Joe,
Thanks for addressing what to me is the core issue
with any rig -- performance. A "bells and
whistles" user interface -- and that can be a
matter of personal preference -- may sell a lot of
rigs, but to me performance is key in selecting a
base station transceiver. I can compromise
performance for special applications like portable
ops, QRP, etc. but I want my main station radio to
be near the top of the list in the Sherwoodian sense.
After looking at the information here
http://www.icomamerica.com/en/products/amateur/hf/7300/default.aspx
an in the pdf file linked here:
http://www.icomamerica.com/en/downloads/DownloadDetails.aspx?Document=746
and from the general appearance of the Icom-7300
(ports, controls, etc.) I don't expect it to be
near the top when Rob Sherwood tests it. Of
course, it hinges on a number of factors --
including those you brought up below -- and I
could be surprised. Even so, while I'm not
spring-loaded against SDR rigs (the KX3 is
basically an SDR radio, after all, and I enjoy
mine), I can do without a touch-screen interface.
But I've been at this for 62 years now, so maybe
I'm just "old fashioned" :-)

The question will be what quality ADC Icom uses
in the front end of the
7300 and how clean (phase noise) they can make
the synthesizer (clock).
If they have enough ADC bits to provide dynamic
range, their claimed
synthesizer phase noise comparison should put
the 7300 at about the
same level as the Ten-Tec Eagle in the Sherwood
"chart" (e.g., 92-95
dB IMDDR3, -134 dBc @ 10 KHz phase noise,
125-130 dB 100 KHz blocking
[ADC limited]).
If Icom "cheaps out" and uses an ADC with
limited resolution (number of
bits) like some of its commercial products, the
7300 is likely to fall
way down the list - into the neighborhood of the
IC-7000 or FT-2000.

Personally I feel that a touch screen is a must
in a "stand alone" (no pc
needed) SDR, as it allows the future
development and or creation and use of
soft keys for functions that we may not even
think of today. As for the
IC7300, most of the time you will likely be
using the most commonly used
functions which appear to be tied the physical
knobs and buttons, and not
have to touch the screen that much.
SDR is the way of the future, heck it is the
way now, and I think this is
Icom's way of dipping their toe in the water
and not upsetting their fan
base by introducing an SDR in convention
looking hardware. I am confident
that they will be releasing a whole line of

I have owned a K2 a couple K3s and KX3, I love
Elecraft and love supporting
a made in North American brand, but frankly am
confused as to why Elecraft
isn't leading the pack on stand-alone SDR?
