EAMs

"Emergency Action Messages" are normal coded communications sent by the U.S. military over the high-frequency Global Communications System (HFGCS.) These are air-to-air and and air-to-ground, between military installations and resources. EAMs are a regular part of daily military communication, and there are many types, but most are low-priority. The WebSDR at UTwente is one of many that will pick up EAMs.

During an EAM you won't hear much other than the NATO phonetic alphabet being read. Visit https://eam.watch for the latest messages. When things get serious, the military uses other ultra-secure communication methods and frequencies this civilian equipment can't even pick up.  

Social media has become a cesspool of rumor and misinformation on the topic, so we see this trend often: someone posts clickbait content about EAMs, with a link to the UTwente WebSDR. People flood the site, overwhelm the system, spam the chat with rude language and trolling, and the admin shuts it off. Don't be that person. 😕

If you only want EAMs and have no other interest in shortwave, you can help ease the load on UTwente by picking a different webSDR below. Tune to 8992.00 USB or 11175.00 USB. It's normally static- you might have to wait awhile to hear anything, depending on time and current events.

Otherwise, if you're going to use the UTwente WebSDR and chatbox, please be a polite guest. Keep the conversation shortwave-centric. The majority of the "regulars" pay little attention to EAMs, but we see a lot of the same questions. That's why this site was made. We enjoy helping people learn, but ask that you do some self-education first. To really learn about EAMs, dig in here:
