BBC Radio Stations Broadcasting Re-Tune Instructions

Many thanks to SWLing Post contributor, Bill Hemphill (WD9EQD), who writes:

Hi Thomas,

The BBC in their transition to digital radio has started closing some of their AM radio stations.

See following link:

https://www.bbc.co.uk/reception/work-warning/news/mw-closures-2021

The AM stations being closed are broadcasting “Re-Tune” instructions on their frequencies.

Not sure how long they will be doing this. The “Re-Tune” messages are interesting.

I have used the G4DYA KiwiSDR web receiver to listen and record some of the “Re-Tune” messages.

Most are just straight forward instructions, but Radio Hereford-Worcester on 738 has recorded individual

messages by several of their on-air personalities. The messages just loop continuously.

Attached are MP3 files for 738 Radio Hereford-Worcester, 1035 Radio Sheffield, 1341 Radio Ulster and 1503 Radio Stoke.

CQ CQ CQ IE —Holy Broadcasting from Ireland and Northern Ireland (DXing.info)

European DX listeners have recently discovered a wonderful new target. On 27 MHz it is possible to receive Catholic mass celebrations from Ireland and Northern Ireland. Hundreds of local churches around the island are broadcasting holy masses live. If you tune in between 27000 and 28000 kHz, you might be able to hear many interesting churches. The transmitter power is usually only 3 watts, so a strong F2 opening is needed. Luckily with the current solar maximum this happens quite often.

How did all this start? This is a fascinating story, told by a Father, who has been helping the idea to become reality.

The broadcasting of Masses was introduced in a rural Irish diocese over 30 years ago when the resident priest was considering a way of reaching out to those who were housebound in his parish. They had access to religious broadcasts on National Radio and TV, but he knew that it was no comparison to a local broadcast. There were many incidents of families coming home from Mass on Sunday and their housebound parent or grandparent had ‘all the news’ (they were aware of all the happenings in the parish) when they arrived home.[…]

Utica man producing film about the history of radio (The Voice)

Decades before Spotify, Pandora, and even satellite radio, terrestrial (land-based) AM and FM radio reigned supreme. Many listeners, including Utica resident Ron Robinson, idolized the disc jockeys just as much as the artists they played.

Robinson, 51, is working on a documentary film entitled “Radio Dayz… The Movie,” which focuses on the history of radio, including the early days of Detroit radio. “(The film) tells the story of radio through the people who worked in radio,” he said.

Robinson interviewed several well-known radio personalities such as Paul W. Smith, Dick Purtain, Fred Jacobs, Dick Kernen, and more for the film. Robinson, who worked for WJR for 20 years before starting his own production company, has several connections in the industry. He started interviewing for the documentary in 2013.

“Most people think of radio, they think of New York, California, and Chicago, and rightfully so. But, Detroit has been an important and ground-breaking city for the medium of radio,” Robinson said.

The documentary is a chronological look at the history of radio, starting with the first radio stations. It also takes aim at the first radio “celebrity,” Fr. Charles Coughlin. The Detroit-area priest took to the airways in the 1920s and eventually garnered an audience of 30 million to his weekly radio show. Coughlin would later become a polarizing figure as World War II approached. “He’s on the wrong side of history, if you will,” Robinson said.

Improving ULR FM reception (Iberia DX)

Often I get surprised when I listen to the FM Band with my autoradio. It has no bandwidth options, no filters, but sensitivity and selectivity are much better than most of the well-know portables. Mine is inserted into the Skoda console so I have no way to know who manufactured it, the brand/model or its tech specifications. Most of the times I wonder why other portable firmwares does not include, for instance, similar choices like the high speed decoding RDS info. Then I thought… Will be my ULR Sangean DT-800 up to the task?

An autoradio like mine (SKODA Spaceback car) decodes RDS and hears weak signals at once. It is part of a well balanced system: receiver-feedline and rubber antenna on the metallic car roof. My pocket ultralight radios use the earphone cable as an aerial, so even being very good receivers, the antenna is far to be reliable with tricky and changing reception as it depends on the cable position at every moment. Uhmmm! I needed to find a better way to listen using my small toys.

