Andrew,

The Tier 2 servers that have been configured for experimental SSL
identify with certificates signed by a custom Tier 2 Certificate
Authority. For client verification, they check that certificates are
signed by ARRL LotW.

Here is the Tier 2 CA root certificate, also available by exporting
from your browser as Curt described:

P.S. Please make sure your application allows, and can be configured
to request, eNULL cipher. This allows SSL authentication without
encryption, so it is legal for use over Part 97. In our area, some
igates connect over Part 97 wifi links. If the client does not request
eNULL cipher, aprsc will default to using encryption over SSL links.
