Looking at the raw packets, W6SDM-11 is only transmitting APRS position
packets, and APRS status packets (with a ">" character in the beginning of
the data). The beacons view on
aprs.fi only shows non-APRS beacons which
were not detected as APRS packets at all, but W6SDM-11 is not transmitting
any of those. The status packets are shown here:
