[TenTec] Jupiter display backlight

Steve, Thanks for the reply.

The Delta II has an LCD display with an AC powered electroluminescent panel
behind it for illumination.  The Jupiter ad in QST shows a display that
looks like a larger and more complex delta II display, thus my concern.
The problem with the Delta II was that the intensity of the EL panel behind
the LCD would fade over time, eventually rendering the display marginally
readable under most conditions.  I was able to acquire an engineering
experimenters kit from the manufacturer of the original panel and cut a
piece the same size as the original.  Unfortunately it too is fading after
only about two years of very intermittent use, probably less than 100 hours
of on time.

So the question remains as to whether or not TenTec addressed this problem
for the Jupiter.
