Can't say for sure but I'm an SWL and there's an awful lot of activity on
the HF frequencies from aircraft enroute over the Carribean and Gulf of
Mexico.

Can anyone tell me if airliners typically use HF radio on this route?

It cuts close to land at the Yucatan, but not sure how the ATC is
done. VHF or HF in the remote part of the route?

Thanks
