The RDS Transmit Window is divided into three categories:

1. General

2. Program Service

3. Buffers

In the basic section, we will cover two out of the three categories, which are the General and Program Service. In

the General category the user can set the PI and PTY data, while in the Program Service user will set the PS data

(Group Type 0). The following diagram shows a step-by-step explanation of how to do it:

Figure 29. Basic RDS Sending Message Illustration

1. First select whether you want to transmit in RDS format (Europe) or RBDS format (US)

2. Type in the Program Identification in this field. Program Identification is a 16bit code assigned to individual station.

3. Select the Program Type in the pulldown menu here. There are a lot of different program types and some of the examples

are: news, information, sports, talk, rock, etc.

4. Enter the Program Service (PS) in the boxes provided:

a. You can enter a maximum of 12 different PS messages, in which each PS message can contain a maximum of 8

characters.

b. Repeat Count: Enter how many times you want each PS message is transmitted before sending the next PS message.

c. Message Count: Enter how many of the 12 PS message that you actually want to transmit.

d. Mix: Put 100 percent here for now.

5. Click Send Message button here. Now the RDS will transmit the PS message along with the PI and PTY. You should see

these data in your RDS receiver.
