I composed a long reply on my experiences to find my web-mail had disconnected so
all was lost with reconnection.  So here it is again:

I am using my KX3 probably 90% in the shack as second radio to my K3.  K3 has heavy
lifting duties on HF and with my several VHF+ transverters.

I do plan to set up the KX3 for mobile once a quick-change mount is available and
may add a 100w HF amp.  It will get primary duty on 2m-FM using an add-on linear
(either 35w or 80w).

I did encounter highly distorted audio on my initial turn-on of the KX3. That was
using the internal speaker.  It happened on strong signals a couple more times and
has not occured since?  I figure the radio was just stretching on initila wake-up!
I do normally run with my Harmon-Kardon computer ampified speakers which improves
audio quality (though the speakers were never spectacular).  MY K3 internal speaker
leaves me luke-warm but I have it connected to a 8-inch 1950's National Receiver
speaker which gives great audio with the K3.

I bent a piece of aluminum plate so the radio is mounted at 15-degree uptilt on my
wooden radio shelf (console) using the prethreaded hole for the paddle which I
opted not to buy as I have a Bencher-2 in the shack.  Most of my serious CW sending
is done by computer anyway.

Overall I am favorably impressed.  The FT-817 which was replaced by the KX3 never
impressed me for HF reception.  The KX3 sounds almost as good as my K3.  I will add
the 2m module and EXREF options when available.  I also use the small radio for
portable operation (aka mountain-topping) for VHF- mw.  I am writing a review for
the Microwave Update Conference this October on that application.

I figured on some start-up "bumps"being it a new product.  But I am confident that
Elecraft will come forward with upgrades via firmware.  That is the nice part about
having a SDR>
