Thinking of getting a ham license (or upgrading)?

If you have never had an amateur radio (ham) license you will need to pass an exam to get one. But before you can take the examination you will need to jump through a few hoops! As a guide to what you will need at the examination, see this link. Look at item 4. You will need to bring with you an FCC Registration Number (FRN). There are links in item 4 to get you started in the process. You also must supply an email address since the FCC has stopped sending letters. There is also a video from the FCC on how to register.

Do you have a ham license but aren’t sure about your FRN? If you have a ham license you do have one! On recent versions of your license certificate your FRN is printed. If you have an older printed version, you can go to the ARRL web site and look for the call sign / name search box at the upper right. (You do not have to be a member to use this search feature.) Put your call in and see what the FCC database returns – it will include your FRN. It will also include some other information you may not be aware of. See this article to learn what is considered public information by the FCC. Keep this in mind – once published it will never be erased.

The FCC is now charging a $35 applications processing fee. The FCC will bill via the applicant’s email. The ARRL has announced a program to pay the fee for applicants 18 and under getting their first license. See the lead article at for details of the program.

The Federal Communications Commission (FCC) staff has clarified in response to an ARRL request that the new $35 application fee will not apply to most license modifications, including those to upgrade an amateur radio licensee’s operator class and changes to club station trustees. The FCC staff explained that the new fees will apply only to applications for a new license, renewal, rule waiver, or a new vanity call sign.
