Description
This API provides the data necessary to make a channel report that is used to demonstrate minimum distance separation requirements for FM facilities pursuant to §§ 73.207, 73.215, 73.807 and 73.825 of the FCC Rules.
This API is considered closed data and is only available to those with a specific client relationship with REC to access the APIs.
For demonstration purposes and to encourage development, queries in the state of North Dakota can be ran without subscription and API key.

Parameters
| key | hex(32) | Required except for demo in North Dakota. | API key provided by REC Networks. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| lat | decimal | required | Latitude of the target site. This is NAD83 datum in decimal form. South latitude (American Samoa) is a negative number. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| lon | decimal | required | Longitude of the target site. This is NAD83 datum in decimal form. West longitude (all areas except Guam & CNMI) is a negative number. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| chan | int | required | Channel number to check at target site. (numeric between 200~300). | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| cls | varchar(8) | required |
Service class to check. Valid service classes are as follows:
LP250 is the REC "Simple250" Petition for Rulemaking RM-11909. LP10 is the now-discontinued LPFM service class. C4 is the proposed C4 class of service. |
||||||||||||||||||||||||||||||||||||||||||||||||||||
| notch | int | optional | A FCC facility ID that will not be considered in the search. Only one facility can be notched. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| adjLimit | int | optional |
When used, the channel report result limits the display to certain adjacent channels:
When adj_limit is used, no intermediate frequency results will be returned. If used on Channels 200~220, no TV Channel 6 results will be included. |
||||||||||||||||||||||||||||||||||||||||||||||||||||
| short | char(1) | optional | If Y, the API will only return information on short-spaced faciltiies. Those that meet distance separation requirements will not be returned. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| fullOnly | char(1) | optional | If Y, for radio facilities, the API will only return full-service broadcast stations (including allotments). LPFM, FM translators and FM boosters will be excluded. |
Return
HTTP Code 200
properties
| latitude | decimal | Decimal latitude in NAB83 datum of inquiry. |
| longitude | decimal | Decimal longitude in NAD83 datum of inquiry. |
| channel | int | FM channel number of inquiry. |
| siteClass | varchar(8) |
Station class of inquiry. NOTE: Searches for LP100/LP100PR will return the REC internal service class (LI/LIPR) (letter I, not 1), LP250/LP250PR will return L3/L3PR and LP50/LP50PR will return L2/L2PR. |
| notch | int | Facility ID of notched facility. null if no notch was specified in the API call. |
| report | schema | See report/facility below. |
| facilitiesFound | int | The number of facilties returned in this query. |
report/facility
Within report, the API will return a facility section for each facility. This will be provided in an array. The array key of 0 is not used.
| shortSpaced | char(1) | Y if the facility does not meet §§73.207, 73.215, 73.807 or 73.825 minimum distance separation requirements. Note: when used with channels 200~220 and a full-service class, it will show all stations, including full-service as meeting minimum spacing for purposes of §73.525. This is something we may add in the future but for now, please note the API does not currently support §73.525 minimums to be an "affected station". N if the facility meets §§73.207, 73.215, 73.807 and 73.825 minimum distance separation requirements. |
||||||||||||
| incomingIntf | char(1) |
When used with an LPFM service class: When used with a non-LPFM service class, it will always display N. For TV Channel 6 facilities, it will always return null. |
||||||||||||
| medium | varchar(5) | The medium of communication. This will return either radio or TV. | ||||||||||||
| facilityType | varchar(13) |
The type of facility. This will return one of the following:
|
||||||||||||
| channel/ID | int() | For FM facilities, the channel number beween 200~300. For TV facilities, this will always return 6. |
||||||||||||
| channel/frequency | decimal() | For FM faciltiies, the frequency in megahertz (87.9~107.9). For TV facilities, this will always return 82. |
||||||||||||
| channel/adjacency | varchar(14) |
For FM faciltiies, this will return the adjacency relationship of the channel:
For TV facilities, this will always return ChannelSix. |
||||||||||||
| class | varchar(2) |
For radio stations, this will return the station class. LP100 stations will show with class L1. FM Translators and FM Booster stations will return null. For TV stations, this will return:

| distance/margin | decimal | Actual distance minus the required distance in kilometers. If this value is -0.5 or less, the facility is short-spaced. | ||||||||||||
| bearing | decimal | The bearing/heading in degrees from the target to the facility (0.0 through 359.9 degrees). | ||||||||||||
| applicationId | hex(32) | The application ID from the FCC's Licensing Management System. | ||||||||||||
| party | varchar(80) | Name of the licensee or applicant from the eLMS facility records. | ||||||||||||
| readingService | char(1) | Y indicates that this facility was identified in the past as carrying a radio reading service for the blind. LPFM applicants may be required to provide protection on third-adjacent channels, pursuant to §73.807(a)(2). | ||||||||||||
| superPower | array | This item appears alone with a value of null in the case of FM facilities in the non-reserved band (Channels 221~300, 92.1~107.9 MHz) or Channel 6 TV stations. | ||||||||||||
| superPower/isSuper | char(1) | Y indicates that this facility, which is in the reserved band (Channels 201~220, 88.1~91.9 MHz) is operating a service contour in excess of its service class on a grandfathered basis.

| superPower/protectedAt | varchar(2) | If the value of superPower/isSuper is Y, this value is the service class that an LPFM station would have to protect this facility. For LPFM classes of service as the target, the value of distance/required and distance/noInterference will reflect the distances at this service class. | ||||||||||||
| facComments | varchar(1000) | Facility comments from CDBS. These normally only appear on FM records and mainly for facilities located near an international border as they give information about the international coordination. LMS does not have a similar function. If there are no comments, this section will appear as an empty string (""). | ||||||||||||
| appPurpose | varchar(4) | Application Purpose Code from eLMS. | ||||||||||||
| appStatus | varchar(3) | Application Status Code from eLMS. | ||||||||||||

Rate Limiting
The general rate limit for unauthenticated accesses across all REC APIs is 20 calls per minute (one call every 3 seconds). Calls to other REC non-API services subject to rate limiting also contribute to this count. These other services may have lower rate limits. For authenticated users, the rate limit will be based on negotiations with REC Networks for API access.
