I guess gr-radio_astro isn't made for Ubuntu 22.04? Is there a work around to the gr_swig_make unknown command?

CMake Error at swig/CMakeLists.txt:37 (include):
include could not find requested file:

GrSwig

CMake Error at swig/CMakeLists.txt:51 (GR_SWIG_MAKE):
Unknown CMake command "GR_SWIG_MAKE".

@anthfuller - that error is probably because the default branch of gr-radio_astro (main) is still based on GNU Radio 3.7 (or 3.8) that used SWIG for the Python bindings.
Newer versions of GNU Radio (3.9 and 3.10) use pybind11.

You can build the gr-radio_astro OOT module for one of these recent versions of GNU Radio by just switching to the gr310 branch after cloning this repository, i.e.:

git clone https://github.com/WVURAIL/gr-radio_astro.git
cd gr-radio_astro
git checkout gr310
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Hope this helps,
Franco

Hi Franco!
I'll give it a try tomorrow and let you know.
Thank you!

@glangsto - I agree with you that the default branch should be compatible with gr310, since now Ubuntu LTS comes with GNU Radio 3.10.
Perhaps we could rename the current main branch to say gr37 (or something like that), and gr310 branch tom main (and make that one the default branch in GitHub).

I can definitely help with that.

Gentlemen I am up and running, thank you so much!! I'm modifying the Spectrometer_w_cal to use the KrakenSDR five channel RTL-SDR receiver. I'm only testing with two channels and an internal noise source for the moment.

I'm also currently working on a radio astronomy interferometer using two, 3-meter dishes. Hopefully I can obtain one or two more 3-meter satellite dishes, which aren't easy to come by now. Either you're ordering over seas with astronomical shipping cost or you're building your own. :-D

.@anthfuller - I am glad you got it to work.
Let us know how it goes with the interferometer; are you going to write/publish your experiments and results somewhere?

Hi Franco!

I'm hoping to get the system up and running within 30 days! The project has been long overdue. If all goes well, I'll publish all results at the Society of Amateur Radio Astronomers (SARA).

There are several issues to work out. One, I'm using a linear power source for the H1 receivers due to the equipment shed being to close to the satellite dishes. I'll also most likely line the inside of the equipment shed with Titan RF to create a faraday cage. I'm looking to motorize both dishes, but most EL/AZ rotors won't fit my pole mounts without some type of modifications (welding). So, I may have to work with actuators, one horizontal, the other altered for vertical. Not the best, but for now, until I can figure that part out or use maybe a slew drive, don't know.

@anthfuller - Thanks for the nice pictures Anthony! You have a very impressive setup there!
I am looking forward to read your results on SARA, and let me know if you need any help with the Python code.

Thank you, Franco! I definitely may require help. At the moment, I'm working on getting the Nsf-gr-radio_astro example interfaces setup, for after the data has been pulled. Particularly temperature in Kelvin and the velocity (km/sec).
