Did you notice the reported 6M sensitivity number?
1.25 microvolt compared to 0.16 microvolt on 1.8-30MHz.
This may be a misprint as the MDS values are close to the same.

You sure don't want one of those noise

Just to clarify for

The transmit IMD specs are pretty poor as well ... and the interesting
thing is that neither deficiency was even discussed in the narrative
portion of the review.

aware of is an Analog Devices 16 bit, 100 Msp/s one that ain't exactly
cheap. To approach the dynamic range in the KX3

I cant say that there is much more I want in a radio that the K3 or the
K line can't offer now. Mind you if there are some cool toys coming
for the K3... well new toys are always fun!

If you are waiting to see what the Flex 6000 is like you might take a

No need to speculate. There is no such project underway at Elecraft.
Direct RF-sampling receivers, for all their technology, still lag well
behind the K3 in blocking dynamic range, and probably will continue to
for years to come. We're quite happy with our superhet architecture.

Given the advances in direct RF sampled SDRs (currently available QS1R, soon to
be released Flex-6000, etc.), Elecraft must be quietly working on on an RF
sampled K4 SDR. Maybe we will see an anouncement in May at Dayton? I am
wondering if I should take the leap with the Flex or wait for
