Comparing data obtained so far with Ptarmigan array and SDR on position of galactic arms to Milky Way map
ezRA suite has produced a map of arms of Milky Way (colour on plot below) – I have overlaid a black and white map of Milky Way developed from professional…
A8302 Amplitude comparator board
Costing around £6 only on Amazon, I am hoping I can use this amazing little board based on A8302 chip in an interferometer. Ted Cline has successfully obtained interferometry fringes…
Testing the new Nooelec 1420MHz mesh antenna 4/11/23
This new mesh antenna from Nooelec is a variation on their 17.6GHz mesh antenna – except it is a little bit bigger, stalk a bit longer, waveguide significantly bigger, and…
Demonstrating that I am successfully mapping Perseus Arm of Milky Way with my 1420MHz setup 1/11/2023
I am corrected the elevations and azimuths in my data, now that I am using a compass and inclinometer on my phone to get accurate readings and completed data collection…
Galactic mapping exercise 1420MHz so far 31/10/2023
3 different altitudes so far, all at 163 degrees azimuth (I used compass to day to check my “180 degrees azimuth” and it is actually 163 degrees) from Midlands, UK…
Nooelec mesh antenna tuned for 1420MHz
I recently received one of these from Amazon – at first sight it looked like it was the same as the same company’s 1.7GHz GOES mesh dish, but with larger…
Sorting humidity problem with computer under 1420MHz array 29/10/23
Terrible humidity problem – I had mounted receiver on piece of wooden board and fungus growing on it and each morning the box is dripping inside! So, today, I have…
