If you use the built-in SD card for recording, all the metadata is there. Playing the files back in Winamp will show the system name and channel/TG tag:

VLC oddly does not show any relevant information. The
MediaInfo tool will show most of the fields:

It's missing the department information, as well as some others. Close call hits log most of the pertinent info, but strangely excludes the frequency in the logged hit. If you review the recordings in the scanner (Settings -> Replay Options -> Review Recordings) it
does show the freq/department, so the info is obviously embedded somewhere in the WAV file, I just haven't figured out where.
I found two third-party tools on the internet; one was a HTML page that promised to generate a report based on the files in a directory; the other was an Excel workbook that would do more or less the same thing. Neither worked.
PS-the  character is a non-breaking space that shouldn't have been in there. Some sort of weird artifact from Excel that got put at the end of the TG name when I generated the template.
