ARLA/CLUSTER: Radioamadores ajudam a NASA a tentar comandar nave espacial com 35 anos no Espaço

Radio hams help attempts to command NASA spacecraft

An IEEE article describes how volunteers, including many radio
amateurs, are attempting to command
a 35-year-old NASA spacecraft, the International Sun-Earth Explorer 3 (ISEE-3)

Rachel Courtland interviews Dennis Wingo KD4ETA about the project and
mentions the Bochum AMSAT-DL team who will be using their 20 metre
dish antenna to help establish communications.

Software-defined radio peripherals built by Ettus Research (founded by
Matt Ettus N2MJI) have been purchased, which can be used to implement
modulator and demodulator programs that would once have had to be
built in hardware.

The Watts Up With That website has a more detailed article on the
project. The section about the AMSAT-DL Bochum facility mentions two
of the team, Achim Vollhardt DH2VA and Mario Lorenz DL5MLO.
The problems caused by ITAR are noted.
