Drift scan of Milky Way at 1420MHz using data 5-10/10/2023

I now think that my data from 5th October onwards is the best data set to use – data before this seems to produce artifacts in the data. Plots from…

Four day drift scan of Milky Way at 1420MHz (hydrogen) using SDR+Triffid array from Lichfield, UK
The following plots come from data from 4-8/10/23 = I have removed previous data which was causing some issues with data integrity. Andy
Making homemade wooden manual mount for Triffid array antenna September/October 2023
Up until now, I have been using the Triffid array on concrete blocks to point it at the zenith of the sky (straight up). In order to complete my intended…
Data from IFAverage Plug in in SDR# from LRO hydrogen line observing kit 5/1023 (ZIP file):
Software defined radio. 1420MHz filter. Ptarmigan Triffid military phased array antenna (86cm x 86cm) http://astronomy.me.uk/wp-content/uploads/2023/10/SDRSharpIFAvg_Data-051023.zip
5 day drift scan results of Milky Way through Zenith (Cygnus region) with SDR+HNA+Ptarmigan Triffid military array antenna (array antenna = 86x86cm total size)
Now got 5 days of data – day 3 not synchronised with rest – I think due to my changing part of the setup and having some issues. Andy
Frustration, Frustration, FRUSTRATION, AHHHH! Hydrogen line radio observing can be hell!
After my previous posts in which I have very excitedly described my recent successes observing Milky Way at 1420MHz, I ended up spending entire day yesterday trying to get the…
Meteor radio observations for Lichfield Radio Observatory visible on the web
My meteor observations from Lichfield Radio Observatory are now available online via the RMOB website: https://www.rmob.org/#Andrew%20Thornett Andy
72 hour drift scan through Zenith (Cygnus part of Milky Way)
My drift scan has now reached 3 days – the repeated high signal of Milky Way can be seen in plots below. Andy
When there is too much gain on VLF SID Receiver!
I am grateful to the help of Andrew Thomas yesterday for helping me to tune my very low frequency (VLF) radio receiver, which I use to detect solar flares hitting…
Results of two day drift scan of Milky Way at 1420MHz (hydrogen line) using SDR, HNA and Phased Array.
On the plot below, the bright orange areas indicate when high signal has been detected, and green dots represent my signal detection. Aerial was aimed at Zenith. In the graphs…
