[Elecraft] K3/100 or KX3 with all the options

[Wayne Burdick]

Hi all,

The KX3's LCD is identical to the K3's, except that it its polarizer  
optimized for "6 o'clock" viewing, similar to that of LCDs in digital  
multimeters and other instruments with a top-facing display. Since the  
LCD has a low muliplex rate, it has very high contrast, and as Erik  
observed, works with a wide range of viewing angles -- but not from  
above the display.

The contrast is not presently adjustable, but we can add this if  
warranted. This may extend the range a bit further.
