“Black Swan 18” Exercise to Test US Government/Amateur Radio Interoperability on 60 Meters

QRZ Now - Wed, 10/03/2018 - 2:51pm
Emergency Management Agencies

“Black Swan 18” is a communications exercise aiming to test how well responders, emergency management agencies, and non-government organizations (NGOs) activate, operate, and complete communication missions, specifically in terms of the volume, accuracy, and speed of radio traffic. The scenario for the October 4 – 10 Black Swan 18 will be a series of winter storms and associated events. ARRL Field Organization teams have been invited to adapt this activity as the basis of their annual Simulated Emergency Test (SET). Operational periods by participating organizations should not exceed 48 hours.

“In a high-impact disaster, response will need to include many organizations bringing their unique expertise and resources to bear in a coordinated fashion,” the Black Swan 18 announcement explains. “Black Swan 18 will test this ability to operate across geography and among complementary organizations. Cooperating forces include the Ohio Military Reserve (2nd Battalion), the ARRL Ohio and Iowa sections, and Air Force MARS.”

For this exercise, communication between US government radio stations and Amateur Radio stations is authorized on the five channels at 5 MHz where the Amateur Service has secondary status. Exercise communications must yield to real-world emergency communications. Interoperability will remain in effect for the duration of the exercise.

amzn_assoc_placement = "adunit0"; amzn_assoc_enable_interest_ads = "true"; amzn_assoc_tracking_id = "qn0c-20"; amzn_assoc_ad_mode = "auto"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_linkid = "4969cf2edaec6bf602678d298f572f59";

The exercise will run in three stages:

1. “Build-Up” is October 4 – 5, when organizations involved in preparation for large events or response to localized emergencies may wish to participate.

2. “Intense Action” is October 6 – 7, when most organizations will be establishing operating stations and handling radio traffic in support of emergency preparation, response, and recovery. Organizations that cannot participate during the “Intense Action” timeframe may run their own exercises in any 48-hour window during the scenario.

3. “Recovery” is October 8 – 10, when organizations preparing for and engaged in recovery operations may wish to participate.

Localized severe weather events and effects may cause activation in the week before or the week after the scheduled timeframe.

Ohio Military Reserve will provide exercise controllers on SHARES stations NNO5HA, NNO5HD, and NNO5HG. This activation has been approved by the FEMA Spectrum Manager.

AMSAT’s Fox-1Cliff CubeSat Ready !

QRZ Now - Wed, 10/03/2018 - 12:54pm
Fox-1Cliff CubeSat

AMSAT reports that Vice President-Engineering Jerry Buxton, N0JY, delivered and integrated its Fox-1Cliff CubeSat into the launch vehicle on September 24, in preparation for sending it into orbit later this year. AMSAT has purchased a commercial launch opportunity for Fox-1Cliff and has been seeking contributionsto cover its costs. The Fox-1Cliff CubeSat was named in memory of long-time AMSAT member, contributor, and benefactor Cliff Buttschardt, K7RR (SK), who died in 2016.

“This is the last step for AMSAT Engineering in getting one of our satellites to orbit,” Buxton said in a YouTube video that explains what is involved in the final step of getting an Amateur Radio CubeSat to orbit. He explained, “Spacecraft integration is the process of mounting the spacecraft on the launch vehicle.” He pointed out that a spring-loaded “dispenser” propels the CubeSat into orbit from the launch vehicle.

Fox-1Cliff will have FM voice uplink frequencies of 435.300 MHz and 1,267.300 MHz (67.0 Hz CTCSS tone), and FM voice and AFSK digital data (up to 9,600 bps) downlink on 145.920 MHz. The nominal transponder power is 600 mW. Because only one uplink frequency can be active at a time, use of the Mode L uplink is limited to experimental periods announced in advance.

 

amzn_assoc_placement = "adunit0"; amzn_assoc_enable_interest_ads = "true"; amzn_assoc_tracking_id = "qn0c-20"; amzn_assoc_ad_mode = "auto"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_linkid = "4969cf2edaec6bf602678d298f572f59";

Fox-1Cliff carries the flight spare of the AO-85 Vanderbilt University Low Energy Proton (LEP) radiation experiment, and the standard Fox-1 Penn State University-Erie gyroscope experiment. Virginia Tech provided a VGA camera, which is the same as the camera onboard AO-92 offering 640 × 480 image resolution. These non-SSTV images will be decoded in the FoxTelem software.

