The following graph from ezRA suite shows successful mapping of hydrogen line across radio sky using my homemade cantenna over last 12 hours, although the later plots show that there…
Elevation 77.3 degrees Azimuth 163 from Lichfield, UK (LRO) 2/3/2024-3/3/2024, Nooelec 1.4GHz mesh antenna, Nooelec SAWBird+ H1 LNA, RTL-SDR Blog V3 Software Defined Radio. Data downloadable from link below –…
Just plugged in my homemade cantenna and the trace below on ezRA software suite (Ted Cline, https://github.com/tedcline/ezRA) immediately shows evidence of the hydrogen line – amazing how well an old…
So the orientation that I currently have my dishes in above is incorrect – I need to rotate the dishes on their tripods by 90 degrees so the long axis…
I have now successfully tested both of these dishes using ezRA suite software, RTL-SDR Blog V3 SDR and one x SAWBird hydrogen line filters/cascaded amplifier. Results of tests: Left dish:https://astronomy.me.uk/testing-left-nooelec-1-4ghz-mesh-60x100cm-dish…
I have now tested this aerial with RTL-SDR Blog V3 SDR and SAWBird H+ LNA – the graph below demonstrates successful data collection. Andy
I recently obtained these new encoders – brilliant idea for my Dobsonian telescope! Turn it into pushto GOTO. http://astronomy.me.uk/wp-content/uploads/2024/02/Geoptik-Nadirus-2BW-Instruction-Manual-Feb-2024-FULL-VERSION.pdf Andy
As part of my process for working out why I can’t get my interferometer, today I tested the right Nooelec 1.4GHz 60x100cm mesh dish. Results below = successful detection of…
At last I am having a go at making myself a Cantenna! If this works it will demonstrate that I can make a full hydrogen line radio telescope for <…
