For those of us who use the K2 as a base station rig, or connected to a
hefty battery (like mobile installations), it's easy to forget that one of
the design criteria of the K2 was efficient use of power for
emergency/portable use. The other Excellent performance numbers were
certainly in mind, but we "tied-to-the-grid" operators often forget the
battery efficiency design goal.
Sure, Wayne and Eric could have used different R, C, P and J numbers on the
various boards to make this sort of error impossible, but the extra battery
drain of utilizing them wouldn't have been worth the effort. Instead of
P1-P7 (Control) and P1-P6 (RF), we'd have P1-P7 (Control) and P8-P13 (RF),
driving the receive current up by 28%!
Similarly for resistors. Rather than R1-22 (Control) and R1-116 (RF), we'd
have R1-22 (Control) and R23-138 (RF), again, driving the efficiency down by
another 16%.
I could continue with analyses by Capacitor (22%), Diodes (2.25%), etc., but
what's the point? We need to support our battery-bound brethren.
Don't forget the weight factor too! The weight of the silk-screening of all
those extra digits must add up to significant heft, possibly even
measurable<g>

An interesting post......who would have thought there were 2 x P5's ?

I see there are 2 x P6's as well. It would be interesting to transpose
them ........ Cheers....Ron ZL1TW
