Wow! Thank you so much, Andrew! I would love someday to operate an original RF4D.  What a fascinating WWII era radio. Thank you again for all of the details!

Post readers: I’m very curious if anyone here owns or has owned an RF4D.  Please comment!

It’s Field Day 2020 weekend during a pandemic and I see it as an opportunity!

This weekend is the 2020 ARRL Field Day!  Typically, I’d be telling you about the benefits of finding a local club’s Field Day site and getting on the air for the first time. This year?  Not so much.

2020 being a pandemic year, many clubs that would normally host a large public event are asking that either their members operate Field Day on their own–as individuals–or if they do host a public site, to practice social distancing and adhere to all local/state/provincial guidelines.

The 2020 setup is certainly a departure from the Field Day norm.

An opportunity

Field Day, at its core, is all about practicing radio preparedness. The contest classes and scoring are designed to promote battery/generator/solar power and even low-power (QRP) operations.

Field Day tends to be a group event and it certainly gives clubs a chance to coordinate and build an impromptu station with multiple operators.

But in a real emergency–say, a natural disaster that disrupts local transportation–responsibility would truly fall on an individual operator to get on the air from home and coordinate communications.

Use this Field Day as an opportunity to build a radio go-kit, to set up a portable antenna, operate from battery or generator power, and to see just how well you, as an operator, can cope with crowded radio conditions.

If you’re an SWL, Field Day is a perfect time to see just how well your receiver can cope in an RF-dense environment. If you want a challenge, try to see how many QSOs/exchanges you can monitor and log from as many sections as possible.

My Field Day plans

My trusty KX3 during one of my 90+ NPOTA activations.

This year, I plan to operate Field Day from a local National Park. I’ll set up a couple hours in advance of Field Day and activate the site for Parks On The Air (POTA).  When Field Day starts, I’ll abandon my POTA exchange and simply work stations as a Field Day site. I hope to play radio for at least a few hours or until afternoon thunderstorms chase me away. I plan to use both my Elecraft KX3 and Xiegu G90.

Being a radio reviewer, I always use Field Day as an opportunity to see how well a transceiver can handle adjacent signals. This year, I’ll be putting the G90 through its paces!

What are your plans?

Do you plan to operate on Field Day? Please comment with any plans you may have!

Pizzoloruss’s CityRadio: An Internet radio with a nostalgic & simple interface

Source: Wallpaper.com

Many thanks to SWLing Post contributor, Dennis Dura, who shares a link to this radio project by Emanuele Pizzolorusso who wishes to combine a modern Internet radio with old-school city-labeled memory buttons. From Wallpaper.com:

CityRadio, designed by Emanuele Pizzolorusso for Italian design brand Palomar, allows you to access local radio around the world, with a simple – and satisfying – click of a physical button. It’s a contemporary re-imagination of radio’s early history, where city names where displayed to identify frequencies. As travel looks to remain restricted for the time being, get your multicultural fix through the airwaves.

Of course, you can go online and access local radio anywhere fairly easily, but for Pizzolorusso, there’s a certain romanticism to, and interconnection with, the act of listening physical object. ‘In my childhood home there was an old portable radio, one of those appliances that had the names of several European cities on the tuning dials – a feature from the time when one could still listen to stations from foreign countries,’ explains the Italian designer, who is based in Helskinki. ‘The list of those places, which to me as a child appeared so mysterious and exotic, stimulated my imagination and gave that ordinary forgotten object a deep sense of magic.’

Press magnetic keys to access 18 different cities around the world – from Barcelona to Beijing, Nairobi to New York.[…]

Help Ed identify this mystery radio in “The Last Man on Earth”

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

Recently I’ve been watching some pandemic-themed movies and found “The Last Man on Earth”, a pretty good 1964 post-apocalyptic science fiction horror film (which was remade in 1971 and 2007 with different titles.) In this film, the main character (well played by Vincent
Price) uses an HF transceiver in a fruitless effort to find other survivors of a global plague. It was shot in Italy, and the transceiver doesn’t look like any American radio I’ve ever seen. Perhaps some of your SWLing Post readers can identify it?

BTW: SWLing Post readers might also be interested in knowing this film can be downloaded for free from The Internet Archive.  https://archive.org/details/lastmanonearth-1964

What do you say, SWLing Post Community? Is this radio a fabricated stage prop, or a real model?  Please comment!

In the meantime, I’ll add this post to our ever growing archive of radios in film!

