[Elecraft] KX3 dimensions?

Hi All,

Shortly after the KX3 was announced and described, I started contemplating 
just what radios I own that it could replace.  Several radios I own were 
obvious candidates for replacement, but the FT-817 wasn't immediately that 
obvious.  That was due to the exceptionally small size of the FT-817, plus 
it's equally exceptional "all band" capabilities.  However, I did a rough 
calculation of volume for each radio, and I came up with approximately the 
same results that Wayne has posted (his calculations are surely more precise 
than mine).  The KX3 is, indeed, smaller!  It's perhaps a bit counter 
intuitive when you just look at the two, since the KX3 is wider and higher. 
The weight differential, which favors the KX3, is substantial.  Performance 
wise, I'm sure the KX3 will blow the FT-817 away.

Different people will have different priorities, so there's no "right 
answer".  For me, the FT-817 will probably lose 95% of it's appeal once I 
get my hands on a KX3.  The concession will be access to VHF/UHF, but I find 
my HT to be more than adequate as a supplement, and what I use mostly 
anyway.  Besides, I've always felt the FT-817 was almost too small--the 
display is hard to read, and the controls are difficult to access.  I've 
never liked the menu system on most Yaesu's anyway.  Still, my FT-817 has 
been a very frequent companion for me.  It's been a relatively flawless 
performer for a good while, and well worth every nickel I spent on it.  It's 
no surprise to me that this has been one of the most successful pieces of 
ham gear ever produced.  Nevertheless, the KX3 looks to me like the perfect 
radio for QRP Field Day and similar activities.

I will be most interested to see how the HF Packer folks respond to the KX3. 
I'm not one myself, but they are a very innovative group when it comes to 
implementing small radios.  Since radios like the FT-817 and IC-703 are 
relative power hogs compared to the KX3, I suspect that will be another very 
significant factor.  It's always a lot of fun watching these folks "do their 
thing", as was the case most recently at Pacificon.  Bonnie, KQ6XA, was 
putting out a very potent signal with her setup at Pacificon, and knocking 
off contacts one right after another.  She was getting better signal reports 
than I was using my 100 watt mobile setup!  Anyway, I can already visualize 
how HF Packers will fabricate a way of mounting a KX3 in front of them and 
having substantially enhanced operating ergonomics in the process.

As Terry, WA0ITP says, "I love this stuff!"  Even as a spectator!