In the shack I had some whips with male BNC and PL-359 connectors, but the Pocket ULR has a 3,5 mm female plug-in, so I found a “female BNC > male jack 3,5 mm” adapter and connected the whip. I chose a telescopic antenna 20/115 cm long folded/unfolded to test the Sangean DT-800T versus the SKODA autoradio, focused on the BOTB from 87,5 to 91,5 MHz. When a long whip is used some unwanted effects come into the scene. The first is related with audio; connecting the whip the sound must be heard via the small speaker so don’t forget to choose a quiet environment not to miss weak stations. The second one is pure physics; due to the whip length, the ULR 3,5 mm female plug-in gets extra strain and that could damage the inner weldings, so extra care must be kept in mind at any time.[]

Many thanks to SWLing Post contributor, Matt, who shares a link to a radio classifieds site he has created. Check it out!

The UsedRadioMall.com web site lists radios and items related to the subject of radio. The list may include receivers, transmitters, transceivers, amplifiers, antennas, parts, and components related to amateur radio, two-way radio, cb radio, broadcasting, recording, production, and hi-fi.

Introduction
Changes in ionospheric electron density caused by space weather and diurnal solar changes are known to cause Doppler shifts on HF ray paths. For example, see Figure 7 in Boitman et al., 1999. As part of the WWV centennial, 50 stations collected Doppler shift data for the original Festival of Frequency Measurement, demonstrating the value of volunteer participation in collecting this data. This June, we request that all amateur radio stations, shortwave listeners, and others capable of making high-quality HF frequency measurements help us collect frequency data for the June 10 annular eclipse. Researchers will use the crowdsourced data to investigate the superimposed effects of auroral particle precipitation and the eclipse on Doppler shift.

All you need to collect data is an HF rig connected to a computer running open-source software. A precision frequency standard, such as a GPS-disciplined oscillator, is desired but not required to participate. All ham operators and shortwave listeners around the globe are invited to join in, even if your station is far from the path of totality. Last year’s eclipse festivals included over 100 participants from 45 countries. The experiment will run from 7-12 June. All participants will receive QSL certificates and updates as the data is processed. This is a pilot experiment for HamSCI’s Personal Space Weather Station project, which seeks to develop a global network monitoring the geospace environment.

Passing by the Delano Transmitting Station

Many thanks to SWLing Post contributor, Tracy Wood, who snapped the photo above as he passed by this former IBB facility. Tracy noted:

The antenna field is still intact.
As a kid, the signals would leak into cheap AM radio sets in Oregon.

I could only imagine they would!  Thanks for sharing this, Tracy. Amazing to see that the antenna field is still standing.

RCI English section: goodbye (Radio Canada International)

Canada’s international broadcast service from the English language team of Radio Canada International has come to an end.

RCI, (originally the International Service, CBC-IS) was initially created towards the end of the Second World War. The purpose was to broadcast news and information from home via shortwave to Canadian military personnel fighting in Europe. It also began providing reliable news and information to recently liberated countries and to Germans still in the war.

That reliable news and information was considered of great value during the subsequent Cold War years, as several more languages were added to the service such as Russian, Ukrainian, Czech, Hungarian and Polish. Other languages sections included as Brazilian Portuguese and Japanese. With 14 language sections in 1990, and some 200 staff, the full English and French newsroom provided news of interest and importance for each language section specifically targeted to each of the various broadcast regions around the world.

Following a major budget cut of some 80 per cent in 2012, the shortwave and satellite service was terminated along with the majority of staff including the newsroom and some language sections. In recent years, only Chinese (Mandarin), Arabic, and Spanish remained along with English and French. RCI was transformed into a much smaller internet-based operation consisting of three people per language section.

In December 2020, the domestic public broadcaster CBC / Radio-Canada announced that the English and French sections of RCI would close for good in May. In their place curated stories from the domestic English and French public broadcaster will be provided.

A manager will now oversee the staff of eight who will adapt curated stories from the CBC and Radio-Canada into Mandarin, Arabic, and Spanish, along with Punjabi and Tagalog.

