Emissions Designator 16F9Y
Decode the occupied bandwidth, modulation, signal nature, and information type.
Decoded Emission Designator
| Emission Designator | 16F9Y |
|---|---|
| Normalized Code | 16F9Y |
| Necessary Bandwidth | Unknown |
| Modulation Type | [Y] Unknown or other modulation |
| Signal Nature | [-] Unknown or other signal nature |
| Information Type | [-] Unknown or other information type |
What This Means
16F9Y is an FCC emission designator. This short form does not include a necessary bandwidth prefix, so it only describes the emission class: unknown or other modulation, unknown or other signal nature, carrying unknown or other information type.
How to Read 16F9Y
| Step | Value | Meaning |
|---|---|---|
| Bandwidth prefix | Not supplied | Unknown |
| First symbol | Y | Unknown or other modulation |
| Second symbol | - | Unknown or other signal nature |
| Third symbol | - | Unknown or other information type |
Purpose on FCC Records
Emission designators are used on FCC grants and equipment authorization records to summarize the radio emission being authorized. They help identify how wide the emission is, how the carrier is modulated, whether the signal is analog or digital, and what kind of information is being transmitted.
They are useful for comparing radios, matching a grant to a modulation type, and understanding whether an authorization covers voice, data, telemetry, video, or mixed services.
An emission designator is not the whole authorization. It does not by itself prove the exact channel plan, antenna limits, output power, or every condition on the grant. For those details, read the FCC grant and the related test reports.
Bandwidth Notes
The bandwidth prefix uses a letter as both the decimal point and the unit. For example, 20K0 means 20.0 kHz, 8M91 means 8.91 MHz, and 345K means 345 kHz.
Symbol Reference for 16F9Y
| Symbol | Position | Category | Decoded Meaning |
|---|---|---|---|
| Y | First symbol | Carrier modulation | Unknown or other modulation |
| - | Second symbol | Modulating signal | Unknown or other signal nature |
| - | Third symbol | Information transmitted | Unknown or other information type |
Regulatory Reference
The FCC classification system for emission, modulation, and transmission characteristics is defined in 47 CFR 2.201. The FCC also indicates that the full emission designation is preceded by the necessary bandwidth when the full designation is required.
FCC 2.201 Notes
- FCC emission designators combine emission classification with the necessary bandwidth of the emission.
- The three required symbols identify carrier modulation, nature of the modulating signal, and type of information transmitted.
- Fourth and fifth symbols may be added for a more complete description, but the Commission does not require them.
- When frequency modulation F is indicated, phase modulation G is also acceptable under the FCC note in this section.
- Pulse-code or other quantized direct modulation should be classified under the amplitude or angle modulation groups, not merely as pulse emission.
- The information symbol does not include constant, unvarying information such as standard frequency emissions, continuous wave emissions, or pulse radars.
- Type B damped-wave emission is an FCC exception and is forbidden.
- When the full designation is needed, the emission symbol is preceded by the necessary bandwidth as indicated in 47 CFR 2.202(b)(1).
