[aprssig] Why Should a Digi Use a Path?

A position beacon @ 10 minutes is suggested to let mobiles know where your digi is in order to use it properly.  If you are only beaconing @ 30 or more, mobiles may not see your beacons at all.

So, for my digi, a KPC-3+, two pathless beacons every 10 minutes, but a path
of WIDE2-1 every 30 minutes and a path of WIDE2-2 every hour is suggested.
Ok, that makes sense.

I haven't implemented this yet. I'll look into adding a pathless beacon
object of the local 2M repeater.

I can see the purpose of this. I don't have Wx capabilities yet. Maybe
someday. Good maybe for others to know.

True. I currently beacon some telemetry. On the next config change, I'll
consider changing the telemetry path to pathless. 

Thanks for the explanation, Bob.
