Doing all additions at once

I now have a lot of various extras and mods to add to my K3 - KRX3, KDVR3, all the mods

- all because I haven't had the time or need to practice SMD or are waiting for the last bits (some of which I've asked Elecraft to hold so they ship as one) - all of which are going to arrive soon :-)

It looks like there are some many dependancies on taking this off and that apart, that it might be easier to do them all in one go - but what are the risks of me missing something and then not being able to figure out what that something is?

In the software world, we never (should never) make multiple changes without inter-step testing - but to test at each stage means putting it back together again, using it bit and then taking it apart for the next bit.

What do people think here?

In theory, there is no difference between theory and practice,
but in practice there is.

Re: Doing all additions at once

Dave,

That question has a 'double edged sword' answer, so "it all depends".
1) Either you make an error in applying the mod -
2) OR (IMHO more likely) you create some unrelated problem when you
reassemble the K3.

Reassembling and checking after each mod will reveal the first type
problem, but it certainly will compound the likelihood that you will
create a problem of the 2nd type. And doing the troubleshooting is
mentally difficult because one usually associates the problem to the mod
that was installed.

Unlike software changes, these hardware changes have been installed by
several users and the side effects (if any) are well known - it is not
like making a change for the first time.

My vote is to do them all at once, but YMMV depending on your confidence
level.

Thank you Don, I'm aware of your considerable experience with all
things Elecraft and will take your valued advice - it will be easier
that way anyway.
If anything over confidence is my problem :-)
