<div dir="ltr">I believe that the implementation of APRS in an Allstar node was to announce the node on the network and its status (Linked to?). That's what I have been using it for many years. This was not designed specifically for mobile nodes. APRS is radio-less and has no tie into the repeater/node.<br><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><br>Sincerely,<br><br>boB - W5EVH<br></div></div></div></div></div></div></div></div></div></div></div>

</span>There are two different things that could be useful:<br>
<br>
1. Repeater sends object beacons to the APRS-IS network to indicate<br>
its location, frequency, tone, maybe some status telemetry. Like this:<br>
<a href="http://aprs.fi/#!call=145*" rel="noreferrer" target="_blank">http://aprs.fi/#!call=145*</a><br>
<br>
2. Repeater runs igate software, such as Direwolf, so that repeater<br>
uses can use PTT-burst APRS transmissions to send their positions<br>
through the repeater to the internet. Ideally these would get muted,<br>
similarly to how DTMF is muted.<br>
<br>
Is the purpose of app_gps one of these two things? It looks like<br>
app_gps might be designed for mobile Allstar nodes? I must be missing<br>
something here.<br>
<br>
#1 can be done with a simple script and cron. Asterisk does not need<br>
to be involved at all.<br>
<br>
#2 could be done with Direwolf. You would need to mux the receiver<br>
audio into Direwolf. Is this possible with the driver used for the<br>
URI? I know it would be trivial on a system where alsa is managing the<br>
sound devices. An extra $5 sound fob to dedicate to Direwolf might be<br>
easier than the software solution.<br>
<br>
Just some thoughts from someone with more APRS experience than app_rpt<br>
experience.<br>
