So it was somewhat of a challenge, but I finally got this up and running. It was bought from Amazon in ~October of last year.
Right out of the box, I did notice something interesting: it appears that event log entries during testing of the unit were still present, as shown below:

It appears this testing was done primarily on July 16, 2014, according to the dates in the log.
Anyone else see this?
EDIT added spectrum graph
