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. 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 > On Oct 28, 2019, at 11:42 PM, Marcus D.
