It's important to keep an eye on space weather for effective communication, especially for a ham radio operator. Solar activity can have a significant impact on how radio waves travel. I'll share some essential graphs to monitor from my website: http://bsdworld.org/. Note The graphs provided on this page …
Club members construct a Delta Loop antenna for the 40m band, using calculations and hands-on methods for installation and tuning. Through collaborative effort and practical experimentation, they achieve resonance and manage impedance, showcasing the educational value of experiential learning in amateur radio construction.
We've decided to tackle an HF 40-meter to 10-meter Delta Loop antenna for our next meetup. We picked this one because it's a multi-band antenna, which adds a challenge compared to a simple dipole.
On repeaters, in Ham Meetings, or when people talk about electricity in general, I hear the sentence, "It's not the voltage that will kill you, but the current." The idea that "current, not voltage, kills you" oversimplifies electrocution.
The Hustler 4BTV antenna is a vertical HF antenna known for its efficiency, durability, and versatility across multiple bands. However, if you want to use that antenna to tap into the 17-meter band, you'll need to modify it by adding a dedicated wire. This blog post describes how to include …
The San Mateo Radio Club is organizing a ham radio scavenger hunt. A radio scavenger hunt can be a fun and engaging way to encourage amateur radio operators to explore their skills and connect with other club members. The hunters gather clues to find the final meeting location …
A ground-plane antenna, also called a quarter-wave or a monopole antenna, is widely used in radio communication systems. It is relatively simple in design and consists of a vertical conductor, typically a metal rod or wire, mounted above a conducting surface known as the ground-plane. The ground-plane acts as a …
