America’s Last Morse Code Station (The Atlantic)

Maritime Morse code was formally phased out in 1999, but in California, a group of enthusiasts who call themselves the “radio squirrels” keeps the tradition alive.

Calling all. This is our last cry before our eternal silence.” With that, in January 1997, the French coast guard transmitted its final message in Morse code. Ships in distress had radioed out dits and dahs from the era of the Titanic to the era of Titanic. In near-instant time, the beeps could be deciphered by Morse-code stations thousands of miles away. First used to send messages over land in 1844, Morse code outlived the telegraph age by becoming the lingua franca of the sea. But by the late 20th century, satellite radio was turning it into a dying language. In February 1999, it officially ceased being the standard for maritime communication.

Nestled within the Point Reyes National Seashore, north of San Francisco, KPH Maritime Radio is the last operational Morse-code radio station in North America. The station—which consists of two buildings some 25 miles apart—once watched over the waters of the Pacific and Indian Oceans. Both KPH sites shut down in 1997, but a few years later, a couple of radio enthusiasts brought them back to life. The crew has gotten slightly larger over the years. Its members call themselves the “radio squirrels.” Every Saturday, they beep out maritime news and weather reports, and receive any stray messages. Much of their communication is with the SS Jeremiah O’Brien, a World War II–era ship permanently parked at a San Francisco pier.

Audio Innovator Bob Heil Dies (Radio World)

Gave a unique sound to Frampton and was known in radio, audio and ham radio

Bob Heil has died, according to the company he founded. He was 83.

“Bob fought a valiant, year-long battle with cancer, and passed peacefully surrounded by his family,” Heil Sound posted on Facebook.

“Driven by a lifelong passion for sound, Bob’s pioneering work revolutionized how concertgoers experienced live sound.” [Here’ his official obituary.]

Heil was the inventor of the famous Heil Talk Box used memorably by musicians like Joe Walsh, Peter Frampton, Slash, Richie Sambora and others. He was invited to exhibit his innovations at the Rock and Roll Hall of Fame. He also was an active member of the amateur radio community.

In 2022 Bob and Sarah Heil transferred ownership of their company to President/CEO Ash Levitt and Director of Operations Steve Warford, Radio World reported at the time. “Sarah Heil has retired, but Bob will continue to do outreach work and product design within the amateur radio space under the title Founder and CEO Emeritus,” it stated then.

Decode the Enigma: Crypto Transmission from KPH on Saturday, July 23, 2022

The Maritime Radio Historical Society is hosting a brilliant on-the-air event via KPH. I’ve pasted full details below, copies directly from the Maritime Radio Historical Society announcement:


ATTENTION ALL AGENTS!

Crypto Transmission from KPH!

Background

The MHRS in cooperation with our good friends at the Cipher History Museum

will send a coded message in 5-letter groups via the facilities of coast stations KPH on Saturday July 23, 2022. The message will be encrypted using the famous Enigma code machine.

All KPH listeners are invited to try their hand at receiving and decrypting the message. Certificates will be awarded for proof of successful decode, first to decode and use of original hardware.

Mislaid your Enigma code machine? In the military you’d have some explaining to do, soldier. But for the KPH Crypto Event, no problem. See the ‘Enigma Simulator’ section below for a link to an easy-to-use Enigma simulator.

Enigma

The Enigma was the Germans’ most sophisticated coding machine for securely transmitting command and control messages via radio communications in WWII. It was considered so secure that it was used to encipher the most top-secret of messages.

The arrangement of Enigma’s rotors and plugboard connections provided a unique series of letter substitutions which changed with each keystroke. The daily rotor order and the ring and plugboard settings to be used were specified in a codebook distributed monthly to all users of a network.

For additional information on the Enigma please see Ralph Simpsons’ Cipher Museum History site

Crypto broadcast date, time and formats.

The crypto broadcast will commence at 2000Z (1300 Pacific) on 23 July on all KPH CW frequencies. The broadcast will consist of a ‘callup’ (in plain text) announcing the broadcast, followed by the cipher message. The callup and cipher messages will be sent at 15 WPM. The cipher message will be sent in 5 letter groups and the message will be sent twice to ensure proper reception.

The usual KPH channel marker or ‘wheel’ running at 20 WPM will precede the announcement for the crypto broadcast to give listeners a chance to tune to the strongest signal in their area.

