QO-100 teleport

A teleport for communicating via radioamateur geostationnary satellite QO-100

Apart from EME activity project and radioastronomy experiments, DP team is preparing a teleport at la Villette base radioclub station in order to receive from and transmit to QO-100 satellite from remote access.

Radiotelescope geographical coordinates are :
48° 53′ 38 »,01 Nord – 2° 23′ 18,26 » Est

AMSAT-DL recommandations for accessing QO-100 satellite transponders

This teleport will be dimensionned for using wide band DATV and narrow band signals (SSB, CW, numeric transmissions) retransmitted from both geostationnary hamradio satellite QO-100 transponders. Download from satellite is on 10GHz band while upload is on 2,4 GHz. AMSAT-DL recommandation for accessing transponders can be found here.

We plan to use a 130cm parabolic offset dish for DATV receiving demonstrations

DATV transmission will be at 2400 MHz. A BATC realization is particularly interesting: Portsdown DATV transmitter. It is based on Limesdr and RaspBerry Pi 3B+.
