[Elecraft] LC Back lighting & location of new K3 mods

[Doug Person]

Where would I find the details for the mods that are required for the 
new firmware?  Also, what is the source of the LCD panel back lighting? 
I hope the answer is LEDs.  I like to just let the K3 stay on all day 
and I'm hoping I'm not running down the back lighting bulbs. If they're 
LEDs then it probably won't make much difference.

tnx & 73, Doug -- K0DXV
