Re: K3 LED/LCD brightness

Actually, I sometimes like to use the "day" settings at night when I
don't necessarily need to be watching at the display-- the LED
brightness is way too bright then. It would be nice to be able to turn
them down also.

Funny thing... as much power is consumed when LCD Brt is set to "dAY"
(backlight = off) as when it is set to max. I guess some of this is
due to the extremely bright LEDs in the day settng.

Now I see what you are talking about Drew. I never paid attention to these settings other than LCD Brightness and Back light Brightness. I am not sure what your reason for turning the back light off might be. If you are operating in sun light I don't think that you can see the back light on the LCD with a setting at 2 and the current drain is small enough that I don't detect it on my power supply ammeter. I have never tried to operate my K3 outdoors and I am simulating it by aiming my 75 watt desk lamp at the LCD, but that looks OK to me. Is that a possible work around for your?

Re: K3 LED/LCD brightness

Cookie, I can see the "dAY" display pretty well with my normal indoor
operating position lighting, but the LEDs at this setting are
irritatingly bright.

Sometimes during the day I have the rig on, just scanning a band or
listening to a SWBC station while I'm doing something else around the
shack; don't really need the display on then anyway.

The ma difference as shown on the K3 between LCD Brt "2" and "dAY" is
about 70 ma. (No, I'm not a global warmist or anything... far from it.
Just thought it was interesting...)

Re: K3 LED/LCD brightness

In reply to this post by drewko

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.

Me either nor do I recycle but those LEDs being on when the display is off
seems rather odd.

Yes, I'd like that too, if it's possible to implement it. Fingers crossed.....
