I have now tested this aerial with RTL-SDR Blog V3 SDR and SAWBird H+ LNA – the graph below demonstrates successful data collection. Andy
Testing Right Nooelec 1.4GHz Mesh Dish 26/2/24
As part of my process for working out why I can’t get my interferometer, today I tested the right Nooelec 1.4GHz 60x100cm mesh dish. Results below = successful detection of…
Making Hydrogen-Line (1420MHz) Cantenna
At last I am having a go at making myself a Cantenna! If this works it will demonstrate that I can make a full hydrogen line radio telescope for <…
Trying to work out why my 1420MHz AD8302-based radio interferometer does not work
Unfortunately, I still can’t get my 1420MHz interferometer to work. Have received 2 excellent pieces of advice from Jan Lustrip and Mike Otte, pasted below – today I have made…
Effect interference from interferometer box on Ptarmigan array computer 13/02/2024
Click on link to read results of tests I conducted this evening that show that my Interferometer Computer Box 1-2m away from my Ptarmigan Array Computer Box significantly interferes with…
Testing AD8302-based interferometer at LRO using Signal Generator
AD8302-based interferometer uses 2 x Nooelec 1.4GHz mesh 60cm x 100cm dishes and 3 x Nooelec SAWBird H1 LNAs on each leg. Tested using Latnex Signal Generator 1.4GHz at +15dB…
Testing UKRAA Cosmicwatch muon detectors with radiation source available in every home 28/1/2024
I used bananas as source of radiation to test detection of radiation by pair of UKRAA Cosmicwatch coincidence detectors – bananas placed on top of detectors. Download my results by…
Testing voltages on outputs AD8302 board interferometer Jon Lustrup vs (Andrew Thornett) 26/1/2024
Jan kindly tested his AD8302 board to see what voltages he gets – and I have similarly tested mine today. Results below. Andy http://astronomy.me.uk/wp-content/uploads/2024/01/Testing-voltages-on-outputs-AD8302-board-interferometer-Jon-Lustrup-vs-Andrew-Thornett-260124.docx
