[Elecraft] KX3: How much space inside?

> But don't sell the 703 short.

Dave, my experience with the 703+ was a bit less enjoyable than yours. 
Here's why:  QSK performance was not only poor, it was down-right 
objectionable on the air.  The 703+ suffers from extreme "dit-shortening" 
and chirp from T/R synthesizer transitions when in QSK mode.  In semi mode, 
CW is fine.  But, the 703+ cannot handle fast T/R transitions.

One cannot hear this effect while listening to the CW sidetone.  The keying 
artifacts require listening on a separate receiver, ensuring that the 
external receiver is not being overloaded, NB turned off, etc.  For me, 
owning the 703+ was one of the worst QRP experiences I've had.  That, added 
to the relatively high Rx current consumption and high case temperature 
caused me to sell it shortly after purchase.

The ability to produce fast T/R without artifacts is now at the top of my 
list when considering any new rig whether it's QRP or QRO.  It tops all 
other performance parameters. It's *the* reason why I have not gravitated to 
most other SDR rigs.
