[Elecraft] Update to KSYN3A FAQ (some measured dynamic range numbers)

[Wayne Burdick]

Hi all,

I've updated the KSYN3A FAQ with the following information regarding testing of a K3 with the new synthesizer performed by Rob Sherwood, NC0B.

Q: What is the approximate 2-kHz dynamic range (IMDDR3) of the K3 when using the new synthesizer?

A: Our tests show in excess of 105 dB with the narrowest filters, though there are many factors, and this should be considered approximate. (A very robust test setup is required to make these measurements.) Rob Sherwood tested a K3 with a KSYN3A and obtained the following results:

    2-kHz IMDDR3 with 200-Hz roofing and DSP filter = 106 dB
    2-kHz IMDDR3 with 400-Hz roofing and DSP filter = 103 dB

Rob will be posting this information in his receiver performance chart (http://www.sherweng.com/table.html) after he completes his full suite of tests.

The above numbers were used with Rob's permission.
