Inmarsat-4 F3 voice gone?
« on: April 10, 2022, 2103 UTC »
I went back to monitoring Inmarsat-4 F3 after a long absence. I'm picking up STD-C LES and Classic Aero 600/1200/10500 bps signals, but I don't see any 8400 bps voice signals where I saw them before (1546.130 – 1546.190 MHz). I have a note that says that 600 & 1200 bps signals are scheduled to be phased out by 2023; are those voice channels gone now, or just very infrequent? Thanks!
