The lamp in my (old) CDE Rotor Control Unit burned out. I opened the lid
and found the lamp had melted a hole in the plastic meter. To make a
long story short....I called Hy-Gain and found out this is pretty common
and they recommended a 28 volt lamp - that should burn cooler. I picked
up a smaller 28v lamp at Radio Shack. It is not as bright and I now have
a moonbeam display.

The tip is open your control unit to see if the lamp is starting to melt
the plastic meter. Don't wait for the moonbeams to change to the smaller
28 volt bulb. BTW, I understand some have been know to have melted the
cover as well as the meter. It is pretty easy to check...just remove
four screws and take off the cover.

I now wonder if the use of a White LED may be a better solution to this
problem?

ps: The fix for moonbeams is a $69 replacement meter! I am learning to
enjoy the moonbeam lighting.
