My proposed test rig for interferometer, although I intend to change the splitter to power splitter. Andy
I still don’t think my interferometer is going to work! But here the 2 x Nooelec 1420MHz mesh antennae that will be used. Andy
I have added some extension arms to the elevation mechanism on my homemade wooden mount for my 1420MHz hydrogen array to get closer to horizon as in this photo and…
The arms of the Milky Way are beginning to emerge in my 1420Mhz radio telescope using ezRA software and 86 x 86cm ex-military array. I would particularly direct readers to…
I decided to see what output came out of the AD8302 phase comparator on my interferometer board – no aerials. Is anyone able to explain to me what I seeing…

“Completed” Radio Interferometer Receiver for 1420.405MHz Hydrogen work……well, I say completed = also needs 2 x coax cables with SAWBird+ H1M LNAs at dish end, couple satellite dishes & mounts,…
I was invited to speak to the British Astronomical Association Radio Astronomy Group on my hydrogen line radio astronomy work to date – they have uploaded a video of that…