Radio Waves: Deep ABC Cuts, Ham Radio Saves a Life, SDR Academy Updates, and a new free e-magazine from RASA

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 Michael Bird, Alexander von Obert, and the Southgate ARC for the following tips:


Up to 250 ABC jobs to go, ABC Life brand scrapped, flagship radio news bulletin dumped to tackle $84 million budget cut (ABC News)

The ABC will axe up to 250 jobs and cut programming as it deals with budget cuts of $84 million.

Managing director David Anderson said a flagship radio news bulletin would go, the ABC Life lifestyle portal would be rebranded, and programs would be reviewed as part of a major overhaul of the national broadcaster.

There will also be cuts to travel and to spending on television productions, as the organisation moves to become more relevant to more Australians and better reflect community diversity, he said.

Mr Anderson said the redundancies and savings would affect every division across the ABC.

“We anticipate we may farewell as many as 250 colleagues through this process,” he told staff in a briefing.

The News division is set to lose about 70 staff, the Entertainment and Specialist division 53 staff and the Regional and Local division 19.

Mr Anderson said there would be changes to executive staffing, but did not offer any details.

And he said the organisation would aim to have 75 per cent of its content-makers based outside its Sydney headquarters by 2025.

The ABC had already flagged that it would shed about 250 jobs due to a three-year funding indexation pause announced by the Federal Government in 2018.

Mr Anderson said the flagship 7:45am radio news bulletins would end, and be replaced by a five-minute bulletin at 8:00am. A 10-minute bulletin at 7:00am will remain.

The changes include:

  • ABC Life will become ABC Local and have a “broader editorial direction”
  • The travel budget will be cut by 25 per cent
  • Spending on external and independent television productions will be cut by $5 million a year
  • The ABC Comedy television channel will be rebranded to cater for a broader array of programs and content
  • Leasing of space at the ABC’s Sydney headquarters will be explored
  • TV and radio broadcast channels will remain, but transmission cuts have been flagged for future years[]

Ham Radio Saving A Life Locally! (Western Massachusetts ARRL)

On Tuesday, June 15, Alden Sumner Jones IV, KC1JWR, was hiking on the southern part of the Appalachian trail in Vermont (it’s also been reported as being on the Long Trail) with his cousins at around 12:30 PM. Alden started feeling light headed, his pulse was racing and the next thing he remembers is waking up with an EMT named Dave, from AMR out of Springfield, MA, who was hiking and saw Alden go down. Alden had suffered seizures. It was later determined that this was caused by low blood sugar. Dave attempted to call 911 on his cell phone. He could connect, but the 911 operator couldn’t understand him. At this point, Alden pulled out his HT ham radio, a BaoFeng.

He made contact through the K1FFK repeater. This repeater is located on Mt. Greylock on 146.91. The repeater is owned and maintained by the Northern Berkshire Amateur Radio Club. The initial call went out just before the Cycle 1 of the Western Massachusetts Traffic Net. Ron Wonderlick, AG1W, took the call. Alden initially asked if the 911 call went through. Ron began an eight hour process of acting as a relay between Alden, the emergency crews and various others.

The Traffic Net was truncated and the frequency was cleared by Peter Mattice, KD2JKV, who also stood by as a backup for Ron. KC1JPU, Matthew Sacco, was also monitoring and after a short consultation with Ron & Peter, proceeded to head to the staging area where the Fire and EMS crews were going to come from.[]

Software Defined Radio Academy 2020 Update (Markus Heller)

Dear ARRL recipients,

this year’s Software Defined Radio Academy is going to take place during the next weekend on June 27 / 28. We have now finalized the programme.

Since we decided very early in March that we’d organize an online strategy, we were not grounded by Corona. Using YouTube and our video conferencing system, we were able to organize a rich SDRA conference with speakers from all over the world.

Since this year’s European GNURadio Days conference in Besancon, France, could not take place either, we were asked to give their speakers a stage. This is the reason why we have a specially strong GNURadio focus.

With such a rich programme, we decided to span the talks over two days and start in the European afternoon, so that we could give our overseas audience a chance to participate live.

The mode is this: Even though all the talks are pre-recorded, the speakers will attend in the video conferencing system and respond to questions that come in through the YouTube channel. This way we can maintain a certain degree of interaction, which is important for any kind of scientific conference.

Here is the programme:
https://2020.sdra.io/pages/programme.html
and here is our YouTube stream URL:
https://youtube.sdra.io

We will start on Saturday 27 at 12:30 UTC+2
and on Sunday June 28 at 13:00 UTC+2.

For those of you who understand German, please note that this year’s HAMRADIO conference will also go online. We have worked hard in the past two months to record 65 hours of talks and discussions. Here is the HAMRADIO programme, which the SDRA is part of:
