ARRL: “Remotely Administered Amateur Exam Systems Showing Promise”

(Source: ARRL News)

Facing a growing demand for amateur radio exam sessions in a time of social distancing and stay-at-home orders, sponsors of some Volunteer Examiner (VE) teams have risen to the challenge and are developing systems to remotely proctor test sessions.

“Many of our VEs and VE Teams have been working on remotely proctored exam session ideas, employing both video and in-person components — following social distancing protocols,” ARRL Volunteer Examiner Coordinator (VEC) Manager Maria Somma, AB1FM, said. “We have been receiving interesting and innovative suggestions, and we appreciate the dedication and ingenuity our examiners have shown.”

The Spalding County Amateur Radio Club in Georgia is among those that have come up with plans to remotely administer amateur exams while complying with ARRL VEC testing standards during COVID-19 stay-home mandates and social distancing guidelines. Current systems leverage Zoom video-teleconferencing technology, the “Fill & Sign” feature of Adobe PDFs, reliable email, appropriate computer equipment and internet connection, and no volunteer examiners (VEs) present at individual remote test sites. The Georgia club collaborated and shared ideas with the Emergency Amateur Radio Club (EARC) in Hawaii, which has successfully conducted sessions since 2011 with its own remote testing system, initially with paper exams with a proctor on site and now with fillable PDFs, with no on-site proctor.

The Georgia club obtained ARRL VEC approval to administer video-supervised exams. The club’s David Robinson, K4WVZ, said the first exam session took place this week, with another set for next week, and “many more in the pipeline” going forward.

“We have started with testing just one candidate at a time but are planning to ramp up to multiple candidates — probably two or three — simultaneously,” Robinson told ARRL. “Before we do that, we want a few more single sessions under our belt and a few more Video VEs trained. It also gives us an opportunity to garner lessons learned from each test session and upgrade our procedures accordingly.” Robinson said this week’s session went “exceedingly well,” and the candidate passed the test.

The club’s procedures entail a pre-exam video interview with candidates to ensure they understand all the requirements and procedures. “This also allows us to test the candidate’s ability to work with the video and computer technology before the actual exam,” Robinson explained. “Training sessions were conducted for VEs to make sure they understood their role and how to use the technology.”

Following the exam, the VEs score the test and sign off on the paperwork, with the VE Team Leader submitting the application online and by mail, per ARRL VEC instructions. Application and successful exam are first accepted and then submitted to the FCC for processing.

New England Amateur Radio Inc (NE1AR), an affiliate of New England Sci-Tech, (NESciTech), has taken it one step further, Somma said. It got the approval of ARRL VEC to begin trials of what it describes as “completely online testing with strict rules and protocols for maintaining the integrity of the testing environment.” NE1AR is limiting candidates to one exam per candidate, due to the current candidate backlog and the “difficulty of administering exams online.” Candidates must agree to a list of protocols, which include no visitors (or pets) in the exam room and a cell-phone camera scan of the entire room and exam area “to show that there are no materials or people [in the room] that could aid in taking the exam.” If the VE team suspects the possibility of cheating, the exam may be terminated and the candidate barred from future online exam sessions.

“We began a series of trials on April 1 under ARRL VEC review and have now been asked to help train more VE Teams on the process,” NE1AR President Bob Phinney, K5TEC, told ARRL. “We have now tested 12 applicants and are still working on streamlining the process. We are working with the software developer of the exam delivery system to help them adapt the system for video-supervised testing.” At present, Phinney said, only one person at a time can be tested. Another time-related issue is how long it takes a candidate to go through the NE1AR security protocol. “Sometimes, the setup and follow-up for an exam take far longer than the exam itself, in order that we provide complete integrity of the exam session,” he said.

With pressure continuing to build to provide testing compatible with COVID-19 guidelines and stay-home orders, ARRL VEC Manager Maria Somma, AB1FM, has asked the amateur radio community to be patient. “Please remember that with the introduction of significant new processes such as these, that there should be proof of concept, establishment of protocols and procedures, and beta testing, before expanding to a larger audience,” she said this week. Somma said video-supervised exam sessions require a different skillset than in-person exam administration, and not all teams will be equipped to deliver video exams right away.

“ARRL is pleased to be one of the leaders in providing an opportunity, although limited initially, for video-supervised exams in this time of social distancing and isolation required by the current health situation,” Somma said.

“National Press Club and Journalism Institute support VOA and its journalism”

(Source: National Press Club Press Release)

WASHINGTONApril 16, 2020 /PRNewswire/ — The National Press Club and the National Press Club Journalism Institute stand with Voice of America and its director, Amanda Bennett, against unsupported criticism by the White House of its coronavirus coverage.

Bennett is a highly respected journalist who has been a staunch advocate of the independence guaranteed in The VOA Charter signed by President Gerald R. Ford in 1976. To claim, as the White House has done, that VOA has been reporting Chinese propaganda flies in the face of the facts. VOA has reported on the Chinese undercount of coronavirus deaths in the city of Wuhan, reported on China’s misleading count of cases testing positive and reported on China’s use of Twitter to spread disinformation globally.

“From its founding during World War II to combat Nazi propaganda with accurate and unbiased information, the Voice of America has consistently served the world in a manner in which all Americans can and should be proud,” said National Press Club President Michael Freedman. “From Edward R. Murrow to Amanda Bennett, VOA has represented the best in journalism and we stand firmly behind its reporters, who are dedicated to truth and accuracy.”

“The attacks from the president and from White House officials not only undermine VOA’s mission, but they pierce a firewall that is supposed to protect the publicly financed news agency from political interference,” said NPC Journalism Institute President Angela Greiling Keane.

When Amanda Bennett was honored with the National Press Club’s Fourth Estate Award last year, she said: “Here’s what we do do: We broadcast all around the world the uncensored version of speeches. The unheard views of opposition parties. The stories of disappeared teachers, politicians, journalists – sometimes even whole populations. And we also show the world America in all its — yes, greatness – and also its flaws and faults. We are as independent as all of you are, and – again – God willing, we stay that way. As we say, we broadcast the First Amendment.”

The National Press Club, The World’s Leading Professional Organization for Journalists™, represents more than 3,000 reporters, editors and professional communicators worldwide. The Club’s nonprofit affiliate, the National Press Club Journalism Institute, promotes an engaged global citizenry through an independent and free press, and equips journalists with skills and standards to inform the public in ways that inspire civic engagement.

Ham Radio Friedrichshafen 2020 has been cancelled

Many thanks to SWLing Post contributor, Harald Kuhl, who shares the following announcement from Ham Radio Friedrichshafen:

Radio silence due to coronavirus COVID-19: Ham Radio not taking place as planned
15.04.2020

Friedrichshafen – Due to current developments in regard to the spread of coronavirus COVID-19, Messe Friedrichshafen has been forced to make a very difficult decision: the international amateur radio exhibition Ham Radio will not be taking place in the planned period of June 26 to 28, 2020, but instead from June 25 to 27, 2021. The Federal Government and the Minister-Presidents of the Länder decided yesterday, April 15 that no major events shall take place until August 31, 2020.

“Due to current developments relating to the coronavirus, we have the unfortunate duty of announcing that we cannot hold the 45th edition of Ham Radio as planned,” explains Klaus Wellmann, Managing Director of Messe Friedrichshafen. In recent weeks, it was already necessary to make the same decision in regard to other events (Aqua-Fisch, IBO, AERO, Tuning World Bodensee, and Motorworld Classics Bodensee). Project Manager Petra Rathgeber also expressed her sadness about this turn of events: “We very much regret that this event cannot take place as planned. However, the health of all exhibitors and visitors is of utmost importance to us. Unfortunately, our trade fair calendar and the dates of other industry events leave no room for postponing this fair to another date this year.” Christian Entsfellner, Chair of the German Amateur Radio Club (DARC), adds: “Our members, domestic and foreign guests, and we ourselves have been hit hard by this decision, which now became necessary to make on short notice. Until we get together again in Friedrichshafen, we as amateur radio operators are looking forward to keeping in contact with one another using amateur radio.” However, radio amateurs do not have to do without everything the Ham Radio fair normally has to offer: On the Ham Radio website, exhibitors will be presenting product innovations in the form of a virtual trade fair. DARC will also be offering presentations there.

The exhibitors, visitors, and partners involved are currently being informed about this opportunity.

Thank you for sharing this, Harald! Not a surprising development, but sad nonetheless. I assume Covid-19 might also lead to the closure of Ham Fair 2020 in Tokyo.

myNoise: possibly the best ambient sound generator on the planet

My wife has an amazing ability: when she’s deep into research, writing, editing, or creating something, she has a laser-focus like none other: she can tune out the world around her to the point that it’s honestly hard to get her attention. She can work in almost any environment, and tune out (nearly!) all distractions. It’s quite impressive. She credits this ability to focus in distracting surroundings to our children, who at a young age developed the less-rare ability to generate noise, both wide in variety and sometimes quite intense in volume.

Me? Completely the opposite.

When I’m writing or working on a project––indeed, whenever I need to concentrate––I either have to work in a controlled environment where I have few interruptions, or I have to artificially create that controlled environment.  I usually do this through the use of an ambient noise or instrumental (non-vocal) music. It’s rare that I’m working in an environment with no interruptions, so being able to manufacture my own audio space is important for my productivity.

When I’m here at SWLing Post HQ, I’ll often tune to an HF frequency that has no signal occupying the space. In other words, I’ll listen to shortwave radio static that might include the odd ionosonde sweep and occasional static crash….it creates a white noise that, in essence, nulls out everything else around me. Plus, as a radio geek, I confess to feeling quite at home in that static.

