21cm (1420MHz) Amateur Radio Astronomy

21cm (1420MHz) Amateur Radio Astronomy

This month, the Amateur Radio Experimenters Group (AREG) have as their guest speakers Phil Lock and Bill Cowley, talking about amateur radio astronomy.

Cheaper electronics has created great possibilities for Amateur Radio Astronomy. This talk will describe a local project to receive and map the distribution of 1420 MHz signals from neutral hydrogen in our galaxy. We briefly describe the history of 21cm RA and why it’s still of great interest to astronomers. We outline some challenges over the last few years in assembling a 2m dish with custom feed, electronics and signal processing, then show recent results from our project.

The image in the thumbnail shows recent signals (May 17th) recorded over a 24 hour period for dish elevation of 53 degrees. The signal changes as the antenna points to different parts of the Milky Way.
