AO-40 suffered a catastrophic failure

The newspaper “De Standaard” 22 Dec 2000 provides a report on the status of AO-40. On board was a K-band transponder developed by a AMSAT-ON team. The original idea was to have a 24 GHz beacon. Karl Meinzer, DJ4ZC, suggested to build a transponder. Unfortunately, the result of all these efforts was never fully operational.
