[Elecraft] Upgrading K3 --- order of installation

[Don Wilhelm]

Brian,

Those are in physically different areas of the K3, so I don't think the 
order is significant.

If you have the KRX3 installed, I would suggest adding the KBPF3A first 
(don't forget the added capacitor to the regulator output), and then 
leave the KRX3 assembly out until you have installed the KXV3B.  There 
is no electrical significance to my suggested order, but without the 
KRX3 in place, you will have more "finger room" when installing the KXV3B.

Hint on the KXV3B - remove the left side panel to give you more access, 
and slightly form the male pins of the KXV3B to the K3 rear before 
trying to insert them into the header.  Put the pins on a flat surface 
and apply a bit of pressure - you only need to bend them a bit.  You 
will understand if you first try to put the pins into the header before 
bending the pins.
Of course, you could remove the entire rear panel to get the pins to 
align, but that is an extreme solution to the problem.  The slightly 
bent pins will not pose any problem once the KXV3B is fastened in place.

73,
Don W3FPR
