Thank You Stefan,

I’ve opened a window centered on 11904.76190; this will be very helpful, much appreciated.

Thank you also for the confirmation of QRM.

Hi Jim,

[...] but I do not know the offset of my sound card clock; my sound card clock and my low-accuracy reference clock differ by 0.3Hz (+/- 1mHz over short and long time intervals), so until install an accurate clock I can only guess that my clock offset could be +/-1Hz or so. Accordingly the center frequency of the signal shown here could be +/- 1Hz or so from the indicated 8972.81

This question can be answered by tracking the signal on 11904.76190 Hz which came back, today 14:30 UTC.

Is it most likely that the signal in the attached is QRM?

R, CFM.
