Atlas Obscura: Time to update the Spelling Alphabet?

Photo by Annie Spratt

Many thanks to SWLing Post contributors, Paul Evans and Eric McFadden, who share this article from Atlas Obscura where author Dan Nosowitz asks if it’s time to update the spelling (a.k.a. phonetic) alphabet:

WHEN SOMEONE ON THE PHONE—THE doctor’s office, the bank, the credit card company—asks for my name, I always offer to spell it out—it’s a pretty uncommon surname. So far as I know, there are somewhere between 10 and 20 Nosowitzes in the world, and they’re all closely related to me. Because it’s uncommon, and because it would be a problem if my bank writes my name down as “Moskowitz,” I err on the side of caution. “N as in Nancy, O, S as in Samuel, O, W, I, T as in Thomas, Z as in Zebra,” I chant.

This uses what is what’s called a “spelling alphabet,” or, confusingly, a “phonetic alphabet.” (The latter is confusing because it has little to do with phonemes, or a unit of sound in a language. Plus there’s the International Phonetic Alphabet, which is something else entirely.) The history of spelling alphabets is fascinating and winding, but it’s notable that there hasn’t been an official update to the most commonly used English version in about half a century. We might be in need of one. As mobile phones have replaced landlines, call quality has, strangely, gone down. The general connectivity of the world—including the ease of international video calls and the use of foreign call centers—means that spelling out a name or word is an increasingly common practice. A modern, updated, globally friendly English spelling alphabet would be pretty useful right now, but getting people to use one might be harder than you’d think.

[…]For about 80 years, governments and corporations futzed with these spelling alphabets, and learned that some stuff didn’t work—it turns out, for example, that “Lima” is also the Malay word for the number five. A tremendous amount of research, time, and money was invested into figuring out the optimal spelling alphabet—at least for the three languages that the International Civil Aviation Organization (ICAO, the United Nations agency that handles air transportation) felt significant enough to have one (English, French, and Spanish). The ICAO scrambled, using researchers across the globe on the problem, and by 1959 had finalized what is today probably the best-known spelling alphabet: Alfa, Bravo, Charlie, Delta, Echo, and so on. (As a side note: “Alfa” is not a typo. The whole “ph equals f” thing is confusing, and reasonably so, for non-English speakers. The same goes for the alphabet’s J—Juliett with a doubled final letter so the French won’t say “Juliay.”)

That is the now the standard alphabet for organizations including NATO (which often lends its name to the alphabet), the Federal Aviation Administration of the United States, the International Amateur Radio Union, and pretty much any international group that wants or needs a standard. It’s certainly the most commonly used spelling alphabet in the world, but it is, as most of these alphabets are, exceedingly Anglocentric.[…]

Funny story: Last week, I visited my parents and started cooking a nice dinner. Ten minutes into baking a roasted vegetable dish, the oven’s temperature started rising unexpectedly because the oven’s control board (turns out) could no longer receive the temperature probe data. Its fail safe was to shut down the oven completely.

After a little online research, I found the parts that had most likely failed, so I pulled the oven away from the wall, disassembled the back panel, evaluated the parts, gathered the model number, and called a local appliance parts store.

When the associate answered the phone I described the problem and the parts I might need. He agreed with my diagnosis, so asked for the oven’s 16 character model number :

Me: LWZTF700…

Him: LWCDF700…???

Me: Sorry, let me try again. Lima Whiskey Zulu Tango Foxtrot…

Him: Excellent! I copy that. Say, were you in the military?

Me: Ha ha… No, I’m a ham radio operator.

Him: I am too! My call sign is….

He then proceeded to give me their best price on the parts.

I’m sure he hears variations of the spelling/phonetic alphabet multiple times a day and appreciates it when his customers use the one most widely accepted!

For your reference, here’s the standard spelling alphabet currently accepted by NATO, the FAA, and the IARU:

Vatican Radio’s Brazilian Portuguese language programming returns

2 Replies

Many thanks to SWLing Post contributor, David Iurescia (LW4DAF), who shares the following news via Zenit.org:

“The Brazilian program of Vatican Radio-Vatican News resumes its short-wave transmissions in the Amazon region,” announced the portal of Vatican News in Brazilian today, Monday, July 15, 2019, given the proximity of the holding of the Synod for Amazonia (October 6-27, on the theme: “New Ways for the Church and For An Integral Ecology.”

“For over 61 years, Brazil has been listening to the Pope’s voice through Vatican Radio. On August 1, after a period of absence, the Brazilian program of the papal station will return to Amazonia in short wave,” announced the same source.

