First-off my apology this reply is so behind in time. My main
computer was under re-build so was having to use web-based e-mail to
access my e-mail and the reflector would not recognise me as
registered for posting replies.
I think which parameter is most significant depends a lot on the use,
whether that be HF contest, DX, rag-chew, and what mode: CW, SSB, or
one of the digital modes. Is this a strong-signal environ or super
weak-signal?
Across the board (Sherwood table) the KX3 is impressive (when on
takes into what challenges a direct-conversion receiver faces). Also
the entry cost for a new radio is pretty great for being on top of the list!
For my favored modes which all involve weak-signal reception the -144
dBc/Hz LO noise is a big plus! I do not encounter nearby large
signals so the other two parameters are less of an issue.
But I will use the KX3 in a wider range of ham use so the
strong-signal characteristics will be definitely nice. As to the
individual selling his FT-817 (being made harder) ....why I sold mine
last winter ahead of the game.
Aside to Wayne: Sherwood numbers great stuff to add to my product
review paper on using the KX3 as IF radio for mw. The mw gang hold
great store by low-noise LO's. Next they look at LO freq. stability
so a pending EXREF will be significant for purchase decisions made by mw hams.
I'm hoping we can see the KX3-2M before the presentation in San Jose
(MUD-2012) Biltmore Hotel, Oct. 19-20. 144-MHz is the most popular
IF for mw equipment.
