If you run it outside of the svn created directory you might need to append ~/bin to pythonpath to find the helper script. If you used build-gnuradio it'll tell you what this is at the end of the install.

Radio-quiet areas can still be found in remote parts of the world. The Murchison Shire in rural Western Australia, which houses the Murchison Widefield Array, has around 110 people living in an area half the size of Tasmania. And the new gold standard for radio astronomy will be the Square Kilometre Array, to be built in remote radio quiet zones in Western Australia and South Africa.

But what about telescopes in more heavily populated areas that can’t place a blanket ban on radio transmissions?

Unfortunately it turned out my local pagers were all using , and so not supported by any of the above software. But the procedures might still be useful for someone. Decoding FLEX can be done with the software PDW, but it is windows only. In GNU Radio there is additionally , which is supposed to support flex, but many implementation scripts for it are GNU Radio 3.6.5 or older and getting stuff to work with 3.7 requires namespace changes. mothran's is one of these. Since the rtlsdr receivers can but shouldn't do 3.125 MS/s, like flex_hackrf of uhd_flux, what they use natively for the bandwidth, and so decimation, and pretty much everything else have to be re-written too. I've attempted to start this and you can see .

Ghana is the first partner country of the African Very Long Baseline Interferometer (VLBI) Network (AVN) to complete the conversion of a communications antenna into a functioning radio telescope. The 32-metre converted telecommunications antenna at the Ghana Intelsat Satellite Earth Station at Kutunse will be integrated into the African VLBI Network (AVN) in preparation for the second phase construction of the Square Kilometre Array (SKA) across the African continent. The combination ‘first light’ science observations included Methanol Maser detections, VLBI fringe testing and Pulsar observations. Reaching these three objectives confirm that the instrument can operate as a single dish radio telescope and also as part of global VLBI network observations, such as the European VLBI network. Following the initial ‘first light’ observations, the research teams from Ghana and South Africa together with other international research partners, continue to do more observations and are analysing the data generated with the aim to characterise the system and improve its accuracy for future experiments.

An overview of the basics of radio astronomy is presented as well as ashort history of the development of radio interferometry.

I don't know much python but the python wrapper for librtlsdr was a bit easier to work with than gnu radio when I wanted to do simple things without a need for precision or accuracy. Actualy receivers with processing could be made with it too, but not by me. This is the gist of what it does,
