Amateur Radio Association of Nebraska 3D print face shields for healthcare workers

Many thanks to the Southgate ARC for sharing this brilliant story.  Kudos to the Amateur Radio Association of Nebraska for their ingenuity in time of need:

KSNB TV News reports on an Amateur Radio group that is pitching in to make face shields for healthcare workers

The news story says:

With a national shortage of personal protective equipment for healthcare workers, people are doing what they can to fulfill the orders. When they heard of the need, some members of the Amateur Radio Association of Nebraska looked at each other and found a way they could help. Now with people outside of the group helping, too, they are using 3D printers to create face shields.

Their 3D printers have been running all day for over a week now. Volunteers across the Tri-Cities are quickly making face shields for hospitals and clinics who need to serve the public. The shield is a simple frame design with a plastic cover. The cover can be quickly changed out or reused.

“Material-wise we have pennies on the dollar for these things so we want to make sure our healthcare workers and everybody involved in the field are safe and so we’re doing what we can to help,” Amateur Radio Assoc. President Allen Harpham WD0DXD said.

The frames are printed, but the shield part is actually recycled overhead projector sheets from schools. They have gotten thousands of sheets donated to them from schools in central Nebraska who have no other use for them anymore.

Amateur radio fans also often have their hands in other kinds of tech.
So that’s why the idea came so easy to them.

“To be able to put that knowledge to use to help out is just great,” Harpham said. “I can’t say enough about that and it’s kind of the way for the amateur radio people that’s the way we’ve always been.”

Radio Waves: New FCC RF Exposure Limits, Rediscovering Spark Gap, Zoom Vulnerabilities, and Extremely Rare Film of MI6 Section VIII

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Paul Evans, and Robert Gulley for the following tips:


FCC Publishes new RF exposure rules (Federal Register)

The FCC has published the new rules in the Federal Register.

Paul notes:

Different above 6GHz
Expanding rules from 3 kHz – 300 GHz to 3 kHz – 3 THz (inc. light
frequency RF sources, essentially future proofing rules)
Introducing SAR measurements from 100 kHz to 6 GHz (impact to ARS)
Introducing MPE measurements above 6 GHz
Introducing ideas for WPT at and below 100 kHz, with control over the
wires or remotely over the air. This is (obviously) for EV charging.
They say nothing about harmonics, filtering, etc.[]

We Rediscover Spark Gap Radio by Accident (CuriousMarc via YouTube)

It’s 1890 all over again in the lab. By complete accident, I find myself the new owner of a high voltage box that turns out to be a vintage Xenon lamp sparker. Not only do we make it work, but we use it to retrace the critical experiments that led to the discovery of radio, using the lamp starter as the spark gap transmitter, and a coherer as the receiver.[..]

Zoom taking your club online – DON’T (Southgate ARC)

On Friday 3rd April, we carried an item regarding the use of Zoom for club meetings.

However, we have since been contacted by Paul, VP9KF, who offers this note of caution.

He says:
“This story http://www.southgatearc.org/news/2020/april/zoom-taking-your-radio-club-online.htm on your page recently is over-shadowed by the news as follows:

https://www.theguardian.com/technology/2020/apr/02/zoom-technology-security-coronavirus-video-conferencing

Don’t use Zoom and get hacked ”

Our thanks to Paul for this informative, if not rather worrying, news item.

WW2 Codebreakers: Bletchley Park activities revealed in unique footage – The Hidden Film (YouTube)

Discover the story behind the recently discovered only known wartime film footage of a secret site connected to Bletchley Park.

A silent film, recently donated to Bletchley Park Trust, is believed to be a compilation of footage recorded between 1939 – 1945, showing members of MI6 Section VIII at Whaddon Hall, Buckinghamshire. During World War Two, this was a most secret site where Ultra intelligence produced by the Government Code and Cypher School (GC&CS) at Bletchley Park would be sent, and then passed on to Allied commanders in the field.

In this mini-documentary, hear Bletchley Park Veteran, Geoffery Pidgeon who worked in MI6 Section VIII during WW2, recall how it felt to watch the film for the first time and recognise his father. Peronel Craddock, Bletchley Park’s Head of Collections and Exhibitions and Dr. David Kenyon, Research Historian at Bletchley Park also talk about why the discovery of this film is so important.

A trusted companion: The Panasonic RF-2200 never lets me down

One of the great things about sheltering at home during the Covid-19 pandemic, is I have time to complete some projects that would have otherwise waited until much later this year.

Lately, I’ve been making a serious effort to have our firewood cut, split and stacked so that it’ll have time to cure and dry before winter.

