P-8's And Satcom Tansmissions

[tnbound]

I have 4 P-8's heading Southeast back home to Florida on ADS-B Exchange. I am also getting Satcom transmissions on 122.75 slightly garbled. Has anyone picked up Satcom in the VHF range with them before? I changed it from AM to FM and only caught the end of one of the transmission so I couldn't verify if it was the correct frequency or mode.
