QO-100, also known as Es’hail-2 is a geostationary amateur radio satellite. It can be used by large parts of the world, including Europe, Africa, (parts of) South America and Asia. The satellite works as a linear transponder. It receives a specific range in the 2.4 GHz (13cm) band and sends it back to earth on 10 GHz (3cm). In order to generate such a 2.4 GHz signal and transmit it to the satellite conventional radio technology with transverters could be used. I chose a different route and ...| KittenLabs
Warning! This modification voids the warranty and can operate the transceiver outside of it’s absolute maximum ratings! The PlutoSDR has an internal XO (Rakon RXO3225M 40.000 MHz), which has excellent qualities like very low jitter. Unfortunatly for ham radio use, the absolute accuracy (PPM) and stability isn’t great. When generating signals in the GHz-range (like a TX-signal for QO-100 at 2.4 GHz) the error can multiply up to several kHz, much more than the signal bandwidth itself.| KittenLabs
