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. I would have thought using green LEDs would have been a more efficient use of precious milliamps. The display is just a seven segment array and has a manufacturer's part number, although it is possible it is end of line. I don't think it is custom, or at least not at the time of the original design. The real problems with making the change are that the LED's are integrated into the diffuser and the diffuser is behind the, unsocketed, display. I doubt you could change the colour, except before the first build, without destroying the LCD panel. It is also possible that the diffuser assembly is difficult to source; there is no manufacturer's part number for that. -- David Woolley K2 06123 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
