One of the potential benefits of the RBN has been the use of our archive for studies of propagation, but a barrier to that has been the difficulty of importing and managing all that data. Now Stephen, WD5EAE has developed a technique for importing some 240 million RBN spots into PostgreSQL. You can read all about it at his web site.
Already doing propagation analysis with RBN data? We'd love to hear about it!
