What does the FCC mean by “associated valid call sign”?
Your call sign is listed on your FCC Wireless Telecommunications Bureau license. Your radio operators will know where your licenses are; they should be posted near the point where they are used. Call signs other than those issued by the Wireless Telecommunications Bureau do not have to be registered by this time. For example, broadcast call signs are issued by the Mass Media Bureau and do not have to be registered. You can also look up your call signs on the web. Go to the Wireless Telecommunications Bureau homepage at http://www.fcc.gov/wtb/. Under the General Information Section, click on the link for “Search the WTB Databases Online.” Click the link for Licensee (Service) or Licensee/Zip and then type in your name or your organization’s name and change the number of rows to retrieve to “ALL” and click OK.
