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.