Unlike the other three Fox-1 FM spacecraft, Fox-1Cliff does not have an active AFC on the uplinks.

Fox-1Cliff’s Subaudible Telemetry (low-speed telemetry) will be the same as that on AO-85, AO-91, and AO-92. It will be supported by the same FoxTelem software already released.

Buxton said Fox-1Cliff will share dispenser space with ExseedSat-1, a CubeSat built by an eight-person team at Exseed Space Innovations Private Limited, based in Hyderabad, India, and co-founded by Ashhar Farhan, VU2ESE, the designer of the µBitX SSB/CW transceiver. Farhan and engineer Gurudatta Panda, VU3GDP, were on hand for the integration. ExseedSat-1 carries an Amateur Radio FM transponder and APRS digipeater, with a repeater, digipeater, and telemetry downlink of 145.900 MHz FM, and a repeater and digipeater uplink of 435.340 MHz.

“Get Your Park ON” Operating Event Set for October [ Earth Science Week ]

QRZ Now - Wed, 10/03/2018 - 8:34am
Earth Science Week

What is hoped will be the first annual “Get Your Park ON” operating event will take place October 14 – 20, in celebration of Earth Science Week. The event is open to Amateur Radio operators around the world and is sponsored by the national affiliates of World Wide Flora and Fauna (WWFF), which encourages radio amateurs to operate outdoors in protected nature parks.

During this on-the-air celebration, hams can participate in one of two ways. North American hams can opt to be Activators, setting up and operating in geological and nature centers such as national and state parks and forests, national monuments, and protected nature habitats. They also may decide to be Hunters, operating from home and searching out and making contact with the Activators.

“We are trying to have parks activated in all states of the USA and Mexico and all Provinces of Canada,” the sponsor’s Facebook page notes. “Let’s have some fun.” The week-long special event is reminiscent of ARRL’s popular National Parks on the Air (NPOTA) event in 2016 but extends to a larger set of national treasures beyond those managed by the National Parks Service.

(adsbygoogle = window.adsbygoogle || []).push({});

The American Geosciences Institute in October 1998 organized Earth Science Week, a national and international event to help the public gain a better understanding and appreciation for the Earth sciences and to encourage stewardship of the Earth, a common goal shared by WWFF. Both programs encourage participants to get outside and enjoy nature.

 

“Get Your Park ON” gets under way at 0000 UTC on October 14 and continues through 2359 UTC on October 20. Visit the “Get Your Park ON” Facebook page for more.

 

Earth Science Week 2018 engages young people and others with learning resources and activities exploring the relationship between the arts and the Earth systems. This year’s theme of “Earth as Inspiration” promotes public understanding and stewardship of the planet. Of special interest to the Amateur Radio community and their families is an “Inspired by Earth” photo contest and an essay contest for students in grades 6 through 9. — Thanks to Norm Meyers, N9MM

Rugged: 
Rated for 90 MPH, aircraft grade aluminum.
Selection: 12′, 16′, 20′ and 28’ foot vertical dipole antennas.

Free Domestic Shipping | Easy International | Made in USA

Our designer has calculated antenna efficiency < 90% if a remote ATU is used at or near the feed point. Here is an animated GIF with the radiation angles for each band. Note there is no significant pattern breakup until 6m, you can’t say that about a 43 foot vertical!

These antennas are built rugged yet designed with quick deploy and quick take-down, portable or permanent installation in mind. Our HF Antenna Flagpoles are designed, engineered and manufactured in the USA by a team of veteran radio amateurs just like you who see a need for smart solutions in our shortwave, ham radio culture.

(adsbygoogle = window.adsbygoogle || []).push({});

Easy Install too! Simply dig a post hole, “drop-in” your new flagpole antenna, plug in your coax and you are QRV. Customers say unbox to on the air in under 2 hours. Also, these are Tilt-up, Tilt-over, and concrete or bulkhead mount ready!

