A8302 Amplitude comparator board
Admin
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…
1420Mhz data up until 29.10.2023
Collected using Ptarmigan array Processed using ezRA suite Plots below – data so far covers 2 data points – both azimuth 180, elevation 90 degrees (pointed towards Zenith) and elevation…
Dimensions of Ptarmigan Triffid Array
Whole array = 86 x 86cm in size 4 x 4 pattern of dipole aerials Each dipole = 97mm in length
Installing Ptarmigan Triffid array on new wooden mount to allow changes in elevation/altitude for radio observations at 1420.405MHz (hydrogen line)
I have now installed the 86 x 86cm military array on my new wooden mount and pointed it south Andy
Effect of retuning software defined radio to 1420.405MHz on output of ezRA suite software 22-23/10/2023
The following link will download the SDRSharp IFAverage data set from last 24 hours – resulting from retuning the SDR to 1420.405MHz – not quite sure why plots from ezRA…
