Le satellite Es'Hail 2 avec transpondeurs radioamateurs
The amateur radio transponders of the satellite
The satellite offers two transponders for amateur radio amateurs :
- A transponder for narrow-band modes (NB: Narrow band)
- A transponder for wideband television transmission (WB: Wide band)
If you would like more information about satellite, I invite you to read the introduction to my article dedicated to reception. The table below specifies the descent and ascent frequencies on which we will transmit to be retransmitted by the transponders. You notice that unlike the two bands in descent, the polarization of the rising signals is in right circular polarization (RHCP) for both transponders, wideband (for digital television) and narrowband (for signals of 2.7kHz maximum).
