Re: [Elecraft] Amber display for the K2?
I have a Pace de-soldering tool so taking off the display is not really an issue, but agreed it would have been easier before the display was installed. As for the diffuser, If needed I have a CNC mini mill so I could cut a piece of Plexiglass and I have a nice sample pack of photography gel filters that include many colors and some various defusing films. I was trying to avoid having to build one from scratch, That being saig I may just use it as is for a while. After all the face of the K2 is half grey so it does not quite match the K3 as it is.

I'd never really thought about the colour, but I think it is basically the natural colour of the combination of liquid crystal and polariser. It's not the narrowband green that you would get with a green LED. Especially if you add in the fact that white "LED"s are really narrow band blue LEDs with broadband yellow phosphors, so are not peaking in the green, natural variations in colour vision, or colour vision defects, could easily cause the colour to be treated as a yellowish amber, rather than a reddish green.

Re: [Elecraft] Amber display for the K2?
Interesting I build a K2 Years ago SN in the 3500 range and just built a new one (just finished it). Both with Green Backlights. I was thinking that it would be nice to change this one over to an Amber backlight so it matches my K3 better. I may just need to find some closely matching LEDs or just leave it as is. I figured it was worth a shot.

Re: [Elecraft] Amber display for the K2?
K2 #1239 is green at night when the internal light is on, more gray than green in daylight. But it definitely is not amber. I suspect that is a function of the LED's that are lighting the screen, which appears to be lit from the side, not the back. 73, Guy K2AV On Tue, Apr 4, 2017 at 2:34 PM, Fred Jensenwrote: > The main display on my K2, S/N 4398, is VB on NVB [Very Black on Not Very > Black].
