Another important matter which will assist materially is the ordering of the official license certificate for Licensed Relay Stations. This certificate is issued only to members of the American Radio Relay League who have qualified as owning and operating a practical radio relay station. The certificate is similar to the United States Government certificate, and makes a dignified document which any radio operator might well be proud of. It is sent upon paying the license fee of fifty cents, provided of course the applicant is a member of the League. If you have not obtained your License, you ought to order it at once so as to have it framed and hanging up in your operating room when the time comes that you want your station to look well. Send a dollar, and we will send your Book, package of Official Message Blanks and your License all at the same time.
