Upgrading K3 --- order of installation

[Brian F. Wruble-2]

When the K3S first came out, I ordered the new synthesizer boards for my K3, and they installed easily and worked great.

 I also ordered the KXV3B, KAT3A and the KBPF3A.  I am just now getting ready to install these.  Does anybody have advice on the best order to install them?  Or any cautions, lessons learned, etc.?

Tnx.  73 de Brian W3BW

They're kind of spread out so I don't thinking makes much difference.

Download the various assembly manuals and see if there are two or more that need common panels/parts unassembled and do those at the same time.

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

Brian,
I just added the KIO3B, KXV3B, and KBPF3A mods. As per W3FPR, Don's advise,
I did the KXV3B first, then the KIO3B, then the KBPF3A. I don't have the
KAT3A, but I do have a K3/100, with ATU, internal 2 mtr xvtr, and the 2nd
receiver.
Had to take off top cover, remove 2 mtr xvtr, 2nd rcvr, then the left side
panel (makes getting to the KXV3B install a lot easier), and then one
section of the bottom cover. None of any of the procedures are any trouble.
Just be careful doing the KBPF3A stuff. I had a couple of SMT's go flying,
but actually got them back. Pretty straight forward. Just be careful, and
read the instructions two steps ahead. Everything worked just fine when it
got put back together. I'm 80, left handed, have bilateral tremors, and
still it's a breeze. Enjoy.

73,
Rick, W7LKG

Removing the left side panel also makes it much easier to confirm that
the connectors at the rear left of the KRX3 have been mated correctly.
First-time assembly can be a little tricky, but becomes much easier
after the connector pins have settled into their correct alignment.
 
(The same is also true of the front-panel connectors, by the way.)