The KPH CW frequencies are (in kc):

    • 426 (after an announcement on 500)
    • 4247.0
    • 6477.5
    • 8642.0
    • 12808.5
    • 17016.8
    • 22477.5

Upon completion of the CW transmissions, the broadcast will be repeated on all KPH RTTY frequencies. The RTTY transmission will be 170cps shift Baudot, 45 baud.

The KPH RTTY frequencies are (in kc):

    • 6324.5
    • 8427.0
    • 12585.5

Code Machine Key Settings – IMPORTANT!

Decoding an Enigma message requires the use of two keys: a Daily Key (valid for particular day), and a Message Key (unique to each individual message sent that day).

The Daily Key

Prior to decoding a message, the daily key must be set into your Enigma code machine. The daily key settings were specified in codebooks and distributed monthly. Please consult the following codebook to obtain the daily key setting for the GMT date of the broadcast.

Click HERE for the Enigma codebook. Use the “Armee-Stabs-Maschinenschlussel No 28” (Army Staff Machine Key Number 28). Notice each daily setting is across one line, starting with the first day of the month on the bottom of the sheet.

The Message Key

Starting in 1940, for additional security, the machine operator would randomly choose two groups of three letters to encode each message (in addition to the daily key settings above). These were known as the ‘message key’. The first group of three letters is used to encode the second group of three. Then the first group (in plaintext) and the second group (now encoded) are sent in the message header, along with the date and letter count, as explained in the above link. The recipient then uses the message key to decode the message. For more information see the following video on Enigma decoding procedures.

Click HERE to watch a video on Enigma coding procedures.

Enigma Simulators

So you had to toss your Enigma machine overboard when your U-boat was captured? Again, no worries. MHRS has you covered! Software simulations exist for the Enigma code machine.

Click HERE for an Enigma simulator. It is web-based, no download necessary.

Certificates

Upon proof of successful decode, the following certificates will be awarded:

– First to decode the Enigma message

– Successful decode using *original* hardware (i.e., an actual Enigma machine)

– All successful decodes of the message

To apply for a certificate, send the decoded message to [email protected] with the subject line ‘decoded Enigma message’. The First to Decode award will be based on the timestamp of the first email demonstrating a successful decode. For the Enigma Original Hardware certificate, send the decoded message *plus* a photo of your Enigma machine showing the daily key setting. Printed certificates will be mailed for ‘First-to-Decode and ‘Original Hardware’ awards. Certificates for ‘Successful Decode’ will be emailed in digital form suitable for printing at home.

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!

For Decades, This Radio Station Named the Dead. Few Still Listen. (NY Times)

[Note: this article may require login to read at the NY Times]

Afghans once tuned into Radio Afghanistan twice a day to hear the reading of death notices. But in an age of social media, the voice of the nation has lost much of its sway.

KABUL, Afghanistan — Through decades of coups, invasions and endless war, Afghans tuned their radios to Radio Afghanistan every morning at 7 and every afternoon at 4:05 to hear the names of the newly dead.

One of the voices they often heard reading those death notices belongs to Mohamad Agha Zaki, at the mic for the state broadcaster for more than 42 years now. For much of that stretch, his counterpart at the station has been Ziauddin Aziz, the clerk who rushes to Mr. Zaki with the messages the public brings to the station’s small “Death Advertisements” window.

“Ads today?” Mr. Zaki, half asleep, asked on a recent dawn after opening the door to Mr. Aziz’s knock. Outside, birds chirped and the new day’s soft light covered the peaks of the tall pine trees in the station’s compound in Kabul, the capital.

No, said Mr. Aziz, who had waited behind the door in the kind of deference saved for masters of a different era. They had gone weeks without anyone arriving at the little window — just four ads in 40 days, though certainly many more had died.[]

International Postal Service Disrupted (ARRL News)

The US Postal Service (USPS) has temporarily suspended international mail acceptance for items addressed to certain destinations due to service impacts related to the COVID-19 pandemic. This situation could result in the return or loss of mail, such as QSL cards, addressed to affected parts of the world. The USPS has posted a list of affected countries, which is updated regularly. The Postal Service will, upon request, refund postage and fees on mail bearing a customs stamp that’s returned due to the suspension of service, or the sender may re-mail returned items with existing postage once service has been restored. When re-mailing under this option, customers should cross out the markings “Mail Service Suspended — Return to Sender.”[]

Hamradio online

The Hamradio normally is the largest ham radio exhibition in Europe. But this year it cannot be held.

