Photo Tour: The Edward R. Murrow Transmitting Station

Yesterday, I posted a photo and asked if you guess where I was when I took the shot.

Those of you who guessed the Edward R. Murrow Transmitting Station (formerly, “VOA Site B”) near Greenville, North Carolina, were absolutely correct!

My buddy, John Figliozzi, gave a presentation about NASWA and the Winter SWL Fest at the NASB (National Association of Shortwave Broadcasters) which was held in the Raleigh area, May 9th and 10th. Due to a conflict, I was not able to attend the NASB meeting this year, but I did arrive at the conference hotel late Thursday where I met a handful of attendees. I had previously invited John to join me on the station tour, and he was quite happy to do so!

Macon Dail (WB4PMQ), the transmitting station’s Gold Medal award-winning Chief Engineer, made time to give us a tour Friday, May 10, 2019.

And now, on to the photo tour of this remarkable facility.  My inclination is to caption each photo…but I know if I attempt this, I won’t post this gallery for several months!  Instead, I’ll roughly divide the photos by the various sections of the site. Note, however, that there are more than one hundred photos in this detailed post––to decrease its length, some of the photos have been placed in clickable thumbnail galleries. Those of you who receive the SWLing Post as an email digest, I would strongly encourage you to view this post directly on our website, so all of the gallery images will appear.

Enjoy!

Station entrance, lobby, and library

The Front Lobby

In this photo, Macon is showing John one of the notebooks, which is chock-full of reception reports from listeners. This notebook, as you can see, is prominently displayed in the front lobby.

We found our friend Rich D’Angelo in the stack of reception reports.

In a mezzanine above the control room, there is a space that houses a library, a presentation/classroom area, and even a small workout/fitness room.

View into the control room from the mezzanine.

Installing new transmitters

Macon and his team are in the process of installing modern transmitters sent from other IBB sites. As you might imagine, this is a tedious process, and requires highly-skilled technicians.

Antenna switching bay and feed lines

In this photo, we’re looking straight down a 50 kW feed line in conduit which leads to the switching bay. Normally, this would not be accessible, but this line is being built for a new transmitter.

The antenna switching bay is truly massive…

Wow, what a tour…

John and I enjoyed our in-depth tour of the Edward R. Murrow Transmitting Station! The staff, as always, were incredibly welcoming and accommodating.

I believe this was my fourth tour; nonetheless, I still discovered new things, and it’s no wonder. The staff of the station are constantly upgrading, updating, and tweaking the performance of their equipment. This is the reason their signals are always full-fidelity and crystal-clear on the air.

I’m simply amazed by all they accomplish.  Keeping this station running is certainly a labor of love.

Of course, this won’t be my last visit to the station.  I fully intend to return, if not later this year, at least next, to check out the new transmitters in operation.  Stay tuned! To this active VOA station.

Many thanks to SWLing Post contributor, Alan Roe, who writes:

There is an interesting article/podcast by R France Int
entitled “The power of radio during British-mandated Palestine”.

“On 30 March 1936, the British High Commissioner of Palestine, Arthur
Wauchope, inaugurated the Palestinian Broadcasting Service, the PBS. It
was the second broadcaster to be established in the Middle East, after
Radio Cairo in 1934, and featured programmes in Arabic, Hebrew and English.

It covered the region of Palestine, Jordan, Syria and Lebanon, as well
as parts of Egypt. The new transmitter was in Ramallah and the
broadcasting offices were in Jerusalem.”

Ultra-Rare Tristan da Cunha QSL: The Art of the Hunter-Killer QSL Pursuit

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following guest post:


Ultra-Rare Tristan da Cunha QSL: The Art of the Hunter-Killer QSL Pursuit

by Dan Robinson

Those in the QSL collecting community are likely to have noticed the recent appearance on Ebay of one of the rarest QSL cards in existence.

The QSL from Tristan da Cunha showed up around March 19th with a six day auction window, by a seller in France who also listed a number of other older QSLs.

For a description, the seller wrote: “QSL card from radio station ZOE the broadcasting service of Tristan da Cunha 1973. A very rare and sought after QSL. Seldom seen on Ebay. . .”

Understatement to be sure. Along with QSL letters directly from Biafra, the breakaway state in Nigeria many decades ago, QSLs from Tristan da Cunha are pretty much NEVER seen.

ZOE Tristan was a station intensively sought by thousands of DX’ers when it occupied the 90 meter frequency of 3,290 kHz with a power of only 40 watts.

Only a handful of DX’ers ever heard and QSL’ed Tristan.  In this story still accessible online–three persons from South Africa are described as having received QSLs, along with two others, in the UK and in Florida, USA.

As a young DX’er, I remember reading the entry in the WRTH and the feeling of frustration with the reality that it was impossible to hear with my receivers, largely due to its limited broadcast time and hour of transmission which I recall was 2000 UTC.

eBay bid history

As the hours ticked away in the auction, the number of bids increased. The ending time fell in overnight hours EDT. This increased chances of obtaining the card for a lower price, though bidders in other parts of the world would surely be stationed at their PCs and on their phones in the final hours of the auction.

I have been one of the most active QSL hunters in the world, and there are specific strategies involved in competing for QSLs.

For purposes of this article, I’ll just note that these involve constant attention, especially toward the end. As an auction nears conclusion, it’s important to “test” the bid level to assess the likelihood of the item selling at that or a much higher price.

