That was generated by some flavour of an OpenTracker... APOTC1 on Aug 1.

N5AG-5 using UI-View32 was still beaconing an object kd5lvh (lower case)
as recently as 20 minutes ago. (this sat in my drafts folder for about a
day or so)

Most of what is seen in that log file was generated by KD5LVH-1, using
an OpenTracker...

However, then KG5LT using Xastir takes over on Aug 13 and starts
beaconing an object named KD5LVH for about 6 hours, and sometimes
killing it, according to the log file at
http://ldeffenb.dnsalias.net.nyud.net/KD5LVH.txt

During that 5 hours, there were at least a couple of beacons from an
OpenTracker...

I'm not so sure of that.

I don't think so.

I thought it was a mix of an OpenTracker, UI-View and Xastir all doing
their thing.
