Quantum Antenna?

“Promising implications for everyday uses in consumer electronics.” Sam Jarman, Phys.org Rydberg-atom sensors become antennas to detect the radio signals, performing demodulation and down conversion automatically. Rydberg receivers could eliminate significant portions of the front-end devices and electronics concerned with signal isolation when compared to conventional receivers. In a Rydberg atom, a single electron isContinue reading “Quantum Antenna?”

Club Trailer Discussion

A meeting was held this morning to discuss options for remodeling the Coos County Radio Club trailer. Various ideas were considered, including whether the club should pursue various grant sources to finance some of the work.

Ionosphere Linked to Earthquakes

Could ionospheric disturbances influence earthquakes? Researchers at Kyoto University explored how disturbances in the ionosphere exert electrostatic forces within Earth’s crust. They found that such forces potentially contribute to the initiation of large earthquakes under specific conditions. The coincidence of strong solar flare activity with the 2024 Noto Peninsula earthquake supports the hypothesis that ionosphericContinue reading “Ionosphere Linked to Earthquakes”

First Gen SigInt Sat Declassified

The NRO has declassified JUMPSEAT, the U.S.’s first-generation signals-collection satellite, which operated from 1971 to 1987. Developed under Project EARPOP, it collected critical electronic emissions and intelligence during the Cold War. The data supported national security agencies, showcasing the NRO’s ongoing commitment to innovation in space for national safety.
