The reason CPU temperatures are capped around 100°C (212°F) comes down to a mix of material physics, electrical stability, and long-term reliability. Contrary to popular belief, the CPU
This was a casual observation as I was having breakfast today morning. The shadow of the mosquito net on my window pane was falling on the breakfast table.
The Yagi-Uda antenna (commonly just called a Yagi) is an elegant piece of RF engineering. Its working principle relies entirely on electromagnetic coupling and wave interference. Unlike some
A helical antenna is a specialized type of radio frequency antenna where the conducting wire is wound into the shape of a coil or helix, typically mounted over
Designing an End-Fed Half-Wave (EFHW) antenna for 80m through 6m is an excellent homebrew project. Because a half-wavelength wire on 80m is roughly a full wavelength on 40m,
The Peak of Solar Cycle 25 The definitive peak—or “solar maximum”—of Solar Cycle 25 occurred in October 2024. At its peak, the cycle reached a maximum smoothed sunspot
Digital Mobile Radio (DMR) has completely transformed the VHF/UHF landscape in amateur radio. Originally developed by the European Telecommunications Standards Institute (ETSI) for commercial use (like delivery fleets
Yes, QRP (low power) operation on 80 meters is entirely feasible, but it is widely considered one of the more demanding combinations in amateur radio. Success on this
A Rybakov antenna is a non-resonant, multiband vertical wire antenna widely used in amateur radio, particularly for portable field operations, camping, and temporary setups. The name comes from
