I could possibly be seen as slightly biased but i agree with Edson!
I have tried a number of other SDRs (including an early LIme) and for
satellite work, unless you need more than 192kHz bandwidth, the FCD+
still gets my vote. Its filtering is robust in almost any high QRM
environment and it even seems to magically survive the odd unintentional
burst of RF transmitted directly into it.