Some cards or verification letters have the potential to bring hundreds of dollars. I assessed that this Tristan card could bring as much as $500-$1,000 depending on whether someone had “gone high” with an automatic “knock out” bid using either the Ebay system or other auto-bidding site.

As you can see in the image, from a starting price of $4.00 on March 19th the Tristan card had reached only $50.00 several days later on March 23rd.  The $100 mark was reached on March 26th.  One bidder retracted his $150 bid at one point.

On the final day March 26th, it was anyone’s guess how high the Tristan card could go.  The card only inched up in small bid increments, surprising given its rarity.

If one assumed that any of the four bidders involved placed a “knock-out” auto-bid, and if two had placed such a bid, in the final seconds the Tristan QSL could quickly shoot up from the $142.50 level to whatever the extremely high maximums would be.

Due to the rarity of the card, my bid fell in the “knock out” category.  I went to sleep reasonably confident, but concerned the competition could drive the price of the card through the roof.

When I awoke the next day, I was relieved — the Tristan card, complete with its original postage stamp, rubber stamp mark, and signature by the station, was mine.  The price:  an astoundingly low $145.

Such is the excitement involved in being a “hunter-killer” QSL card collector. As I noted in SWLing Post last year, I now own three of the world’s rarest QSLs.

These include possibly the last remaining QSL letters sent directly from Radio Biafra, a QSL from Portuguese Macao, and now this wonderful ZOE Tristan da Cunha card.

That is–actually two ZOE QSLs.  About a decade ago, while scanning Ebay listings for QSLs, I was astounded to see a ZOE card listed as part of a group of amateur radio QSLs being offered by a seller in Europe.

I couldn’t believe what I was seeing. Until that point I had seen not a single ZOE QSL appear since the Ebay market for QSLs began to heat up in the late 1990s

(Source: SWL Card Museum)

This particular card, which you can see posted at the excellent “SWL Card Museum” site has “ZOE” printed in large letters, like the card that I recently won, a date of reception as “June 1, 1977” but no signature.

The card did arrive with the original envelope in which it was sent to a European DX’er, complete with a postage stamp and postal mark for Tristan.

Why that particular ZOE card was not signed by someone at the station, and why it was placed in an envelope rather than post marked on the card itself, remains a mystery.

Back to the story noted above, about the group of South African DX’ers who were among the few worldwide to have heard Tristan da Cunha.

In that article, the author notes that two other DX’ers, one in the U.S., one in Europe, had received QSLs from Tristan.

With a bit of online sleuthing, and help from some fellow DX’ers, I was able to determine that one of those two, Dave Sharp, is indeed still with us.

In response to an email inquiry, Dave provided the following history:

“I forget when exactly I heard the station, but it was 1984 or just prior, as I was still in high school. I was in Florida at the time and was using a rotatable three element beam ham antenna. [I] heard threshold talk from a woman with a deep voice and this apparently matched to voice of the Radio Tristan announcer at the time.

[I] received a reply from Pat Patterson, the Tristan postmaster and a Ham radio operator himself. Since my reception report was tentative, I felt a QSL wouldn’t have been issued if they hadn’t been reasonably confident of reception.

I received a personal letter, stamp bulletin, and a small QSL, bright green on white background, with “ZOE” across the front.

Long story, but many of my personal belongings were lost over the years and this includes my entire QSL collection (which had been left in possession of my sister).

Needless to say, I received a fair bit of ridicule after coming forward with the QSL. To emphasize, my report was tentative and they decided to issue a reply.”

It remains to be seen if other ZOE/Tristan da Cunha QSLs will surface in the future, and of course it is unknown how many of the cards that were sent out to the few DX’ers who heard, or claim to have heard, the station, still exist.


Wow! Thank you for shedding light on the history of ZOE Tristan Da Cunha QSLs. At those meager power levels, from such a remote location, and during that broadcast window, I can see why ZOE must be one of the rarest of QSL cards. I’m happy to know you obtained the card, too, Dan as you have such a long history of properly archiving and sharing your cards. As you just did.  Thank you!

Hear My Voice: Radio’s role in Hitler’s annexation of the Sudetenland

In January, when I first heard about David Vaughan’s book Hear My Voice, I knew then and there I would have to read it. So I picked up a copy on Amazon with the intention of doing so…well, soon.

However, I’ve got quite a number of books in my to-be-read stack at the moment, so Hear My Voice lay in wait on my bookshelf until this past Sunday, when I decided to read the first chapter––just to get a taste of it.

Although I had a very busy day in store––working on a home renovation and making several trips into town––nevertheless I struggled to pull it from the stack, and having rapidly consumed the first chapters, had a hard time putting the book down. By the day’s end, I found I had read the entire book.

While those who know me know I’m a bit of a WWII history buff, I only knew that Hitler’s seizure of the Czech Sudetenland was but a hint of what was to come. The history I’d read previously had provided a bit of insight into this crucial lead-up to the war, but not as Vaughan’s book does: in what feels like a first hand account, through the eyes of an interpreter and broadcaster. I was hooked.

Hear My Voice clearly indicates how transformative the medium of radio was in this era, and how deliberate and insidious Nazi propaganda became in the Sudetenland years before Czechoslovakia ever took notice.

All in all, it’s a great read. I think you’ll find Hear My Voice as intriguing as I did.
