Re: Transmit / Receive Text On VHF/UHF Frequency w/ HackRF One

[Marcus Müller]

Hi Adam,

The magic of GNU Radio is that wherever you put something like "Network sink/source + channel model", you could also put a hardware interface block.

So, the "Packet Communications" Tutorial from https://tutorials.gnuradio.org does apply :)

I'd recommend doing that tutorial; soon as it works through ZMQ network sockets, you can read the "Using GNU Radio with SDRs" tutorial (It's by far not as long!).

So here comes the part where I have a strong recommendations:

You want to use GNU Radio 3.8, but that's really in maintenance mode, and for people who want to interface HackRFs, is a pretty bad choice. If you get GNU Radio 3.10, you're automatically getting the gr-soapysdr interface, which means that, as soon as you install soapy-hackrf, you can talk to your hackrf – no external GNU Radio blocks needed. Also, you'll find that in the parts of the "Packet Communications" tutorial that differ between GNU Radio 3.8 and 3.9+, the 3.9+ parts are a bit shorter and "less confusing"; that is result of the GNU Radio developers trying to make packet communications less of a hassle. You really don't want to do this on 3.8.

It's not hard to install a newer version of GNU Radio; typically, all you need to do is either use a somewhat modern version of your Linux distro, or use the Radioconda installer (does also exist for Linux, not only Windows and MacOS).

Best,
Marcus

Good Afternoon,

 

I am conducting research with the Naval Postgraduate School and we’re experimenting with sending data from text files over VHF/UHF frequencies using GNU Radio with a HackRF One attached.  I have been searching through the internet and see many of the ways it used to be done have since been deprecated.  Furthermore, many of the example files provided within GNU use TCP streams or are self contained examples using artificial sources.

 

Is there anyone that can help walk through how to accomplish this using GNU Radio 3.8?

 

Thanks in advance.

 

V/r,
