Hearing both sides of a long conversation on an "offset" frequency HF SSB marine channel (it is within the legal marine allocation though).  Simplex communications (many marine frequencies, in particular the ITU HF marine channel numbering plan, are half-duplex or split-frequency operation). 

Signals have been fading closer and closer to the noise floor over the past 10 minutes or so.