And it adds: “Thus Vatican Radio-Vatican News shows its attention to an important region of Brazil, for which the radio is its main means of communication. The Pope’s voice will be listened to again on radio by more than 25 million people, who live in this lung of the planet. The decision to broadcast in short wave responds to the geographic reality of Amazonia.”

Vatican News recalls: “Created in March of 1958, twenty-seven years after the foundation of Vatican Radio, on February 12, 1931, the Brazilian program has followed seven pontificates, from Pius XII to Francis. At present, the Brazilians of Vatican Radio-Vatican News offer a wide gamut of daily programs in a multi-media style through different platforms: radio, Web and social networks.”

It also recalled: “On the occasion of the 50th anniversary, in March 2008, Benedict XVI expressed his gratitude to the said program for the inestimable service of proclaiming the Gospel and promoting communion between the Church and the people of Brazil.”

LZ1AQ Evaluates Impact of the Height Above the Ground on Mag Loop Performance

Many thanks to SWLing Post contributor, Harald Kuhl (DL1AX), who shares the following article on LZ1AQ’s website:

Published on: 2018/11/20, Rev. 1.0 July 2018, Rev. 1.1 Nov 2018

Author: Chavdar Levkov LZ1AQ

Setup

Two identical small loops were placed one above the other according to Fig.1. One of the loops is very low – almost on the ground. The other one is placed at height which usually is used by the loop users. Two AAA-1C wideband active antenna amplifiers were used. Their gain difference was not more than 0.3 dB. The feeder was FTP cable each 20 m long. No cable baluns were used. The outputs were connected through two way antenna switch to a SD RX (Perseus). I used a measurement technique described in – A Periodic Switching Technique to Compare Receiving Antenna Performance in the Presence of Strong Fading. This is a precise method to compare two receiving antennas with real sky wave signals and the resolution can be less than a decibel. The idea is to switch periodically between two antennas and to estimate their difference on a calibrated graphic strength meter of a SD radio.[…]

I’ve often assumed height had little effect on the performance of an HF loop antenna–this evaluation seems to support that theory. Thanks for sharing this, Harald!

Bill’s NJARC swap meet deal and some tailgate photos

2 Replies

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

This morning (Saturday July 20), I went to the New Jersey Antique Radio Club (NJARC) Summer Swap Meet.

They typically hold three Swap Meets each year at various locations This time it was at the InfoAge Science

History Learning Center in Wall, NJ. The InfoAge Center has many exhibits including:

InfoAge Space Exploration Center

World War II Radar

Marconi Wireless Room

Radio and Television Museum

Vintage Computers

plus much more

Check out this link.

If you are ever in the area, I highly recommend a visit to it.

The Swap Meet was held outdoors and it was a hot humid morning – 80 degrees at 6 am with 90 percent humidity. By 9 am it was 90 degrees. But it was worth the hour trip.

I acquired one new radio – the Nova-Tech Pilot II Direction Finding 4 Band transistor radio. It’s in great condition and is working. It’s an interesting radio.

The four bands are Beacon (190-400 kHz), Broadcast (550-1600 kHz), Marine (1.6-4.5 MHz) and VHF (108-136 MHz).

There is a rotatable antenna on the top that is used to get your bearing. The top of the radio has the Bearing in degrees. It includes Squelch and DF Level controls; both can be switched off. The DF Level is the RF Gain and I read somewhere that when it is activated the AGC is switched off.

I was very fortunate in that the radio came with the three telescoping antennas – all in perfect condition. It also included the original AC Power Adapter.

All for only $25. A great bargain.

The radio seems very sensitive on the Broadcast Band.

I tuned it to my standard test weak station – WALK, 1370, in Patchogue, NY. This station is a 500 watt repeater station to WHLI, 1100 in Hamstead, NY. With most of my radios, I can barely hear a station in the noise. The exception is the Panasonic RF-2200 which can pick it up the best. The Pilot II could pick up a readable signal of WALK.

Very impressive.

Below are some photos of the radio.

Bill also included the following photos from the New Jersey Antique Radio Club (NJARC) swap meet:

Thanks for sharing this, Bill! No doubt, you snagged a fantastic deal on the Nova Tech Pilot II. My dear friend Michael Pool (who passed away earlier this year) acquired one and loved it. Here’s a link to his guest post about this cool DF receiver.

Thanks for sharing the photos and links to the NJARC swap meet. Looks like an event I’d certainly love to attend!

David Warren: Radio enthusiast who invented the “Black Box” flight recorder

1 Reply

As a schoolboy, David was fascinated by electronics and learned to build his own radio sets (Source: BBC and the Warren Family Collection)

Many thanks to SWLing Post contributor, Paul W4/VP9KFPaul W4/VP9KF, who notes that David Warren, inventor of ‘Black Box’ recorders was a ham radio operator and radio enthusiast.

