perhaps every 10 minutes, but the path should be such that it
does not end up on the APRS-IS network nor digipeated far far
away. 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. </span><br>

Why keep such objects off the APRS-IS? If I'm planning a trip into
an area, I'd like to be able to scope it out in advance and see what
the radio infrastructure might be there via <a target="_blank" href="http://aprs.fi">aprs.fi</a> (or your
favorite APRS Internet site).<br>
<br>
Alternatively, if I'm using a contemporary APRS-IS client to see the
surrounding infrastructure and have a voice-only radio, why hide the
repeater objects from my visibilty?<br>
<br>
You're actually adding path length for NOGATE and could shorten the
packet by 7 over-the-air bytes if you just let the APRS/APRS-IS work
as designed instead of trying to keep packets "private" for some
reason.<br>
