Folks,
There are many different FCC Databases out there.
RP licenses are actually kept in the database entitled "Land Mobile - Broadcast Auxiliary"
AF licenses are in the "Martime Coast and Aviation Ground" database
We are only loading the "Land Mobile - Private" licenses at this, since this database contains all of the licenses for Public Safety uses and most standard business issued licenses today.
Another database is the Land Mobile Commercial database which mainly has industrial and business SMR type licenses (read: millions of Nextel licenses).
Believe it or not, the fcc databases are very complex and VERY large. I am working on a solution to eventually load all of the databases, however providing the level of reporting that we do (PDF downloads for a county, all licenses in a county etc) are very challenging and costly queries which take a lot of performance from the database to execute in a reasonable manner. For instance, the most popular reports that people use are the Last FCC grants in a county and all FCC licenses in a county.
Remember, Gullfoss and the FCC servers are not providing these types of reports - but we are able to do it on-demand. The FCC really only provides some simple searches like by callsign etc.
We are getting there, but keep in mind that for me to deploy the same functionality that we have today with all of the FCC databases that are potentially relevant to us, will require me to invest in a high-end database server to execute the queries in the timeframes that everyone will want (near instant) ;-) I am planning on doing this...
