I don't know anything about the 2 you mentioned. I have an ifr 1200
without the spectrum analyzer. It does have a serial port and will accept
commands to read meeters and send those back out the port, so I can read
modulation and so forth with a computer program i've written. If one of
them has a ssb mode, I'd go for that one as that makes a breeze to zeroe
something on frequency. Just tune for zero beat.
