Processing utilities enable users to perform checks prior to filing certain applications.
AM Tower Locator
The AM Tower Locator is a tool that allows you to determine whether the construction of a proposed tower requires you to notify AM stations prior to construction. This notification process is required by FCC rules.
Check to see if you are within the glide slope (if you fail you may be required to register your structure)
Channel 4 & 5
The Proximity to TV Channels 4 and 5 program returns any Channel 4 or 5 station that does not meet the 80-mile separation distance.
Rule Section 90.257 states that all Part 90 authorizations (e.g., private land mobile radio services) in the 72 – 76 MHz band may not cause harmful interference to television reception on Channels 4 or 5. The Private Wireless Division maintains a database of Channel 4 and 5 television stations.
The Congested Area Program identifies congested areas.
When you submit a latitude and longitude, the program will produce a table of congested areas where the entered coordinates reside. Rule 101.115, which replaced Rule 94.75(b), provides for two categories of antenna standards. You must use Category A antennas in congested areas as defined in the 1976 Public Notice.
The Distance Check program calculates the distance between two entered coordinates by using the criteria found in Rule Section 73.208(c).
Market Cross Reference
The search enables a user to search by Major Trading Area (MTA), Basic Trading Area (BTA) or state and county to find the corresponding markets. The market identifiers are MTAs, BTAs and counties.
Geographic coordinates provided to the Commission via the Universal Licensing System must be referenced to the North American Datum of 1983 (NAD83). If the source from which you obtain the coordinates is referenced to another datum (e.g., NAD27, PRD40) you must convert the coordinates to NAD83.
The FCC uses the procedures outlined below when converting licensing data to NAD83 coordinates when a radio service is converted to the Universal Licensing System (ULS). In most cases, this procedure uses the NADCON software developed by the National Geological Survey. For certain Pacific island areas, the FCC uses a specified shift from the applicable local datum. For other Pacific island areas where a conversion is not yet available, coordinates should continue to be referenced to the applicable local datum.
United States Borders /Regions
The US Borders program determines the distance to the Canadian and Mexican borders and determines what region the user-specified coordinates reside as defined in Rule Section 90.619. Rule Section 90.619 defines Canadian regions for 800 and 900 MHz land mobile radio stations. This rule also defines which frequencies may or may not be assigned in regions near the Canadian and Mexican borders.
This program provides you the distance to Chicago. Rule 90.617 defines a unique channel plan for the Chicago area that the FCC defines as stations with a 70-mile radius of 41º 52′ 28″N and 87º 38′ 22″W.
This program alerts you if the entered coordinates are in proximity to a defined peak as defined in Rule Section 90.621. Rule section 90.621 defines mountain peaks that should be provided special protection criteria.
Line A and Line C
The Line A and Line C Program determines whether an entered coordinate is SOUTH of Line A or WEST of Line C. Line A is an imaginary line within the US, approximately paralleling the US-Canadian border. To the north of Line A, FCC coordination with Canadian authorities is generally required in the assignment of frequencies.
Line C is an imaginary line in Alaska approximately paralleling the Alaskan-Canadian border. To the east of Line C, FCC coordination with Canadian authorities is generally required in the assignment of frequencies.
Population 200k and 600k
The Population program provides access to the population 200k and 600k databases.
The program uses these databases to list cities with 200,000 people within 75 miles of the entered coordinates. The program also lists the cities with 600,000 people within 87 miles of the entered coordinates.
The program verifies compliance with Rule Sections 90.261, 90.20, 90.17, 90.35, 90.63, 90.65, 90.67, 90.73, 90.75, 90.79, and 90.93.
