Radio observation in hydrogen line (1420MHz)
How to point your drift detection hydrogen line radio telescope at the bright part of the Milky Way in Cygnus to test the performance of the system.
Many of the posts in the blog have discussed the development and use of hydrogen line radio telescopes, which work by pointing at the same azimuth and elevation, and on…
Cold Sky vs Hot Ground
Cold Sky vs Hot Ground: Here’s a quick test which will verify all is okay with your hydrogen line radio telescope: The difference between 10K cold sky & 290K Earth…
Obtaining the value to use for VLSR correction during analysis of amateur radio astronomy data from NRAO (Greenbank Observatory) website

Is 0.3dB going to equate to 50K antenna temperature signal over background?
Short answer: no – 0.3 dB does NOT correspond to a 50 K antenna temperature increase (unless your system temperature is very high). P2 / P1 = 10^(0.3 / 10)…

How to use Discovery Dish hydrogen line feed on LRO-H2 150cm Solar Cooker Radio Telescope Dish
Adapted from advice by Alex Pettit. Alex: The Illumination of the feed is determined by the dish<>feed spacing. For small dishes, beam forming choke rings consume too much area. The…
Detection of hydrogen on LRO-H2 at LRO using Brian Coleman’s handmade hydrogen line feed
This data was collected using ezCol (Ted Cline’s ezRA suite of software). The dish is sold as a solar cooker for use on camping trips. It makes an effective hydrogen…
