[Elecraft] KPA500: birdies on 6m from LCD backlight

[KD7PY]

his is my post of Nov, 15 2011:

This is what I found as the source of the birdie's in the amp.

with the LCD BRT set anywhere from 1 to 8 the birdies are there.
with the LCD BRT set to DAY the birds are gone..

I have been working all day with Dale @ Elecraft with this and just sent him
a e-mail of what I found.
Dale has been very involved in this trying to track this down..
 
now we need  to see just what kind of fix we can come up with..

I can't Thank Dale and crew enough for the support they have put into this,
as it appears everyone got envolved.

Thanks Again Dale @ crew..

Elecraft sent me a new Front board , as it is due to a bad filter cap on the
display driver
