[Elecraft] FW: [Elecraft-K3] K3S Comparison table finalized (linkattached)

[Jamie WW3S]

and that was my real life experience in last weekends 160 contest....I felt 
the 7610 could hear just a bit better than the K3, especially those ESP 
signals right at the noise.....I worked several DX I wouldn’t have with the 
K3.....BUT.......in crowded condx, the 7610 thumped and pumped when someone 
was close to my passband, even with a 200 hz filter enabled. I didn’t get 
any of that with the K3, its front end is like a brick wall......to be fair, 
I had the noise blanker enabled on the 7610, which some comments post 
contest said that could be some of the thumping I experienced.....

I'd be interested in seeing a similar comparison of the K3S to the
FlexRadio.

My two cents:

radio at #1 cannot be reproduced with current software.

Clarified recently in footnote "y" of the RX performance table.

reason. The difference in 2 kHz dynamic range is 106 dB compared to 98 dB.

The table is sorted on 2 kHz IMDDR3. However, the table also shows dramatic
differences in blocking dynamic range. For example, the K3S is 20 to 30 dB
stronger in this regard than all of the direct-sampling radios in the table.
This is due to the K3S having narrow-band filtering (crystal filters) ahead
of the ADC. This can greatly reduce desense and other artifacts in any
high-signal situation (Field Day, KW neighbor, multi-TX station, etc.).
