in understanding differences in the position beacons I'm seeing from various<br>
stations.<br>
<br>
I'm dusting off some code I wrote a few years ago to parse APRS beacons,<br>
which at the time was decoding everything perfectly and was used on various<br>
activities.<br>
<br>
However, monitoring positional data today it's picking up beacons with<br>
differences that do not appear in the specification.<br>
<br>
Are these differences recent changes to the APRS spec, or are they clients<br>
that are just sending bad data?<br>
<br>
Monitored beacons are listed below, with a note of what I'm seeing wrong.<br>
