (every design has trade-offs), including the ones designed by Elecraft (I can hear images on KX3 sometimes). Just that you know, K9CT has one of the finest contesting station in the US. He has switched to direct-sampling SDRs (Flex-6700). Just ask him if this architecture is 5 years away from being competitive.
