To maximize Transequatorial Propagation (TEP) on 6 meters, you need an antenna that does two things exceptionally well: focuses energy toward the horizon (low angle of radiation) and
Weather radar is one of the most critical and highly useful tools in modern meteorology, especially for short-term weather prediction and severe storm warnings. While computer models are
A balanced modulator is an electronic circuit that mixes two signals—typically an audio signal and a high-frequency radio carrier—to produce a Double-Sideband Suppressed-Carrier (DSB-SC) signal. In standard Amplitude
The T2FD (Terminated Tilted Folded Dipole), often just called a Terminated Folded Dipole, is a broadband wire antenna originally developed by the US Navy in the 1940s. In
Yesterday night there was a Western pass of International Space Station in my region starting at 2124 IST (UTC+530). I had kept my Moxon VHF/UHF Yagi pointed in
The Radioberry is an open-source, full-duplex High Frequency (HF) Software Defined Radio (SDR) transceiver designed to operate as a Raspberry Pi HAT (Hardware Attached on Top). Originally developed
A “Long John” antenna is a highly directional Yagi-Uda (beam) antenna characterized by an exceptionally long boom. Though originally an antenna from a specific manufacturer, the term is
At first glance, Amplitude Modulation (AM) seems like an archaic choice for modern aviation, especially given Frequency Modulation’s (FM) superior noise immunity. However, the aviation industry sticks to
