[Elecraft] KX3 current

2011-05-30 Thread Igor Kosvin
Wayne,

Is the 150mA RX current of KX3 is with the LCD display on and some level
backlight active? What if there could be option to the display go to sleep
if no knobs are touched for some time? Kind of like screen saving mode.
Could that be considered? I bet the display takes considerable current draw
out of KX3 budget. I wander if you have figured the budget, I.e. how much
each stage draws.

Thanks,

Igor, N1YX

Hi Igor,

The 150 mA target is with the backlight off. It's a transflective  
display, so it's highly visible even with no backlight, except at  
night. But we'll have a low setting of the backlight that adds very  
little current drain -- maybe 10 mA.

The LCD itself, and its controller, draw almost no power, so turning  
the display completely off wouldn't buy anything.

However, we'll be looking at various ways to cut current drain and  
will explain them in the owner's manual, as we did for the K2.
