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 Mike Terry, Tracy Wood, John Palmer, and Greg Jasionek for the following tips:

SpaceX Launches Latest Satellite For SiriusXM Radio (Spaceflight Insider)

On Sunday December 13, a SpaceX Falcon 9 rocket successfully lifted off from SLC-40 at Cape Canaveral Space Force Station in Florida, carrying the SXM-7 satellite to a geostationary transfer orbit. The flight came two days after SpaceX’s first launch attempt on Friday, which was aborted at t-minus 30 seconds. The company tweeted the reason for the scrub, “Standing down from today’s launch attempt to perform additional ground system checkouts.” While SpaceX did not point to a specific reason for the hold call, it can be assumed that either the onboard computers or ground controllers found something off-nominal in the final seconds before liftoff.

[…]The payload, the SXM-7 satellite, is the latest addition to Sirius XM’s constellation of satellites aimed at delivering an extensive library of music and entertainment to most parts of the world. SXM-7, along with its sister satellite SXM-8 launching in 2021, are aiming to replace the company’s aging XM-3 and XM-4 satellites. Contracted and built by Maxar for Sirius XM, the 7,000 Kilogram satellite is based on the SSL-1300 Bus and utilizes a host of S band transponders to provide satellite radio to customers in North America.

“Maxar and SiriusXM have worked together for more than two decades to build world-class digital audio radio satellites that bring entertainment to almost every new car in America,” said Megan Fitzgerald, Maxar’s Senior Vice President of Space Programs Delivery. “We are proud to have built the latest addition to the SiriusXM constellation and look forward to the launch of their next Maxar-built satellite, SXM-8, next year.”[…]

CHU, Canada’s Time Station (Radio World)

Look inside the facility that broadcasts voice time signals in two languages

It is nestled in a farmer’s field in southwestern Ottawa, Canada, in a protected area known as the Greenbelt, surrounded by miles of sprawling suburbia.

It is CHU, Canada’s own automated time station.

Operating from a 1940s-era transmitter building and three vertical antenna towers, CHU broadcasts automated voice time signals in both English and French 24/7.

Its broadcasts are transmitted on 3.33, 7.85 and 14.67 MHz, and are heard through central/eastern Canada and the eastern United States, plus many other areas of the planet on a regular basis.

CHU’s time service is operated by Canada’s National Research Council, with the station being remotely controlled from the NRC’s Montreal Road headquarters central Ottawa some 12 miles away. The time signals are based on CHU’s trio of atomic clocks on-site, which are constantly checked against the atomic clocks at NRC headquarters.

“We are equipped with 1960s-era 10 kW transmitters that have been highly modified over the years,” said Bill Hoger. He is the Research Council officer who maintains the unmanned station as part of his overall duties along with two other off-site technicians.[…]

ID-52 Apology and Notice of Production Delay (Icom)

Thank you for your continued patronage of Icom products.

Regarding the 144 / 430MHz dual band 5W digital transceiver “ID-52” released in October 2020, there is a delay in the supply of parts from external partner companies, and additional production is significantly delayed. We sincerely apologize for the inconvenience caused to customers and retailers who are waiting for ID-52.

We will inform you about the timing of resuming production as soon as it is confirmed.

We are doing our utmost to resume production as soon as possible, and we appreciate your understanding.

New Type of Broadcast Receiver (LinkedIn Post)

There has been a lot of testing over last few month, with the new working prototype AM receiver. It has taking almost two years to get to this point with a lot of testing to find out what works and what does not.

The performance on Long wave and Medium wave is outstanding with the external loop configuration, this has many advantages over a ferrite rod antenna design. The Short wave performance is OK, where the front end RF transformers need to be improved with more testing. It out performs my Tecsun PL-398 that uses Digital Signal Processing (DSP), and comes close to what is possible within the high noise floor that you get in buildup areas.

The adaptive processing works very well, where you can set in software to work based on the signal level and if there is a pilot tone been detected (stereo indicator), this works for both the AM bands and for FM. As with the adaptive processing the noise reduction also works with both AM and FM bands, that has been use with Short wave and Long wave stations. The de-emphasis cave is design for 50 ?s, to pass a wider modulation bandwidth through up to 12.5 kHz.

The Denon TU-680NAB has been the reference receiver throughout all the testing to get to this test point. As this was designed for the high end audio market in the 1990’s, to provide the best possible performance for HiFi systems of the day.

