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 » East
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 signal from satellite is on 10GHz band. Using a software available here we have already received transmissions from the narrow band satellite transponder with a 90 cm dish. Upload will be on 2,4 GHz. AMSAT-DL recommandation for accessing transponders can be found here.
We will soon set up this 130 cm parabolic offset dish for satellite QO-100 DATV transponder receiving demonstrations
DATV transmission will be at 2400 MHz. BATC designed the Portsdown DATV transmitter. It is based on Limesdr and RaspBerry Pi 3B+. We are presently assembling such a DATV transmitter.
Here is SV3YYO WebSDR diffusing QO-100 satellite signals from narrow band transponder captured with a similar 130 cm dish antenna we will use.