An effort was and is being made by the RCI Action Committee to preserve and even expand the service which has garnered great support from a former prime minister, former diplomats and many academics, but the end date has come. This is the last entry by the RCI English section.

From the English Section consisting of Lynn, Marc, and Levon, faithful and long-time popular replacement Terry Haig, and recently also Vincenzo Morello, and the many others over the all those years, we thank you for having shared our stories over these many years.[]


The Pirate Radio Capital: A sound tour with David Goren, radio producer and audio archivist (CRJ.org)

In 2018, David Goren, a radio producer and audio archivist, created the Brooklyn Pirate Radio Sound Map to collect the sounds of dozens of pirated broadcasts from across the borough. Pirate stations earn their name by hitching a ride on already licensed radio frequencies that typically cost commercial stations millions of dollars to acquire and set up. Nowhere in the country are there more pirate radio stations than in New York, where they provide a vital service to immigrant populations.

Goren estimates that New York has about a hundred pirate stations, transmitting from rooftops and attics to listeners seeking news from around the city and back home, as well as

entertainment and religious programming. The broadcasts bypass socioeconomic barriers and provide a means to seize control of the flow of information. But they are now at risk of extinction: Before Donald Trump left the White House, he signed the Pirate Act, which increased the authority of the Federal Communications Commission to fight pirate operations through mandatory sweeps in cities with high concentrations of pirate radio use. Pirate stations today face fines of up to two million dollars. “The people running these stations, they don’t have two million dollars,” Goren said. Broadcasters that don’t make it onto his sound map could be lost forever.

Shortwave effects pedal (Recovery Effects)

Inspired by espionage devices used during World War II and the Cold War, Shortwave transforms audio into clandestine operations of the past; Russian number stations, mysterious sounds transmitted by radio, and eerie sounds stored on early portable recorders.

Choose between 2 types of noise and interference, and control it with the Exposure parameter. Velocity and Focus control the amount of pitch stabilization. Shortwave will add an interesting emotional response and atmosphere to dry, simple sounds, or destroy a signal like no other fuzz pedal can.

In the emptiness of space, Voyager 1 detects plasma ‘hum’ (Cornell.edu)

Voyager 1 – one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space – still works and zooms toward infinity.

As the craft toils, it has long since zipped past the edge of the solar system through the heliopause – the solar system’s border with interstellar space – into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell-led research published May 10 in Nature Astronomy.

Examining data slowly sent back from more than 14 billion miles away, Stella Koch Ocker, a Cornell doctoral student in astronomy, has uncovered the emission. “It’s very faint and monotone, because it is in a narrow frequency bandwidth,” Ocker said. “We’re detecting the faint, persistent hum of interstellar gas.”

This work allows scientists to understand how the interstellar medium interacts with the solar wind, Ocker said, and how the protective bubble of the solar system’s heliosphere is shaped and modified by the interstellar environment.

Launched in September 1977, the Voyager 1 spacecraft flew by Jupiter in 1979 and then Saturn in late 1980. Travelling at about 38,000 mph, Voyager 1 crossed the heliopause in August 2012.

After entering interstellar space, the spacecraft’s Plasma Wave System detected perturbations in the gas. But, in between those eruptions – caused by our own roiling sun – researchers have uncovered a steady, persistent signature produced by the tenuous near-vacuum of space.

“The interstellar medium is like a quiet or gentle rain,” said senior author James Cordes, the George Feldstein Professor of Astronomy (A&S). “In the case of a solar outburst, it’s like detecting a lightning burst in a thunderstorm and then it’s back to a gentle rain.”

Ocker believes there is more low-level activity in the interstellar gas than scientists had previously thought, which allows researchers to track the spatial distribution of plasma – that is, when it’s not being perturbed by solar flares.[]

Guest Post: Methods for discovering and recording online radio programming for later listening

Many thanks to SWLing Post contributor, Bill (WD9EQD), who shares the following guest post:


Time Shifting Radio Programs for Later Listening

by Bill (WD9EQD)

There are quite a few programs on shortwave that I enjoy listening to for the actual program content.  If I am lucky, I will receive a strong enough signal to really enjoy the experience.  But all too often, I either can’t directly receive the program or conditions are such that listening is just not enjoyable.  What I was looking for was good quality sound that I could listen to on my schedule.

