Lots and lots of QSOs in the 6200-6525 kHz 6 MHz marine band...these guys on 6400 kHz 6.400 MHz are coming in nicely on the sigma SDR
6400 kHz USB UNID Spanish language voice traffic...not able to put a finger on the accents outside of that.
"did you sell it at the border?" "20 yes" and other idle chatter...sounds like fishing boats...then heard "1 9 1 9" [each digit read individually], then OMs talking about their plans for later this week...then discussing "most direct route", OM replied with what sounded like navigational information but unable to make out specifics, talking about "northern" or "of the north" - perhaps giving compass bearings? - interesting QSO...
2235 UTC - after tuning around the band, I came back across 6400 kHz and the SS OMs were gone (no SSB voice at all) - but Pyongyang Broadcasting Station on 6400 AM was coming in instead...not sure if the UNID SS OMs went QRT or QSY'd due to the QRM from Pyongyang BS...
