Search Criteria

Enter the search parameters for the Geographical Area Search. You must complete all fields to conduct the search. Click the Find button to start the search, or select fields and use the Find button at the bottom of the page.

When defining the search area, the Geographical Area Search engine determines the centre point for the search by using the latitude and longitude values entered in the search coordinates. It then uses the Search Radius value to create a square box whose sides are each one radius north, south, east, and west of the centre point.

Fields

Frequency Range (MHz): Lower

Enter the lower range of the frequency band in which you wish to search. A valid frequency value is in the range of 0.000001 to 999999.999999 MHz.

Frequency Range (MHz): Upper

Enter the upper range of the frequency band in which you wish to search. A valid frequency value is in the range of 0.000001 to 999999.999999 MHz.

Frequency Type

Select whether the search should match transmitter (Tx) frequencies, receiver (Rx) frequencies, or both (Tx or Rx).

Centre of Search Area: Latitude

Enter the latitude of the centre point of the search area. The format is "ddmmss", where dd is degrees north in the range 40 - 89, mm is minutes in the range 0 - 59, and ss is seconds in the range 0 - 59.

Centre of Search Area: Longitude

Enter the longitude of the centre point of the search area. The correct format is "(d)ddmmss", where ddd is degrees west in the range 46 - 149, mm is minutes in the range 0 - 59, and ss is seconds in the range 0 - 59.

Search Radius (km)

Enter the search radius for the search area, in km. The starting point of the radius will be determined by the Latitude and Longitude coordinates entered above.

Station Type

Select a radio button to specify the type of station to search for. Search results will not necessarily include wide area operations. For example, Ontario Hydro Services is licensed to operate anywhere in Ontario, and thus is not included in search results. Otherwise, they would appear in any search results that included Ontario. Options are Fixed, Mobile, Broadcasting, or All Types. Searches that include mobile-to-mobile stations will return radius of operation.

Output Format

Select the format for the search results:

• HTML with selected fields for viewing online or printing using your web browser.
• ASCII with selected fields for downloading.
• ASCII with all fields for downloading.
• XML with all fields for downloading.

If you select an option with all fields, use the adjacent drop-down list to select whether to include filter or link station fields (you cannot include both).
