<DIV dir=ltr align=left><SPAN class=265201523-03012007>I think this is really my
main objection to the proportional pathing scheme. Even up the coast here,
you don't need more than 2 hops to get all over. There's really not much
benefit unless you want to be seen in Arizona. And users who don't
understand it are probably more likely to crank their rate up higher when they
don't see their packets getting in as often as they expect. Even with
SmartBeaconing I have to remind users that when they're sitting still, bench
testing a unit, it's going to have a low transmit rate.</SPAN></DIV>

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.
