Around an year ago thank to this forum support I've set up a radar using:
- Jetvision A3 ADS-B antenna
- Uptronics 1090MHz ADS-B Filtered Preamp filter
- dump1090-mutability on Raspberry Pi B
Do you have any idea why it could happen?
My guesses:
- Antenna/cable from roof damaged: I've checked but all of them seems ok;
- Filter is not working anymore: actually I've noticed that unplugging the power to the filter (but keep all the others cables connected) does not change the range significantly. I've run the heatmap.py in three situations, here are results https://imgur.com/a/AIWyeKO. What seems strange to me is that nothing is showing around 1090 MHz when filter is inserted, but unfortunately I haven't any image of when everything was working. I remember anyway that before buying the filter I had a better range compared to no filter situation now, so I think that the problem is not the filter.
- I've completely updated and restarted the rasp, so the problem seems not be software.