The following short biography comes from this memorial website:

David Warren (full name David Ronald de Mey Warren) was an Australian inventor. He is most famous for his invention of the Flight data recorder (invented in 1956), or more commonly known as the “black box”

The “Black Box” is a device that records in-flight conversations and data. Warren came up with the idea of recording the flight crew’s conversation on a device that could be protected to increase its chances of surviving the crash. Although it has the name “Black Box”, it is coated with heat-resistant bright orange paint for high visibility in a wreckage, and the Black Box is usually mounted in the aircraft’s tail section, where it is more likely to survive a severe crash.

David Warren was born on the 20th of March, 1925, on Groote Eylandt, an island off the coast of the Northern Territory. He was the first child of European descent born on the island. When he was at the age of four, he was sent to Tasmania and Sydney to spend most of the next 12 years in boarding schools (Launceston Grammar School in Tasmania and Trinity Grammar School in Sydney).

Australia’s first major air crash in 1934 claimed the life of David’s father.

Warren had received a crystal set from his father just before the disaster that started his interest in amateur radio and electronics. Almost 20 years later, when the age of commercial jet aircraft was just beginning, Warren worked as a chemist, specialising in aircraft fuels at the Aeronautical Research Laboratories.

Dr Warren was working as a scientist at Melbourne’s Aeronautical Research Laboratory, where he was helping to investigate the 1953 mystery crash of a Comet jetliner. New fuels being used in Jets in the early 50’s were more likely to become explosive at altitude than conventional aircraft fuels and this was identified as a possible cause of the Comet crash. While listening to the arguments over possible causes of the Crash, Warren realised that the solution could be at hand if someone on the plane had been carrying a device similar to the then newly released “Protona Minifon” portable recorder that he saw at a trade fair.

The device would be fire proof (using steel wire as the recording medium like the “Pocket Recorder”) and erase itself so that the last hours of the flight were always recorded. The device consisted of a single steel wire as the recording medium and provided four hours of recording and automatically switched itself on and off with the aircraft. It was during this period that Dr Warren incorporated the idea of recording instruments on a separate channel – his interest in electronics as a schoolboy was brilliantly applied to turn instrument readings into recordable dots and bleeps.

The recorder was well received in England (where the name “Black Box” was made up by a journalist at a briefing) and also in Canada where the idea was seen as a potential addition to beacons being developed there.

Warren continued to lead the project, developing the Flight Memory device to record more instruments with greater accuracy. This led to the first commercially produced flight recorder-the Red Egg.

A further disaster at Wintoon in 1967 saw Australia become the first country to make both flight data and cockpit voice mandatory on all jets.

While a student at the University of Sydney, David met Ruth Meadows, who became his wife and lifetime supporter. Together, they raised a family and shared an interest in science and education. When he retired, David and Ruth lived in Caulfield South, Victoria, in regular contact with their four children and seven grandchildren.

David died at the age of 85 in 2010, 19 July, Melbourne, Australia. After his death, He was buried in a casket bearing the label “Flight Recorder Inventor; Do Not Open”.

Then in June 2012, the ACT Government named a road, David Warren Road, in the suburb of Hume in recognition of Warren. On 25 March 2014, the Defence Science and Technology Organisation renamed their Canberra headquarters to the David Warren Building.

Thanks for sharing this, Paul! Fascinating…

Note that the BBC recently published an amazing piece about Dr. Warren on the 9th anniversary of his passing–click here to read.

There are a hundreds of fascinating off-air radio recordings in our Shortwave Radio Audio Archive.

One of our frequent contributors, Tom Laskowski, has digitally converted numerous magnetic tape recordings from his personal collection to share with the archive. Tom made the following recording of the Voice of America on July 20, 1979 at 0500 UTC on the 31 meter band.

Tom notes:

The first 4:30 is from a VOA newscast that aired before the main part of the program.

The main recording was presented on the 10th anniversary of the Apollo 11 moon landing. I enjoy listening to this every year on the landing anniversary.

I’ve enjoyed listening to this 10th anniversary presentation as we, today, celebrate the 50th anniversary of the moon landing::

[Update:] Tom also shares another recording that marks this anniversary:

I thought this might be [another] appropriate file to upload considering we are marking the 50th anniversary of Apollo 11. I recorded this program thirty years ago on July 20, 1989 [5.975 MHz at 0400 UTC] the 20th anniversary of the Apollo 11 moon landing. Omnibus takes a look back at the historic Apollo mission and how and why it happened:
