Video of changing 1420MHz plot over several days drift scan 16/10/2023
Admin
This is not a great video – but is my first attempt and shows changes in the plot with time. The telescope was pointed at the Zenith (Cygnus Complex area…
Radio observation in hydrogen line (1420MHz)
Nooelec mesh antenna tuned to 1.4GHz for hydrogen line radio observing
This new antenna from Nooelec is tuned to 1.4GHz and designed for radio astronomy – currently not available on amazon.co.uk but is available on amazon.com Currently listed as “Nooelec Satellite…

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…
