A little caution and explanation with that advice...
1) True, it is 10 times longer, but when you include the packet
overhead this is more like only a factor of 2 longer.
2) The KPC-3+ TNC tracker that sends raw NMEA can actually
produce less QRM, because it can be set to PROPORTIONAL PATHING.

This accomplishes nothing in Southern California where all the
digipeaters enforce SINGLE HOP no matter what path is set into the
tracker. All you are doing is transmitting longer packets that:<br>
<br>
1) Occupy more air time<br>
<br>
2) Are much more likely to get trashed due to congestion on the
saturated channel here. <br>
