24-Oct-2009 Added Industry Canada TV Database |
|
In the past, information about Canadian transmitters was provided through the FCC database. Through a cooperative data sharing agreement, the US and Canada shared transmitter data so that each government could work out their frequency plans and minimize interference on both sides of the border. Unfortunately, this data gets outdated quickly and the FCC has not done a good job of keeping the Canadian transmitter records up to date in their database. It has been pointed out several times in the past that Industry Canada maintains a more up-to-date database of those transmitters. Starting today, we now use the Industry Canada database to represent Canadian transmitters. This will hopefully correct some of the FCC errors that have been observed in the past (like transmitters at the wrong location, ones that are not on the air, or transmitters with incorrect channel assignments). This is still no guarantee that all the records will be accurate, but we hope this is a step in the right direction. If anyone notices any entries that need to be fixed, please let us know via the "contact us" button at the top of the page. |

30-Aug-2009 Updated Google Earth Coverage Maps |
We're pleased to announce the availability of updated Google Earth coverage maps! These maps are similar to ones available before, but have been updated as follows:- Updated to latest snapshot of FCC database.
- Both current and pending sets are available. This is based on a snapshot of the FCC database plus any pending applications that have been published.
The list of available metros and their download links are available in the Coverage Maps section. |

19-Jul-2009 Change to reporting options |
|
Now that the June 12th analog shutdown has come and gone, there's not much sense in looking at current and post-transition reports in the Signal Analysis Tool. So as of today, the report output will take on a slightly different meaning. The report output will now include an analysis for "current" transmitters as well as "current + pending" transmitters. This latter option will include any pending applications on file with the FCC. The new "current + pending" analysis will let you see the effects of transmitter changes that are still "in the pipeline". This includes things like power maximization requests, channel change requests, translator/booster updates, and technologies on the horizon (e.g., Distributed Transmission Networks, ATSC Mobile/Handheld, etc.). If a local broadcaster has requested a change to improve their coverage, here's a way for you to peek into the future to see how those changes might affect you. Please keep in mind that the analysis of pending applications is purely speculative. Until the FCC actually processes these applications and either grants, modifies, or rejects them, there's no guarantee that these changes will be allowed. If the FCC grants any of these requests, they will eventually become part of the main database and show up in the analysis for "current" stations. The reporting changes can be seen in both the "radar plot" Signal Analysis Tool as well as the "interactive" TV Maps tool. |

7-Jul-2009 Rollback of some records in FCC data |
|
Since the FCC has recently started adding many new records to their database, many transmitters were showing up in the TV Fool analysis results even though they are not on the air yet. Many of these FCC applications will presumably begin operation over the next few months, but including them in the reports now just creates a lot of confusion. For the moment, we've decided to back off from these latest database records and try to only include records that are currently operational (to the best of our knowledge) rather than project what transmitters might be online sometime in the future. As always, if you notice any errors in the active database, just let us know and we'll be happy to correct them. Coverage overlays are currently being processed offline and will take several days to finish. If you notice any missing or incorrect coverage overlays, please be patient while we process the map updates. Due to the processing time required for overlay generation, they will always lag behind the live database by a bit. The online signal analysis tools will reflect the latest database changes immediately. |
