Fields

Application Type

Indicates if the current record represents new information or modifications to Industry Canada's information about your existing systems. (Note that you cannot update this selection once you save the record.)

Record ID.

Filters Active on Authorized Frequency Record (Tx)

For modified frequencies only, the number of filters that were associated with the original frequency record as authorized. Because we don't provide a facility for editing your filter records, this number is provided to remind you whether you have filter records. The number represents the total of all filters on the Tx line (includes Tx/Rx filters).

For modified frequencies, have you made changes...? (Tx)

For modified frequencies, indicates whether you have made any changes to your existing filters. If you answer "No", we will keep your existing Tx filter records and add any new filters in your application. If you answer "Yes", we will remove existing filter records and replace them with any filter records in your application.
