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" :-)

73, Phil W7OX
