From the Isle of Music, April 15-21:
April is Jazz Appreciation Month around the world, and we are going to celebrate by taking a look at some of the roots of modern Cuban Jazz in both Cuba and the United States. This week, we are going to listen to some important and historic recordings made in the United States as what we now call Afro Cuban Jazz was being born.
Four opportunities to listen on shortwave:
1. For Eastern Europe but audible well beyond the target area in most of the Eastern Hemisphere (including parts of East Asia and Oceania) with 100Kw, Sunday 1500-1600 UTC on SpaceLine, 9400 KHz, from Kostinbrod, Bulgaria (1800-1900 MSK)
2. For the Americas and parts of Europe, Tuesday 0000-0100 UTC on WBCQ, 7490 KHz from Monticello, ME, USA (Monday 8-9PM EST in the US). This has been audible in parts of NW, Central and Southern Europe with an excellent skip to Italy recently.
3 & 4. For Europe and sometimes beyond, Tuesday 1900-2000 UTC and Saturday 1200-1300 UTC on Channel 292, 6070 KHz from Rohrbach, Germany.

Many thanks to SWLing Post contributor, Moshe Ze’ev Zaharia, who submits the following videos of his reception of Radio Kuwait at 10:30 UTC on April 6, 2018 from his home in Israel.

Moshe notes that the signal was of blowtorch strength and, for at least 45 minutes, there was an ever-present delay/echo. Moshe’s receiver is a (beautiful!) Zenith Trans-Oceanic T600 and his antenna a 15 meter wire:

Many thanks for sharing, Moshe!

Did anyone else note this echo? I wonder what happened at the Radio Kuwait transmitting station to make this happen?  Or, perhaps, it was a fault with the audio feed they received? Please comment!

St. Bandon (3B7A): An all-SDR DXpedition

Many thanks to SWLing Post contributor, Mike Hansgen (K8RAT), for passing along this press release from SunSDR:

The 3B7A Saint Brandon team is now active from Saint Brandon and we are exited! This is the first major DXpedition that will be using only SDR transcievers in its setup.[…]

SunSDR2 Pro

Using past experience from their successful FT4TA expedition to Tromelin island and FT4JA Juan de Nova island Expedition, the experienced team lead by F5UFX Seb build their St Brandon setup around the SunSDR2 PRO transceiver, the SPE 1.3K-FA amplifier and ModMic attachable boom microphone.

3B7A will have 5 x HF stations on air simultaneously. Each station will have a SunSDR2 PRO with E-Coder hardware controller, an amplifier, and a ModMic. Logging is done using WinTest in network configuration and all stations will be able to operate CW, SSB or RTTY.

All 5 stations will have will have identical configuration from the keyboard to the amplifier. This will keep the operator focused on the pile-up and improve redundancy in case of any equipment failure.[…]

Note that I believe the January 2018 Bouvet Island (3YØZ) DXpedition would have also been one of the first major ham radio DXpeditions to use SDRs (FlexRadio SDRs). Sadly, due to weather and engine problems, 3Y0Z were not able to activate.

Clyde Haehnle: Loss of a broadcasting icon

Museum Icon Passes Away

The National Voice of America Museum of Broadcasting mourns the loss of one of its major leaders and benefactors. Clyde Haehnle passed away peacefully on Sunday, April 8th.   Over the years, this icon in the development of broadcasting technology, not only locally but nationally, was the driving force behind the museum.

A veteran broadcasting engineer and executive, Mr. Haehnle was instrumental in the early meteoric development of Powel Crosley’s WLW. While working at WLW, fresh out of electrical engineering school at the University of Cincinnati, he was assigned in 1942 to work on design and construction of VOA-Bethany Station, the transmission facility of the newly- minted Voice of America. The facility operated from 1944 thru 1994 and beamed programs worldwide from the highest power shortwave transmitters built in the world at that time.

The rhombic antenna design requiring extensive mathematical calculations fell to Mr. Haehnle. His work accomplished with pencil, paper and a slide rule resulted in some of the most efficient antenna arrays ever built and enabled the VOA programs transmitted from the hilltop north of Cincinnati to be heard by eager listeners worldwide. P of Engineering at AVCO Broadcasting. He held many patents in electronic technology and continued to be a curious and thoughtful proponent of technology well into his ninth decade.