I’ve got a load of wood in my truck to process today so decided to take the Panasonic RF-2200 outside and do a little AM BC listening to make the splitting session pass a little faster.

The Panny ‘2200 is ideally suited for this task: it has robust sound and is one of the best AM DX portables ever made. I knew it would easily lock on to WTZQ 1600 kHz (some 25 miles away).

But as I sat the ‘2200 on the tailgate of my truck, I noticed that the power switch was already on!

My heart sank. The last time I had the RF-2200 out was well over a week ago and I was certain I had no D cells charged and ready to replace these.

But then I turned up the volume and there was static. I tuned to WTZQ and it sounded like it was one mile down the road. I turned up the volume a bit more when I heard Homeward Bound by Simon & Garfunkel.

Turns out, there was a lot of battery life left. The Panny ‘2200 never let’s me down.

The Panasonic RF-2200 is a Holy Grail Radio. Plain and simple.

Do you have an RF-2200?  Please comment!

Icom IC-705 delivery has been delayed

Many thanks to SWLing Post contributor, Paul Evans, who writes:

As you’d expect, Icom has formally delayed the delivery schedule of the IC-705.

Here’s the announcement from Icom Japan: https://www.icom.co.jp/news/4720/

The following is a machine translation of the announcement:

“Thank you very much for your patronage of ICOM products.

We have received reservations from a large number of customers about the IC-705, a 10W walkie-talkie with HF~430MHz all-mode, which was scheduled to be released in late March 2020. Some of the parts involved in the production of the product are delayed due to the new coronavirus issue, and production has been delayed due to this.

We apologize for any inconvenience caused to all of you who are looking forward to our products.

As for the delivery of the product, because it is a situation in which the arrival schedule of the part does not stand now, I will guide it separately as soon as it turns out.

We will take a while to deliver it, but we will do our best to deliver it as soon as possible, so please understand us.”

Thanks for sharing this, Paul. No doubt, delays are due to the affects of Covid-19 on both manufacturing in Japan and throughout the IC-705 supply chain.

For updates, bookmark the tag IC-705.

Radio Waves: LPFMs Go Non-Directional, ABC Cuts Remain, WBCQ Videos, and Demolition of Hara Arena

Hara Arena during the 2016 Dayton HamventionRadio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Ulis (K3LU), Michael Bird, and Trevor Dailey for the following tips:


New FCC Rules Would Allow LPFMs To Use Non-Directional Antennas. (Inside Radio)

The FCC is scheduled to vote on controversial new rules that would potentially end a prohibition on low-power FM stations using directional antennas, among other things. At its April Open Commission Meeting, the agency will vote on a Report and Order to update its technical rules for LPFM stations.

Since the Local Community Radio Act of 2010 was passed nearly a decade ago, the number of LPFMs has grown to more than 2,100 stations. The LPFM service has “matured since engineering requirements were first established in 2000,” FCC Chair Ajit Pai said in a blog post announcing the April meeting agenda. “This maturation means that LPFM stations should be able to take advantage of additional engineering options to improve reception.”

In addition to improving reception, the proposed new rules would “increase flexibility while maintaining interference protection and the core LPFM goals of diversity and localism,” Pai said.

Along with expanded LPFM use of directional antennas, the proposal would allow LPFM stations to use FM booster stations.[]

The ABC is an essential service but funding cuts remain, says boss (The Age)

The ABC could have to look at closing a channel if the government remains committed to the funding cuts announced in the 2018 federal budget, according to managing director David Anderson.

“We don’t think we can bridge the gap purely from efficiency alone,” said Mr Anderson on Thursday, as the broadcaster revealed a suite of programming that it hopes will help Australians through the next three months of social isolation.

“That’s where you start to look at what it is you’re providing on what service. At the moment we have no plans to turn off a channel or a network, but I have to say that in the foreseeable future turning off a channel will happen one day. It’s just not right now.”

The ABC is in the second year of its current triennial funding round, in which the government declined to index its base funding, effectively meaning its budget has been cut by $84 million over the three years to 30 June, 2022.[]

Demolition of most of Hara Arena will start soon (Dayton Daily News)

Michael Heitz, the developer of the Hara Arena property, said Monday that sometime in the next two to three months, demolition of about two-thirds of the tornado-damaged property should begin.

Heitz said he is putting together a legal description of the recently rezoned former entertainment property, with an environmental report and surveys, for JobsOhio. He expects JobsOhio, the state’s private jobs creation arm, to put its marketing muscle behind the 130-acre site, to help him find a future user.

“This is one of their biggest tracts in the state of Ohio, under one piece of land,” Heitz said in an interview. []
