in SmartSDR version 2.0 FlexRadio has introduced support for the N1MM+ Spectrum Display Feature. You can see it in action in several videos on YouTube like this one:
I wanted to know more about this feature so after some research I came up with a little app which requests and displays this data on the Mac:
For now this app connects to SmartCAT on Windows (running in Parallels on my iMac) but I'll include this functionality in the upcoming new version of xCAT.
If you are interested what data format is used you can read more about it here.
And maybe something more useful will come out of this little experiment.. :-)
