Re: [Elecraft] high altitude solder
I need to trot right up to NASA up the street and ask to trade my recently acquired 50 rolls of Kester 44 for some of that HAHA, I saw these messages about high altitude solder last night and never heard of anything so dumb!

Re: [Elecraft] High Altitude Solder
Looks like the arts and crafts folks have dealt with this issue before - http://www.ganoksin.com/orchid/archive/199912/threads.htm I did not read much of the thread, but it looks like you have to immerse the radio in Nitrous Oxide while soldering. They also suggest using a lot of hot air instead of directly contacting the joint with a hot iron tip.

I use the fresh water variety, since I do most of my mountain topping on inland mountains. I get it from Cousteau Electronics Supply, they are on the web. You do have to be careful when you go up the mountain. If you go too fast, the point to point wiring gets the bends and that plays havoc with the efficiency. By the way, you can still use your rig in your ham shack if you immerse it in distilled water, overnight. This treatment keeps the solder active for about a week.

Re: [Elecraft] High Altitude Solder
Does anybody know of a vendor that still sells it? Are there any special precautions or procedures for using this solder? Any quality solder will work. You just have to assemble the K-1 in a vacuum chamber to out-gas the connections. Remember to hold your breath to avoid contamination. Actually, it is OK to not hold you breath. The secret is to not exhale...

RE: [Elecraft] High Altitude Solder
I was impressed with the added performance from using HA solder on my K1 SN 1976 at altitude, but I thought the advantages were quickly lost from having to store the K1 in an altitude chamber when I got home. I'm not seeing the full 22% increase that some are seeing since the mountains around here are limited to around 11,000+'. I built my chamber from an old Pelican case and a C&H dry vane vacuum pump. I stick a pocket altimeter inside to monitor "vacuum" and maintain it at the 18,000' specified for HA solder in long-term storage. I have a quick disconnect fitting so I can unplug the Pelican case from the pump and it maintains "altitude" long enough for me to get back to the mountains. Details on my web site.

RE: [Elecraft] High Altitude Solder
Lynn, The best is liquid solder - one used to find it in hardware stores, but I havn't looked recently. Those loose electrons are the main thing that improves the efficiency. Now if someone could just come up with a way to keep it from hardening so the electrons stay loose longer . 73, Don W3FPR > -Original Message- > > I plan to do a lot of mountaintopping in the next few years and will > be assembling a K1 for this specific use.
