If you have ever obtained a license from the FCC or spent anytime looking at your radios manual you will notice a seven digit code. Like 11K2F3E or 20K0F3E. Its not there for decoration, it actually means something. The first four digits, in the example above, stand for occupied bandwidth in kilohertz.

Guide to Emission Designators An emission designator utilizes a seven-character “word” to represent the bandwidth, modulation, nature of signal, and type of information transmitted by a particular radio. The emission designator is required in most FCC radio applications. The International Telecommunication Union uses an internationally agreed system for classifying radio frequency signals. Each type of radio emission is classified according to its bandwidth, method of modulation, nature of the modulating signal, and type of information transmitted on the carrier academiy-malig.info is based on characteristics of the signal, not on the transmitter used.
