Fcc emission designators chart for amateur radio

Amateur Radio Tools - Icom America

An emission designator is a code associated with a frequency that gives information about the frequency's bandwidth and the nature of the signal on the frequency. Some license application preparers have used the suffix F9W to indicate emission multiple different emissions within the specified bandwidth are possible. This simplifies filling information into the FCC form, but does not reflect each specific modulation type.

For example, 11K2F9W may indicate radio the system toggles between narrowband analog voice and P25 or some other digital emission, but not at the same time.

Types of radio emissions

A strict interpretation of ITU emissions indicates that the F9W suffix is both analog and digital simultaneouslyand is therefore incorrect. A properly completed amateur should itemize each discrete emission intended so chart technologies used may be easily identified.

Formerly and incorrectly used as a catch-all narrowband emission for analog and digital use. Designators appropriate emission should be listed discretely. A "catch-all" designator originally intended for a number of simultaneous emissions, but has been misused as a single designator to indicate multiple types of operation. Copyright by RadioReference.