NEW UPGRADED DESIGN FOR THE HAM RADIO SEASON AHEAD. Meet our:

  • 20-foot tall aircraft grade aluminum antenna with PVC in-ground “Drop In” sleeve (tilt-mounts are great too!) You’ll want a 2″ OD
  • Off-Center Fed Vertical Dipole design means no radials, 90% efficient or better across 80m to 10m
  • Internally routed Bury Flex 9914F coax cable feedline helps lower visual impact
  • Simple installation with just a shovel, no concrete needed in most installations (some do, some don’t, either okay)
  • Heavy duty fiberglass center, base insulators, and stainless steel hardware
  • Integrated common mode choke with six Type 31 ferrite beads terminated in Amphenol PL-259 
  • Available with an American flag (or DX Flag) and flag accessories for stealth operation
  • A versatile, smart option for FT8 and SDR mode operations

Our Vertical Dipole OCF Antennas (Off Center Fed) are an improvement from the various “best sellers” we see on the market. Our Greyline Performance upgrades to the DX Flagpole Antenna involve minimizing losses, finding every .db we can out of the antenna heights we offer and enhancing take-off angles too. Using EZNEC Pro software and decades of antenna design experience, we’ve found that our DX Flagpole and its non-Flag cousin, the OCF Vertical Dipole compete and beat the typical 1/4 wave requiring radials versions!

Again, the DX Flagpole offers a stealthy demeanor antenna that radiates efficiently! Also, as some have requested a quick and easy deploy portability we think this antenna lends itself as a great fit for Field Day, Motor Homes, Camping, Scouting, Second homes, Beach homes, Emcomm, and Airline Compliant for DX travel “fun-mode” Contesting, and more… What will you use it for?

Q. How does the Flagpole Antenna compare to other well-known antennas?
A. See below comparative graphs that give you a good idea of it’s “reach.” A worthy note here is that many of the compared antennas are of a different design that requires radials to work properly often bristling with stubs, traps, loading coils, and capacitive hats and in some cases are much taller. The OCF Flagpole really holds its own and is a stealth antenna, too! 

Look at the low-band (40/80M) results versus the 43′ vertical with radials. Also, worth noting is the pattern breaks up on 10M on the 43’er. Expect ham radio confidence with the DX Flagpole and it’s Vertical Dipole cousins down to 80M!

Q. What’s the difference between a 12′ 16′ 20′ and 28′ Flagpole?
A. We are surprised to find and report very little loss when dropping to the 16 and 12′ foot designs. Those in those more restricted heights can enjoy a little more confidence in working DX! 

Flagpole Backstory:

Many hams have asked for optimized antennas for multiple band operation, so we challenged antenna designer, QST author, and an inhabitant of a neighborhood where towers and Yagis would not go down well, John Portune, W6NBC, to come up with a compact vertical dipole which would be ATU “friendly” delivering good-to-excellent VSWR matches on all bands 80m through 10m with popular autotuners, in particular, the new breed of outdoor rated units. John delivered, in spades. John opted for an OCF design which makes it easier in most cases for ATUs to find a good match across a wide range of frequencies.

We didn’t cut any corners! Tubing is aircraft grade 6063-T832 aluminum, 2-inch OD top to bottom, thick fiberglass insulators at the feed and base, stainless hardware, Davis RF Buryflex coax and genuine Amphenol PL-259 connector for the pigtail, plus six Mix 31 ferrite beads from KF7P Metalwerks for the common mode choke.

We have tested the new RF Flagpole Antenna Line with several ATUs including the MFJ-998RT and MFJ-993BRT. All worked excellent on all bands 80m through 10m. For similar results we urge the use of the Flagpole antennas with an outdoor ATU located near the base of the antenna to keep feedline losses to a minimum, however, this antenna will work with many indoor ATUs and even some rig ATUs (we have tested with the Flex-6700 ATU). 

amzn_assoc_placement = "adunit0"; amzn_assoc_enable_interest_ads = "true"; amzn_assoc_tracking_id = "qn0c-20"; amzn_assoc_ad_mode = "auto"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_linkid = "4969cf2edaec6bf602678d298f572f59";

ATU Mounting Disclaimer: Again, we urge the position of the ATU at the base of the Flagpole antenna for best results. We can’t guarantee performance across all bands when the Flagpole is used with indoor ATUs as the feedline between the ATU in the shack and the antenna is an impedance transformer itself which could cause a very high mismatch on one or more bands, plus many built-in rig ATUs have limited adjustment range. We still urge the ATU must be mounted at the base for respectable performance results.

