KX1 with 3080 -- first build

[PGSchreier]

Hi,

I'm working on a KX1, and I also have the 3080 module.

I'm thinking it's best to do the 3080 mods as I build the KX1 -- or are
there some good reasons to build the "bare" KX1 and then do the mods (I
hate removing components!)??

tnx

The best advice is to build it and test it, then add the 3080. I did it all at once and had a small issue with the 3080...mostly due to trying to keep the 3080 toroids really tight to the pcb...solder joint.

Paul,

It all depends on your building confidence level.  If you are quite
confident in your work and have the ability to merge 2 sets of
instructions together, then the answer is "yes, do it" - but if this is
your first time attempting such a shortcut, be careful - once you go
down that path, there is no looking back and in case of trouble, the
results can be confusing.

However, if your skills and experience are limited, then the answer is
"Do it like you are instructed".

If you wish to proceed with the combined changes and minimize removing
components, Install L6 on the back of the board, do not install C26,
C27. C1, and L7.  Then do the procedures shown in the KX3080 manual
through page 7.

When you have checked out the operation of the KX1 on 40 and 20 meters,
continue with the rest of the KXB3080 instructions.  You will have to
remove L1 and L2 from the PC board, but that should be a minor
"inconvenience"

Hi Paul,


I came to my KX1 after having successfully built several Heathkits back in the day, but nothing in the intervening 25 years. So I counted myself as starting over with the KX1 as my first build. I found it helpful to build the basic radio first, use it for a bit to get the hang of it, then move back to the mod. Yes, you have to unbutton the case again and remove some parts, add some others, and scratch a gap in a circuit board. I wasn't sure I wanted to do that either. But on reflection I found it easier to follow one set of instructions at a time, rather than try to splice one set into another. For me, it kept things clear and direct. I realize your mileage may vary...


With best regards,


Pete
