CCrane’s new C. Crane CC Skywave 2 . . . and the OODA loop

By Jock Elliott, KB2GOM

A software glitch at a power station, a tree branch rubbing against a transformer, a geophysical incident, a weather event, even a civil society misadventure . . . It doesn’t take much for things to rapidly go to blazes. So what do you need when Really Bad Things happen?

Back in the 1970s, Colonel John Boyd, an air warfare strategist, came up with the idea of the OODA loop. Originally designed for air combat, the OODA stands for: Observe, Orient, Decide, Act. In other words, see what’s going on, understand how it relates to your situation, figure out what to do, then do it.  OODA . . . got it?

So when really bad stuff happens, once you get clear of immediate physical danger (if any), you (or me or anyone involved) need to do your OODA loop: see what’s going on, understand how it relates to your situation, figure out what to do, then do it.

And to execute your OODA loop, you need information, right?

Soooo, when the lights are out, the internet is down, and maybe cell phones aren’t working, you need an emergency radio to find out what’s going on. Rob, W4ZNG, endured three weeks without electricity on the Mississippi gulf coast as a result of Katrina. In Rob’s case, during Katrina, all of the local broadcasters were wiped out. There was a local low-power FM broadcaster who got permission to increase power to 1,000 watts and was broadcasting where to get food and water. There was a New Orleans AM station that was on the air, but all of its coverage was “New Orleans-centric.” After a few days, some local FM broadcaster, working together, cobbled together a station that they put on the air and began broadcasting news. Rob also began DXing AM stations at night to get additional news. I don’t think it is an exaggeration to say radio was Rob’s lifeline to what was going on.

So, at the most basic level, an emergency radio needs to receive AM and FM stations. If you live in the U.S. or Canada, you also want NOAA weather radio channels, and, if things are really horrible, the ability to receiver shortwave radio might be useful.

Recently I had a look at an excellent candidate for an emergency radio.  CCrane has brought out a new and improved version of their super-versatile pocket-sized Skywave radio, and they sent me one for review without charge.

The new radio, the CC Skywave 2, covers FM from 87.5-108.0 MHz, AM from 520-1710 kHz, National Weather Radio Channels 1-7, air band from 118-137 MHz, and shortwave from 2300 to 26100 kHz. Small enough to fit in a shirt pocket, the Skywave 2 measures 3 inches high, 4.75 inches wide, and 1.1 inches deep and weighs about five and one-half ounces before you insert 2 AA batteries. (It can also be run off an optional CCrane power adaptor that can charge optional NiMH batteries. The manual warns: DO NOT USE LITHIUM BATTERIES).

According to CCrane, improvements to the Skywave 2 include a new micro-USB connector for external power and battery charging, a better speaker with slightly more amplification, circuit noise reduction, long feet for better stability, and a socket for plugging in an optional wire antenna adaptor available from CCrane.

I found the Skywave 2 really easy to operate. At the simplest level, select a band, then press one of the up or down buttons, and the Skywave 2 will scan to the next strong station. There is also an ATS (automatic tuning system) that programs all receivable AM, FM, or shortwave stations to memory buttons. Just select the band you want (AM, FM, or shortwave), press the ATS button, and the ATS system will scan the entire band and automatically set all available stations in sequence 1-10. If there are more than 10 stations are available, then the remaining stations will be stored on the next memory page and so forth. Each band has its own set of memories.

Everything is clearly labeled, and a gold label above a button indicates that if you press and hold that button, the function labeled in gold will be activated. If you want to directly enter a frequency (once you have selected the band you want), you must press the FREQ button first, then punch in the numbers. Otherwise, pressing any of the number buttons will activate the memory assigned to that number. To store a station in memory, press and hold any number button for two seconds.

Although I have no equipment for formally measuring things like ultimate receiver sensitivity, I found the performance on all bands to be typical of what I have come to expect of CCrane radios: excellent.

Full points to CCrane for writing a superb manual. In fact, I’ve found that the manuals for all the CCrane radios I have owned or tested have been well-written. I don’t know who is writing those manuals, but a big thumbs-up for clear manuals that are easy to use. The Skywave 2 manual even includes a section on “Hidden Settings” . . . ya gotta love it! Well done.

One other thing deserves mention: the Skywave 2 comes with CC Buds Earphones. I found they fit my ears comfortably and sound great . . . waaay better than the cheap-o earbuds I bought at a big box store.

The bottom line is: the Skywave 2 is a pint-sized powerhouse, and I can easily recommend it for anyone who needs an emergency radio, a travel radio (it has an alarm you can set), a weather radio with alert, or an ultralight MW DXing radio, or who simply wants to have a lot of fun with radio in a small, easy-to-handle package (An aside, listening to air band is pretty entertaining).

I found the performance to be excellent (for the radio’s size) on all bands, comparable to the CCrane Skywave SSB 2 that I own. In addition, with the new model (and the optional adapter), you can now plug in an external long-wire antenna for longer-range reception. That’s just great and could prove really useful.

The chief difference between the Skywave 2 and the Skywave SSB 2 is that the Skywave SSB 2 receives single sideband signals, making it possible for the listener to hear amateur radio and utility signals (like transoceanic flight control) that operate in upper or lower sideband mode. In addition, the SSB 2 includes (as well as the radio, carry case, and ear buds) a shortwave antenna and the CC wire terminal antenna adapter. In addition, the SSB 2 also has some software capabilities not available on the Skywave 2. For example, on the SSB 2, the Automatic Tuning System can also be used on the AIR band, and once AIR band frequencies have been stored, the SSB 2 can scan them. You can find my review of the Skywave SSB 2 here: https://swling.com/blog/2022/11/checking-out-the-new-c-crane-cc-skywave-ssb-2/

To conclude: I sincerely hope you never have to “do” your OODA loop, particularly not when things are going to blazes, but if you do, the CCrane Skywave 2 just might be helpful in getting the information you need. And, in the meantime, it is a very enjoyable radio to use, and I can recommend it without reservation.

Poland’s Railways Halted by a Simple Radio Hack (Gizmodo)

he Polish Railway’s radio system was hacked on Friday and Saturday, bringing 20 freight and passenger trains to an unprecedented standstill. The hack, believed to be carried out by Russia, took advantage of a critical flaw in the railway’s radio security system, with the issue reportedly restored within hours.

An investigation into the cyberattack is underway, and the Polish Press Agency (PAP) reported that the radio signals sent to stop the trains were interspersed with a recording of Russia’s national anthem and a speech by Russian President Vladimir Putin.

Poland is an important transportation hub that brings much-needed weapons supplied by Western countries and other aid to Ukraine amid the Russian invasion, and Senior Security Official Stanislaw Zaryn told PAP: “For the moment, we are ruling nothing out.” He continued: “We know that for some months there have been attempts to destabilize the Polish state. Such attempts have been undertaken by the Russian Federation in conjunction with Belarus.”

Train services were reportedly restored within hours and the Polish State Railways said in a statement that “there is no threat to rail passengers” and the cyberattack only caused “difficulties in the running of trains.” [Continue reading…]

Code Kept Secret for Years Reveals Its Flaw—a Backdoor (Wired)

A secret encryption cipher baked into radio systems used by critical infrastructure workers, police, and others around the world is finally seeing sunlight. Researchers say it isn’t pretty.

FOR MORE THAN 25 years, a technology used for critical data and voice radio communications around the world has been shrouded in secrecy to prevent anyone from closely scrutinizing its security properties for vulnerabilities. But now it’s finally getting a public airing thanks to a small group of researchers in the Netherlands who got their hands on its viscera and found serious flaws, including a deliberate backdoor.

The backdoor, known for years by vendors that sold the technology but not necessarily by customers, exists in an encryption algorithm baked into radios sold for commercial use in critical infrastructure. It’s used to transmit encrypted data and commands in pipelines, railways, the electric grid, mass transit, and freight trains. It would allow someone to snoop on communications to learn how a system works, then potentially send commands to the radios that could trigger blackouts, halt gas pipeline flows, or reroute trains.

Researchers found a second vulnerability in a different part of the same radio technology that is used in more specialized systems sold exclusively to police forces, prison personnel, military, intelligence agencies, and emergency services, such as the C2000 communication system used by Dutch police, fire brigades, ambulance services, and Ministry of Defense for mission-critical voice and data communications. The flaw would let someone decrypt encrypted voice and data communications and send fraudulent messages to spread misinformation or redirect personnel and forces during critical times.

‘Radio quiet’ boxes will now power world’s largest telescope (Interesting Engineering)

Engineers have designed and built the first set of 24 Small Modular Aggregation RFoF Trunk, or SMART boxes.

Radio telescopes detect faint radio signals arriving from distant cosmic sources.

As a result, it is critical that the site is as silent as possible, meaning that it should be devoid of noise caused by any gadgets, such as Wi-Fi, mobile phones, telescope machines, and other electronic equipment, in and around the radio facility.

Noise interference of any kind can distort or block out these signals, making astronomical studies extremely difficult.

This is one of the primary issues a multidisciplinary team of experts recently tackled by designing an advanced “SMART box” to electrically power the Square Kilometre Array Low Frequency (SKA-Low) telescope in Western Australia.

SKA-Low is part of the upcoming world’s largest ground-based astronomy facility that includes one other telescope, which has been constructed in South Africa.

“The SKA-Low telescope will receive exquisitely faint signals that have traveled across the universe for billions of years. To detect them, the SKA-Low telescope is being built in a pristine radio quiet zone far from the interference created by modern technology,” said Tom Booler, Program Lead for Engineering and Operations at the International Centre for Radio Astronomy Research (ICRAR) of the Curtin University.

“It’s so radio quiet at the observatory site that the biggest potential source of interference is the electronics like ours, due to the proximity to the antennas. That meant our project had to meet the strictest radio emission requirements across the entire Australian SKA site,” Booler added in the official release. [Continue reading…]

FCC Reminds Stations to Check EAS Readiness (Radio World)

The FCC is reminding U.S. radio stations and other EAS participants to make sure the upcoming national EAS test is accessible.

As we’ve reported, FEMA will transmit the nationwide test at 2:20 pm EDT on Oct. 4 using IPAWS, the Integrated Public Alert and Warning System.

To make sure it reaches the most people, the FCC’s Public Safety and Homeland Security Bureau has issued a reminder asking participants to make sure they’ve upgraded their EAS equipment software and firmware to the most recent version; ensured that their equipment can receive and process the National Periodic Test code and “six zeroes” national location code; and otherwise complied with FCC rules.

Here is the text of the planned EAS message:

“This is a nationwide test of the Emergency Alert System, issued by the Federal Emergency Management Agency, covering the United States from 14:20 to 14:50 hours ET. This is only a test. No action is required by the public.” [Continue reading…]

Guest Post: A review of the Chaoyuan LC90 Hybrid Shortwave/4G/Internet Radio

Many thanks to SWLing Post contributor, Michael Ye (BD4AAQ), for the following guest post:


The LC90, a Great Radio Spanning Two Worlds

by Michael Ye (BD4AAQ)

It is an awkward era for radio receivers. Although technology becomes more and more advanced and increasingly sophisticated radios are made, there are fewer and fewer stations to listen to. But hardcore radio hobbyists, mostly hams and shortwave listeners, would not give up the hobby. They continue to look for and enjoy stations among noises in the airwaves. Although Internet radios have been around for a long time, I never thought seriously about them. Perhaps I was stubborn, but in my mind, radios were noises and noises were radios and it’s the stations among the noises that I enjoyed. Receivers without noises were hardly real radios.

