UNID Portuguese Language 6881 kHz USB 2300+ UTC 31 July 2017

[R4002]

More fishing fleet HF-SSB fishery radio HF communications Portuguese language on the 6-7 MHz area, specifically the 6765-7000 kHz range or "43 meters", often found in the 6800-7000 kHz or the 6900-7000 kHz pirate radio band for North America.

Weak two-way marine mobile radio communications chatter 6881 kHz USB or 6.881 MHz USB.  July 31st, 2017, starting at approx 2300 UTC and likely going past the 0000 UTC mark into August 2017.   

Lots of Portuguese chatter on the band tonight, have not come across any Spanish language stuff, like the freebanders usually heard on 6900 kHz 6.900 MHz and the like.  The Portuguese speaking fishing fleets seem to use random frequency steps and switch between USB and LSB mode at random, whereas the Spanish speaking freebanders or outbanders (bootleggers) seem to use 5 kHz steps and operate in a manner that is closer to amateur radio operators or freeband 11 meter CB operating style.  It's a lot easier to listen to the Spanish stuff!
