[Elecraft] high altitude solder

[Jeremiah McCarthy]

Kester 44HA will be available at any NASA facility commissary in the near future...The crew returning from the space station this week brought back 5,000 1 pound rolls that were taken up there in order to out-gas them for high altitude use...Prices will be high...

>I plan to do a lot of mountaintopping in the next few years and will
be assembling a K1 for this specific use. I need to locate a good
source for MILSPEC high altitude solder that meets Elecraft's
specifications and will not void the warranty. The reported 22%
increase in equipment efficiency will make the extra expense
worthwhile. Does anybody know of a vendor that still sells it? Are
there any special precautions or procedures for using this solder?<
