Could Quantum Computing Change Radio and Antenna Designs? Here is a forward-looking technology question for SARC members: could quantum computing eventually change the way engineers design radios, antennas, filters, and digital communication systems? IBM and several research partners recently reported three quantum-computing results that they say reached beyond leading classical methods while adding new ways …

Understanding Electromagnetic Waves Here is a useful physics idea for Schaumburg Amateur Radio Club (SARC) members: every on-air contact begins with an electromagnetic wave. Voice, continuous wave (CW) Morse code, and digital signals all depend on radio-frequency (RF) energy traveling from a transmitting antenna to a receiving antenna. Understanding that path makes frequency, wavelength, polarization, …

Proba-3 Reveals the Sun’s Inner Corona Here is a fascinating Sun-watching idea for SARC members. The European Space Agency’s Proba-3 mission uses two spacecraft to create artificial solar eclipses in orbit. These long eclipses let scientists study a difficult-to-see part of the Sun’s atmosphere where the solar wind develops and space weather begins. That matters …

A Practical Digital-Mode Comparison Here is a useful digital-mode experiment for SARC members. WSJT-X 3.0.2 and DECODIUM 4.0 “Shannon” can both place weak-signal activity on your screen, but they approach the operating experience differently. WSJT-X remains the official reference program for FT8 and many related weak-signal modes. DECODIUM builds on that software lineage while adding …
