It can be done very easily and cheaply via QO100 operation. No transceiver is required, no transverter. Only a Pluto SDR, an amplifier stage depending on the dishsize and an LNB for reception.
My portabel station for QO100:
The reason for the relatively high transmission power is only the small portabledish and 10m cable..
With 2Watt direct behind a 1.2m dish, you will get the same result in tx (and better in rx)
Only 40cm dish with 10 Watt input in a homemade poty patch antenna.
