What emission designation is H3E?
The Emissions Designator —-H3E– signifies a wireless radio which transfers data over a modulated wave using Single analog channel signal. This signal transmits Unknown or undescribed signal details at a Unknown [—-] maximum bandwidth using Unknown, Other, or No Multiplexing Used.
What is A9W?
The Emissions Designator —-A9W– signifies a wireless radio which transfers data over a modulated wave using Composite, one or more digital channel, one or more analog signal. Emissions Designators describe the type of signal only.
In which ITU publication are the classes of radio emission found?
Related Documents Recommendation ITU-R SM . 1138: Determination of necessary bandwidths including examples for their calculation and associated examples for the designation of emission.
What is emission code?
An emission designation is of the form BBBB 123 45, where BBBB is the bandwidth of the signal, 1 is a letter indicating the type of modulation used of the main carrier (not including any subcarriers which is why FM stereo is F8E and not D8E), 2 is a digit representing the type of modulating signal again of the main …
What is an emission designator on a scanner?
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.
What is an emissions designator (Edd)?
An emissions designator is a 6 to 8 character code identifying the electromagnetic modulation characteristics of a wireless device. Different codes represent different features of the wireless emissions from a product.
What does the 6th character of an emission designator mean?
The 6th character of the emission designator (2nd character in legacy designators) signifies what type of data is being transmitted. Identified data transmission types are below: B – Telegraphy for machine copy (RTTY, fast Morse) The 7th and 8th characters of emission designators give optional detail on the signal and datatype being broadcasted.
What does 11k2f9w mean in FCC 601 form?
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.
