Hearing two Spanish-speaking OMs talking on 8284.5 USB. This is within the 8195 to 8815 kHz 8 MHz maritime HF-SSB band, however the frequency is slightly off (nearest ITU marine HF SSB channel is 8285 kHz USB) and is supposed to be used semi-duplex (split frequency). However, it is being used for simplex. Lots of whistling into microphones, etc.
I was going to post in this in Peskies but since its within the marine frequency allocations (technically), I'll give them the benefit of the doubt and assume they are on boats instead of being land-based stations operating in the marine bands.
