[Elecraft] RP2 Orientation for KRC2

[Don Wilhelm]

Brian,

If you cannot locate the pin 1 designation on the silkscreen, then look 
at the solder pads.  In most cases, the solder pads are rectangular, 
except for pin 1 which is usually round.  There are some instances where 
most of the solder pads are round, but in that case, pin 1 is 
rectangular or square.

On the component, the dot may be any color - usually the same color as 
the value marking.  If you hold the R-Pak wih the pins down and the 
value designation facing you, pin 1 is normally on the left. The color 
of the dot can change from manufacturer to manufacturer, and even from 
time to time with the same manufacturer.  Yes, it was black when the 
manual was written.

73,
