Testing AD8302-based interferometer at LRO using Signal Generator
Admin
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

Processing additive interferometer data 21-220124 gain 50 using ezRA
Data from 21-22/1/2024 @ LRO – 5m distance between 2 x Nooelec 1.4GHz 60x100cm mesh aerials
Lessons learnt regarding interferometer yesterday!
Interferometers need hardware bias tees for SAWBird H+ 1420MHz filters with cascaded amplifiers, (which they also need as AD8302 chip requires certain level power input on SMA connectors to work)…
Advice on how to progress with my interferometer based on AD8302 amplitude phase comparator board 8/1/2024
Correspondence with Jan Lustrup: Hi Andy…. You want to test changes of phase between the ports, not frequency! Use the same frequency generator to a 2 way power splitter. One…
