UNID pescadores or freebanders fishing fleet radio communications HF
Frequency: 6945 kHz 6.945 MHz
Mode: SSB - LSB
Language: Primarily Portuguese, but some Spanish heard (likely underneath the Portuguese)
Hearing several Portuguese speaking stations talking over each other on 6945 kHz LSB, almost sounds like there's a QSO in Spanish underneath the Portuguese chatter...lots and lots of QRM at 2300 UTC March 7th, 2018
