US Military Explores Wideband Above 100 GHZ

/

Despite their potential for use in communications, radio frequencies in the terahertz and sub-terahertz ranges - that is, those above 100 GHz - are considered underutilized. The United States Air Force is about to share its plans for a radio they are hoping could change all that.

A project in the works in the US Air Force Research Laboratory is exploring the potential that radio frequencies above 100 GHZ have for secure wideband communications. The military is looking to develop an ultra-broadband radio that can adjust output power, data rate and even carrier frequency and are hoping to find defense contractors in the industry who can assist with the project.

Although frequencies in those ranges, which can be used for 6G communications, have a high level of atmospheric absorption that can restrict how far the transmissions travel, the military is hoping to capitalize on the frequencies' ability to accommodate secure channels. The Air Force is hosting an informational day for the industry next month and will be looking for defense contractors who are US citizens to get on board the project.

Early experiments have already proven successful, according to a report on the Inside Towers website. Last December, communication was achieved at frequencies higher than 300 GHZ during flight experiments by the Air Force, which has been exploring these options for almost a decade.

US Government Blocks Salvage of Titanic's Wireless

In the latest chapter surrounding controversial salvage operations at the wreckage of the Titanic, the US government is challenging a company's plans to recover the doomed ocean liner's wireless telegraph.

The planned recovery of the Marconi wireless telegraph from the wreckage of the doomed luxury liner Titanic is being blocked by the United States government, citing federal law and an agreement with Great Britain that the ship should be treated as a gravesite.

The salvage company RMS Titanic Inc., based in Georgia, had announced its plan to visit the wreck site next May to recover items - including the radio and telegraph used to send the distress call in 1912.

2023 SET Exercise to Test Skills and Emergency Preparedness

/

The ARRL Simulated Emergency Test (SET) is scheduled for 7-8th October 2023.

The SET is ARRL's annual national emergency exercise designed to assess the skills and preparedness of Amateur Radio Emergency Service® (ARES®) volunteers, as well as those affiliated with other organizations involved in emergency and disaster responses. The SET is open to all radio amateurs and partner organizations, in addition to national, state, and local officials. Besides ARES volunteers, those active in the National Traffic System (NTS), Radio Amateur Civil Emergency Service (RACES), National Weather Service's SKYWARN® Storm Spotter program, Community Emergency Response Team (CERT), and a variety of other allied groups and public service-oriented radio amateurs are needed to fulfill important roles in this nationwide exercise.

During the exercise, volunteers can assess equipment, modes, and skills under simulated emergency conditions and scenarios. Individuals can use the time to update a go-kit for use during deployments and to ensure their home station's operational capability during an emergency or disaster.

To get involved, contact your local ARRL Emergency Coordinator or Net Manager.
