ARRL Reply Comments Stress Need to Update Technician Privileges in a Digital World

In reply comments to the FCC (comments on comments already filed) on its Petition for Rule Making (RM-11828), ARRL has stressed that updating HF privileges for the entry-level Technician license “is the sole subject and intent” of the petition. ARRL filed its reply comments on April 29, urging the FCC to disregard comments irrelevant to its petition and maintaining that Technician privileges must be relevant within the context of today’s technological environment.

“[T]he increasingly rapid pace of change in communications technologies, coupled with the national need for self-training in science, technology, engineering, and math” necessitate the rule changes requested, ARRL asserted. “ARRL made its request because of the gap between today’s digital technologies and the privileges accorded the current entry-level Technician license.” ARRL characterized its proposal to update the rules as “balanced and modest.”

“If adopted, there would be no change to the operating privileges for all license classes other than those of the Technician class,” ARRL said. In 2018, ARRL asked the FCC to expand HF privileges for Technician licensees to include limited phone privileges on 75, 40, and 15 meters, plus RTTY and digital mode privileges on 80, 40, and 15 meters. The FCC invited comments on the proposal in April.

ARRL pointed out that some comments filed on its petition address subjects related to other open proceedings rather than expanding Technician privileges, citing comments cross-filed in such proceedings as WT Docket 16-239, RM-11708, RM-11759, and RM-11831. “Those filings should be considered in the proceedings that they address, rather than here,” ARRL said.

ARRL said some opposition appears based on fears of increased interference potential due to additional digital operation by Technicians. “It is improbable that all, or even a majority, of Technician licensees suddenly would develop a passion for the same digital technology,” ARRL said. “Our hope and expectation is that many will engage with digital modes on the high-frequency spectrum at issue, but it is unrealistic to suggest that every Technician licensee blessed with new privileges would suddenly appear on the same band.”

The comments note the development of very efficient digital modes, such as FT8, which occupies just 90 Hz of spectrum per signal. “The experience with FT8 clearly demonstrates the attraction of the digital modes and the spectrum efficiencies that can be achieved,” ARRL said. “This is why opening up limited digital opportunities to new radio amateurs so clearly would serve the broad public interest as well as the specific purposes of Amateur Radio in experimentation and innovation, as enumerated in the governing FCC rules.”

ARRL further said that comments regarding disagreement on the definition of encryption for masking the content of certain digital transmissions are also “out of place in this proceeding” and “should not delay initiation of a proceeding” proposing to update Technician privileges.

“Technology has changed dramatically in the Amateur Radio domain, and ARRL believes the requested Technician license enhancement would foster the regulatory goals for the Amateur Service and continue to increase amateurs’ historical experimentation and service in a meaningful way,” ARRL concluded.

World Scout Jamboree Gearing Up for Significant Amateur Radio Presence

Amateur Radio will be a part of this summer’s 24th World Scout Jamboree in West Virginia, the first World Jamboree held in North America since 1983. The Jamboree has chosen the theme “Unlock a New World.” Thousands of Scouts and Scout leaders from some 200 countries are expected to attend. The Jamboree’s Amateur Radio Exhibit will use the call sign NA1WJ — North America’s 1st World Jamboree. It will be on the air during the event, July 22 until August 2, at the Summit Bechtel Reserve, hosted by Canada, Mexico, and the US. Amateur Radio testing is expected to begin as early as July 14. Operating frequencies will be posted in real time via Facebook and Twitter or via an NA1WJ email group.

“The goals of the Amateur Radio station at the World Scout Jamboree are to introduce Amateur Radio to Scouts and Scout leaders through hands-on participation in two-way communication with other stations across the globe. This activity will also serve as the Amateur Radio voice of the Jamboree,” the World Scout Jamboree Amateur Radio Exhibit Operational Vision documentstates. Other facets of Amateur Radio at the Jamboree will include Amateur Radio direction finding (ARDF), Amateur Radio satellite contacts, and a scheduled Amateur Radio on the International Space Station (ARISS) contact with an ISS crew member.

