[Elecraft] [K3] - mods and solder

[David Ferrington, M0XDF]

Well, all this talk of mods got me wondering and I liek some opinions  
from this group - I KNOW some of you know a lot about solder.

Resin core solder - thats not acid flux is it?

Most of my solder came from my time with electronics in defense over  
30 years ago.

I have 2 reels that are labelled:

Ersin non-corrosive flux made by Ersin Multicore Solder and has 362  
Flux, DTD599, BS441, Type 1 written on the label.
This is 18 SWG, .048", 1.2mm (this is a time when you got told every  
which way)

The other roll is only 2 years old, is from RS (that's Radio Spares in  
UK) but made by Multicore and supposedly low temp (melts at 183 C).
It has 'Crystal 400 60/40 Tin/Lead EN29453, S-Sn60Pb40E on it and is  
0.7mm

So I'm guessing that the later would be preferable for use on the K3  
and on my XV144 which I'm about to start.
