The manual for the mod suggests it's not all that
hard to do, Ed; I plan to and I don't work with
SMT without due consideration.
In any case, you can send only the boards needing
the mod to Elecraft, not the entire K3, according
to an earlier post by Wayne

If you have never done any sm work you will find
them very difficult to handle. I have built
some boards that use that size and had to use a
magnifier to be able to see well enough to place
them. You need a very fine chisel-point solder
iron and small jeweler's tweezers to handle
them. Also very small diameter solder.
I would recommend you find a nearby ham that
does this kind of work or maybe a local two-way
radio shop that does component level repair
(though those are becoming rare). In the end it
may be better to send the radio into Elecraft
and have all the work done by them. Ham's in
the lower-48 of the US this it not that bad. For
oversea's hams shipping and customs becomes a
real hassle/expense.
I will make my own mods but I regularly build sm
equipment and have the necessary equipment.
Saying that, 0403 are still very difficult for
hand replacement.

the kits I build use 0805 & 1206 chips.