To help me catch some zzzs when I travel, I’ll often do the same: simply tuning to an unoccupied HF frequency and letting it play through the night. I find that it nulls out hotel hallway traffic, like doors banging and loud talking, allowing me to get some needed rest.

I also turn to noise generators and numerous YouTube channels that specialize in long ambient field recordings, because finding a reliable (unoccupied) radio frequency doesn’t always work due to garrulous local radio interference or simply a lack of free space on the FM band.

Introducing myNoise

This year at the Winter SWL Fest my friend, David Goren, recommended a website––and accompanying application––called MyNoise.net. As an audio engineer and radio producer, David has a finely-tuned ear and can notice looped sounds, audio irregularities, and poorly-made recordings. So I knew if David Goren was impressed with this collection of ambient noises, they would be first-class.

MyNoise.net is the product of Dr. Stephane Pigeon, a man with an impressive CV that includes consultant work for Roland Corporation and numerous audio websites and applications.

What makes his site so unique is: 1) the sheer number and variety of ambient soundscapes, and 2) the ability to finely-tune and customize each sound in a remarkable number of ways.

Want to travel to a pebble beach, a primeval forest, a Japanese garden, or fall asleep on the bridge of a starship? Yeah, you’re covered––really. And not with, as is typical, short hiccuping loops with background muck imbedded: the MyNoise collection (at time of this post) contains over 200 customizable sound generators, with lengthy live field recordings, and they’re clean. The real deal…high fidelity at its best.

If you like ambient audio, his site provides an incredibly rich deep-dive…

But don’t take my word for it.  Listen for yourself!

Radio Soundscapes

myNoise slider controls allow you to change the level of audio tracks and loops.

When David first introduced me to myNoise, he pointed out two soundscapes in particular: one was called “Shortwaves,” the other, “Numbers Stations.” (Now that’s what I’m talking about!) Every night of the SWL Fest, I listened to these two noise machines as I slept. It was wonderful.

With permission, I have made a couple one-minute audio recordings of the two radio-specific soundscapes from myNoise.net. Keep in mind that these recordings were set at a preset level and left alone; in other words, I did not move the control sliders during the recording. In reality, the sounds can be tailored to your listening pleasure via the sliders and generous array of controls. By the way, I suggest wearing headphones.

Sample of “Shortwaves”

Sample of “Numbers Stations”

While I love these two radio sound generators, I have to say, I’ve truly enjoyed exploring the more than 200 sound generators also available on myNoise.

How to listen

MyNoise.net is a free website supported by user donations.  (Donations, by the way, can unlock an array of extra features and sounds.) Even though I have the app (see below), I still sent a bit of extra support though their website; after all, this is just the sort of project I love supporting.

MyNoise is also available as an iOS or Android app. If you have a mobile device or tablet, I highly recommend downloading the app and purchasing the full set of recordings for a mere $10.

Stephane also has a YouTube Channel with a number of soundscapes.

Hack a broken VGA cable to make a binocular ferrite cores for your NCPL antenna

Many thanks to Oscar (EA3IBC) who shares this simple hack.

I’ve gotten quite a few emails from Post readers telling me that the only thing holding them back from building a NCPL antenna is the BN-73-302 binocular ferrite core needed for the 1:1 Balun. While so much of the world is sheltering at home due to Covid-19, it’s less convenient to purchase one just for this purpose.

But almost everyone has an old VGA or USB cable with ferrite cores they can cannibalize for this  very purpose. Oscar shared this super-simple hack on Twitter:

1. Cut the cable and remove the ferrite cores

2. Tape the two cores together

3. And wind four turns on both sides

Admittedly, this 1:1 balun might not have the same properties as the BN-73-302 from our tutorial, but it seems to be working for Oscar. Check out this screenshot he shared from SDR# while hooked up to his NCPL antenna:

Thanks again!

DRM featured on BBC Digital Planet

DRM broadcast (left) as seen via a KiwiSDR spectrum display.

Many thanks to SWLing Post contributor, Ed, who writes:

The April 14, 2020 edition of the BBC World Service program ‘Digital Planet’ includes a story about the status of Digital Radio Mondiale (DRM) broadcasts on shortwave. The segment had no breaking news, but SWLing Post readers might enjoy hearing an updated explanation on BBC of how DRM works on shortwave and other bands, where it’s being used, and what unique services it can offer. The segment includes a clip of digital audio played over shortwave and an interview with Ruxandra Obreja, Chair of the DRM Consortium and DRM Association.

The segment was followed by a casual conversation between BBC producer Gareth Mitchell M7GJM and interviewer Bill Thompson about SWLing and Amateur Radio–which was great to hear discussed on BBC World Service!

The entire segment and followup discussion begins at 21:17 and ends at 31:49 minutes into the mp3 recording found at this BBC URL:

Thank you for the tip, Ed! Digital Planet is a fantastic technology show–check out more episodes on their website.
