Calibrating Ptarmigan array antenna using background sky rather than dummy load

Admin October 13, 2023 No Comments

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…

Radio observation in hydrogen line (1420MHz)

Potential solution to making the military band 3 Ptarmigan radio array that I am using for 1420Mhz radio astronomy moveable in azimuth

Admin October 13, 2023 No Comments

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,…

Radio observation in hydrogen line (1420MHz)

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

Admin October 10, 2023 No Comments

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…

Radio observation in hydrogen line (1420MHz)

Four day drift scan of Milky Way at 1420MHz (hydrogen) using SDR+Triffid array from Lichfield, UK

Admin October 8, 2023 No Comments

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
