[aprssig] APRS-IS vs. FireNet

Lynn, I'll try to answer your questions below.

What server and port were you using on the APRS-IS?  Some ports provide pre-set filters for clients.

texas.aprs2.net mostly, using port 14580

What specific stations are you not getting from FireNet?  Exact
    callsign-SSIDs that you're no longer seeing. 


It's the recently heard list so it varies. Like when a mobile station is heard and then gets out of range, but is heard by another igate the APRS-IS will send you that stations packets for a short period of time. (One hour I think)

Your filter doesn't include any range or area specifications.  Are
    you sure that's the exact filter you were using before?

Same filter, this is a standalone igate so I don't need anything extra except NWS watches, warnings and advisories .

If you switch back to the APRS-IS connection, do the stations start
    coming in again?

Yes

If APRX has no display, how do  you do know that the packets are not
    coming in?  Are you viewing them with another APRS client, or what?

APRX runs under Unix/Linux and has a detailed log. It's easy to see when the APRS-IS sends something. I connect to it using SSH with Putty. I have had it running on a Raspberry Pi for over a year now.
