[aprssig] Good 30m Reference?

[Joel Maslak]

I'm looking for a good (and accurate) website on 30m APRS.  I'm  
adding that capability to my car (those long road trips - sick of  
having no APRS when in Nebraska [and elsewhere]).

I've found several sites, but of course they all disagree on things  
like path settings and beacon rates.

So, what I'm interested in is, ideally, a general reference for using  
30m APRS.

Failing that, what path and beacon rate should I use while mobile  
(using a 100W radio into a hamstick, won't be beaconing while parked  
or, typically, while within VHF coverage)?  I want to see the  
position get out to the internet system.

Thanks in advance
