Regulatory: ARRL to FCC: "Grow Light" Ballast Causes HF Interference, Violates Rules

The ARRL has formally complained to the FCC that a "grow light" ballast being widely marketed and sold is responsible for severe interference to the MF and HF bands. The League urged Commission action to halt sales of the Lumatek LK-1000 electronic ballast and to recall devices already on store shelves or in the hands of consumers. In a March 12 letter, ARRL General Counsel Chris Imlay, W3KD, told the FCC Enforcement Bureau and its Office of Engineering and Technology (OET) that, during ARRL Laboratory testing, the Lumatek device exhibited conducted emissions that exceeded FCC rules.

The Lumatek LK-1000 electronic ballast.

"ARRL has received numerous complaints from Amateur Radio operators of significant noise in the medium and high frequency bands between 1.8 MHz and 30 MHz from 'grow lights' and other RF lighting devices generally," Imlay said in the complaint. "The level of conducted emissions from this device is so high that, as a practical matter, one RF ballast operated in a residential environment would create preclusive interference to Amateur Radio HF communications throughout entire neighborhoods." An extensive Conducted Emissions Test Report detailing the ARRL Lab's test results was attached to the League's correspondence.

"[T]he Report concludes from the conducted emissions tests that the six highest emissions from the device in the HF band vastly exceed the quasi-peak limit specified in Section 18.307(c) of the Rules," Imlay told the FCC. The ARRL further pointed out that, while an FCC sticker had been affixed to the device, it lacked FCC compliance information. FCC Part 18 rules require RF lighting devices to provide an advisory statement with such a device, notifying users that it could interfere with radio equipment operating between 0.45 MHz and 30 MHz.

The League noted that the device is imported into the US and marketed and sold by Sears, where ARRL purchased its test sample, as well as by and other retail outlets. The ARRL also called on the FCC to consider enforcement proceedings against the importer, Hydrofarm Horticultural Products of Petaluma, California. Read more.

Regulatory: FCC Consent Decree Requires Radio Amateur to Relinquish His License

As part of a Consent Decree ending an enforcement action against him, a Cocoa, Florida, radio amateur has agreed to give up his Advanced class Amateur Radio license. Terry L. Van Volkenburg, KC5RF, also has agreed to make a $1000 "voluntary donation" to the US Treasury, in installments, and waive all rights to contest the validity of the Consent Decree, released March 19.

In turn, the FCC is terminating a 2012 enforcement proceeding against him involving unlicensed transmissions that interfered with a sheriff's department radio system. On March 1, 2013, the FCC found Van Volkenburg liable for a $25,000 forfeiture, which the Commission subsequently determined he would be unable to pay. The Enforcement Bureau also agreed not to institute any new proceeding on the basis of the one just concluded.

The Commission said it was entering into the agreement and terminating the enforcement proceeding in part, "to avoid further expenditure of public resources."

Prior to signing the Consent Decree, the FCC said, Van Volkenburg requested in writing that the Commission cancel his Amateur Radio license.

The FCC investigation began in September 2012 in response to an interference complaint filed by the Brevard County Sheriff's Department. The Enforcement Bureau subsequently determined that Van Volkenburg transmitted on 465.300 MHz without a license, interfering with the radio system in the county jail.

In settling the enforcement action, Van Volkenburg "admits, solely for the purpose of this Consent Decree and for Commission civil enforcement purposes" that the radio transmissions he made on 465.300 MHz sparking the investigation violated the Communications Act.

Regulatory: FCC Invites Public Comment on Petition Affecting 10-10.5 GHz Band

The FCC has invited public comment on a Petition for Rule Making (RM-11715) that would make a significant portion of the 10.0 to 10.5 GHz band available for wireless broadband services. The Petition by Mimosa Networks Inc proposed a band plan for 10.0 to 10.5 GHz that, it said, would protect frequencies most often used by radio amateurs. The petition hinges on FCC adoption of rule changes that would put the 10 GHz band under Subpart Z of the Commission's Part 90 rules. Subpart Z currently sets out regulations governing wireless licensing, technical standards, and operational standards in the 3650 to 3700 MHz band.

