Reading over these comments, I'm surprised that an internal ATU is such a big deal. Besides the Elecraft, nearly every other radio's internal tuner takes the radio from tolerating about 2:1 to about 3:1. Not all that useful. For those situations where you have a non-resonant antenna, manual QRP tuners are cheap, tiny, consume zero power, and are capable of far, far more than any internal tuner. Take a look at the Emtech ZM2, the PA's Sota tuner, etc. If you need to push one button, Elecraft's T1 is an option too. What cannot be fixed with a little tiny box attached to the side would be current draw and heat dissipation. Here's hoping the rx current draw is considerably better than the 7300, and, that it can actually tx 10w all day on heavy duty-cycle digital modes without overheating. Not achieving one of those would pretty much be show-stoppers for portable digital operation on battery.
