Hearing a long QSO on 4030 kHz USB right now.  Seems like Spanish language but I could be wrong.  Weak signals, but readable. 

Since this is a legit HF marine frequency, I'm going to presume that that's what this is.  Of course, it is right above the top edge of the 75 meter amateur band, and the 4000-4063 kHz range is known to be used for all sorts of things that are not maritime mobile.  Military/government users, MARS, pirate broadcasters, and even a peppering of licensed shortwave broadcasters from time to time (Radio Verdad on 4055 kHz AM comes to mind).  So these guys could be anything.  I've been watching them for the past 40-50 minutes on the waterfall while I listened to the UNID pirate station on 4040 kHz USB but they disappeared a couple minutes ago.  Not really sure what these guys were so I figured I'd post a log.
