Nevada ARES/RACES Members Deploy for “Storm Area 51” Event

QRZ Now - 4 hours 45 min ago

A social media joke early this summer setting up a “Storm Area 51, they Can’t Stop Us All” group now has spiraled into emergency declarations in two Nevada counties and spurred an Amateur Radio Emergency Service (ARES®)/Radio Amateur Civil Emergency Service (RACES) deployment of personnel and equipment. Some predictions say the “Storm Area 51” event will draw thousands — many possibly ill-equipped to be out in the desert environment — to the Nevada Test and Training Range, which contains the US Air Force facility known as Area 51. ARES teams plan to staff and support six incident-specific locations along the 50-mile event corridor known as Extraterrestrial Highway, starting on September 19 and continuing until September 24. ARES/RACES personnel in Nevada began gearing up for Storm Area 51 on Monday, and Storm Area 51 visitors already have begun showing up.

Secrecy surrounding Area 51 has long fascinated and inspired conspiracy theorists, who believe alien life forms recovered by the US military following UFO sightings in the 1950s are still being kept there. The events this week prompted stern warnings from the military to stay away from the site, and the FAA is reported to have closed the airspace above the area.

In June, 20-year-old Facebook user Matty Roberts called for crowds of people to rush Area 51 in the Nevada desert, to “see them aliens” that some believe are being held as prisoners there. Within days, more than 2 million indicated they were taking up Roberts’ rallying cry, and another 1.5 million expressed interest in doing so. At that point, Roberts declared that his initial post was just a joke. Multiple Facebook sites have opened since, promoting a huge music festival dubbed “Alienstock” in Rachel, a town of about 50 residents, and an Area 51 Basecamp in Hiko. Other UFO-inspired events are popping up along desolate Nevada Highway 375, Extraterrestrial Highway, effectively creating a venue more than 50 miles long, as no other roads exist into or out of Rachel. Reports say that hundreds of law enforcement officers and medical personnel will be posted, along with the Nevada National Guard.

Preliminary estimates of attendance have run as high as 100,000, and as low as 15,000. With virtually no local infrastructure and faced with the possibility of being overrun by visitors, officials in Lincoln and Nye counties declared states of emergency. When the events were first announced in late August, Lincoln County Sheriff Kerry Lee, assisted by the Nevada Department of Emergency Management/Homeland Security (NDEM), found little time to prepare. Surrounding counties and agencies are pitching in with equipment and 350 personnel.

Lincoln County, where Rachel sits, has just 5,000 inhabitants, and virtually all of the land is owned by the federal government. The county has just 20 law enforcement officers.

Emergency medical and fire protection services are nonexistent in Rachel. Volunteers staff a single ambulance, a fire truck, and a rescue vehicle. The nearest small hospital is 85 miles away, and the closest major hospital or trauma care is 150 miles away in Las Vegas. Telecommunication and other services are sparse to nonexistent along the highway, and Rachel has just one business — a small bar/café/motel combination. Its proprietor told the Associated Press, “It’s happening. We already have people from all over the world.”

ARRL Renews Request for FCC to Replace Symbol Rate with Bandwidth Limit

QRZ Now - Wed, 09/18/2019 - 4:00pm
ARRL Renews Request for FCC to Replace Symbol Rate with Bandwidth Limit

In ex parte comments filed on September 17 in WT Docket 16-239, ARRL renewed its request that the FCC delete symbol-rate limits for data transmissions in the Amateur Service rules. As it did in its initial filing, ARRL asked the FCC to couple the removal of the symbol rate limits with the adoption of a 2.8 kHz bandwidth limit. In response to a 2013 ARRL Petition for Rulemaking (RM-11708), the FCC proposed deleting the symbol-rate limits but declined to replace them with the 2.8 kHz bandwidth that ARRL wanted.

“This proceeding addresses an update to the Commission’s rules that is needed because a limitation in the rules unintentionally is inhibiting US amateurs from employing the latest improvements to some of the digital modes,” ARRL said in its remarks. “Data signals commonly used for daily communications as well as in disaster situations have bandwidths in the range of 2.5 kHz and must co-exist with other modes that use bandwidths as narrow as 50 Hz.”

ARRL said the 1980s-era symbol-rate limits now inhibit the use of some efficient data modes. “The symbol rate limit uniquely prevents radio Amateurs in the United States from experimenting and innovating with a class of modern digital communication techniques that already are widely used in other countries,” ARRL told the FCC. “The limit also impairs the ability of Amateurs to improve support that they offer in times of disaster.”

Repealing the symbol-rate limit would “allow shortened transmission times for the same amount of data without increasing the bandwidth occupied by the signal,” ARRL contended. “Other Amateurs would benefit by the resulting reduction in potential interference.”

ARRL’s remarks also addressed issues raised by other parties. “Discussion by commenters in this proceeding delve into subjects well beyond its scope,” ARRL said, noting that it had attempted to broker consensus among “some of the most active commenters” with an eye toward exploring possible areas of agreement for the FCC’s consideration. ARRL noted that the parties to the ARRL-arranged talks declined to forward to the FCC “joint recommendations on which conditional agreement had been reached.”

“The issues discussed with the parties are outside the scope of this Docket and would require a further Notice of Proposed Rulemaking before final consideration,” ARRL observed. “Some of the same issues also are raised in petitions for rulemaking on which the Commission has sought comment. Given the policy as well as factual disagreements evidenced in the record, we understand that the Commission may decide to consider some of these issues.”

