 have heard mixed opinions regarding using the Kester
"no-clean" (not the water-soluble) solder to build Elecraft 
kits.

Hi

This was covered rather extensively a month or two ago, but new people are 
always joining so I will do it again.

The official Electaft position is to use Multicore 60/40 or 63/37 rosin core 
solder because it is easier to make good joints than the noclean made by 
Kester. The Multicore has a more active flux and does a better job of 
cleaning the oxides on the joint and is better for stripping and tinning the 
torroids. 

However I have used noclean solder for many years and have no problems with 
it. I have built 6 K2/K1's with it and I have an installed base of over 
15,000 boards in the field built by my company with it. It looks better 
because the residue is clear and does not show. If you are going to clean the 
boards (also not recommended by Elecraft) the noclean removes with alcohol 
better than the Multicore. If you have a fair amount of experience in 
soldering you will not have any problems with the noclean. If you new to all 
of this stick with the Multicore, Kester or Radio Shack rosin core solders 
preferably 63/37. Also don't use silver solder. It is for surface mount parts 
and Elecraft does not have any surface mount, so its not required. It also 
makes rework harder. 

Have Fun
