Radio Waves: Future of Radio is Relevant, Hams Commemorate KDKA, Listen to the Globe, and Sangean EU Pre-Order for ATS-909X2

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!

Many thanks to SWLing Post contributors Troy Riedel, Dennis Dura, Mike Hansgen, and Eckhard Hensel for the following tips:


The future of radio is real, relevant and multi-platform (Biz Community)

Exciting new technologies promise to make radio more accessible and engaging than it has ever been. This includes app-based platforms that enable broadcasters to engage with listeners like never before, software that lets producers edit sound as easily as a text document, and a ‘radio station in a bucket’ that turns a mobile phone onto a broadcast hub.
That’s according to radio futurologist James Cridland, who believes that while innovations like these point to a bright future for the over 100-year-old medium, it’ll take more than adopting cool new tech to succeed in the increasingly splintered and diverse arena that radio is evolving into.

“Radio is more than just AM and shortwave, more than big, old fashioned transmitters. Radio is a shared experience with a human connection,” he said during a recent webinar on the future of radio hosted by Fabrik, a South African-developed software platform for broadcasters and community groups.

“That shared experience is something that [streaming music service] Spotify can’t offer. It’s something that somebody’s CD player can’t offer,” he said, adding that this also applied to radio stations who just play non-stop music. “There’s no human connection there. There’s no real shared experience.”[…]

 

Radio Amateurs in Western Pennsylvania to Commemorate KDKA Broadcasting Centennial (ARRL News)

Pittsburgh radio station KDKA will celebrate 100 years of radio broadcasting in November, and Pennsylvania radio amateurs will honor that milestone in a multi-station special event. KDKA dates its broadcasting history to the airing of the Harding-Cox presidential results on November 2, 1920, and the station has been on the air ever since. The special event, which will involve the operation of four stations, will run through the entire month of November.

“More than 100 years ago, many experimenters started delving into a new technology known as wireless, or radio,” said Bob Bastone, WC3O, Radio Officer for the Skyview Radio Society in New Kensington, Pennsylvania. Bastone explained that many of those early pioneers were radio amateurs. “One hundred plus years later, many amateur radio operators are still contributing to wireless technology, while also serving their communities and enhancing international goodwill. Congratulations to KDKA Radio, also known in the early years as amateur radio stations 8XK, 8ZZ, and W8XK.”

Special event stations K3K, K3D, K3A, and W8XK will set up and operate at several locations in Pennsylvania during November. Stations will determine their own modes and schedules. Visit the W8XK profile on QRZ.com for information on certificates and QSLs.

What became KDKA initially began broadcasting in 1916 as amateur radio station 8XK, licensed by the Federal Radio Commission (FRC), the predecessor to the FCC. At the time, amateurs were not prohibited from broadcasting. The small station was operated by Dr. Frank Conrad, who was Westinghouse Electric and Manufacturing Company assistant chief engineer. The transmitter ran 75 W, and the broadcasts gained some popularity in Pittsburgh.

During World War I, amateur radio operation was suspended due to national security concerns. After the war, 8XK was reorganized as a commercial AM radio station, KDKA. The first transmissions of KDKA originated in a makeshift studio on the roof of Westinghouse K Building in East Pittsburgh.

Ham radio clubs participating in the centennial special event include the North Hills Amateur Radio Club in Pittsburgh — which is planning to operate from KDKA’s 1930s’ transmitter site, where an original tower pier still stands. A 1920s’ transmitter site, in Forest Hills, will serve as another operating location. In addition to the North Hills ARC and Skyview Radio Society, other clubs taking part include the Panther Amateur Radio Club, Steel City Amateur Radio Club, the Wireless Association of South Hills, the Butler County Amateur Radio Public Service Group, and the Washington Amateur Communications Radio Club.

Individual radio amateurs will operate from their own stations, and a small group of hams is planning a portable operation from South Park in suburban Pittsburgh.

Stations will invite the public to visit, while observing the required social distancing protocols.

