The A13 Advanced Class Preservation Society is more than a gathering of friends - it is a circle of amateur radio operators who celebrate their status as the last holders of a class of license the Federal Communications Commission stopped granting nearly 26 years ago. The holders of these licenses, which are still renewable indefinitely, created the society in 2020 as a welcoming place. It became the home of a ragchew net that operates on Mondays, Wednesdays and Fridays on 14.213 MHz at 1700 UTC, with Scott Endsley, W5HVO, as primary net control.

Although 445 hams hold numbered certificates of membership in this group, they extend a welcome to any Advanced and Extra Class operators, as well as DX hams who would like to check in.

The elimination of the Advanced Class license was undertaken as a streamlining move - an action that created a three-license system that also removed the entry-level Novice Class.
