Here's a little tidbit that Wayne dropped a few days ago about what type of power output to expect from the new Elecraft KX3 HF rig when operating on battery power:
I'll continue to provide more information as it becomes available.
Our target is 5 W at 9.6 V (NiMH pack). Nonrechargeable lithium AAs or fresh alkalines provide more than this, and of course you'll get 10 W or greater with an external supply. Currently we hit 15 W on some bands with a 14-V supply, though we'll probably reign this in to 12 W
The radio will continue to function down to 8 V--useful in an
emergency--but with greatly reduced power output.
I'll continue to provide more information as it becomes available.
