[Elecraft] No clean solder

[Bob Nielsen]

Hi Moe,

In my search for information on X39 flux, I found (via Google) some  
information from Rapid Electronics which also descripes Crystal 400  
and 511.  It doesn't appear that there should be any problems with  
either of these.

I tried to send you the data directly as an attachment, but was  
unable to do so.  You can download it from <ftp://n7xy.net/solder.pdf>.