[…]This will be marketed as a high end broadcast receiver, the aim is to stay well clear of low cost products from China, that are all too common these days. This is a Canadian product, showing that there are many new ideas and what possible in this area of development. With all these advancement it possible to provide a high quality music programming using AM radio that sounds as good as FM, with the advantages of larger coverage areas.[…]

A first look at the new C.Crane CCRadio Solar portable self-powered AM/FM/Weather radio

17 Replies

I remember when I first laid hands on a self-powered portable radio. It was the Baygen FPR1 designed by the amazing Trevor Bayliss. The FPR1 was a large portable radio with a black plastic body, large front-facing speaker, and large hand crank on the side. It was a clockwork radio, meaning you’d use the hand crank to wind up an internal spring that would slowly release and provide enough dynamo power to bring the radio to life for a few minutes at a time.

The FRP1 had a very utilitarian feel to it and was incredibly basic.

After the introduction of the FRP1, radio manufacturers jumped on self-powered radio technology and we’ve seen many different designs and iterations on the market for nearly two decades.

Introducing the C.Crane CCRadio Solar

Back in October 2020, C.Crane sent me a pre-production sample of the CCRadio Solar to evaluate. This was before C.Crane had published their new print catalog that features the CCRadio Solar on the cover, so I really had no idea what to expect. I assumed it might be a refreshed version of the CC Solar Observer.

Man…was I wrong!

Most self-powered radios these days either look like a flashlight, a portable analog radio, or they sport “high tech” styling (like the FRX3).

I can honestly say that the CCRadio Solar is the first self-powered radio that my wife actually welcomed into our kitchen!

This is a huge.

Out of all of the radios I’ve owned or tested over the years, my wife only tolerated their temporary presence in our living spaces.

There have been a few notable exceptions:

The Tivoli Model One
Como Audio Solo
KLH FM Radio 1
Muzen OTR
and now the CCRadio Solar

The CCRadio Solar’s design is very simple and clean.

The radio body measures 6″ x 3″ x 2.25″ and weighs about one pound. It’s easy to hold in your hand, but is also incredibly stable on a surface due to its low center of gravity, flat base, and UV-resistant rubber perimeter/jacket. (Note that the rubber jacket is in no way associated with rubberized coatings found on legacy portables that could break down over time and become sticky.)

I can place the CCRadio Solar in a window sill and not worry about it getting accidently knocked off.

On the top of the radio, there’s a large built-in solar panel, power button, flashlight button, and band button (to toggle between FM, AM, and WX radio).

The solar panel is large for a radio of this size.

On the back, you’ll find a fold-out hand crank and battery compartment for the internal Lithium-ion rechargeable battery and optional three AA cells. Yes, this radio can be powered from standard AA batteries!

On the right side of the radio, you’ll find the volume control and a cover that protects the headphones, micro USB charging port, USB power-out port, Aux In port, and a mechanical switch that allows you to toggle between Li-Ion and AA batteries.

On the left side of the radio you’ll find the attachment point for the supplied hand carry strap (I haven’t attached mine), and the built-in LED flashlight.

CCRadio Solar features at a glance

Multiple power options:
- Solar
- Windup
- USB
- AA Batteries
Multiple bands
- AM
- FM
- Weather radio with an alert alarm
Auxiliary input allows you to use it as an amplified speaker
Five one touch memory buttons with a total of 50 presets
Clock
Alarm
Sleep timer
Rubber jacket is UV resistant

Impressions

This CCRadio Solar is a pre-production model and it’s my personal policy to not comment in detail about performance as this model comes from a very limited pilot production run.

Here’s what I can say…

This is one of the first solar radios I’ve ever used that actually works as a daily driver.

Since I took delivery of the CCRadio Solar, it’s primarily lived on our kitchen window sill. This window faces due south, so the CCRadio Solar gets ample opportunity to take advantage of solar charging.

I like to listen to the news when I cook, so the CCRadio Solar gets daily use. I’ve used it to listen to both my local NPR station and my “benchmark” distant NPR station on FM. I’ve also programmed a preset for my favorite daytime AM station which is a good 25 miles from my home.

This prototype, at least, shows promise in terms of its ability to receive distant stations with a great deal of stability.

Solar chops

Last week, I realized that I’ve never had to charge the CCRadio Solar via the micro USB port. I’ve been using it since October for up to a couple hours a day–the solar gain from our kitchen window has easily kept the battery topped off!

I wanted to test this further, so a few days ago I moved the CCRadio Solar to another south-facing window in our living room area. I hooked it up to our SiriusXM receiver via the CCRadio Solar’s AUX IN port. (FYI: when you insert an AUX IN source, the radio automatically switches to auxiliary input.) This SiriusXM receiver is typically paired with my CCRadio3 and plays a variety of stations throughout the day for hours at a time–sometimes from early in the morning until the early evening.