"[T]he application of the coordination procedures and requirements provided in Subpart Z will ensure that Amateur Radio operations in the band will not be disrupted," Mimosa told the FCC. "In addition, as a further safeguard, Mimosa proposed a band plan for the 10.0-10.5 GHz band that would protect frequencies in the band that are most often used by Amateur Radio operators." The proposed band plan would specify 10.350 to 10.370 GHz as an "Amateur Calling Band," and 10.450 to 10.500 GHz for Amateur-Satellite operations in the midst of 21 wireless broadband channels and a small guard band.

Mimosa has proposed to include in the rules a requirement for wireless broadband service operation in the band "to avoid harmful interference with Amateur service and Amateur-Satellite service operations in the band."

Mimosa contended that its proposal would "promote the Commission's goal of providing broadband access to all Americans, would benefit wireless Internet service providers, mobile wireless carriers, and telecommunications equipment providers, and would benefit the national economy." Mimosa cited the band's "long-reach, high-capacity characteristics" and called 10 GHz "a promising candidate for wireless broadband."

ARRL Chief Executive Officer David Sumner, K1ZZ, said that while the League appreciates Mimosa's efforts to acknowledge existing and growing 10 GHz Amateur Radio activity, several aspects of the petition are of concern.

"Use of the band for fixed or mobile wireless broadband would be contrary to the international Table of Frequency Allocations and would inject a new sharing consideration that is not contemplated in the preparatory work being done for World Radiocommunication Conference 2015 (WRC-15)," he said. "Mimosa's proposed power limit of 55 dBW EIRP is very high, particularly for point-to-multipoint operations, and no mechanism has been proposed for ensuring that harmful interference to amateur operations does not occur."

Sumner said that while the ARRL has not yet adopted a position with respect to the petition, "some aspects of the petition require careful study."

Interested parties may comment on RM-11715 using the FCC's Electronic Comment Filing System (ECFS). Read more.

Public Service: National Hurricane Conference Announces Amateur Radio Sessions for 2014

Amateur Radio's role in responding to weather emergencies will be prominent during the National Hurricane Conference April 14-17 in Orlando, Florida.

Ham Radio in Space: Former NASA Astronaut Visits Missouri School as Kids Talk via Ham Radio with the ISS

Former NASA astronaut Linda Godwin, N5RAX, was on hand March 5 as youngsters at Rock Bridge Elementary School in Columbia, Missouri, spoke with NASA astronaut Mike Hopkins, KF5LJG, aboard the International Space Station (ISS). The Amateur Radio on the International Space Station (ARISS) program sponsored the contact. Hopkins, a native of Missouri who returned to Earth on March 10, was at the helm of NA1SS on the space station. On the ground, members of the Central Missouri Radio Association (CMRA), managed the technical aspects of bridging the gap between school and spacecraft. Once the contact got underway shortly before 8 AM, 13 pupils chosen through a random drawing each asked Hopkins two questions chosen from a prepared list.

"It's great to be talking with folks in my home state of Missouri," Hopkins greeted the gathering as contact was made and signal reports exchanged. Youngsters peppered him with questions on a wide array of space travel topics. "Zero gravity feels awesome!" he told the kids, although he conceded that it was "weird" at first. He said that viewing Earth from space was "humbling" as well as "incredible to see." He also explained some of the negative impact that living in microgravity can have on the human body over time, and he said that prior to going into space, the astronauts get to try and rate all food items on a scale of 1 to 10.

"The students understood that the ISS would be in range for less than 10 minutes," said the CMRA's Bill McFarland, N0AXZ, who played "the astronaut" during a pre-contact practice session. Also helping with the contact were club members Don Moore, KM0R -- who loaned his call sign to the enterprise and served as control operator -- Myron Kern, W0ZH, and Justin Yesis, KL0VU. They had been preparing for the event over the previous 6 months and provided the radio gear, rotators, antennas, mounting equipment, computers, and tracking software, as well as everything in between. The club also worked with NASA. Audio of the contact was piped into the school's public address system, so that the entire school could listen in on the 55 minute educational program built around the Amateur Radio contact.

After the pass, the elementary schoolers spent the next 35 minutes quizzing Godwin, also a Missouri native, who has four space shuttle missions and some space walks to her credit. She retired in 2010 and now is a professor of physics at the University of Missouri-Columbia,

Spearheading the entire project was Loretta Schouten, president of the Rock Bridge Elementary School's PTA. "She had the idea, presented the request to the CMRA, attended many of our club meetings, and coordinated everything from the school to NASA applications and documentation, local officials and the media," McFarland said. "And she is now studying for her Tech license!" The contact attracted coverage by the Columbia Daily Tribune newspaper.

