I have been very intrigued by the KX3 (actually all the Elecraft products). I've been a little reluctant to go in that direction for a few reasons. You touched on one - ease of use. I'll have to look into what operating that radio would be like from my PC. They will be in the same place, so that's not a difficult thing to do.
The other concern is that by the time you buy the KX3 itself, perhaps some options, plus the 100w amp it gets a little expensive. I'm sure it's a very nice setup, just not sure I want to put that much into a first base station.
Thanks for the advice, and I'll look into that option some more.
