Another question:  you say you're reporting "independently through CWOP" --
is your data going into APRS via that independent means using the same 
callsign/ssid as your Xastir station, and are you receiving these reports
into Xastir through an APRS-IS connection?  Do any other WX stations in your
APRS-IS feed show the same behavior?

I'm looking through the source code, and Xastir *is* trying to do the right
thing with "complete weather reports" (the ones where course/speed looks
exactly like a station's course and speed, but with additional data being 
present to make it clear that this is a wx report, not a moving station).
But I'm wondering if Xastir sees the data as being its own (because of matching
callsign/SSID), and adding the course/speed to its internal record of its 
own course/speed before it goes on to parse the weather parts of the record.

Does the behavior change if you change the callsign/ssid of Xastir to something
different than your external program that's feeding CWOP?
