10-10 International
Ten-Ten International Net, or 10-10 for short, is an organization of [[amateur radio]] operators dedicated to maintaining high levels of amateur radio communications on the [[10_meters|10-meter]] amateur band (28.0-29.7 MHz). Established in 1962, 10-10 has grown continuously since that day, with some ups and downs according to the numbers of [[sunspots]] and the openness of the band. As you read this, the number of 10-10 numbers issued to members is over 70,000. 10-10 would welcome your membership in the organization if you have an amateur radio license with 10-meter privileges.
