[Elecraft] No clean solder

[moe at ecosse.net]

Hi Bob

Thanks.

I just want to make sure it doesn't give trouble later.

I am using crystal400 halide free.

Actually , I was using crystal 511  multicore for various things and seems to 
be OK.

Just I want my K2 to last all my life or may be most of my life.
