I'm looking for a reliable, however cheap solution for ground-space communication. I need at least 50W of transmitted power with 2GFSK modulation at 70cm band (433 MHz). Transmission will be done between earth's surface and a cubesat on LEO at 9600bps.
What should I be looking for?
Is SDR + amplifier a good solution?
Or should I aim at transceivers with capability of transmitting 50W with 2GFSK modulation (if any like that exist), or