At the beginning of April, a team around the project manager Markus Heller, DL8RDS, started the project “Hamradio online”. This was only possible as DARC, the German hamradio society, started to introduce electronic collaboration tools long before Corona.

Within this virtual working environment a concept was developed of presentations, distinctions, and more. The program is being prerecorded and will partly be produced as live as possible. Especially the SDR Academy heavily depends on viewer feedback. There will also be videos from the Hamradio Convention that was held last March im Munich. These videos have not been published before.

The infrastructure is being maintained by the teams of the SDR Academy and “Facination Hamradio”. They produce the videos and streamline the installation so all action on the last weekend of June will happen smoothly. These transmissions will be transmitted through several Youtube cannels.

Obviously, personal meetings would be preferable. The advantage of this new solution are the possibly much more participants on both sides: audience and lecturers. The advantage is especially valid for the SDR Academy as most of it is done in English.

Nothing has been finalized. There is a preliminary program in German at https://www.darc.de/fileadmin/filemounts/gs/oeffentlichskeitsarbeit/Veranstaltungen/HAM_RADIO/HAMOnline_Sendeplan.pdf. Lectures held in English are announced in English. I hope an English version of the program will be created.

“Night of Nights” CW Event Returns Tonight!

Many thanks to SWLing Post contributor, Brian Smith (W9IND), who shares the following announcement:

“Night of Nights” CW Event Returns Friday (U.S. Time) 

“It was 20 years ago today,” say members of the Maritime Radio Historical Society, but they’re not covering a famous Beatles song.

They’ll certainly be on key, however, when they fire up two maritime CW stations, KPH and KFS, and their amateur radio club station, K6KPH, for the 20th annual “Night of Nights” at 8:01 p.m. Eastern Time on Friday, July 12/0001 UTC Saturday, July 13. (Alas, several previously participating stations will be absent again this year, including ship-to-shore stalwart WLO of Mobile, Alabama, and a quartet of Coast Guard stations.)

This weekend’s event marks the date in 1999 when commercial Morse code operations ceased in the United States. One year later, the preservation-minded MRHS staged its first “Night of Nights,” treating shortwave radio enthusiasts to the dits and dahs of historic maritime station KPH and other callsigns that were once presumed dead on shortwave CW frequencies.

This year, the society has put out a special appeal to anyone (licensed or not) with CW proficiency to help operate K6KPH. While KPH and KFS transmit “code wheels” (repeating messages), personal messages, and tributes to long-gone maritime stations and operators, K6KPH will make CW contacts with other amateur stations on 3550, 7050, 14050 and 21050 kHz.

Whether reporting for CW duty or not, the public is welcome to observe today’s event and tour the facility, located at 17400 Sir Francis Drake Boulevard in the Point Reyes National Seashore. Doors open at 3 p.m. local (Pacific) time.

And if you’re not within driving distance, you can tune in the Morse signals on the following medium wave and shortwave frequencies:

KPH:  426, 500, 4742.0, 6477.5, 8642.0, 12808.5, 17016.8, 22477.5 kHz

KFS:  12695.5 kHz

Reception reports go to P.O. Box 392, Point Reyes Station, CA 94956. Please include an SASE if you’d like a QSL.

One of the most stunning sights of the Bay Area is the historic KPH Radio Station, also known as Marine Coast Station KPH. To reach the station, you must first pass through a clerestory tunnel of cypress trees near the Point Reyes National Seashore.[…]

KPH began providing Morse Code telegram service to ships at sea in the early 20th century, broadcasting from the Palace Hotel in San Francisco (where the station gets its PH call sign). The 1906 earthquake forced the station to move until it was eventually acquired by the Radio Corporation of America (RCA) and found its home in Marin County. The Receiving Station is a classic white Art Deco structure built in 1920. The transmitters themselves, in nearby Bolinas, are a similar style.

At the time, there were dozens of stations like KPH around the United States, though KPH was one of the biggest, sometimes referred to as “the wireless giant of the Pacific.” When the station fell into disuse, land contractors were set to demolish it, including its antennas, to build condominiums. But Globe Wireless acquired the site in 1997 and it was left untouched.[…]