Mr. Haehnle’s untiring leadership and support has enabled the National Voice of America Museum of Broadcasting to develop into a rich educational institution celebrating the role broadcasting has made in the dissemination of programs globally encouraging democratic principles to truth-starved audiences.

The Museum plans a celebration of Mr. Haehnle’s extraordinary life later this spring.

Many thanks to SWLing Post contributor, Dave Richards (AA7EE),  who writes:

Thomas – I know you’ve posted before about the NBC chimes, so I thought you might be interested to know that CHRS, the California Historical Radio Society, has acquired one of 8 original NBC chime machines. They don’t think that more than a dozen were ever made. CHRS have their own building on the island of Alameda, CA, and are putting a huge amount of time and work into amassing an impressive collection of vintage radio gear. [I]f you scroll about 1/3 way down this page, you’ll see the news, along with a brief history of an NBC chime machine, and pictures of the one they now have in their collection. It is a rare find indeed!

Very cool! Thank you for sharing this, Dave! I’m very happy to hear that these chimes have proper custodians.

“Threatened radio shut down” in Germany

Germany – up to 10 million people could be hit by threatened radio shut down

The airwaves across many parts of Germany could fall silent next week due to a financial dispute between radio stations and an FM broadcasting provider.

The company Media Broadcast announced on Friday that it would cut off FM broadcasters for several radio stations if they did not immediately fulfil certain payment demands.

“Up to 10 million radio listeners could be affected by their FM broadcaster being cut off from Wednesday onwards,” company head Wolfgang Breuer told Die Welt.

Major public service broadcasters such as MDR, NDR and Deutschlandfunk are among those who could be cut off, the newspaper reported.

The dispute began when Media Broadcast, formerly a subsidiary of Deutsche Telekom, decided to move focus away from FM radio and onto digital platforms last year. The shift meant that broadcasting antennae across Germany, for which Media Broadcast had previously been responsible, were sold to private investors.

Broadcasters and their network operators were then left furious when many of the new owners raised prices for the use of their antennae, leading to a stalemate in business negotiations.

Hessian broadcaster FFH told dpa that a 50 percent rise in the cost of antennae use had left them with a “massive problem”.

In order to break the stalemate, Media Broadcast recently agreed to continue operating all antennae until the end of June, so as to provide more time for negotiations. Yet such an arrangement would still require the stations to contract the company during that period.

Media Broadcast now claims that around 75 percent of stations have not done this, and has threatened to cut these stations off if they do not officially contract the company by Monday.

Though digital and online streaming radio will still be available, the mass cut-off of FM radio broadcasts would affect a huge proportion of the population. According to Bild, around 92.7 percent of Germans said they still preferred listening to radio on an analogue device in a poll last year.

Shortwave Radio Recordings: Ham radio contacts between W2PVF (SK) and two Antarctic Stations, circa 1974

Many thanks to Bill Hemphill (WD9EQD) who is one of our newest contributors at the Shortwave Radio Audio Archive (SRAA). Bill approached me at the Winter SWL Fest this year noting that he has a wide variety of radio-related audio recordings to share with the SRAA and the SWLing Post.

This week, Bill shared two fascinating tape recordings he originally acquired from an estate sale box.  These recordings were originally made in 1974 by the late Jim Hayward (W2PVF) in Absecon, New Jersey (USA) with two different ham radio stations in Antarctica.

This first recording is between W2PVF and KC4AAC of Palmer Station. The audio starts mid conversation:

The second recording is between W2PVF and LU1ZE of the Argentine Antarctica Station. The operator at the microphone is W1PV. The recording even includes a phone patch:

Bill, thanks so much for sharing these recordings–I thoroughly enjoyed them!

I’m so impressed with the audio and signal quality of the Antarctic stations.  In 1974, we were approaching a solar minimum in Solar Cycle 20. Still, I bet conditions were better than anything we’ve seen in over a decade!

I’m curious if any Post readers have ever made contact with either of these stations or even know the operators in the recordings? Bill notes that  Jim (W2PVF) was president of the local Atlantic City Electric Company for many years. Would be fun to share these recordings with the some of the original operators, if they’re around!
