How are FCC call signs assigned?
A unique call sign is assigned to each amateur station during the processing of its license applications. Each new call sign is assigned sequentially using the sequential call sign system, which is based on the alphabetized regional-group list for the licensee’s operator class and mailing address.
Why do some TV stations have 3 call letters?
The three letters after the ‘K’ or ‘W’ can mean a few different things. Sometimes they represent the networks that own the radio station—for example, WABC, KCBS, and WTBS. Sometimes it’s the actual station number, like in KTWO or KFOR.
What are TV call signs?
Broadcast call signs are call signs assigned as unique identifiers to radio stations and television stations. While broadcast radio stations will often brand themselves with plain-text names, identities such as “cool FM”, “rock 105” or “the ABC network” are not globally unique.
What does K and W stand for?
In 1937, the initials K&W (for Knight and Wilson) were adopted and K&W Restaurant was established. Allred later acquired a one-third interest in the K&W Restaurant.
How do I choose a callsign?
When choosing a callsign you need to consider the group in which they fall into. There are four groups based on authorized license class. These groups determine the number of prefix and suffix letters. After earning your first technician license, most hams receive a 2×3 callsign.
What is a 2×2 callsign?
I found out a while back that, as things currently stand with the FCC, if you take and pass all three license class exams in the same sitting, you get a so-called “two by two” or 2×2 call — two letter prefix, region/district number, and two letter suffix.
Why do some stations start with K?
Following a practice inaugurated in 1912 when the federal government first licensed radio stations, beginning in 1921 broadcasting stations have generally been assigned call signs beginning with “K” when their community of license is located in the west, and with “W” in the east.
Why do US radio stations start with W?
Under international agreement, since 1927 the alphabet has been divided among nations for basic call sign use. The United States, for example, is assigned three letters–N,K, and W– to serve as initial call letters for the exclusive use of its radio stations.

Call signs in the United States are identifiers assigned to radio and television stations, which are issued by the Federal Communications Commission (FCC) and, in the case of most government stations, the National Telecommunications and Information Administration (NTIA).
Why do radio stations end in odd numbers?
Because each channel is 0.2 MHz wide, the center frequencies of adjacent channels differ by 0.2 MHz. Because the lowest channel is centered on 87.9 MHz, the tenths digit (in MHz) of the center frequency of any FM station in the United States is always an odd number.
Why do radio stations have 4 letters?
Most of the first broadcasting stations received randomly assigned three-letter call signs. However, in early 1922, due to the prospect of all the available three-letter call signs being used up, the government switched to four-letter calls that were sequentially assigned.
Why do radio stations have to identify themselves?
The *reason* for requiring identification, at least in most jurisdictions, is so that if a listener hears something they believe breaches the local broadcasting standards (or more egregiously, the law) they know which station it was that broadcast it.
