How to Build a Delta Loop Antenna.

A quick guide to building a simple delta loop antenna for 20 meters.

(http://www.youtube.com/watch?v=QJl359x6K_1).

Russ Roberts's insight:

I came across this article and video while I was searching for loop antenna ideas at my QTH.  Excellent presentation by Hiram Vazquez (WV2H), covering how to build a 20-meter delta loop and how to make a simple Q match for the antenna.  The Q match will make the antenna resonant at 50 ohms at the feedpoint.  According to Vazquez, the delta loop is bidirectional, offers some gain over a dipole (about 1.2 dB), is easy to build, and is inexpensive. Vazquez built his 20 meter delta loop in March 2012 and has worked 215 DXCC stations, with 100 watts.  This looks like a simple, effective antenna for your backyard.  I've used delta loops in the past and have found them quiet and easy to tune.  To obtain multiband use, use 300 ohm tv twin lead or 450 ohm ladder line into a balanced tuner.  If you lack a balanced tuner, feed the ladder line into a 4:1 balun and run a short length of 50 ohm coaxial cable from the balun to your antenna transmatch (tuner).  Aloha de Russ (KH6JRM).

Tony's 10-Meter Band Report, 21 August 2014.

Weak 10 meter conditions this week.  Six decaying sunspots and no solar flares to report.

Russ Roberts's insight:

A skimpy week for 10-meter contact.  Tony (G4CKC) has some choice DX, despite the genrally marginal conditions.  Interesting stations include S01WS (Western Sahara); 3E100PC (Panama); XR7PTC (Chile); ZP6DYA (Paraguay--fairly rare one); and the W1AW ARRL Centennial Stations.  As always, Tony does an excellent job of listing 10 meter DX.  The trick is to get decent propagation to receive these illusive signals.  Aloha de Russ (KH6JRM).

Solar power with a view: Transparent luminescent solar concentrators

Solar power with a view: Transparent luminescent solar concentrators | KH6JRM's Amateur Radio Blog | Scoop.it
Researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a flat, clear surface.

 

Research in the production of energy from solar cells placed around luminescent plastic-like materials is not new. These past efforts, however, have yielded poor results -- the energy production was inefficient and the materials were highly colored.

 

"No one wants to sit behind colored glass," said Lunt, an assistant professor of chemical engineering and materials science. "It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent."

 

The solar harvesting system uses small organic molecules developed by Lunt and his team to absorb specific nonvisible wavelengths of sunlight. "We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then 'glow' at another wavelength in the infrared," he said.


The "glowing" infrared light is guided to the edge of the plastic where it is converted to electricity by thin strips of photovoltaic solar cells. "Because the materials do not absorb or emit light in the visible spectrum, they look exceptionally transparent to the human eye," Lunt said.

Simple Ham Radio Antennas: The Multiband HF Stealth Vertical.

https:www.youtube.com/watch?v=Uk8XD7BP1U.

http://www.tonymilluzzi.com/2013/10/my-multiband-wire-vertical-antenna.html.

Russ Roberts's insight:

I ran across this article by Tony Milluzzi (KD8RTT) while I was searching for some stealth antenna ideas for my "antenna farm" at my new QTH in the Puna District of Hawaii Island.  Most of my wire antennas were "rearranged" by Tropical Storm Iselle on 07-08 August 2014.  Although the house survived intact, the antennas strung between several trees "bit the dust."  So, I'm rebuilding the antenna site with wire recovered from the storm. What Tony has to offer is an excellent way to rig a 40, 20, and 10 meter stealth vertical using a sturdy tree as the antenna support.  With 16 buried radials and suitable 50 ohm coax, which is also buried, Tony has an antenna that can't be seen in his HOA-restricted housing area.  He found this stealth antenna performed much better than the antenna mounted in his attic.  When I was fist licensed as a novice operator in 1977, one of my first antennas was exactly like this, the only exception being the coconut tree serving as the "mast."  Like Tony, I was surprised just how well the antenna worked.  I used this arrangement for several months until I acquired a used Drake MN-4 antenna transmatch to smooth out the small amount of SWR found in my system.  I still have the old Drake MN-4.  A suitable Norfolk Pine Tree is located about 60 feet/18.29 meters from the shack. It appears Tony's antenna will be resurrected near a rainforest in the Puna District.  I'll keep you posted.  Aloha de Russ (KH6JRM).

