[Elecraft] Options for KX3

[John K7JLT]

I have all the options plus big heat sink and the side handles/cover (purchased after the front got scratched in my day pack. 
In order of usefulness:
 Antenna tuner (integrated very well with radio) works well with random length wires when portable.
 Filter (a must have for field day operation but only used then)
 Hand mike (even smaller/lighter would be better when portable) never use the up/down buttons.
 Battery option (only used to extend my portable operating time when my external Lipro battery runs down).
