What you’re looking at
This is a cumulative view (up to 365 days) of PSKReporter reception reports for M7SQI using the appended NDJSON history.
The azimuth plots summarise where stations hear me (directional “heat”), and the distance histogram shows how far those reporters are.
Bad QRG means “someone reported me on a band I’m not licensed to transmit on as an M7” (flagging the spot as anomalous, not asserting I transmitted there).
Unknown is kept because real data is untidy and the pipeline is being honest about it.
