hi, i can get the information into and out of GNU radio using tropo https://www.tropo.com/how-it-works/ type application i guess!

but was interested to see working examples of how to work with the data once it has been received, for example, if i have a python script which creates a dictionary or a key:value object this then generates a unique signal then to be able to process this signal and read the  key:value object.

is my understanding correct of the process and are there any security issues with this?

>From a signal processing standpoint, sure, GNU Radio should work with
the basic idea. The issue you face is how to get the information into
and out of GNU Radio to the external world. You might be able to use
the audio I/O, but my guess is that you'll need some more specialized
equipment. Of course, I say this after a 1 minute look at that
website, so I'm sure there are subtleties that I'm missing.
