[Elecraft] (KX2) - Randomly Powers Up "Weird"

[stan levandowski]

Thanks, Bill.  The KX2 doesn't actually have a "sub" receiver; if you 
mean dual watch then no, it's rarely engaged unless I'm working split 
DX. It's not a VFO A/B issue either.  I guess I should update my 
firmware....I only work CW and my needs are simple so I've refrained 
from updating so far. The little rig and its amp work so well.....I'm 
always afraid of screwing something up!!
