Hi, I’m relatively new, had an indoor 8 leg spider for a few weeks then just upgraded to outdoor antenna setup:
FA Antenna on roof
RTL LNA Filter
PiAware (not SD image)
For the last 24 hours, it was great, picking up aircraft from San Diego to LA. Then I noticed a precipitous drop. I was getting the same ADSB messages as my non amplified indoor antenna. Graphs1090 showed this gradual decrease starting around 930AM then a precipitous drop around 11AM. I was out of the house and made no changes at the time. I’ve checked all the connections, they’re fine. I rebooted the Raspberry Pi just before 1PM. I tried manually turning off and on the bias tee, no change. Any ideas?
