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 that multiple different emissions within the specified bandwidth are possible.
This simplifies filling information into the FCC form, but does not for each specific modulation type. For example, 11K2F9W may indicate that the system toggles between narrowband analog voice and P25 or some other digital emission, but not at the same time.
A strict interpretation of ITU emissions indicates that the F9W suffix radio both analog and digital simultaneouslyand is therefore incorrect. A properly completed form should itemize each discrete emission intended so the technologies used may be easily identified.

Formerly and incorrectly used as a catch-all narrowband emission for analog and digital use. Each appropriate emission should be listed discretely.
A "catch-all" designator originally amateur for a number of simultaneous emissions, chart has emission misused as a single designator to fcc multiple types of operation.
