Hey Mav, glad you enjoy HF... maybe we should pair up to fly together.
Alas, not just the oceanic much of the land airspace is also out of VHF range due to the lack of transmitters. No lack of land to erect them on, just lack of interest in installing them.
But luckily HF is so much fun. Can't wait for my next pleasurable hours spent listening to strident calls, on top of each other and endless repeats of information back and forth.......... waiting to get a call in on HF as I watch the lights of some city pass below.
