Simple Ham Radio Antennas: How to Build a Six Meter Ham Radio Dipole Antenna. Post #381.

Image
Excellent video tutorial from Randy (K7AGE) on how to build a simple, yet effective antenna for the 6 meter Amateur Radio Band. I have a similar antenna mounted on my garage roof. Although there isn't much 6 meter activity on Hawaii Island, some DX comes through when the sun gets active. Now that most lower television channels have moved away from the 50 MHz band (mostly the old analog channel 2), the band is a lot better for amateur radio contacts. Randy's instructions are clear and easy to follow. For the latest Amateur Radio news and events, please check out the blog sidebars. These news feeds are updated daily.

2. Setting up a MESH Node for Amateur Radio - WRT54G firmware install. ...Post #380.

Image
Excellent video from Kevin Reeve (N7RXE) on how to set up a MESH node for Amateur Radio using the Linksys WRT54G wireless router. Kevin says there have been a few changes since the video was produced. In late 2013, a new version of the firmware for HSMM-MESH was released. The name was also changed to Broadband-Hamnet, and there are a few changes from what is described in this video. You can get the changes here: http://hsmm-mesh.org/images/stories/hsmmmesh-step-by-step.pdf. Otherwise, the video is easy to follow and will get you and your MESH Node operating in a minimum of time.

HRN 190: CQ 'Comes Clean' (Click Bait on HamRadioNow). Post #379.

Image
Another challenging and desperate year for "CQ" Magazine. "CQ" editor Rich Moseson (W2VU) discusses the future of the troubled publication with HamRadioNow reporter Gary Pearce (KN4AQ). Moseson "comes clean" and admits there are no easy solutions to "CQ's" list of problems. As the amateur radio community has reported, "CQ" has delivery problems, unpaid authors, and a disappointed ham community within the United States. Perhaps, "CQ" needs to better identify its audience and seek readers just outside the amateur radio community, such as electronics enthusiasts, "preppers", do-it-yourselfers, computer techs, and "makers." The magazine could also do some more retro articles, focusing on restoration of old equipment and emergency communications. Perhaps "CQ" has lost its way in the rapidly expanding digital communications explosion. ARRL's "QST" has found its niche in contest...

Simple Ham Radio Antennas: Stealth 2 Meter Copper J-Pole for your HOA - Ham Radio Antenna - AF5DN. Post #378.

Image
I like this antenna idea from AF5DN. If you're stuck in a CC&R/HOA situation, this simple copper J-Pole antenna can get you on 2-meters with out attracting notice from nosey neighbors. Many years ago, I used a "homebrewed" 2-meter J-Pole made from 300 ohm television twin lead. It was ugly, but it worked. I also fitted this quickly-made antenna to a collapsable fiberglass fishing pole for portable or emergency use. AF5DN's craftsmanship and disguise routine are much better than my attempt at a "stealth" antenna. This would make an excellent weekend project.

Simple Ham Radio Antennas: Folded Dipole Antenna. Post #376.

Image
Here's a nice experimental monoband antenna that is easy to build and provides a bit more bandwidth than a single wire dipole. Stan Gibilisco (W1GV) reviews the basic theory and construction practices used to build this antenna. All you need is enough 300 ohm tv twinlead to build the dipole for your chosen frequency, some additional 300 ohm twin lead for the feed line, and a balanced tuner or a 4:1 balun to tuner combination to connect the feed line to your rig. I've built a version of this antenna for 40 and 20 meters, supported by a single fiberglass vertical mast using a sloper configuration. The folded dipole makes an excellent portable or emergency antenna. The antenna breaks down easily and can be rolled up and stored in a small plastic bag or container. For more information on this antenna, please visit http://www.sciencewriter.net. For the latest Amateur Radio news and events, please check out the blog sidebar. These news feeds are updated daily.
