Hamshack Hotline (HH) is a dedicated Voice-Over-Internet-Protocol (VOIP) network that is free to amateur radio operators around the world.
The goal of the Hamshack Hotline is not to replace the traffic that is carried over RF, but rather augment it when conditions are diminished or otherwise busy.
You’ll find phones in personal ham shacks, EOCs, club stations and mobile command posts.
