AntSDR T510 1 MHz to 6 GHz and 2 GHz Bandwidth

August 19, 2026
AntSDR T510 AI Pre-Launch Direct RF Input Up to 2 GHz Baseband Bandwidth per Channel Here is an ambitious software-defined radio project for SARC members who enjoy radio, software, signal processing, and hands-on experimentation. The AntSDR T510 AI combines a high-speed RF system-on-chip with an integrated NVIDIA Jetson computing module. That pairing is intended to … Continue reading "AntSDR T510 1 MHz to 6 GHz and 2 GHz Bandwidth"

How Will Quantum Computing Change Ham Radio?

August 13, 2026
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 … Continue reading "How Will Quantum Computing Change Ham Radio?"

The Physics Behind Amateur Radio

August 12, 2026
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, … Continue reading "The Physics Behind Amateur Radio"
