<div class="moz-cite-prefix">APRSISCE/32 reports course/speed with
the extension and doesn't do Mic-E.<br>
<br>
APRSISCE/32 also decodes everything according to the specs that
were in place when it was authored. Yes, there are different
units in different places, but they are decoded appropriately
assuming that the originators followed the spec as well.<br>

<div>I'd say the compelling reason is that the
weather data packet format on page 64 of APRS
1.0.1 says mph, so it's likely that the
majority of implementations working off the
spec already use mph. </div>

use MPH vs Knots is pretty clear, but
accepting Bob's premise: </div>
<div>* We can't change the Wind Direction/Speed
extension to mph since it's indistinguishable
from the Course and Speed extension. Where is
this extension even used? I'd vote for
deprecating it.</div>
<div>* I'd be ok changing the Storm Data report
to MPH, but I live in California so my
indifference is high on this one.</div>
