Shadows of the State: a photobook about numbers stations

RAF Akrotiri, Cyprus (Source: Lewis Bush)

Many thanks to SWLing Post contributor, James Jordan, who shares a link to this article in Wired magazine:

IF YOU TUNED into just the right shortwave radio frequency in the 1970s, you might hear a creepy computerized voice reading out a string of numbers. It was the Cold War, and the coded messages were rumored to be secret intelligence broadcasts from “number stations” located around the globe.

Photographer Lewis Bush is obsessed with these stations to “an almost irrational degree” and hunts them down in Shadows of the State, featuring 30 composite satellite images of alleged number stations from Germany to Australia. The series took two years and endless research. “It’s a difficult project to quantify in terms of man hours wasted on it,” he says.[…]

When Bush finds what he believes to be a station, he takes up to 50 close-up screen grabs and stitches them together in Photoshop to create one high-resolution image. He also listens to frequencies where broadcasts supposedly still happen on radio listening software, taking screen shots of the software’s spectrograms, graphics depicting the sound spectrum.

The final images try to visualize something largely intangible. No government has ever confirmed the existence of numbers stations, and Bush himself isn’t completely certain of their locations. No one can be sure what these scratchy codes really are. And that’s precisely what makes them so intriguing.

Shadows of the State will be published by Brave Books in December 2017. Bush is also raising funds on Kickstarterfor an interactive companion website.

WRMI: An update from Jeff White

(Source: Jeff White)

Dear WRMI Clients, Listeners and Friends:

Yesterday evening, Hurricane Irma passed very close to Okeechobee, and tropical storm force winds hit our transmitter site. I’m happy to say that the transmitter building and the transmitters themselves survived with no major problems. In the antenna field, one of our 44-degree antennas beaming up the East Coast of North America and over to Europe and the Middle East was knocked down, and may not be repairable. Fortunately, we have four other antennas beaming in the same direction, so we can continue those transmissions when the power comes back on. There are also about 20 telephone poles holding our transmission lines that are down or leaning, and they need to be repaired.

WRMI transmitter building with windows and doors boarded up in anticipation of the arrival of Hurricane Irma.

At this point, Florida Power & Light has no estimate of when power will be restored to our site. It could take days, or possibly even weeks. But we should have a better idea about this within the next few days. In the meantime, all transmitters are off the air, although our webstream with the 9955 kHz programming is operating. You can find it on our webpage, www.wrmi.net. There is an audio player in the lower right corner which you can click on to hear the programming. This stream is also carried by TuneIn, Streema, Radio Garden and other similar services. So please continue to upload your programs to our FTP servers as usual.

For WRMI clients, please be assured that we will put a credit on your next invoice for any of your programs that do not air on shortwave.

We do have a generator at our transmitter site which powers our control room, offices, lights and computers. Unfortunately it is not powerful enough to operate our fourteen 100,000-watt transmitters.

All of our staff are safe. Half of them were at the station during the storm (with some of their pets as well; we had two dogs, a bird and a turtle), and the others stayed in their own homes throughout the area.

I want to thank everyone who has called, e-mailed and sent messages with their prayers, best wishes and offers of assistance. We greatly appreciate all of them, and I will attempt to answer all of these messages personally in the coming days. The hurricane has dealt us a serious blow, but we will recover quickly and we’ll continue to broadcast your programs to shortwave listeners around the world. Thanks for your confidence in WRMI, and I will update you when we have more news.

Jeff White
General Manager

Jeff, we’re all wishing you the best as you work to put WRMI back on the air!

WRMI: Hurricane Irma has done “extensive damage”

(Source: WRMI on Facebook)

1430 UTC Monday, September 11

Hurricane Irma has done extensive damage at WRMI in Okeechobee, Florida.

Two antenna towers are down and many poles holding transmission lines are also down.

Power went out at around 2030 UTC Sunday, and it may not be restored for days.

Meanwhile, all transmitters are off the air. Our Internet service is also down, which means that our live stream is down as well. All of our staff are OK. We’ll try to provide more information later today here on Facebook. Thanks for all of your messages of support.

How to fix the Grundig S350DL’s mechanical tuning drift problem

The S350DL may look like a digital radio, but it’s actually analog inside and tuning is prone to drift.

Many thanks to SWLing Post contributor, Ed, who noted my comments about the Grundig S350DL’s tuning drift yesterday, and shared the following fix found on Jeff McMahon’s Herculodge blog.

Ed writes:

The Grundig S350DL’s mechanical tuning drift problem is reportedly easily correctable with a screwdriver:

(Source: The Herculodge)

[…]The drift on AM was terrible! After 10 minutes, it is jumping all over the place – if you touch the radio, the sound mutes and the display goes nuts. I pack it up to take it back but then I decide to google the problem and find this:

http://groups.yahoo.com/group/Grundig-S350/message/4644

I do exactly what he says – I pull off the cover after unscrewing all of the screws (including the 2 in the battery compartment).

Only the speaker is attached to the front. I remove the three screws from the display and then tighten the two screws on the tuning wheels. They were barely loose – almost not noticeable – so I was not too optimistic. I carefully got it all back together (the plastic pieces that hold the fabric handle on only go back on one certain way and were sort of a pain!). I cross my fingers, plug it in, and wow – a brand new radio. The tuning is perfect. Zero drift on FM and AM. AM sounds excellent.[…]

I have an earlier Grundig S350 that I bought at a hamfest years ago which had an easily-fixed power problem. For $20 it makes a nice bathroom radio and it sounds great, especially on FM.

BTW, I found schematics for it on radiomuseum.org, which is a great resource for radio schematics.

Thanks for the tip, Ed! I think I’ll crack open my S350DL later today and give this a try!

Zello transformed Holly from onlooker into dispatcher

As a follow up to our previous post about the PTT “radio” app Zello, SWLing Post contributor, Aaron Kuhn shares this story from The Houston Chronicle:

I downloaded an app. And suddenly, was part of the Cajun Navy.

After watching nonstop coverage of the hurricane and the incredible rescues that were taking place, I got in bed at 10:30 on Tuesday night. I had been glued to the TV for days. Every time I would change the channel in an attempt to get my mind on something else for a few minutes, I was drawn right back in.

I finally turned off the TV and picked up my phone to do a quick check of email and Facebook. I read an article about the Cajun Navy and the thousands of selfless volunteers who have shown up to this city en masse. The article explained they were using a walkie-talkie-type app called Zello to communicate with each other, locate victims, get directions, etc. I downloaded the app, found the Cajun Navy channel and started listening.

[…]As I was listening, I quickly figured out that there were a few moderators on the app that were in charge and very experienced in using this method of communication during emergencies. One in particular, Brittney, was giving directions, taking rescue requests, and prioritizing calls and rescues. At one point, she said something that made me realize she’s a nurse, so I immediately understood why she was so effective in this situation.

A couple of other women (who were working from other parts of the country, not Houston) who had been taking calls from victims and logging in the information came on the line around 12:30 and said they had to sign off so they could get to bed. They asked if there was anyone who could work through the night to keep taking rescue requests and log them.

I sat up and turned on my light. I timidly pushed the “talk” button and said, “I can.”[…]
