Very nice work Marcus!
Did you put your .grc file on GitHub?
FYI I’ve made some good progress on simultaneously mapping in spectral line
mode and detecting transient radio flashes.
This design is obtained with
git clone http://www.github.com/WVURAIL/gr-radio_astro
then building and running
cd gr-radio_astro/examples
gnuradio-companion NsfWatch45.grc
This uses a PlutoSdr, and modification would be required for other SDRs.
We'll be building a "mini CHIME" in the spring, with the purpose of
looking for FRBs at 611MHz in a zenith-oriented swath above the observatory.
The code is running on three Pi 4Bs and an Odroid N2.
I look for coincidences in the transient event times.
Again, great work on the map! Also I confirm that the outer part of our
Milky Way galaxy is much brighter than the inner galaxy in HI.
This puzzled me for a while.
Best Regards,
Glen
The memo points to all the GIT repositories involved.

Here's the latest version of our 21cm sky map, derived from nearly 5
months worth of data from our 21cm spectrometer instrument.
All of the real-time processing is handled, naturally, with Gnu Radio,
and then some Python post-processing.

Hi Marcus,
Very interesting. Is there any information online about how the map was
made (both GNU Radio and post-processing)?
Best,
Daniel.
Finally finalized the memo on this:
