[Elecraft] Radio Shack Solder ??

[Jack Smith]

Here's how one reference describes the advantage of silver:

    *60/40 and 63/37 Solders*
    These solders are used in the stained glass industry and also for
    electronic component such as computers and communications equipment
    where a minimum of heat can be used to make the connection. For the
    electronics industry, silver is added to tin/lead solders to reduce
    the dissolution of silver from silver alloy coatings. Silver may
    also be added to improve creep resistance.

You may also recall the old Tektronix vacuum tube oscilloscopes built 
with ceramic strips. The notches were metalized with a silver-bearing 
compound and the scopes had a short length of silver bearing solder 
included with each scope. (I think that might have been 4% silver, but 
it's been a long time.)
