Radio Astronomy

I have added some extension arms to the elevation mechanism on my homemade wooden mount for my 1420MHz hydrogen array

The arms of the Milky Way are beginning to emerge in my 1420Mhz radio telescope using ezRA software and 86

I decided to see what output came out of the AD8302 phase comparator on my interferometer board – no aerials.

Results of my first mapping exercise of Milky Way at 1420.405Mhz from Lichfield, UK, covering available sky in this area.

“Completed” Radio Interferometer Receiver for 1420.405MHz Hydrogen work……well, I say completed = also needs 2 x coax cables with SAWBird+

I was invited to speak to the British Astronomical Association Radio Astronomy Group on my hydrogen line radio astronomy work

See below for current progress on construction: My interferometer is based on Jan Lustrup’s Simple Digital Interferometer – Schematic below.