I could always just go to the station website and listen to the live stream of the program.  But what if there are two programs on different stations at the same time?  I would have to choose which one to listen to.  What I needed was a way to listen to the program on my schedule.

This write-up will be presenting several ways this can be accomplished.

Is the Program Streamed?

In many cases, it is possible to go to the program’s website and then listen to the latest program or even an archive of past programs at your convenience.  Some examples are:

Directly Record the Stream While It Is Being Broadcast

This method is a little more difficult and requires some setup. The method is to record the program directly from the internet stream of the station as it is broadcasting the program.  Once set up, the procedure is completely automatic and will continue to capture the program until it is disabled in the scheduler.

Let’s walk through a typical program that we want to record.  I like Alan Gray’s “Last Radio Playing” program on WWCR.  It is broadcast weekly on Wednesday at 6pm Central Time on 6115.  While I can receive the program over the air, it’s not very good reception, so I usually just stream it off the internet.

What I want to do is to set up an automatic computer program that will connect to the stream on Wednesday night, record the stream for one hour and then disconnect.  I use the program StreamRipper which can run on either Linux or Windows.

http://streamripper.sourceforge.net/

Since I have a spare Raspberry Pi 4 computer, I chose to use the Linux version.  The following description is based on Linux.  A similar method I’m sure could be done with the Windows version.

Fortunately, StreamRipper is in the current software repository for the Raspberry PI and I could just install it with having to do a compile.  I’m sure other Linux distributions probably also have it in their repository.  It was a simple matter to install it.  In Linux, Streamripper is run from the command line in a terminal window.

A typical command line for SteamRipper is:

streamripper station_URL_stream –a “filename” –A –d directory_path -l seconds

where

station_URL_stream is the http address of the audio stream.  Determining this can sometimes be challenging and some methods were recently discussed in a SWLing Post:

https://swling.com/blog/2021/04/robs-tips-for-uncovering-radio-station-stream-urls/

–a says to record the audio as a single file and not try to break it up into individual songs.

“filename” the filename of the resultant mp3 file goes here in quotes

-A again says to create a single file.

-d tells it the directory path to store the mp3 file.  Place the full directory path after the –d

-l specifies how long to record.  Enter the number of seconds after –l.

(note: this is lower case letter l)

For Last Radio Playing, the command line is:

streamripper http://67.225.254.16:3763 –a “Last Radio Playing” –A –d /home/pi/RIP/wwcr –l 3600

when executed, this would connect to the URL stream, record for 3600 seconds (60 minutes) and then disconnect from the stream  A file called “Last Radio Playing.mp3” would be in the wwcr1 directory.

Save this command line to a shell file, maybe wwcr.sh.  Then make this shell file executable.

Last is to enter a crontab entry to schedule the shell file wwcw.sh to be run every Wednesday at 6pm ct.

At the command line, enter crontab –e to edit the cron table.

Add the following line at the end:

0  19  *  *  3  /home/pi/wwcr.sh

then exit and save the crontab file.

This line says to execute wwcr.sh every Wednesday at 1900 (my computer  is on eastern time).

There are many ways to enhance the shell script.  For example, I have added the date to the mp3 file name.  My wwcr1.sh shell script is:

NOW=$(date +”%Y-%m%d”)

# WWCR1 Last Radio Playing

# Wednesday 7-8pm et

streamripper http://67.225.254.16:3763 -a “$NOW Last Radio Playing” -A -u FreeAmp/2.X -d /media/pi/RIP/wwcr1 -l 3600

This will create a MP3 file with the date in the file name.  For example

2021-0505 Last Radio Playing.mp3

Note: I named the file wwcr1.sh to denote that WWCR transmitter 1 was being streamed. Each of the WWCR transmitters have different stream URL.

Most radio streams work fine with  the default user agent but WWCR required a different user agent which is why the –u FreeAmp/2.X is added.  Normally, –u useragent is not required.  The default works fine.

For each program, just create a similar shell file and add it to the cron scheduler.

Streamripper is very powerful and has many options.  One option is for it to attempt to divide the stream up into individual files – one for each song.  Sometimes this works quite well – it all depends on the metadata that the station is sending over the stream.  I usually just go for a single file for the entire show.  Some stations are a little sloppy on whether the program starts on time – sometimes they start a minute early and sometimes run a minute over.  The solution is to increase the recording time to two minutes longer and then specify in the crontab file that the show starts a minute early.  It’s easy to adjust to whatever condition might be occurring.

Recording the BBC

I have found that the BBC makes it more difficult to use this procedure.   For one thing, they have just changed all their stream URL’s.  And they have decided NOT to make them public. When they did this some of the internet radios broke since they still had the old URL’s.  Of course it didn’t take long for someone to discover and post the new stream URL’s:

https://gist.github.com/bpsib/67089b959e4fa898af69fea59ad74bc3#file-bbc-radio-m3u

I have tested the Radio 4 Extra stream and it does seem to work.  For how long is anyone’s guess.

I found that while streamripper did seem to work on BBC, all the mp3 files came out garbled.  So the method above doesn’t seem to work with the BBC.

I went back to the drawing board (many hours on Google) and discovered another way to create a shell script that can be scheduled to record a stream.  This involves using the programs mplayer and timelimit.

First step is to install the programs mplayer and timelimit to the Linux system.  mplayer is a simple command line audio and video player.  timelimit is a program that will execute another program for a specific length of time.

First I created a shell script bbc30.sh:

#!/bin/bash

NOW=$(date +”%Y-%m%d-%H%M”)

# BBC Extra 4 – 30 minute program

timelimit -t1800 mplayer http://stream.live.vc.bbcmedia.co.uk/bbc_radio_four_extra -dumpstream -dumpfile /media/pi/RIP/$NOW-bbc.mp3

Note: The bold line above is all on one line in the shell file.

This script will execute the timelimit command.  The timelimit command will then execute the mplayer command for 1800 seconds (30 minutes).

The mplayer command then connects to the http stream; the stream instead of playing out loud is dumped to the dumpfile /media/pi/RIP/$NOW-bbc.mp3

The crontab entry becomes:

30  23  11  5  *  /home/pi/bbc30.sh

In this case, the program on May 11 at 2330 will be recorded.

Summary

In conclusion, Podcasts are the easiest way to get the programs.  But automatically recording directly from the station stream is really not that much harder to do.  Just be careful.  It’s very easy to accumulate much more audio than you can ever listen to in this lifetime.

One final note.  The use of a Raspberry Pi makes this a very easy and convenient method.  I run the pi totally headless.  No keyboard, mouse or monitor.  It just sits on a shelf out of the way and does it thing.  I either log in using VNC when I want the graphical desktop, Putty for the command line, or WinSCP for transferring files. The Pi stays out of the way and I don’t end up with another computer system cluttering up my desktop.

Besides recording several shortwave programs, I use Streamripper to record many FM programs from all around the United States.  It’s great for recording that program that is on in the early morning hours.

Internet radio with real buttons using Stream Deck (Bjørn Erling Fløtten)

How I used a Stream Deck Mini from Elgato in order to give my mother-in-law a super easy Internet radio experience.

By Bjørn Erling Fløtten, Trondheim, Norway. April 2021.

See also comments on Hacker News

Background

My mother-in-law is from Poland. When she stays in Norway in order to help us with babysitting she misses Polish radio. In principle this is easily accessible through the Internet now from all kind of devices.

BUT, my mother-in-law is not PC-literate, nor does she use a so called ‘smart’-phone. With my long experience in teaching people far younger than her simple mouse and keyboard techniques, I knew that operating Windows and finding Internet radio stations on her own would just be too cumbersome. I therefore had to create a super simple setup for her, and my hacker mind started to think.

