[Elecraft] K3 LED/LCD brightness

[WILLIS COOKE]

You have a much more sensitive ammeter than I do Drew.  I draw about an amp with the back light on 4 where I usually keep it, but I can;t see the difference if I change the setting to DAY.  70 ma at 13.8 V is only about 1 watt.  My desk lamp has a 60 watt bulb so you would save more money to turn off some of the lights in your ham shack.

Still, it should be possible to allow you to adjust the LEDs with a software change if the software gurus work it to the top of their priority list.