“We amateur radio operators look forward to contacting thousands of other hams around the world to celebrate this huge milestone in the commercial broadcasting industry,” said Bastone. Contact him for more information. — Thanks to ARRL Public Information Officer and Allegheny County ARES Emergency Coordinator Bob Mente, NU3Q, for providing the information for this story.[]

Listen to the Globe (NY Times)

Radio programming from around the world is available on the internet or through apps.

Americans may not be able to travel the world because of the pandemic, but thousands of foreign radio stations are easily accessible online to bring the world to you.

For Dorothy Parvaz, a radio editor in Washington, D.C., foreign radio was her first introduction to the world beyond Tehran, where she lived until 12. “Listening to radio signals coming in from other countries was just like seeing the world in a way we couldn’t on TV, ” she said. “If I wanted to find music, I went to the apartment downstairs, where one of the kids always got a good signal somehow. We heard Pink Floyd for the first time together.”

First look at the new Xiegu GSOC Touch Screen Transceiver Controller!

Yesterday, I took delivery of the new Xiegu GSOC Touch Screen Controller which has kindly been sent to me by Radioddity on loan for a frank evaluation. [Thank you, Radioddity!] GSOC development has been closely watched by Xiegu owners since its announcement this summer.

To be clear: the GSOC is not a transceiver, it’s a control head for the Xiegu G90 and X5105. Readers might recall my recent review of the Xiegu G90.

The Xiegu G90

I’ve heard some GSOC reviewers on YouTube note that the GSOC may also work with the tiny Xiegu G1M transceiver, but I’m not sure how it could convey the I/Q information since I don’t believe the G1M has I/Q output (perhaps someone can correct me as I’ve never used the G1M).

Connecting the GSOC to the G90 is a simple process:

  1. Remove the G90’s control head
  2. Use the supplied 9 pin serial cable to connect the GSOC to the G90
  3. Connect the G90 I/Q out to the GSOC I/Q in with the supplied 1/8″ (3.5mm) stereo patch cable
  4. Connect the G90 and the GSOC to a power supply or battery (each unit has a separate power connection)

The GSOC Sports a Large Touch Screen Interface

No doubt, the best thing about the GSOC is the 7 inch color touch LCD screen. It’s a capacitive touch screen as well, so feels more like a tablet screen than a soft pressure-sensitive screen.

While it doesn’t seem to have the pixel density of some modern tables, the resolution is more than adequate for the task and is, frankly, quite attractive!

The GSOC has a large encorder with a finger dimple that “floats” as you turn the the knob (much like my Icom IC-756 Pro).

This firmware version does have a number of adjustable settings for the GSOC and transceiver–all are easy to use.

A huge bonus is that the GSOC sports two USB ports. I’ve connected my portable wireless Logitech keyboard/trackpad to the GSOC via one of the USB ports and it works brilliantly.

I find it’s much easier to use a mouse or trackpad to click buttons on the screen as some buttons–especially the cluster below the frequency display–are tiny and a little more difficult to accurately click/select with a finger.

Form factor

The GSOC form factor works well for tabletop operation. There’s a fold-out bail that tilts the display forward for very easy operation. In fact, the GSOC bail must be used because it also acts as a stand-off to give the serial cable and IQ cable room to be connected. I prefer this rather than having all of the cables exit one side of the unit, for example.

When everything is connected, there are quite a few connections and cables in play:

  • Two power cords (G90 and GSOC)
  • Microphone
  • CW Key
  • Serial Cable
  • IQ cable
  • Antenna cable (for the G90 body)

If I owned a GSOC, I would sort out a way to manage the cables better and move the G90 body off of my table to save space.

One note: while the GSOC has a dedicated microphone port, it does not have a CW key port.  Your CW key still needs to be connected to the G90 body.

Notes

Keep in mind, all of these notes only pertain to the initial firmware version:

  • Startup time is about 29-30 seconds.
  • Many features such as CW/Voice memory keyers, CW reader/decoder, audio recording, auto notch filter, and many others have not been implemented yet but will be in the next firmware release according to the manufacturer.
  • The pointer arrow shows on the display regardless if you’re making selections with an attached mouse or your finger.
  • There’s a latency issue with the CW keyer in this firmware version which makes it difficult to form CW characters properly so I can’t test CW functionality. I understand this will be fixed in the next firmware version.
  • I’ve noticed some images across the spectrum display (most notably on 31 and 20 meters. I believe this may be due to the I/Q signal being a little too “hot.” I’m not sure if there’s a way to adjust this with the current firmware.

