Having just read this....what 60 mile rule?

Subject: ECHOlink node status on APRS

APRS-IS experts:
If we let ECHOlink nodes inject their NODE status into the APRS-IS, so that
every single one of them does not have to dedicate a radio and TNC to serve
his local APRSusers, then how do we get the status that is on the APRS-IS,
injected back to RF in his local area?
Something has to trigger the local IGate-to-RF only in the vicinity of that
ECHOlink node. SO what do we put in the ECHOLINK station position packet
so that it comes out that one and only IGate?
Only thing I can think of is that the ECHOlink operator has to get his
local IGate operator to add the ECHOlinnk callsign to the GATE-TO-RF always
table. And then the ECHOLINK operator has to make sure that he does not
use that call for any other APRS stuff.
But this requires two coordinating humans, and is difficult to assure on
HAM radio. Is there an automatic way we can do this so it only requires
ONE person, either the IGatre operator or the ECHOlink operator to get
working?
The goal is for LOCAL mobiles in the vicinity of the ECHOlink node to get a
station update DIRECT on 144.39 when the node changes state... to alert
the local mobile.

Trying to find a way for the APRS-Internet to keep all objects of the SAME
name separate yet still allow LOCAL updating of objects. (and stations)...
One idea was that any update within 60 miles of a previous same-name
object/station would be considered as the SAME station and would be
replaced.
But any same-name station/object more than 60 miles away would be kept
separate. Thus Sanfrancisco and LA can both be having a LEAD runner
without it jumping back and forth...

You would have to get the local Igate to gate the station. Really no big
deal.

It should be left up to the Igate what the Igate gates.

Exactly.

It has to be up to the Igate, imho. He is the control station.
