About 4 weeks ago, my collectd plot of ADS-B Receiver Tracks Seen showed a marked increase in the number of “tracks with single message”. Insofar as I could discern under the recent decline in aviation traffic, there were no other noticeable changes in my system (CPU use, range, etc.). I made no hardware adjustments, including no change to the gain of my LNA. I have noted, however, that the change occurred approximately around the time that piaware 3.8.0 got upgraded to 3.8.1. As far as I could tell from the changelog, there was nothing apparently related to what I’m seeing. See the attached plot, for reference. Has anyone else observed such a change, and/or would anyone have any suggestions as to what I could look into to troubleshoot?