(I did of course consider special purpose Internet radios. They should in theory be quite simple to operate, but they all have som kind of quirks that I did not like. And besides, constructing something of your own is of course always more satisfying.)

I want Real Buttons!

What I really wanted was big buttons with tactile feedback. I had earlier experienced with some Behringer products (sound mixing board) in order to demonstrate mathematical functions. The idea then was to use turning knobs and sliders in order to see how changing parameters changed the outcome of the function, especially graphs in 2D and 3D.

I thought this would be useful also for an Internet radio, but then I remembered having read about the Optimus Maximus keyboard (keyboard with programmable led icons on each key), and I thought such a product would be even better. This search led to Elgato and their Stream Deck Mini. This has 6 buttons, just enough for a radio. I might have preferred the bigger version with 15 buttons but their products are ridiculously expensive, so I had to be content with just 6 buttons.

In addition to the Stream Deck Mini my son donated his old school laptop with Windows 10 installed. It was a cheap ThinkPad L-series which, although 3 years old and somewhat battered from daily use to and from school, was quite capable of streaming some audio from the Internet. My son created a guest account in Windows 10 with auto login. He set ‘Fn lock’ as default, meaning that keys F1, F2 and F3 was volume off, down, up without having to press Fn. We also found a pair of speakers lying around in the house.

No programming necessary *

(* But understanding of HTML, URLs and Windows command line arguments is a requisite.)

Initially I thought I would make a Windows application for controlling which radio streams to play. But it turned out that Elgato’s accompanying software was quite capable by itself.

I assigned five of the six available buttons to launch the standard web browser (Google Chrome in this case) with a corresponding streaming URL (radio channel).

Annual Armed Forces Day Cross-Band Test set for May 7 – 8 (Southgate ARC)

The US Department of Defense will host this year’s Armed Forces Day (AFD) Cross-Band Test, Friday and Saturday, May 7 – 8, in recognition of Armed Forces Day on May 15. The event is open to all radio amateurs.

For more than 50 years, military and amateur stations have taken part in this exercise, designed to include amateur radio and government radio operators alike.

The AFD Cross-Band Test is a unique opportunity to test two-way communications between military and amateur radio stations, as authorized under FCC Part 97 rules. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly controlled exercise in which military stations will transmit on selected military frequencies and will announce the specific amateur radio frequencies being monitored.

The schedule of military/government stations taking part in the Armed Forces Day Cross-Band Test and information on the AFD message is available on the MARS website.

RAC Canadian Portable Operations Challenge Award (Southgate ARC)

The RAC Challenge Award: An Overview
Radio Amateurs of Canada is pleased to present a new Canadian Portable Operations Challenge Award for RAC members.

The objective of the new “RAC Challenge Award” is to recognize and encourage portable operations by RAC members from locations throughout Canada.

The new program will begin on Canada Day, July 1, 2021 and we hope it will become an annual event for RAC members.

Note: the following information is tentative as the new Awards program is still being organized so please stay tuned to this webpage for future updates.

Portable Operations
Portable operations are those in which Amateurs take their equipment, antennas and power supply to a location away from their home station to operate. This includes mobile stations, backpackers, DXpeditions and participation in events such as those described below:

Parks On The Air (POTA), a worldwide program of park activations – https://parksontheair.com/
Quebec Parks On The Air (QcPOTA) April 1 to December 31
Field Day: June 26-27
There are several other programs that celebrate portable operations including Summits on the Air (SOTA), Islands on the Air (IOTA) and the International Lighthouses and Lightships Weekend.

Features of the “RAC Challenge”
The new “RAC Challenge” will recognize all portable operations in which RAC members participate and will have similar features as a contest. Amateur Radio contests in VHF, UHF and the Microwave bands all have categories for “Rovers” – who move from grid square to grid square and “Backpackers” – who seek out hilltops from which to operate with highly portable equipment and antennas.

For many satellite operators, making contact with as many grid squares as possible is a mark of success. Some of those operators go on satellite DXpeditions to activate rare grids or operate from the intersections of grids to offer multiple grids with a single contact. In addition to being fun, these activities provide an opportunity for Amateurs to experience what is required to set up and operate under challenging conditions – valuable experience for emergency preparedness.

