[Lowfer] AMBC carriers

[Dexter McIntyre w4dex]

Most on this group I'm sure remembers KFI's unique carrier.  Today while 
looking through some old Argo captures I saw one of my KFI grabs.  Can 
you believe that was ten years ago?  Had I been asked I would have been 
willing to bet it was no more than five.

So I tuned in 650 kHz just wondering if I could see WSM's carrier and 
possibly any other station's carrier with Argo.  The strongest carrier I 
saw, which I assume is from WSM, was about 10 Hz high.  The carrier's 
signature certainly isn't as unique as KFI's:

I did see one other carrier very close to 650 kHz.  The FCC database 
shows no other station with much power that I think I would see during 
mid day:
