The short-lived Radiosportverband (RSV e.V.) was founded as the GDR’s first free, national amateur radio club on March 24, 1990.
It existed until the union with the DARC later in the same year and
paved the way for the fusion.
The special event station DM30RSV (special DOK 30RSV) commemorates this process on the air between March 24 and October 30.
