Tactical Communication - The HF Renaissance in the US Army

With the invention of of satellite, tropospheric scatter, Line-of-Sight (LOS) microwave and fiber optic communication technologies, HF communication's importance slowly faded for military communication, but it is now making a resurgence in communications planning. HF has always been robust, particularly over NVIS (Near Vertical Incident Skywave) communication paths for tactical communication.
West Point Professor COL Stephen Hamilton explains why HF communication is seeing a renaissance in the US Army for tactical communication in this presentation from the Radio Club of America 2021 Technical Symposium.

Nice presentation. Using JS8 over the mountain and grabbing the nvis angle with the watchdog is way cool.

Nice video - thank you. A clear intro to ALE. We use HF + NVIS for emergency digital comms at the state-level (NJ in this case). I'm not sure what you meant by "PSK has no error correction". PSK is a modulation technique, like AM or FM. Error correction, if present, would be built in at a higher level. So I'd think that PSK modes might be designed with or without EC. Is there something about PSK that makes EC less effective? - KB2JSB

Great video sounds way low though crank up the volume next time

Hummmm……if you are doing this at ARL, you gotta be working with or for Tim.

Just seeing the majority of radio operators not unfolding antennas leaving them rubber banded in a folded condition and not keeping antenna mounts and surface in good condition it like a renaissance of cavemen leaving their caves.
