ok, feeling dumber yet answering my own question.

Is the logical answer to deploy a second instance of the APRS server SW here, take the firehose from CWOP's servers, then allow the internal clients to filter it to the region of interest? Running it on linux, a second instance running on the same box shouldn't be an issue should it?

You can definitely tell the CWOP feed on the Xastir status line. It's the one with the red arrow lit all the time :) Sure makes the station names zing by also on the status line.

Here's sort of a (dumb) question:

I use javaAPRSSrvr locally to aggregate all my APRS traffic from a 144.390 digi, a weather digi and two Telpac's for Winlink, as well as Xastir. This server then establishes ONE bidirectional connection to the *.aprs.net servers. If I wanted to bring in a feed from the CWOP servers, how do I configure a readonly simultaneous upstream to go along with the aprs ones? Basically, I want to aggregate it in the local instance, so I can filter, db it, etc, but NOT gate CWOP servers back to APRS-IS?

Thoughts?

At a minimum a CW station should be required to be wx and the last
four characters should be numeric I would think.

Correct. I'd also recommend that we look explicitly for APnnn, ARnnn, ASnnn and that we consider making this a user-configurable area that gets updated periodically by developers or maintainers to be "the default list"

*TOPIC 2*
Please consider connecting to cwop.tamu.eduport 30001 for gathering your CWOP data. That provides a full (nope, no filters) feed for all CWOP data including APRS-Wx (ham: not CW/DW) stations.

There are 3 CWOP-dedicated servers. These are for the CW/DW stations. Hams should continue to use the APRS-IS servers _unless_ you don't want your data pointed to RF.

Questions will be entertained. We're trying to get CWOP covered with its own servers to improve CWOP *and* APRS performance.

 >From db.c:

            // Check whether it is a citizen's weather station
            if (strncasecmp(p_station->call_sign,"CW",2) == 0) {
return(Select_.weather_stations && Select_.CWOP_wx_stations);
            }

 So no, it won't recognized DW's.  Yet.
