“In today’s video I’d like to discuss the concept of a solar-powered field station for amateur radio emergency communications. Those of you who follow the blog, probably already know about this project. For the rest of you here is a video introduction of a concept I call the All WX Solar-Powered EMCOMM Field Station. The concept for a rapidly deployable, man-portable field station, came to me after the grid down disaster caused by Hurricane Maria. Hurricane Maria knocked out electricity and communications throughout most of the affected area, leaving hospitals in cities and distant regions, without reliable communications between them. I’m under No Illusion about amateur radios ability to completely replace network communications. However, amateur radio can provide essential Communications between hospitals and health centers, pass well & safe traffic, or create HF datanet to manage amateur radio operator resources and logistics, while no other communication services exist. – The station is powered by a PowerFilm Solar FM16-7200 thin film solar panel. – The Tent Shelter is a next gen Nortent Tipi 6 hot tipi ( teepee ) tent. The article is work-in-progress, so it will certainly adapt and change as it becomes more mature. The goals are there, and the ideas are solid. Please do join the discussion.