“We also expect to launch one or two balloons with Amateur Radio payloads and track them as they cross the Atlantic,” the vision document continues.

Organizers are encouraging radio amateurs around the globe to get on the air during the World Jamboree to help NA1WJ demonstrate Amateur Radio for Jamboree visitors.

The 2019 World Scout Jamboree operation at the Summit Bechtel Scout Reserve will take advantage of lessons learned by the K2BSA Amateur Radio operation during the 2013 and 2017 USA National Jamborees. It will also take advantage of the existing infrastructure, which includes three VHF/UHF repeaters installed by Icom America, as well as the utility poles for installing antennas. K2BSA ham gear stored in West Virginia includes antennas, rotators, and cables.

Evening operation from NA1WJ will involve at least two operators using the buddy system. VHF/UHF repeaters will offer full coverage of the Jamboree area via handheld transceivers, facilitating networking as well as emergency communication. The exhibit will include an Amateur Radio station with the special event call sign W8J.

The demonstration station will include multiple operating positions offering a variety of modes. These include six stations with 100 W HF transceivers, computer logging software, and large screen computer displays; two VHF/UHF stations for demonstrations and repeater monitoring, and two satellite communication systems. The antenna farm will include two HF directional antennas, three HF dipoles, three HF vertical antennas, VHF/UHF verticals and satellite antennas with azimuth and elevation control, a trailer-based crank-up tower, a five-band Yagi, a 40-meter rotatable dipole, and a 6-meter Yagi.

Each station will be able to accommodate four participants at a time, plus one control operator. The goal is to give each participant up to about 10 minutes of operating time.

The K2BSA Amateur Radio Association will host a “Radio Scouting” booth at Dayton Hamvention® (Booth 2205 in Building 2).

Science and Technology: An Ultra-Small Transmitter for VLF?

A study, “A high Q piezoelectric resonator as a portable VLF transmitter,” by Stanford University SLAC National Accelerator Laboratory researcher Mark A. Kemp et al., in the April 12, 2019, edition of Nature Communications describes using a small rod of lithium niobate and taking advantage of the material’s piezoelectric properties to convert an imposed voltage to a mechanical effect, which in turn radiates an electromagnetic current.

The National Accelerator Lab describes the research in an article, “SLAC develops novel compact antenna for communicating where radios fail,” which said a new type of pocket-sized devices “could be used in portable transmitters for rescue missions and other challenging applications demanding high mobility” where conventional radios don’t work, such as under water, through the ground, and over very long distances through air. “The device emits VLF radiation with wavelengths of tens to hundreds of miles. These waves travel long distances beyond the horizon and can penetrate environments that would block radio waves with shorter wavelengths.”

“Our device is also hundreds of times more efficient and can transmit data faster than previous devices of comparable size,” Kemp, the project’s principal investigator. “Its performance pushes the limits of what’s technologically possible and puts portable VLF applications, like sending short text messages in challenging situations, within reach.”

The paper by Kemp et al. points to the fact that large size and high loss render conventional transmitter techniques inadequate. “We show that a strain-based, piezoelectric transmitter can overcome many of the fundamental limitations of conventional electrically small antennas (ESA),” the paper’s abstract reads. “These transmitters can resonate in a very small footprint while exhibiting low losses.”

Taking a deeper dive: “Traditionally, a disadvantage of passive high-Q antennas was low bandwidth. Utilizing piezoelectricity as the radiating element allows us to dynamically shift the transmitter resonant frequency. Therefore, high total Q (low loss) no longer constrains the system bandwidth. These are our fundamental advancements: Achieving an exceptionally high system Q with no external impedance matching network and an effective fractional bandwidth beyond the passive Bode-Fano limit. Although demonstrated at VLF, this concept straightforwardly scales to other frequency bands.”

