Errors on

Every so often, we receive a phone call or e-mail in regards to the content at  Sometimes, people think we run the TV station and they will complain about something they saw or bad reception, etc.  We also get contacted by stations and listeners to correct information on the site.  Much of the content on is generated by the various government regulators.  REC, the operator of FCCdata mines this data and presents it on the website in a manner whcih we hope you find easier to understand.  

Please note that for FCC broadcast data, we have been experiencing a ton of database issues since FM radio was converted from CDBS to LMS.  This includes previous records still showing as current, incorrect facilty parameters (especially on LPFM stations), incorrect or missing contour maps, etc.  REC has a dialogue with the FCC Media Bureau to address these issues to benefit all public users of the raw data.  This is something we can't change here.

Before contacting REC regarding something you see on, here are some of the most frequent inquiries and what to do specific to each country:

United States

Station specific data originates from the FCC.  REC receives feeds from their CDBS database (for radio) 5 days per week and from LMS (for television) 7 days per week.  For amateur radio, we receive updates from the FCC's ULS system 5 days per week.  Some data such as antenna structure registration data, broadcast auxiliary/remote pickup and International Bureau data is obtained periodically following no set schedule.

Incorrect owner or mailing address - The information at the top of the screen comes directly from the FCC's CDBS facility tables.  Shortwave stations come from IBFS.  If the information is wrong but you have filed a change of address in CDBS or have filed a subsequent application, it is very possible that the FCC never updated the facility file.  I am not sure how that is done internally so you will need to contact the Media Bureau at the FCC is this information is still incorrect, despite the changes you had already filed.

Recent application filed not showing up - While we expect the FCC to provide a new CDBS raw data file for us to pick up and process every business morning, sometimes they don't.  We have sometimes gone for about a week without a data update.  There is nothing we can do about that.  REC will post on our Facebook page if there is a delay in data.  But in the long run, this is an FCC issue.

The format or slogan of the station has changed - Except in Japan, REC does not track slogans or monikers for stations.  Also, we do not track entertainment format.  

The logo graphic that shows for the station is incorrect - REC pulls this data directly from FCC's Public File system and does so in real time.  If your station's logo is incorrect on, please access the FCC's Public File system and upload a new logo.  Due to cached browsers, it may take time before the new logo is visible on all browsers.

Translator not rebroadcasting the station shown on FCCdata - Normally, this gets changed if the primary station is defined on Forms 349 or 350.  If the translator licensee notifies the FCC directly about a primary station change, it may not always reflect. 

ERP and/or HAAT on mainly LPFM records showing in scientific notation (e.g. 7E-8, etc.) - This is a known issue with LMS.  The FCC is aware of this.  We have no way to change this.  This may also reflect in contour maps.

Contour map is not accurate - Review the text under the contour map.  If the contour map shows "based on REC estimate", then we own -  it and you can refer any issues to us.  In the e-mail, please make sure you copy and paste the URL in the address bar of your browser so we can recreate the problem.  If the contour map shows "Based on FCC data", then you are seeing a contour generated by the FCC and then sent to us on a daily raw data file.  We do recognize that some of those contours are not rendering correctly.  The most you can do is contact the CDBS Help Desk for assistance.  FCC AM stations: The contour maps were generated from an FCC API.  We are aware that some records are not showing correctly and that is based on data provided by the FCC.  The data provided by the FCC is for information only and is not legally binding.  

Can you contact the owner of the station for us? - The only information we have is what you see in  Virtually all station records have a phone number.

A station you show does not exist - If that station is silent for more than 10 days, then the station is required to contact the FCC to advise of being silent and if they intend to be silent for more than 30 days, they need to file a special temporary authority. 


REC receives a weekly feed from Industry Canada.  It's not perfect but it does work.  

The database shows a Canadian station as a Class A when it really should be a A1 - Look near the top of the page to see which tab is highlighted in yellow:

  • USA (AM/FM/TV) - You are looking at data from the US FCC.  The foreign data in the FCC database is based on service classes recognized under international agreement.  Even though Industry Canada may have assigned the station with a Class A1 facility, they may have negotiated a Class A facility with the United States.  Clicking the Canada tab and re-searching would be your best bet.
  • Canada - This information is completely managed by Industry Canada.  You will need to contact them.

The address, call sign, location, etc. is incorrect - A representative of the station should contact Industry Canada for assistance. 


Mexico data is manually researched from the online files of the IFT.  When Mexico grants a concession (license), it grants it for a community/market and documents reflect that.  In other words, we do not always receive the technical information for the facility.  If a technical modification for the facility has taken place recently, then the letter written by the IFT granting the modification will include more technical information.  With the recent conversion from analog to digital television as well as the overall transition of many AM stations to FM, we are seeing more TV and FM records with technical details, however, many older (traditionally FM) stations may not have these details and until there is a time when the IFT releases more technical data, we will never have it.   For AM facilities, we are using the internationally reported geographic coordinates for location and the IFT concession letters to determine operating power.

As of November 6, 2018, we are slowly building up Mexican data into starting north and working south.  

Once entered, this data will be under the full control of REC however we do not know yet what kind of updating schedule will be put in place.  We feel that this data will rarely change.


REC receives a spreadsheet from ComReg which is then parsed and loaded into the database.  This spreadsheet only shows RTE stations and has not been updated since 2015.  The BAI does not make similar information available about private stations.  More information about Irish radio should be available at the BAI's website.  REC will not add any stations nor will we correct any RTE stations.  A complaint may get us to check with ComReg to see if a new file is available, but that's about it. 

United Kingdom

Like with Ireland, REC receives a spreadsheet from Ofcom that has the technical information that can then be parsed into the database.  Unlike Ireland, BBC and private stations are in the spreadsheet.  REC will not add or correct any of the stations.  Ofcom should do that and make a new file available for us. 


Australia's data is received daily from the Australia Communications and Media Authority (ACMA).  This is a completely automated process.  If there is an issue with incorrect data on Australian facilities, someone reponsible for the broadcast facility should contact the ACMA.   REC can not make any manual fixes to ACMA data on our site.


Japan's data on FCCdata is completely under REC's control.  Information is normally updated about once every 3 to 6 months as time permits between other projects and work.  We may not be able to catch every time there is a slogan change even though unlike US radio, this does not happen very often in Japanese radio.  If you notice any changes that we have not caught up with, feel free to contact REC.  Please provide the call sign and the changed information.  If possible, please provide both the romaji (English letters) and the kana (Japanese characters) for any names.  Please correspond with REC in English if possible.   Also, for new or changed facilities, if you have a link to the license record and/or the information about the change at the MIC website, please also provide those links. 

It's also important to realize that MIC (Japan's FCC) does not release directional pattern tabulations for any station.  Therefore, the maps in FCCdata and Denpahoso assume a non-directional facility.  We have no way of changing that it this time.  

If you have a situation above that qualifies for handling by REC or you are reporting some kind of website functional issue that affects more than one facility in the same country, please use our Contact REC form to let us know about it!

Thank you for using!
