You can probably see exactly who it is by looking at the live APRS map on


144.39 is the North-American APRS frequency and is shared by about 2000 to
10,000 other APRS packet radio operators.  Just about anyone anywhere in
the continent should hear a full channel there.  Two things to note:

1) If there is activity on the channel in your area, then you have APRS
connectivity worldwide and you can send a local packet and have it arrive
anywhere else on the planet (in other APRS areas)

2) If the signals you hear are weak or barely existant, then your area is
an APRS black-hole and needs someone to put up a TNC and old radio to
serve as a DIGIpeater for everyone else in  your black-hole...

3) Six times a day you will hear a few solid packets one a minute on that
frequency when PCsat flies over...

I see you are 64 miles east of Dallas:

> 32 degrees 50.117 minutes N
> 95 degrees 43.896 minutes W

You can see all APRS activiy LIVE anywhere in the world by looking at the
map on http://www.ae5pl.net/html/allaprs.htm

Welcome to APRS.  The worldwide packet simplex channel....
