Icom IC-736

S-meter transparent

First I designed the new scale. I has the same layout and proportions as the original black scale. Then I printed the image on a matt polyester foil on the common desktop laser printer.

Finally I replaced the original black scale with the new transparent one.
As I wanted to keep the similar color of the s-meter as the LCD display the LED diode behind the scale is now:
Diameter: 4.8 mm
Angle: 150
Color: yellow (590nm)
250mcd @ 20mA
