style='font-size:12.0pt'>As I understand the history, there are some radios
that won't even display the 67 characters. There are/were TNC limits on
how long UI packets could be overall. Some TNCs can do longer, and the
APRS-IS carries a much longer limit. But the specification tells you what
should work. Exceeding those limits may result in unexpected behavior,
but as you've observed, there are lots of packets out there that seem quite
long.<br>
<br>
BTW, after the colon is the payload. That particular packet has a
timestamp, position information, weather, and a final comment.<br>
