[aprssig] APRS Local Info Initative TM-D710A compatibitility

[Ron Stordahl, AE5E]

Actually I didn't mean to imply keep ALL of the object packets off of APRS-IS.  What I was trying to emphasis is that these are primarily local in application.  What I actually do is to send them locally with NOGATE every 10 minutes and then send one every 30 to 60 minutes to APRS-IS.

The radio object packets are not digipeated, certainly not out several layers where they would be QRM.  On my recent road trip I heard voice repeater objects from several hundred miles away.  It could be that some sysops don't realize this is pointless.

You can keep it off of APRS-IS by terminating the path with the string ',NOGATE'.  IGates which are working correctly will not send such a packet to the internet.  The path itself should be short, perhaps only NOGATE so that no area digipeater will repeat it.

    the radio infrastructure might be there via aprs.fi (or your favorite APRS Internet site).
