Hi,

I have just installed gnuradio companion on MacOS X, by means of  
MacPorts, in the hope of using it with rtl-sdr. The issue is I don’t see  
any ‘source’ item available for me to specify my input, when I look at  
the right hand pane. Is there something I should have configured or  
where I can find this?

Have you installed gr-osmosdr as well? GNU Radio does not come with  
support  
for the rtl-sdrs, so you need to install that as an external package.

You can also use the Find feature (Ctrl+f) to search for specific blocks  
you’re looking for instead of trying to figure out what category they  
are  
under.

Looks like that was my issue. Installing the “gr-osmosdr” port solved  
this.

Thanks

With Ctrl-F (or /) you can start a search. What kind of source are you  
looking for? The osmosdr/rtlsdr source? Do you have gr-osmosdr (and  
deps) installed?
