The JAERO decoder for AERO signals on Inmarsat satellites has recently been updated to version 1.03. This new version supports the decoding of 10.5k Aero-H and Aero-H+ signals. The author of JAERO Jonti writes that on these channels he’s seeing significantly more traffic than on the narrowband signals and that he was suprised to see that other non-aircraft messages such news was broadcast on this 10.5k signal. Jonti writes about his experience in developing the 10.5k decoder and his experience with receiving the messages in this post.
AERO is a system similar to VHF ACARS, but instead of running over terrestrial VHF it uses an L-band Inmarsat satellite link. Our first post about the JAERO decoder explains a bit about AERO, and this previous tutorial about decoding Inmarsat EGC messages may help you get set up with decoding Inmarsat signals in general.
Jonti discovered that news updates are also broadcast on 10.5k AERO. 
What the 10.5k signals look like compared to the 600 signals.
