Hello! On my HackRF Portapack I really enjoyed using the APRS decoder. I was receiving APRS messages all day - Usually multiple messages a minute. The last month or so I haven’t been able to receive any aprs or even see any on the waterfall. I Was able to receive these inside my house as it was a STRONG signal. Now I can’t seem to recieve it at all even driving around town. Tried both portapacks, different antennas, etc and still nothing. Wondering what happened.
