It seems you're asking about "text, character, what is radio station about options." This can be interpreted in a few ways, so let's break down the common aspects of text and characters related to radio stations:

### 1. Radio Station Call Signs and Branding

* **Call Signs:** Every licensed radio station has a unique alphanumeric **call sign**. In the United States, these generally start with "K" (west of the Mississippi River) or "W" (east of the Mississippi). These are legally mandated identifiers (e.g., KEXP, WNYC). They typically consist of 3 to 9 letters and digits, with commercial stations often having four letters (e.g., KSL, WGN).

* **Branding/Slogans:** While call signs are official, most stations also use more memorable and descriptive **plain-text names or slogans** for branding. This is what listeners typically associate with the station (e.g., "The Beat," "Power 99," "NewsRadio 880"). These are not globally unique, but are often localized.

* **Station Identification:** Stations are required to identify themselves periodically with their call letters and community of license.

### 2. Text Features in Radio Broadcasts (RDS)

* **Radio Data System (RDS):** This is a technology used in FM radio broadcasts to transmit small amounts of digital information alongside the audio. This "text" information can include:

    * **Program Service (PS) Name:** An eight-character static display that typically shows the station's call letters or identity name (e.g., "KISS FM", "BBC R4").

    * **Radio Text (RT):** A free-form text message (up to 64 characters) that can be static (like station slogans) or dynamic (like the title and artist of the currently playing song). Some receivers support RT+ which allows for more structured data like song titles and artists to be extracted and displayed separately.

    * **Program Type (PTY):** A code that categorizes the type of program being broadcast (e.g., "News," "Sport," "Pop Music," "Talk"). This allows receivers to filter by genre.

    * **Traffic Announcement (TA):** A flag indicating that the station is currently broadcasting a traffic report, allowing compatible radios to automatically switch to that station.

    * **Alternative Frequencies (AF):** A list of frequencies for the same station, allowing car stereos to automatically re-tune to the strongest signal as you drive.

### 3. Text and Character Usage for Listener Engagement

Radio stations extensively use text messaging (SMS) to interact with their audience. This falls under the "options" for how text and characters are used:

* **Contests and Giveaways:** Listeners text in keywords to enter contests.

* **Listener Requests/Feedback:** People can text in song requests, comments, or questions to talk shows.

* **Promotions and Advertisements:** Stations send out offers, discounts, or event invitations to their text message subscribers.

* **Emergency Alerts:** Broadcasters can send out critical information like weather warnings.

* **Polls and Surveys:** Engaging listeners by having them text their responses to questions.

* **Building Listener Lists:** Encouraging listeners to subscribe to their SMS updates using keywords.

* **Direct Communication:** Two-way texting allows for more personalized conversations with listeners.

### 4. "Radio Character" in Storytelling

If by "character" you mean a **fictional persona**, then in radio, a "radio character" refers to a fictional individual who appears in a radio program or show, such as in radio dramas, comedy sketches, or even as part of a DJ's on-air persona. Radio relies heavily on sound to build these characters and their worlds, using:

* **Voice acting:** Distinctive voices, accents, and vocal mannerisms.

* **Sound effects:** To place characters in specific environments or highlight actions.

* **Music:** To set mood and underscore character emotions.

* **Dialogue:** The primary way to reveal character traits, relationships, and advance the plot.

In summary, "text" and "character" in relation to radio stations encompass everything from the official alphanumeric identifiers (call signs) and the digital information embedded in broadcasts (RDS) to the textual interactions with listeners via SMS and the development of compelling fictional personalities through sound.
