What Mark states is absolutely true. I use my FLEX-5000A SDR with the 
RX2 option for full duplex operations with external transverters. See my 
qrz.com page for information on my satellite equipment.

In addition, I can call CQ,  monitor my CQ frequency and at the same 
time tune the downlink passband for other signals concurrently using the 
MultiRX capability of the PowerSDR software. If I wish, I can direct the 
CQ downlink to one ear and the other receive frequency to the other ear.

I can also view the satellite downlink's passband with the radio's 

I also use the SATPC2 tracking program for computer controlled doppler 
correction with my  FLEX-5000A.
