[VHFcontesting] "6HE" beacon?

[PY2ZX]

Hello,

During latest Comprida Island expedition (GG64, IOTA-SA-024) we heard a
strange CW signal "6HE" at 144,470 MHz, CW, pointed aprox. 60 ~ 70
degress, to our ocean toward Rio de Janeiro. Does anyone has heard
anything like that? Seems like a radio buoy with similar ID of their
counterparts on HF, but I never listen it on 2 meters. Any ideas? The video:
