Experimental CDBS database differ

This directory contains daily reports showing the changes in broadcast facilities from the FCC's nightly exports of the Common Database System. If no changes have been made, the report will be identical to the previous report.

The following are known limitations:

• Distributed Transmission Systems are not implemented (only the first DTS site is shown).
• Not all engineering data is shown. In particular, details relevant to directional antennas (both AM and FM/TV) are omitted at least in part, in order to keep the report readable.
• Not all coded data fields are interpreted (mostly because the FCC doesn't document them all).
• New amendments to existing applications are treated as completely new applications rather than being compared with the application being amended.
• Changes can be missed when the FCC alters the structure of the database exports, which they normally do in a way that breaks reimport of the data by changing the ordering of the fields in the export.