NAB Sues FCC Over Incentive Auction

   

The National Association of Broadcasters filed a petition with the U.S. Court of Appeals for the District of Columbia Circuit on Monday, challenging the FCC's decision to change the methodology used to predict local television coverage areas for the incentive auction.

 

Why This Matters: NAB argued that the auction framework "violates the Spectrum Act, is arbitrary, capricious, and an abuse of discretion under the Administrative Procedure Act." The association argued that the FCC’s proposal could result in significant viewership loss. 


Via David Hall
Russ Roberts's insight:

Thanks to reporter Dave Hall for this fascinating article.  I often wondered when the FCC frequency auction process would affect those who control broadcast media...now I know.  Now that the broadcast media giants are threatened by the new FCC "incentive auction process", the National Association of Broadcasters (NAB) has taken notice and has filed suit to stop the plan.The NAB contends the new auction protocol "violates The Spectrum Act, is arbitrary, capricious, and an abuse of discretion under the Administrative Procedure Act."  Perhaps, amateur radio operators and public service personnel can find an ally in our more powerful and financially stable commercial media friends.  Broadcasters are springing into action, now that their advertising and viewer numbers are threatened by the auction process.  Strange bedfellows, indeed.  Aloha de Russ (KH6JRM).

Radio World Olenicks had claimed agency rules didn’t apply in Texas

Via David Hall
Russ Roberts's insight:

It's good to see the FCC cracking down on radio pirates. The FCC has upheld a $15,000 fine against Walter Olenick and M. Rae Nadler-Olenick for operating an illegal FM station on 90.1 MHz in Austin, Texas.  The couple claimed that FCC rules and regulations didn't apply in Texas.  The FCC disagreed.  The couple has 30 days to pay up or "risk the case being turned over to the Justice Department for collection.

 

Comment: All of this would have been avoided if the couple had set up a Part 15 AM station in their apartment.  Several companies make FCC type approved transmitters for this service.  Even with restrictions of 100 milliwatts of power and a 10-foot (3.04 meters) antenna length, the signal would cover their apartment building and a little beyond.  If they really felt inspired, they could have applied for a LPFM license, now that third-channel adjacencies issues have been resolved with the FCC.  With a LPFM license, the couple could have covered a good portion of Austin from studios in their apartment.  Sorry to say, but this is a case of ignorance compounded by stupidity.  They got what they deserved.  Aloha de Russ (KH6JRM).

Radio World: This LPFM’s Time Has Come

Radio World: This LPFM’s Time Has Come | KH6JRM's Amateur Radio Blog | Scoop.it

by Mike Starling

August 20, 2014

 

The author is general manager and chief engineer of WHCP(LP), Cambridge, Md. He is former executive director of NPR Labs.

-----------------------------------------

CAMBRIDGE, Md. — For radio zealots, nothing beats building a radio station from scratch. And those of us in the low-power FM movement are relishing the day when we will soon open the microphone for the debut of what will often be the area’s first community radio station.

 

While it may appear that Democrats and Republicans in Washington seldom agree on anything, Sen. John McCain, R-Ariz., and then-Sen. Barack Obama, D-Ill., were both big supporters of the Local Community Radio Act of 2010, which relaxed the third-adjacency channel restrictions. More than 1,000 new LPFMs are currently in the pipeline.

 

Thanks to the online resources from the FCC, Prometheus and RecNets, finding an available channel and applying for the construction permit couldn’t have been easier. It beats the months of labor, thousands in consulting expenses and hundreds of pages of supporting exhibits filed when applying for my first construction permit in 1975. The FCC’s processing was a Blitzkrieg pace — an early December notice of acceptance for filing, January cutoff date and a Feb. 10 construction permit award.

Thanks to reporters David Hall and Sharon Mahoney, as well as the contributions of Mike Starling, the general manager of community radio station WHCP-FM (LP), Cambridge, Maryland for this article on the growth of low power community radio stations.  Thanks to bipartisan congressional support and new engineering studies which relaxed the third-adjacency channel restrictions, "more than 1,000 new LPFMs are currently in the pipeline."  For many isolated areas of the country, these low power stations will be the first community radio stations centered on local needs and programming.  Most of those who work at such stations are volunteers who are close to their neighborhoods and sensitive to their community's needs.  These new stations will provide vital information during emergencies and highlight community concerns.  As "Radio World" stated: "This LPFM's Time Has Come."  Aloha de Russ (KH6JRM).
