• 2021/03/24 DARPA Announces Researchers Developing Tech to Mitigate Interference for Wideband RF Systems
  The radio frequency (RF) spectrum is a scarce resource that is becoming increasingly congested and contested as demand for spectrum access continues to grow. Within this crowded environment, the Department of Defense's (DoD) RF systems are hampered by mission-compromising interference from both self- and externally-generated signals.
• 2021/03/23 Harnessing Light to Enable Next-Generation Microwave Systems
  Electronic oscillators lie at the heart of virtually all microelectronic systems, generating the clock signals used in digital electronics and the precise frequencies that enable radio frequency (RF) sensors and communications. While an ideal oscillator provides a perfect signal at a single frequency, imperfections degrade the spectral purity of real-world components. Such impairments, broadly quantified as phase noise, ultimately limit the performance of many military radars and commercial 5G systems. The issue is becoming increasingly burdensome as the airways become more congested and defense needs evolve.
• 2021/03/18 Expanding Domestic Manufacturing of Secure, Custom Chips for Defense Needs
  DARPA today announced the Structured Array Hardware for Automatically Realized Applications (SAHARA) program, which aims to expand access to domestic manufacturing capabilities to tackle challenges hampering the secure development of custom chips for defense systems. Working in partnership with Intel and academic researchers from University of Florida, University of Maryland, and Texas A&M, SAHARA will leverage leading-edge, U.S.-based manufacturing capabilities to enable the automated and scalable conversion of defense-relevant field-programmable gate array (FPGAs) designs into quantifiably secure Structured ASICs. The program will also explore novel chip protections to support the manufacturing of silicon in zero-trust environments.

• ARISS USA Gets IRS 501(c)(3) Recognition
  08 April 2021

  ARISS-USA, a Maryland nonprofit corporation, has earned recognition from the US Internal Revenue Service (IRS) as a Section 501(c)(3) charitable, scientific, and educational organization. ARISS-USA is the US segment of the Amateur Radio on the International Space Station (ARISS) international working group. With this IRS determination, donations to ARISS-USA become tax-deductible in the US, ret...

• Traditional Amateur Radio Contesting Faces a Demographic Cliff
  08 April 2021

  Frank Howell, K4FMH, followed up his two-part National Contest Journal (NCJ) series, “The Demographics of Contesting,” with a post to his Social Circuits blog, called “Lemmings over a Demographic Cliff?” (His original articles appeared in the July/August and September/October 2020 issues of NCJ.) Howell points to data showing that radio contesters are older than the average ARRL member. Taking...

• YOTA Announces New Three-Times-a-Year Contest
  08 April 2021

  “Team YOTA” of Youngsters on the Air in IARU Region 1 has announced it will sponsor a new contest, theYOTA Contest. Open to all radio amateurs, it takes place three times a year and runs just 12 hours. YOTA said the aim is to boost on-the-air activity by younger radio amateurs and to support YOTA. The contest will take place on different 12-hour windows on three Saturdays.

  The opening event wil...
