An excellent tutorial on how to build a portable crystal radio using a loop antenna coil inside a pizza box.  The coil that the tuning/variable capacitor resonates serves as the antenna by being a very large coil.  According to the maker, "Rimstar.Org," radio stations are found by adjusting the tuning capacitor and pointing the face of the loop at a nearby radio station. This crystal radio uses a crystal earphone and a germanium diode (1N344, 1N60, 1N91, 1N270, 1N277, or a 1N283).  Silicon diodes can be used, but the antenna may need more wire to pick up a station.  For more details, visit the author's website:  http://rimstar.org/science_electronic.  Music in this video is "The Path of The Golden King", by Kevin MacLeod (incompetech.com).  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are upda

Where there's a will there is a way, especially where stealth antennas are concerned. Nancy lives in a community for people over age 55 and older.  Her home association banned her from putting up any kind of antenna.  John Amodeo (NN6JA), the producer of the hit television program "Last Man Standing," and his friend Julian Frost (N3JF) travel to Florida to see what they could do to make a 39-ft/11.89 meters antenna fit into a 23-ft/7.01 meters attic space.  The final product is neat, clean, and totally invisible.  Best of all, the highly modified attic antenna works and lets Nancy enjoy amateur radio without the stress of HOAs and CC&Rs forcing her off the air.  An great example of amateur radio operators heldping each other.  For the latest Amateur Radio news and events, please check out the blog side bars.  These news feeds are upda

This time, Dave uses common materials from around the house and workshop to design, build, and use a simple 2 Meter Yagi Antenna made from metal coat hangers .  Since metal hangers are getting rare these days, you can use brass rods, copper wire , or even the old aluminum elements from an outdoor television antenna .  I've built a few of these crude yagis in years past and have found them very useful on portable operations or in locations where I'm a good distance from a 2 meter repeater.  This would make an excellent weekend project.  Have fun!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

Excellent video tutorial from Dave Turlock (KG0ZZ) on how to build a simple, effective 2 meter backpack quad antenna for portable or home use.  You can use fiberglass rod, arrow shafts, or bamboo for the spreaders,  Some PVC pipe can be used for the boom.  The longest spreader on Dave's quad is 30-inches/76.2 cm and the boom measures 30 7/8-inches/78.40 cm.  Dave uses #18 AWG wire for the antenna and has trimmed the antenna so it's resonant at 146.20 MHz.  This would make an excellent weekend project.  The antenna will be directional.  Have fun!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated regularly.
