I agree. I find the articles themselves to be mostly non-critical rah-rah
stuff that the Marketing Department at the radio company could just as well
have written.
BTW Sherwood measured the SDR-5000's IMDDR3 at
5 kHz as 96 dB. It's going to be a real horse race to see if
the K3 may top that but if not it should be very close.
I don't know what the test configuration of the SDR-5000 was -- I don't think
it uses any discrete hardware roofing filters, does it? -- but Elecraft is
already claiming that the IMDDR3 at 5 kHz spacing (400 Hz CW roofing filter)
will be greater than 100 dB. (See K3 Specs page) I don't believe Eric would
have let that spec be on a public web page unless he was pretty certain it
would still be true when the final numbers come out. :-)
