But how fast were you moving? In what kind of terrain. Over what
distance? <br>
<br>
1200 baud is much more tolerant of mobile flutter, fading and multipath
from moving vehicles than higher data rates, because it's individual
symbols are much longer. The differences between even 1200 and 9600
on a Kenwood D700 in motion are quite dramatic. <br>

No wonder it worked! That's "cheating" - a pure line-of-sight
minimum-loss reflection-free path. Try it from a terrestrial mobile
to a base station, especially in a mountainous area or a built-up urban
area with lots of reflections from buildings, bridges, etc.<br>