ARISS lets students worldwide experience the excitement of talking directly with crew members of the International Space Station, inspiring their interest in science, technology, engineering, and math, and engaging them with radio science and technology. Contact ARRL ARISS Program Manager Debra Johnson, K1DMJ, if your school, local museum or other educational organization is interested in participating in a scheduled ARISS contact during the fall 2014/spring 2015 period. An educational plan describing the learning activities to be provided for the students leading up to and following the contact is necessary. There is more information about the ARISS program on the ARRL website.

Centennial: W1AW Centennial Operations Shift States on March 25; Station Reaches 100,000 Points in ARRL Centennial Challenge

The ARRL Centennial "W1AW WAS" operations that are taking place throughout 2014 from each of the 50 states now are in Tennessee (W1AW/4), New Mexico (W1AW/5), and Guam (W1AW/KH2). They will relocate at 0000 UTC on Wednesday, March 26 (the evening of March 25 in US time zones) to Iowa (W1AW/0) and Vermont (W1AW/1). During 2014 W1AW will be on the air from every state (at least twice) and most US territories, and it will be easy to work all states solely by contacting W1AW portable operations.

In conjunction with the 100th anniversary of the ARRL, the ARRL Centennial QSO Party kicked off January 1 for a year-long operating event in which participants can accumulate points and win awards. The Centennial QSO Party consists of two main activities: W1AW portable operations and the Centennial Points Challenge -- the accumulation of points from qualifying contacts. To have a score listed online in the Points Challenge competition, logs must be submitted through Logbook of the World (LoTW). The event is open to all, although only ARRL members and appointees, elected officials, HQ staff and W1AW are worth ARRL Centennial QSO Party points. Working W1AW/x from each state is worth 5 points per contact.

To earn the "Worked all States with W1AW Award," work W1AW operating portable from all 50 states. (For award credit, participants must work W1AW/1 in Connecticut.) A W1AW WAS certificate and plaque will be available (pricing not yet available).

The ARRL has posted an ARRL Centennial QSO Party leader board that participants can use to determine how many points they have accumulated in the Centennial QSO Party and in the W1AW WAS operations. Log in using your Logbook of the World (LoTW) user name and password, and your position will appear at the top of the leader boards. Results are updated daily, based on contacts entered into LoTW.

As of March 19, the W1AW stations have reported making more than 600,000 contacts with more than 70,000 different call signs. For the Centennial Points Challenge, based on uploads from these stations to LoTW, more than 5000 stations have achieved 1000 points, while 400 stations have reached the 10,000 point mark, 104 have 20,000 points, 49 have racked up 30,000 points, 15 stations have earned 40,000 points, eight stations (only one a single-operator, N2NL) have 50,000 points, and just one station has reached the 100,000 point mark.

On the Air: Michigan Ham Promoting Civilian Conservation Corps Special Event

Michigan radio amateur Dirk Esterline, KG8JK, is promoting participation in a Civilian Conservation Corps (CCC) Special Event this summer to honor the contributions of the Depression-era government-sponsored work program, and he hopes to make it an annual event. The CCC came into being in the spring of 1933, during the first term of President Franklin Roosevelt, as one of several economic relief programs during the Great Depression of the 1930s. CCC camps often were established in woodland areas, because the CCC was specifically tasked with environmental conservation.

"We want to honor the contribution that 'The Boys' of the Corps made to our country and to our natural environment," said Esterline. "As radio played a big part in how the camps communicated with each other, we would encourage you to activate the actual location of one of the camps." The special event will take place the weekend of August 9-10.

If an actual CCC site is not available, he pointed out, many state and local parks have buildings constructed by the CCC that might make suitable sites.

"Our goal is to make contacts between as many of the camps as possible, and to contact as many Amateur Radio operators as possible," Esterline said. He asks anyone interested in participating to contact him.

Milestones: Top Band DXer, Antenna Designer Charles E. Dewey Jr, W0CD, SK

Charles E. Dewey Jr, W0CD, of Battle Creek, Michigan, died March 16, at home. He was 96. Dewey, George Guerin, K8GG, and George Taft, W8UVZ, designed the "Battle Creek Special" antenna, popular with DXpeditioners. An ARRL Life Member, Dewey was a major 160 meter DXer, with 297 DXCC entities confirmed on Top Band (and an overall DXCC total of 367 -- 339 current -- needing only North Korea).