At time of posting, there’s very little in the way of a manual for this radio. It was shipped to me with this quick operation guide (PDF).

Price

The GSOC retails for $550 US via Radioddity–which is more than the G90 transceiver (currently $430).

If you’re a fan of the G90 or the X5105, though, it makes for an attractive and useful addition in the shack. It not only adds features to the G90, but even an FM mode.  While the GSOC is certainly portable, I’m not sure I’d take it to the field often because it would require extra setup time, bulk and weight. In an extended field event like Field Day or a park vacation, it might be worth the extra weight and space as it will soon give you programmable voice and CW memory keying.

What I find most interesting about the GSOC, in fact, is that it’s a case in point about how our radio world is moving into a “modular” area where components like the transceiver, amplifier, and panadapter/controller can be swapped out.

Any questions?

The Xiegu GSOC is following in the footsteps of other rado products out of China these days in that they’re initially released with a basic set of features to get you on the air, but advanced features and adjustments/tweaks are made in firmware upgrades after production. Based on the success of the G90 and Xiegu’s attention to customer feedback, I assume many of the missing features will be added soon. I’ll take a deeper dive into the GSOC in the coming days and certainly note when firmware upgrades have been made.

If you have any questions about the GSOC feel free to ask in the comments section of this post. I’ll do my best to answer, but keep in mind I’m pretty much learning the ropes here without a manual!

Channel 292 testing new antenna on 9670 kHz

Many thanks to SWLing Post contributor, Harald Kuhl, who shares the following note from Channel 292:

Maybe you already noticed on our homepage, that we try to start using
our new beam on 9670 kHz, which will increase the radiated power to the
target area by more than ten times.

Tests transmissions start today; we are grateful for every reception
report you will send. We change the target area every 15 minutes, so it would
be very helpful, if you could monitor for two hours, when all target areas
would have been covered.

Thanks for the tip, Harald!

Listeners, please send reception reports to Channel 292: [email protected]

I wrote to Grace Digital https://gracedigital.com/ today, 11/2/2020 asking about the Reciva shutdown and here is their reply;

“Your presets will work until the URLS for the streams become outdated. Not all radios will be turned off at the same time. The Mondo will be in the last group to be terminated. The software is Reciva dependent, you can get all the details we have here:

Grace Digital Internet Radios manufactured between 2007 and 2017 will stop working

The internet radio station finding service used by our legacy internet radios is being discontinued by the 3rd party service provider. This will affect Grace Digital internet radios manufactured between the years of 2007 and 2017 including the original Mondo.

(Please note; the Mondo Plus, Mondo Classic, and Mondo Elite are not affected).

BELKA-DX: A Pocket-Sized Radio for Pocket Change

Well, not pocket change for most people, but I couldn’t pass up a clever headline!

I want to alert SWLing Post readers to a lower cost option for the new BELKA-DX than the Mobimax source: the ecommerce web site of Alex Buevky (EU1ME) who designed the radio.

In early February I bought the original BELKA DSP from the designer’s site, for a total of $117 USD. It arrived safely in 10 days to my Washington State address, with free tracked shipping included.

Yesterday I ordered the new BELKA-DX from the same web site, and the grand total was 340 BYN, or in US Dollars, $128, tracked shipping included.

If I had ordered from Mobimax, the total would have been 176.91 Euro, or $205.76 USD. That price includes FedEx shipping, the only available option to the USA.

Purchasing from the BELKA-DX designer’s web site in Belarus saved me nearly $78, and I’m confident I’ll receive this new model in about a week and a half as before (hopefully no COVID-19 related delays).

I had no issues this time or previously with my payment being “flagged” for security concerns. I used my PayPal VISA card and the transaction completed without issues.

For more information on this tiny powerhouse receiver, see Georges Ringotte’s (F6DFZ) brief review here on the SWLing Post.
