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 satellite locator from AMSAT-DL is usefull for TV dish set up
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 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
F1TE PCB of minitiouner pro designed by F6DZP.
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.