The CCRadio Solar has been doing a brilliant job of playing all day long just on solar power and at a volume level that is room-filling, though not too loud to be distracting. Most impressive!

I should mention here that the built-in speaker provides (surprisingly) pleasant room-filling audio. The audio isn’t as robust as, say, my CCRadio3 or KLH–obviously–but it’s good enough that my wife has suggested we start using the CCRadio Solar as the speaker for our SiriusXM receiver because it’s powered by the sun instead of the power grid. I’m in agreement with her: it works.

There are a couple of caveats here:

First of all, we’ve been having mostly sunny or partly cloudy days since I started running the radio all day long and
secondly, our home is passive solar so our south-facing windows, by design, do not have “Low-E” coatings that block UV rays.

I’m not sure if Low-E coatings affect solar panel performance, but I think it’s worth mentioning.

Summary

If this prototype CCRadio Solar is any indication of how the production units will operate–and, in theory, it should be–I think the CCRadio Solar will become a very popular radio in the C.Crane product line.

At time of posting, there is no product page for the CCRadio Solar on the C.Crane website. When they do add it, it should appear on their Emergency Radios page.

I believe the price is projected to be $99.99 US–which is on the high side of the self-powered radio market–but if the production units function as well as this prototype I think it’ll be worth it.

I believe C.Crane hopes to start shipping the CCRadio Solar sometime in the first quater of 2021. Since we’re still coping with all of the logistics issues of the Covid-19 pandemic, assume that date could change. I’ll continue to provide updates here in the SWLing Post. Just follow the tag: CCRadio Solar

Dan’s respect for Hammarlund and the SP-600 series

6 Replies

Many thanks to SWLing Post contributor, DanH, who shares the following comment in response to this news article from the Citizen Times featured in Radio Waves yesterday:

Here are my thanks to members of the Amateur Radio community and The News-Record & Sentinel for remembering the legacy of Hammarlund Manufacturing Company Incorporated. It is good to know that this part of our radio history is valued and preserved. I loved the newspaper article!

I have a few vintage Hammarlund radios including two Super-Pro models. The SP-600-JX-21 is one of my daily drivers. This relatively late production SP-600 is in stock condition with the exception of a half dozen electrolytic capacitors that I replaced mostly in the power supply. By the time this SP-600 was built in 1957 Hammarlund had replaced the short-lived black beauty electrolytes with ceramic disc capacitors. Like military and industrial users I upgraded the original nickel plated tube shields with IERC heat dissipating tube shields where possible. I also installed vintage GE No. 1847 long-life incandescent bulbs as direct replacements for the brighter (too bright, for me) No. 47 dial lamps.

Here are my two most recent reception videos of the SP-600. The first features reception of Radio National da Amazonia and the second is a brief operating demo of the SP-600. The loudspeaker used in both videos is a full-range vintage Jensen 10? with matching transformer from the 1950’s instead of a communications range speaker typically used with these radios. This makes a big difference when listening to broadcasts.

This old Hammarlund is still working pretty well.

RN da Amazonia

SP-600 operating demo

Wow! Thank you for sharing this, Dan!

I used to own an SP-600 myself and I do miss it. The only reason I sold it is I was struggling to find a spot in my very compact shack where I could keep it on the air as a daily driver, yet still have enough room to bring new radios and accessories into the shack for evaluation. Moving it around all of the time (especially higher on my radio shelves) was incredibly difficult as she’s a hefty girl indeed! I ended up selling the ‘600 to a good friend for a song. That’s okay because like you, I know he’ll keep her in prime operating condition and I can even pop by to visit when I wish! I do miss having the ‘600 in the shack, though. It was truly a champion MW receiver as well!

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Trevor, Dan Robinson, and the Southgate ARC for the following tips:

Ham radio operators honor legacy of Mars Hill company (Citizen Times)

During the 1950’s and ’60’s, when the Hammarlund Manufacturing Company had a factory just west of Mars Hill College, the town could have been considered a world center of advanced electronic technology. With a company motto of “Quality Without Compromise,” almost 90% of American WWII wartime military electronic equipment employed Hammarlund capacitors. They also built U.S. Navy search radar installed on aircraft carriers, battleships and cruisers.

Hammarlund was one of the three leading brands of radio communications equipment at the time, along with Hallicrafters and Collins Radio. These three companies dominated in providing state of the art electronics equipment to the U.S. military, large and small corporations, and to private individuals who had the means and taste to own the very best.

Hammarlund Radio initially operated out of New York City starting in 1910, in the early days of radio. They began consolidating all of their operations in Mars Hill in 1951, in a newly constructed facility that spread out to over 100,000 square foot on Hammarlund Drive — now named Hickory Drive. The site employed hundreds from around the area and their work lives on today. […]

FM Radio From Scratch Using An Arduino (Hackaday)

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if you want to listen to something more culturally relevant.

