The first two streams are connected the the Radio Telescope.
Below the Telescope picture one can find the actual position of the beam. In case the EME group is active the Radio Telescope will track the moon. In such case you may find both 70cm and 23cm Moonbounced signals in these streams. When the group is not active the second stream with reflect the reception of the satellite band. When there is no EME activity, the Radio telecope may be in its 'showstand' (showing position) (30' Elevation and 30' alt-azimuth), or may be tracking astronomical objects. Live terrestrial signals and even strong satellites can be heard in the side lobes of the beam.

The other streams are generated from antennes located in the Radio Garden.
The third and fourth streams are connected to a 4 elements 144MHz Yagi at 12m AGL. This antenna is beaming in South direction. Here one can receive ISS and amateur LEO satellites. A seperate receiver shows the fourth stream for meteor scatter reflections of the French space radar GRAVES.
The fifth streem is connected to a 3 elements 50Mhz Yagi beaming South-west at 9m AGL. Here one can receive meteor scatter reflections of the Belgian Dourbes (BRAMS) beacon, the Belgian Ypres (IRIS) beacon and the RSGB/BAA (GB3MBA) beacon from the UK.
The sixth stream is connected to the 15m 'radio JOVE' antenna for the decametric radio emissions of the planet Jupiter in conjunction with one of its moons Io. However most of the time, when the ionosphere is to dense, only terrestrial signals can be heard like the 15m amateur band. The antenna is a double dipole phased array beaming South at 4.9m AGL.
The seventh stream is connected to a broadband omnidirectional Discone antenna at 15m AGL. This stream can be used for reception of 137MHz meteo satellites to generate weather pictures. Regularly AM aircraft signals are also audible.
