K1 backlight kit
Locked
 
|
Good evening all,
I’m looking for a LCD backlight kit for the K1. I don’t see it listed on the Elecraft site anymore and am kicking myself for not picking one up sooner. If anyone has a kit that is no longer needed, I would be interested. Please contact me off-list. 73 de AG7TX...

If you can't find a kit: I modded my K1 to illuminate the LCD back in '03, before the mod kit was available. It's pretty easy to do (a white sticker, two leds, and a resistor) and works very well, but it does require a transreflective LCD in place of the original reflective one supplied back then. I tried the mod with original LCD and it didn't work IDK if later ones came standard with the transreflective LCD. If you have or can get a transreflective LCD, I'd be happy to describe the mod and email some photos that detail the mod and show the results.

Morning Lou, I looked on the Elecraft site and the part number for the transreflective LCD is E600015. A search for that part number on the site turned up nothing. So they don’t appear to be stocking that part anymore. If someone reading the reflector knows the source for that part, I will see if I can find one. If not, I found this approach — https://bit.ly/3fgvtL2 — to adding a backlight to a built K1. With a little tinkering, the latter should work as well. Thanks Lou!

The link in the email you sent is similar to what I did. It did not work with the original LCD. Putting a white sheet behind the original LCD did nothing as it was opaque. I had to get a transreflective one, the key here is it's translucent to permit back-lighting. It was long ago and I don't have the info where I got it. IDK, but it is possible that production switched to using the transreflective type at some point. I'll pm you some pix.
