Radio observation in hydrogen line (1420MHz)

Today I decided to find out what happens when I take the array to point other side of Zenith (ie

Experiencing difficulties with my multiplying interferometer (which means it doesn’t work yet!), I am trying a simpler additive interferometer using

Galactic rotation curve from my data: Below shows exercise of picking points for curve above in my data: Compare my

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

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.
