Unfortunately, I still can’t get my 1420MHz interferometer to work. Have received 2 excellent pieces of advice from Jan Lustrip

I used bananas as source of radiation to test detection of radiation by pair of UKRAA Cosmicwatch coincidence detectors –

Jan kindly tested his AD8302 board to see what voltages he gets – and I have similarly tested mine today.

Interferometers need hardware bias tees for SAWBird H+ 1420MHz filters with cascaded amplifiers, (which they also need as AD8302 chip