ARRL’s Free Exam Review for Ham Radio Updated

ARRL Exam Review for Ham Radio has been updated in advance of the release of the ninth edition of The ARRL General Class License Manual for Ham Radio. ARRL Exam Review is a free online resource for use with current editions of ARRL License Manuals. The service can be accessed via a web browser, and uses the official examination question pools to construct chapter-by-chapter reviews. Upon completing study, Exam Review helps the license candidate take practice exams with the same number and variety of questions that he or she will encounter on exam day. Practice tests can be taken over and over, scored in complete privacy, or even printed with an answer key. Exam Review includes quick feedback about the questions missed.

The update to Exam Review and the new edition General Class License Manual coincides with a new General Class question pool released earlier this year by the National Conference of Volunteer Examiner Coordinators (NCVEC). The new 2019 – 2023 General Class question pool becomes effective on July 1, 2019 for examinations in the Amateur Radio Service. The 2015 – 2019 General Class pool remains in effect for exams given until June 30, 2019. ARRL Exam Review provides access to both the current and new General Class questions. (Read more.)

Annual Armed Forces Day Crossband Test Set for May 11

The Army Military Auxiliary Radio System (MARS) will host the traditional military/Amateur Radio communication tests to mark the 68th annual Armed Forces Day (AFD) on Saturday, May 11. The event is open to all radio amateurs. Armed Forces Day is May 18, but the AFD Crossband Military-Amateur Radio event traditionally takes place 1 week earlier in order to avoid conflicting with Dayton Hamvention®. Complete information, including military stations, modes, and frequencies, is available on the US Army MARS website.

“For more than 50 years, military and amateur stations have taken part in this event, which is only an exercise scenario, designed to include hobbyist and government radio operators alike,” the event announcement said. “The AFD Crossband Test is a unique opportunity to test two-way communications between military communicators and radio stations in the Amateur Radio Service, as authorized in 47 CFR 97.111. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly-controlled exercise scenario that does not impact any public or private communications.”

During the event, military stations in various locations will transmit on selected military frequencies and announce the specific ham frequencies they are monitoring.

Military stations expected to be on the air for the event include those in Arizona, Japan, Hawaii, Okinawa, Washington, DC (and elsewhere in the contiguous states), the USS Midway, the USS Yorktown, the USS Iowa, LST-325, the US Naval Academy in Annapolis, and the Newport Naval Radio Station Museum in Rhode Island. The MARSCOMM and MARSRADIO nationwide networks will have multiple stations on the air across the continental US.

An AFD message will be transmitted utilizing the Military Standard (MIL-STD) serial PSK waveform (M110) followed by MIL-STD Wide Shift FSK (850 Hz RTTY), as described in MIL-STD 188-110A/B.Technical information is available. The AFD message will also be sent in CW and RTTY, as indicated on the full schedule. Anyone wanting a QSL should complete the request form on the MARS website.

In Brief…

School Club Roundup (SCR) certificates are now available for the February 2019 event as well as for any future SCRs. Download these via the Certificate menu item on the ARRL Contests Portal. Top US/Canada performers included the Russell Elementary Amateur Radio Club (KM4RE) in the Elementary/Primary category; Schofield Middle School Ham Radio Club (N4SMS) in Middle/Intermediate/Junior High category; LASA High School Amateur Radio Club (K5LBJ) in the Senior High category, and Purdue University (W9YB) in the College/University category. Complete results are on the School Club Roundup Results page.

Some 50 students in Gujarat, India, on April 12 were introduced to Amateur Radio, satellites, and Amateur Radio on the International Space Station (ARISS). Rajesh Vagadia, VU2EXP, gave a brief talk on Amateur Radio, the ISS, ham satellites, astronauts, and the April ARISS SSTV event. During a visible pass of the ISS, Vagadia, using a three-element Yagi, handheld transceiver, and a recording device, was able to record two SSTV images. “It was an exciting experience for all, sighting the ISS, and at the same time getting signals from it,” Vagadia commented afterward. “[It] felt like having a handshake with the ISS crew!” Decoded images were shared with all students as souvenirs.