Below is a typical SWR chart from the field. Results vary with coax length and tuner position, of course. Expect a match and efficient radiation patterns.

Spray-On Antennas Could Be the Wave of the Future

QRZ Now - Tue, 10/02/2018 - 12:32pm
Spray-On Antennas

Researchers at Drexel University’s College of Engineering report a breakthrough in nanomaterials technology that promises to make installing an antenna as easy as applying sunblock or bug spray. The University reported the research in a DrexelNOW article, “Drexel’s Spray-On Antennas Could Be the Tech Connector of the Future.” The advance could mean wearable and invisible antennas that could find their place in the next generation of the Internet of things (IoT), and even have Amateur Radio applications.

“The ability to spray an antenna on a flexible substrate or make it optically transparent means that we could have a lot of new places to set up networks,” said Drexel Wireless Systems Laboratory Director and engineering professor Kapil Dandekar, a co-author of the research published recently in Science Advances.

“This technology could enable the truly seamless integration of antennas with everyday objects which will be critical for the emerging Internet of things,” Dandekar said.

In their paper, Dandekar and his colleagues laid out a method for spraying invisibly thin antennas made from a type of two-dimensional metallic material called MXene — a conductive, two-dimensional titanium carbide material — which can be dissolved in water to create an ink or paint. They said the exceptional conductivity of the material enables it to be employed as an RF radiator even when applied in a very thin, nearly invisible coating. The MXene antennas perform as well as those now being used in mobile devices, wireless routers, and other devices, the Drexel researchers said. In addition, the MXene materials were shown to be 50 times better than graphene and 300 times better than silver ink antennas in terms of preserving the quality of RF transmission.

“Current fabrication methods of metals cannot make antennas thin enough and applicable to any surface, in spite of decades of research and development to improve the performance of metal antennas,” said Yury Gogotsi, director of the A.J. Drexel Nanomaterials Institute, who initiated and led the project PhD. “We were looking for two-dimensional nanomaterials, which have sheet thickness about 100,000 times thinner than a human hair; just a few atoms across, and can self-assemble into conductive films upon deposition on any surface. Therefore, we selected MXene as a candidate for ultra-thin antennas.”

“The MXene antenna not only outperformed the macro and micro world of metal antennas, we went beyond the performance of available nanomaterial antennas, while keeping the antenna thickness very low,” said Babak Anasori, a research assistant professor in the A.J. Drexel Nanomaterials Institute. “The thinnest antenna was as thin as 62 nanometers — about a thousand times thinner than a sheet of paper — and it was almost transparent.”

 

(adsbygoogle = window.adsbygoogle || []).push({});

Unlike existing nanomaterial fabrication methods that require several steps, the Drexel research team’s spray-on antennas can be fabricated in a single step by airbrush spraying a water-based MXene ink, Anasori said. — Thanks to DrexelNow

The Chill of Solar Minimum

by DR.TONY PHILLIPS – spaceweather.com

The sun is entering one of the deepest Solar Minima of the Space Age. Sunspots have been absent for most of 2018, and the sun’s ultraviolet output has sharply dropped. New research shows that Earth’s upper atmosphere is responding.

“We see a cooling trend,” says Martin Mlynczak of NASA’s Langley Research Center. “High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy. If current trends continue, it could soon set a Space Age record for cold.”

These results come from the SABER instrument onboard NASA’s TIMED satellite. SABER monitors infrared emissions from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air 100 to 300 kilometers above our planet’s surface. By measuring the infrared glow of these molecules, SABER can assess the thermal state of gas at the very top of the atmosphere–a layer researchers call “the thermosphere.”

“The thermosphere always cools off during Solar Minimum. It’s one of the most important ways the solar cycle affects our planet,” explains Mlynczak, who is the associate principal investigator for SABER.

When the thermosphere cools, it shrinks, literally decreasing the radius of Earth’s atmosphere. This shrinkage decreases aerodynamic drag on satellites in low-Earth orbit, extending their lifetimes. That’s the good news. The bad news is, it also delays the natural decay of space junk, resulting in a more cluttered environment around Earth……READ FULL ARTICLE
