6250 kHz AM presumed pirate station (or maybe Voice Of The People clandestine) - I have a carrier and some audio, but the pescadores chatting away on 6249 kHz USB are owning the frequency. The 1000 Hz het makes listening borderline painful, but the guys on 6249 USB don't seem to mind. They're yakking away. 6250 kHz is an interesting choice given how busy the 6 MHz marine band is.
Nearby frequencies 6248 kHz LSB, 6255 kHz USB and 6256.5 kHz/6256.6 kHz LSB (maybe another QSO on or around 6255 at this point its hard to tell its QRM city) also active with maritime mobile SSB chatter.