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 L, Pete Eaton, David Iurescia, and Troy Riedel for the following tips:


Podcast #294 – Reading the PIRATE Act / FCC & the Supremes Pt. 2

The PIRATE Act was signed into law more than a year ago, but the rules governing increased fines for unlicensed broadcasting are about to go into effect on April 26. The Act is intended to give the FCC additional tools for tamping down pirate radio activity in hot beds like Boston and Brooklyn, NY, but there are reasons to be skeptical.

Brooklyn-based writer, post-production mixer and field recordist David Goren joins to help us tease out the real-world implications. Goren is also the creator of the Brooklyn Pirate Radio Sound Map and has been monitoring and recording unlicensed radio activity in the borough for decades.

Also joining the show is Dr. Christopher Terry from the University of Minnesota. A professor of media law, he helps illuminate some of the legal and bureaucratic elements that complicate the Commission’s efforts. He also catches us up on the latest development in the battle over media ownership rules, with the Supreme Court issuing a narrow unanimous ruling in favor of the FCC’s most recent changes, but not quite addressing the decades-long gridlock in that policy area.

WSPR May Hold The Key To MH370 Final Position (Hackaday)

The disappearance of Malaysia Airlines flight MH370 after an unexplained course change sent it flying south over the Indian Ocean in March 2014 still holds the mystery of the wreck’s final location. There have been a variety of efforts to narrow down a possible search area over the years, and now we have news of a further angle from an unexpected source. It’s possible that the aircraft’s path could show up in radio scatter detectable as anomalously long-distance contacts using the amateur radio WSPR protocol.

WSPR is a low-power amateur radio mode designed to probe and record the radio propagation capabilities of the atmosphere. Transmit beacons and receiving stations run continuously, and all contacts however fleeting are recorded to an online database. This can be mined by researchers with an interest in the atmosphere, but in this case it might also provide clues to the missing airliner’s flightpath. By searching for anomalously long-distance WSPR contacts whose path crosses the expected position of MH370 it’s possible to spot moments when the aircraft formed a reflector for the radio waves.[…]

Bob Fass, Pioneer of Underground Radio, Dies at 87 (NY Times)

His provocative “Radio Unnameable,” long a staple of the New York station WBAI, offered a home on the FM dial to everyone from Abbie Hoffman to Tiny Tim.

Bob Fass, who for more than 50 years hosted an anarchic and influential radio show on New York’s countercultural FM station WBAI that mixed political conversation, avant-garde music, serendipitous encounters and outright agitation, died on Saturday in Monroe, N.C., where he lived in recent years. He was 87.

His wife, Lynnie Tofte, said he had been hospitalized with Covid 19 earlier in the month, but he died of congestive heart failure.

Vatican Radio celebrates 30th International Marconi Day

The Dicastery for Communication marks the 30th International Marconi Day with a celebration at Vatican Radio’s historic broadcast station outside Rome.

International Marconi Day is held every year on the Saturday closest to the birthday of the inventor of the radio, Guglielmo Marconi, on 25 April 1874.

This year’s commemoration fell a day earlier, and saw dozens of radio stations exchange messages, including Vatican Radio, which Marconi himself helped found in 1931.

The 30th iteration of Marconi Day was celebrated at Vatican Radio’s broadcast center at Santa Maria di Galeria, outside Rome.

Day for those who love radio

According to Dr. Paolo Ruffini, the Prefect of the Dicastery for Communication, it was “a day spent in a family spirit” for those who love the Radio and the man who invented it.

He noted that the broadcast station forms both the center and periphery of Vatican Radio, since it is the place where radio waves are emitted which carry the Gospel and the words of the Popes throughout the world.

Marconi’s favorite Radio

The 30th Marconi Day falls within the 90th anniversary year of the founding of Vatican Radio.

The great Italian inventor’s daughter, Princess Elettra Marconi, who was present for the celebration, recalled that the station was her father’s favorite, though he had founded several others.[]
