Some radio stations require audio-taped PSAs that are ready to air. PSAs are read as part of a community calendar or used whenever there is spare broadcast time. It is important to contact the public service directors at radio stations to determine the preferred format and length for PSAs. Names and phone numbers included in the message should be included in your timing. If you are submitting live-copy, read the message out loud and time yourself .
Many stations prefer PSAs that are short.
Use the active voice. Use short, upbeat sentences written in everyday language. Ask for action. Indicate whether the announcement is for immediate release or for a later release date. Be available to answer questions or provide further information.