Charles Dewey Jr, W0CD

The Jefferson City, Missouri, native was first licensed as a teenager as W9LBM. He became interested in 160 meters in the 1970s, shunt feeding his 72 foot tower and laying down more than a mile of radials to work it against. He became a mentor to other Top Banders and, drawing upon his broadcast antenna expertise, designed various arrays for 160 meters.

He subsequently came up with an improved Battle Creek Special that was stronger, taller, and easier to erect and eventually developed a heavy-duty model that could handle high winds.

In 2012 the QCWA's Michigan Chapter 10 recognized Dewey for having been licensed continuously for 80 years. Read more. -- Thanks to George A. Guerin, K8GG, via The Daily DX

Feature: A Century of Amateur Radio and the ARRL

One very important, but lesser-known, advance in weaponry developed during World War II was the proximity fuze. Its cover name during the war years was the "variable time fuze" or VT fuze. Many of the engineers who developed the fuze were hams whom I knew during the post-war years, when I worked at the Applied Physics Laboratory of Johns Hopkins University. The following comments are from my conversations with two APL hams who played significant roles in the development of the VT fuze -- Lorry Fraser, W3LMZ, and Ralph Robinson, W5FDF.

When WW II began, anti-aircraft artillery fire was a game of chance. Rounds seldom made direct hits on aircraft. Modern aircraft of that day had a great advantage over the defense provided by AAA. The Navy needed a fuze that would detonate when it was close enough to attacking aircraft to cause major damage. Enter the VT fuze.

The concept of the VT was simple: Build a range-only radar small enough to fit inside the fuze of a 5 inch naval gun, and make it rugged enough to be fired from that gun. But it had to be done with components available in the early 1940s.

A cutaway view of a Variable Time Fuze.

APL found that ruggedized hearing aid vacuum tubes could be fired from a 5 inch Navy gun and survive. They designed a radar employing those tubes, which would detect the Doppler shift of the signal reflected from a target, determine when the shell was nearest the target, and trigger the explosive charge. Powering the VT fuze was a wet-cell battery without its electrolyte. When the round was fired, G forces would break an ampule of electrolyte, flooding the battery, and bringing it and the electronics to life.

After many months of development, tests, and trials, the VT fuze was ready for deployment. Robinson received a direct Navy commission, so he could deliver and put into action the first batch of fuzes. The Crosley Corporation was then chosen to manufacture VT fuzes on a production-line basis. VT fuzes had tipped the balance of power from attacking enemy aircraft to the Navy gunners, just in time.

The K7RA Solar Update

Tad Cook, K7RA, Seattle, Washington, reports: The vernal equinox is today! Both Northern and Southern hemispheres are bathed in an equal amount of solar radiation on March 20, as the sun is shining directly on the equator. This is a good season for HF propagation.

Average daily sunspot numbers decreased again this week -- from 138.7 to 129 on March 13-19, as compared to the previous 7 days. Average daily solar flux went from 149.7 to 141.4.

[SOHO image]

The latest 45 day forecast shows solar flux at 150 on March 20, 145 on March 21-22, 140 on March 23-24, 135 on March 25-26, then 145, 155 and 160 on March 27-29, 165 on March 30-31, 160 on April 1-2, 155 on April 3, and 150 on April 4-7. Flux values then dip to a low of 135 on April 12-16, and then rise to 165 on April 26-27.

Predicted planetary A index is 5 on March 20-23, 8 on March 24, 5 on March 25-29, 8 on March 30 through April 1, 5 on April 2-8, 10 on April 9, 5 on April 10-12, 8 on April 13-14, and 5 on April 15-25.

The entire 45 day flux forecast took a big jump on March 17. On March 16 the average solar flux for April was predicted to be 122.3. On March 17 and every day since, the average solar flux for April was predicted to be 149.8, an increase of more than 22 percent.

This weekly "Solar Update" in The ARRL Letter is a preview of the "Propagation Bulletin" issued each Friday. The latest bulletin and an archive of past propagation bulletins is on the ARRL website.

In tomorrow's bulletin look for an updated forecast, reports from readers, and scary news about a huge solar outburst in July 2012 that was similar to the infamous Carrington Event in 1859. The 2012 blast was aimed away from Earth, although it still crossed Earth's orbital path.
