Emission Designator

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.

For scanner users, it can be useful for determining whether a frequency is analog or digital, and even whether the frequency transmits voice and/or data.

* When used between 136 - 470 MHz in Part 90 use, this technology is not compliant with 2013 narrowbanding requirements and must be discontinued by January 1, 2013. As of January 1, 2011, this emission may no longer be applied for between 136 - 470 MHz in Part 90 use, unless it fits within the existing contours of an already licensed system. These emissions may not appear on a new license or be used to extend the footprint of an already licensed wideband system beyond what existed prior to January 1, 2011.

VHF Low Band has not been required to narrowband. A 20K0 emission bandwidth continues to be acceptable for nearly all uses.

Note that an emission designator identifies the characteristics of the signal and is not unique to only one type of technology or manufacturer. More than one type of deployed technology may use the same emission designator.

An editor of this wiki cautions that this guide should not be used by any party as the sole means to qualify or disqualify a license application. THERE IS NO "RIGHT" OR "OFFICIAL" EMISSION DESIGNATOR SPECIFIED BY THE FCC. The reader should not construe that because it's not on this list that it is wrong. This wiki is a reference document, not a directing document.

Use of F9W Suffix

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 601 form, but does not reflect 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 is both analog and digital simultaneously, and is therefore incorrect. A properly completed 601 form should itemize each discrete emission intended so the technologies used may be easily identified.

The exception to using F9W is Harris OpenSky, which has been certificated by the FCC as F9W, although F7W may be better descriptive.
