Pat can attest to my reaction when I saw that screen shot. I sort of
said that I had that software and they much have an SDR-14. This was
quickly confirmed on the SDR reflectors.
So just how much path margin would one have with a 12 ft diameter C band
dish and a downconverter if we tried to see that 401 MHz signal coming
from Mars? That feed was coming from the Green Bank system!
