[Elecraft] K1 Battery Voltage Readout Question

[Jozef Hand-Boniakowski]

I completed my K1 on 2/26/07 and have worked 44 countries, 27 states and 
285 QSOs.  I love the radio and it has performed well.  I have a 
question about the battery voltage readout and was wondering if this is 
typical or not.  When I put the display function into battery voltage 
the LCD reads battery voltage like it is supposed to (i.e. 12.6) and the 
display blinks every second or so.  What I also notice is the the 
attenuator (ATTN) LED blinks fast ever so slightly at about 10 time per 
second.  This blinking is extremely dim even in darkened conditions but 
noticeable.  Is this normal.  It only happens in the battery voltage mode.