One of those issues involves automatically controlled digital stations (ACDS). Commenters’ concerns focused on interference that could occur with a move away from symbol-rate criteria. ACDS with signals wider than 500 Hz and below 29.7 MHz are confined to specific subbands. ARRL recommended that the FCC consider rule changes that would have all ACDS stations and digital stations with bandwidths greater than 500 Hz share identified subbands.

ARRL said if additional signals are added to the ACDS subbands, as recommended, that it would strongly support expanding the HF ACDS subbands. But, ARRL added, “changing the subband boundaries requires study and careful consideration of trade-offs, because any changes will affect multiple user interests.” ARRL referred subband reformulation issues to its HF Band Planning Committee for study and recommendations.

Some commenters also raised the issue of obscure and encrypted messages. ARRL pointed out in its ex parte remarks that it remains opposed to encryption in the amateur bands, but disagreed “with commenters who argue that the digital modes being used by radio amateurs around the world are per se ‘obscured’ or ‘encrypted.’”

ARRL noted that FCC rules permit the use of “new and innovative digital modes” without prior approval, if specified conditions are met. Digital techniques must use approved codes with publicly documented technical characteristics, and their purpose must be to facilitate communication and not to obscure content.

“Some commenters allege that specific messages violate the Commission’s rules governing encryption, third-party messages, pecuniary interests, objectionable language, or commercial carriage,” ARRL noted, and they have called for open-source decoding software to aid in enforcing the applicable rules. “We observe that recently there have been laudable efforts at self-policing,” ARRL said. “Unresolved complaints are appropriately handled as enforcement matters rather than as rulemaking matters.”

ARRL concluded, “It is vital that the rules governing the Amateur Radio Service facilitate continuation of its experimental traditions and purposes. Using the Amateur spectrum ‘sandbox’ for innovation and development of new ideas and technologies is of significant public benefit.”d technologies is of significant public benefit.”

Festival of Frequency Measurement Set to Honor WWV Centennial

QRZ Now - Wed, 09/18/2019 - 1:15pm

HamSCI and the Case Amateur Radio Club of Case Western Reserve University (W8EDU) will sponsor a “Festival of Frequency Measurement” on WWV’s centennial, October 1, from 0000 to 2359 UTC (starting on Monday evening, September 30, in the Americas). The event invites radio amateurs, short-wave listeners, and others capable of making high-quality frequency measurements on HF to participate and publish their data to the HamSCI community on the Zenodo open-data sharing site.

“Changes in ionospheric electron density caused by space weather and diurnal solar changes are known to cause Doppler shifts on HF ray paths,” the event announcement says. “HamSCI’s first attempt at a measurement of these Doppler shifts was during the August 2017 total solar eclipse. We plan a careful measurement during the 2024 eclipse.”

Some of the questions the research event is hoping to answer include how WWV’s 5 MHz propagation path varies over a given calendar day, and how various measurement techniques for understanding the path variations compare. The objectives are to measure Doppler shifts caused by the effect of space weather on the ionosphere, and to use a specified measurement protocol available to Amateur Radio operators and other citizen-scientists. The experiment will use August 1, 2019 (UTC) as a control date.

“The recordings in this experiment are expected to show formations of the D-layer at stations’ local sunrise and other daily events of the ionosphere,” the announcement said. “Space weather varies day to day and some features may be prominent. We’ll see what we get!”

Technical specifications
  Feed specification* *the power supply can vary according to the type of installation ptional: Kit 4 elements quad for 50Mhz band                                                     235,00 € (iva incl.) On the same boom of this quad, you can apply the Kit for 3 elements quad on 50 Mhz band. The electrical features can be found on the related page of this kit: 4 StQ 50 Kit Adding this kit you will have a quad six bands full size on the same just one boom. Optional: ” Rods elements Kit ”                                                        210,00 € (iva incl.)   When ordering the quad or even later at the installation, it is possible to add the “Rods elements kit” This option is made up of the following details: – extension of the boom through a 25 mm diameter VTR tube – Mastrant 3mm tie rod, which joins the elements together and then connects them   to the boom extensions – one loop consisting of Mastrant 3mm, to be applied to all elements. The installation of this kit avoids the movement of the fiberglass elements during strong winds or snow and ice. The result is a structure that maintains a correct level of flexibility to dampen the thrust of the wind on the antenna, but never comes to overcome the critical level of mechanical stress.

Mount Diablo Amateur Radio Club Assisting in Restoring Fire-Damaged Repeaters

QRZ Now - Wed, 09/18/2019 - 7:49am

The Mount Diablo Amateur Radio Club (MDARC) Disaster Recovery Program for the 2018 Carr and Camp Fires has made a $1,000 grant to the California Amateur Radio Linking Association (CARLA) toward the cost of rebuilding one of its destroyed sites. The CARLA network of repeaters provides coverage across California and Western Nevada to provide reliable communication during significant local, regional, and wide-area incidents.

The MDARC Board of Directors has established a fund to assist organizations that have suffered ham system losses as a result of the Carr and Camp Fires, and it continues to seek additional clubs with fire-damaged systems that may require financial aid to rebuild. MDARC recognizes that many of these repeater systems are in critical areas that otherwise have very little Amateur Radio or cellular coverage, and are vital in providing important disaster traffic. Contact the club for more information. — Thanks to ARRL East Bay Section Manager Jim Siemons,