Receiving frequency-modulated radio waves is typically more difficult than their amplitude-modulated cousins because the circuitry necessary to demodulate an FM signal needs a frequency-to-voltage conversion that isn’t necessary with AM. For this build, [hesam.moshiri] uses a TEA5767 FM chip because of its ability to communicate over I2C. He also integrated a 3W amplifier into this build, and everything is controlled by an Arduino including a small LCD screen which displays the current tuned frequency. With the addition of a small 5V power supply, it’s a tidy and compact build as well.[…]

2016 Report Confirmed Problem of Political Bias At Voice of America (USAGM Watch)

by Dan Robinson

Trump USAGM CEO Michael Pack Was Attacked For Attempts to Focus on Problem

It was May of 2016 and Amanda Bennett was only a few weeks into what would become a nearly four year stint as director of the Voice of America, among the “plum” jobs in Washington, D.C.

Bennett was just getting her feet wet, and at the time was dependent on a group of longtime embedded VOA managers that she would at one point describe as a “fantastic leadership team.”

She had received fair warning, from former VOA employees and extensive reporting by the independent watchdog website BBG and USAGM Watch, of disturbing issues at VOA, located in what has long been one of the most dysfunctional of federal agencies.

Some VOA journalists were using their taxpayer-funded positions to engage in self-promotion and campaign for political causes, a fact little known to most Americans. VOA’s website and digital operations were plagued by failures in breaking news coverage, and inaccuracies in content.

Both VOA and what was then called the Broadcasting Board of Governors (BBG) were increasingly seen by U.S. lawmakers as moribund. A Republican-led and eventually bipartisan effort in Congress proposed major restructuring – there was little patience left on Capitol Hill where the agency was increasingly considered to be “broken,” “rudderless,” and “worthless.” President Obama signed the reform legislation in December 2016 to create a powerful agency CEO position and to make the BBG Board purely advisory.[…]

ARISS Slow Scan TV event (Southgate ARC)

An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) for late December. This will be a special SSTV event to celebrate the 20th anniversary of ARISS.

The event is scheduled to begin on December 24 and continue through December 31.

Dates are subject to change due to ISS operational adjustments.

Dave, AA4KN
ARISS PR

The Geminids – a reminder (Southgate ARC)

The Geminids are a prolific meteor shower caused by the object 3200 Phaethon, which is thought to be a Palladian asteroid with a “rock comet” orbit. This would make the Geminids, together with the Quadrantids, the only major meteor showers not originating from a comet.

They are the biggest meteor shower of the year, and normally occur between 4 December – 17 December.

The peak is expected on 14 December.

Expect FM “pings” and hopefully interesting dx opportunities.

Dockside DXing with the super-portable Belka-DX receiver

15 Replies

I’ve been on the coast of South Carolina enjoying a little R&R with my wonderful family.

We rented a vacation home on a tidal river just south of Charleston, SC and it was just what the doctor ordered. The location was gorgeous, the weather was amazing, and there was very little RF interference outside our home.

The best part? We had full access to a private dock.

I took a few portable radios on vacation (ahem…obviously!) but I so thoroughly enjoyed my time with the Belka-DX.

If you haven’t gathered already, I really appreciate simple radios for field operation and it doesn’t get much more simple than the Belka-DX or Belka-DSP.

The radio is so incredibly compact, durable, and a pleasure to operate–especially if cruising the broadcast bands.

On the dock, I didn’t have a place to easily hang a wire antenna, so I used the supplied telescoping whip antenna. It served me well on a number of listening sessions.

As 13dka pointed out in his brilliant review of the Belka-DSP, the Belka radios are so compact, yet pack so much performance, they smack of a little spy radio! On top of that, the chassis is incredibly durable. I can’t tell you how much I love this. My Belka receiver has been living in my EDC bag in a small zippered pouch.

I barely notice it in my bag–it take up almost no space and weighs so little–but in the back of my mind I know I have a portable DXing machine everywhere I go.

I have no fear of being damaged in my bag, either–the chassis protects it so well.

Since London Shortwave has sorted out how to make spectrum recordings using the Belka-DX I/Q out, you’d better believe I’ll be sampling spectrum as I travel the globe post-pandemic!

I didn’t have time to gather what I needed for making Belka-DX spectrum recordings on this trip, but you can be certain I will when I return!

I should add that one of the little joys about my dockside DXing spot this past week was watching dolphins swim by as I tuned to some of my favorite broadcasters. Bliss.
