hi
about 7 years ago i got my opensky receiver kit. after installation everything was working just fine, i was reporting between 50-100 planes a day, which is real situation above my head here. in may 2022 it stopped working completely, with help from fr24 i did some software adjustments in my PI and it started working again - the problem is, that from then it is reporting only about 10 planes a day - planes that are no further than 5 miles. i have checked antena, cable and connections - all looks fine.
is there anything i could try to receive signals from planes flying above antena with clear view again?
thanks
