A comment on sharing the antenna with the SDR-IQ: I did that with my
FT-1000MP Mk V some time back and found that I got some hash on 20M fed
back from the SDR-IQ to the Mk V receive input. It that approach is
used, it's probably a good idea to use one of Jack Smith's buffer amps
between the SDR-IQ and the antenna feed.

I have just a few more comments on this. First, I have several users
running the Orion with the 9 mhz IF mod, LP-Pan, and TRX-Pan. This
works quite well and is very stable.
Second, I also have an interface with SDR-IQ. In this setup, no 9 mhz
IF output mod is needed at all on the Orion. Instead, one wire is added
inside the orion that goes between the sub-reciever antenna input and
the spare jack on the Orion. This allows SDR-IQ or the Flex 1500 to
share the same antenna with the Orion. My software keeps the two radios
in lock step, also providing a great panadapter function without the
need for a sound card or 9 mhz IF mode.
