The American QRP Club was formed in June 2003, and later incorporated, as a organization of ham radio operating enthusiasts interested in low power operation - these types of hams are called QRPers. The AmQRP Club is not affiliated with any geographic area and its membership does not meet monthly as do many regional radio clubs. Instead, the AmQRP provides online information, instruction, goods and services to the general QRP population for educational and enjoyment purposes.
