Scanning the bands for freebanders, marine HF SSB traffic, pescadores, etc, I came across OTR on 6770 kHz AM (a nice surprise to see/hear them again) as well as a very strong but unmodulated carrier on 6780 kHz.  I have checked several different receivers and they all have the carrier there.  Tuning to 6780 kHz in AM mode quiets the receiver almost completely.

Not sure what this is, maybe a channel marker of some kind?  As far as I can tell, there's absolutely no modulation, just a carrier right on 6780.0 kHz.
