27,195 kHz
MFSK data bursts, extremely frequent, often data signals on top of each other, bandwidth roughly 5 kHz or so - 5K00F2D 5K00F1D emission, other data signals with 4.5 kHz bandwidth 4K50F1D 4K50F2D
At 1933 UTC, AM voice signals also appeared on frequency, one carrier on 27194.9 kHz, another on 27194.8 kHz and the "primary" one appears to be on 27194.5 kHz. The AM voice signals are being drowned out by the data bursts (really more like a non stop data stream at this point) so unable to ID the voice users.
