• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Not sure how up to date the below is but I cut & pasted it from what info I have.
---------------------

FCC Emission Designator Codes

FCC Form 601 requests the emissions of the transmitter. Emissions are designated according to their classification and the necessary bandwidth. Three symbols are used to describe the basic characteristics of radio waves. Emissions are classified and symbolized according to the following characteristics:

* First Symbol - type of modulation of the main carrier.
* Second Symbol - nature of signal(s) modulating the main carrier.
* Third Symbol - type of information to be transmitted.

Whenever the full designation of an emission is necessary, the symbol for that emission shall be preceded by the necessary bandwidth of the emission.

Designator Examples
The new International Telecommunication Union (ITU) emission designators must be used in place of the old designators. The following provides samples of the corresponding new ITU designators for the most commonly used emission designators:

Description Old New
Frequency modulated (FM) voice 20F3 20K0F3E
Frequency modulated (FM) voice 13.6F3 13K6F3E
Frequency modulated digitized voice 20F3Y 20K0F1E
Frequency modulated digitized non-voice 20F9Y 20K0F1D
Amplitude modulated single sideband voice 3A3J 3K00J3E
Amplitude modulated (AM) voice 8A3 8K00A3E

If you have questions about your emission designator, you may want to contact your radio vendor or manufacturer. Also, emission designators should be included in the type acceptance paper work from the Commission. Emissions are discussed in the CFR 47, 2.201 and 90.207.
---------------------------------------------
Emission Designators - First Symbol
Types of Modulation of the Main Carrier:
Description Symbol
Emission of an unmodulated carrier N
Emission in which the main carrier is amplitude-modulated (including cases where sub-carriers are angle-modulated):
Double-sideband A
Single-sideband, full carrier H
Single-sideband, reduced or variable level carrier R
Single-sideband, suppressed carrier J
Independent sidebands B
Vestigial sideband C
Emission in which the main carrier is angle-modulated:
Frequency modulation F
Phase modulation G
Emission in which the main carrier is amplitude and angle-modulated either simultaneously or in a pre-established sequence D

Emission of pulses:*
Sequence of unmodulated pulses P
A sequence of pulses:
Modulated in amplitude K
Modulated in width/duration L
Modulated in position/phase M
In which the carrier is angle-modulated during the period of the pulse Q
Which is a combination of the foregoing or is produced by other means V
Cases not covered above, in which an emission consists of the main carrier modulated, either simultaneously or in pre-established sequence, in a combination of two or more of the following modes: amplitude, angle, pulse
W
Cases not otherwise covered
X
Whenever frequency modulation "F" is indicated, Phase modulation "G" is also acceptable.
* Emissions where the main carrier is directly modulated by a signal which has been coded into quantized form (e.g. pulse code modulation) should be designated under amplitude modulation or angle modulation.
-------------------------------------------
Emission Designators - Second Symbol
Nature of Signal(s) Modulating the Main Carrier:
Description Symbol
No modulating signal 0
A single channel containing quantized or digital information without the use of a modulating sub-carrier, excluding time-division multiplex 1
A single channel containing quantized or digital information with the use of a modulating sub-carrier, excluding time-division multiplex 2
A single channel containing analog information 3
Two or more channels containing quantized or digital information 7
Two or more channels containing analog information 8
Composite system with one or more chan containing quantized or digital information, together with one or more chans containing analog information 9
Cases not otherwise covered X
-------------------------------------------
Emission Designators - Third Symbol
Type of Information to be Transmitted:
Description Symbol
No information transmitted N
Telegraphy - for aural reception A
Telegraphy - for automatic reception B
Facsimile C
Data transmission, telemetry, telecommand D
Telephony (including sound broadcasting) E
Television (video) F
Combination of the above W
Cases not otherwise covered X

------------------

So your 11k3 = 11.3khz wide bandwidth
F9W = see below
*Frequency modulation F
*Composite system with one or more chan containing quantized or digital information, together with one or more chans containing analog information 9
*Combination of the above W
