K-3 upgrade question

[louis a. ives]

I have received all the necessary parts to begin updating my K-3 to K-3s.   My K-3 has all options except the second receiver. I need to know if there is a  suggested sequence to perform the updating. I am trying to not have to remove items more than once if at all possible.

Well assuming you have all the mods, you should have the assembly manuals as well. I'll assume you are replacing the Synth board, the Full coverage mod,  the KIO3B, the KPA3A and the KAT3A.

Not having books in front of me, remembering the assembly, I would remove Top and Both Bottom panels. Also the Side Panel with handle.

Now remove everything you have a replacement for. You may need to remove other side panel and back as well. See what access you need for removal.

Now re-assemble your radio in the reverse order of removal .

Doing more than one install at a time is quite possible and can
be a significant saving of time and effort. But to a certain
extent, you will be synthesizing your own instructions.

All of these installs break down into three phases: Disassembly,
install, and reassembly. The way I like to approach the task is
to do all the disassemblies first. This gets the most buried
component exposed. Do the install for that component, and any
other, less buried components where it seems to make sense.
Start reassembly and install an other components when they seem
to make sense. After you have completed most of the reassembly,
you can power the radio, perform any settings called for in the
install manuals, and test everything. When something doesn't
work, try to figure out why. The trouble shooting guide in the
K3 manual can be a big help here.

In my trips into the depths of my K3 I have encountered TMP
cables not completely plugged in (caused low output on the 2M
transverter), used the wrong wiring diagram for the TMP cables
with the new synthesizer boards (caused total failure to work),
and a unplugged TMP cable to the second receiver (which didn't
work as a result). Notice a pattern. Be careful with your TMP cables.

Some of these I was able to resolve myself and some were
resolved with the aid of Elecraft tech support (Thanks!).

Enjoy working on your radio. Working on it is a lot more fun
than shipping it off for the upgrades.

I would suggest you start by removing the top and front bottom covers as
well as the left side panel.
Then remove the subRX assembly.
You can install the new synthesizer boards at that point - do not put
the subRX back in until you finish the other upgrades.

Then you have a choice - deal with the Front Panel and DSP assembly or
deal with the parts in the rear.

If you have an older K3 and need to do the 'gold pin' replacement on the
PA, you will end up removing the entire rear panel - so do the 1 amp
increased current for the rear panel AUX 12V while you have the rear
panel off.
You can also do the KIO3B install with the rear panel off.

If you are doing the KBPF3 upgrade, do that next, and do the KBPF3 in
the subRX if that option exists.

While you have it open, there are other upgrades to the RF Board - 2
associated with the audio amp and several others.  You did not state how
old this K3 is, so I don't know if you need to install these other mod
kits and Application Notes.

If you have a very high confidence level in your ability to put it all
back together correctly, you can be successful in "doing it all at once".
However if your memory of "which part fits where" is not excellent, I
suggest just doing the upgrades one at a time - and follow the
instructions for each (but do not re-install the subRX and top/bottom
panels until all the other upgrades are completed).

After you have upgraded 2 of them, you will be equipped to easily "do it
all at once", but be cautious doing it for the first time, and "do it by
the instructions" to be on the safe side.

Sorry for the misinformation below - change KIO3B to KXV3B.
