Calibrating Ptarmigan array antenna using background sky rather than dummy load
In my previous posts, I calibrated my 1420 MHz radio telescope using a 50 Ohm dummy load. This worked well. However, since Monday, we have been in Italy and day…
Potential solution to making the military band 3 Ptarmigan radio array that I am using for 1420Mhz radio astronomy moveable in azimuth
I have found an 800mm wide Lazy Susan bearing on ebay, hardened against weather, with 250kg load capacity, and am hoping to place the whole mount on top of this,…
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…