Until I got my first full band radio with Internet features. The LC90 was a pleasant surprise, completely changing the way I look at radio receivers. The LC90, or “full band smart Internet radio”, is my first shortwave radio AND Internet radio in one. There may be other radios with Internet features, but I have heard of few receivers that integrate the traditional radio (shortwave in particular) and the Internet. The LC90 was launched in China in early 2023, and quickly became popular among hobbyists thanks to the unique combination. News has been confirmed that the overseas version of the LC90 will be launched later this year. It provides more options for users at a time when shortwave broadcasters continue to shut down transmitters and bid final farewell.

Chaoyuan Company

The manufacturer of the LC90 is Chaoyuan, an electronics company based in Shenzhen, China, known for mobile phone design and Hi-Fi equipment. In recent years they started to design and make radios. And they are serious about the business, too.

The LC90 full band smart Internet radio

The Radio at a Glance

The radio is of regular size. A computer mouse is placed in the picture above, so you have an idea of not only the radio’s looks but also its size. The exact dimensions are 200x122x40mm. Its weight is 640 grams. The radio has a built in 4G SIM card, with 3G prepaid data. You have to add credit to the card in time by scanning a QR code on the screen before the built-in SIM card expires. You can also use your own SIM card by inserting it to a slot at the bottom of the radio. And of course, you could use Wi-Fi at home.

Although the radio is a combination of the traditional radio and the Internet, it is very ingeniously designed and does not put off the user with too many bells and whistles – you could press the tuning button to change the shortwave band and the fine tuning button to change the band width. The tuning button also serves as an “enter” key. These are clever designs that effectively save extra buttons. I have not seen a similar design in other radios.

For those who do not read Chinese, the upper five buttons are, roughly, “Configure”, “Timer”, “Setup”, “History” and “Favorites”. The four buttons on the left: “Confirm”, “Stations”, “News” and “Menu”. The four buttons on the right: “Back”, “Sequence”, “Rewind” and “Fast Forward”. The button with a globe says “Internet”.

The radio has excellent audio quality, rich bass, with a well-balanced frequency response. It is powered by two 18650 rechargeable lithium batteries. The radio has no back stand.

Traditional Radio

All three modes (or bands) are available, FM, MW and SW, as shown in the three buttons on the upper right (to get LW just press MW again). The FM band covers 64-108MHz, which includes Japan’s FM band. During the FMDX season you could have stations from Japan and other countries to explore. The SW band covers 2300-26100KHz, continuous, almost the entire shortwave band, more than enough for broadcast listening. The antenna jack works for all three modes (or bands).

Excellent Shortwave Performance

As a shortwave listener of many years, I am most interested in the radio’s performance in shortwave reception. Well, it is indeed very good in terms of sensitivity, selectivity and audio quality, with no compromise although the radio has an Internet section which requires additional space and resources.

When you use the radio indoor, reception could be poor and you can insert an external antenna to the antenna jack. Unfortunately, I cannot connect my AOR LA400 loop antenna to it as the antenna jack is too close to the tuning knob and so there is not sufficient space for the plug (see picture). Generally, a 3.5mm plug with a wire should work well if you extend the wire outside.

The external antenna jack

If there is a disappointment, its shortwave reception does not decode SSB signals. If the user is not a ham radio hobbyist, SSB reception may not be really needed anyway and the buttons, circuits and space can be saved accordingly.

Fair FM Reception

FM reception is good, but there is no obvious improvement of reception when an external plug is inserted in the antenna jack.

Mediocre MW Work

Reception on the lower bands, e.g., the medium wave band, is always a challenge in cities. It is not surprising that medium wave performance of the LC90 is mediocre at best. I don’t do much MW DXing but nowadays for each MW frequency there is almost always an FM frequency. Let’s face it – we should perhaps forget about medium wave reception in cities where there is excessive low band EMI.

However, if you go outdoor with the radio, medium wave reception can still be a lot of fun. And, contrary to FM reception, an external antenna significantly improves its performance!

Internet Radio

Admit it or not, the best days of traditional radio are gone, and while we continue to have fun on the old time radio, we should not hesitate to embrace newer technologies such as the Internet. By launching the LC90 and combining the two, Chaoyuan has made a significant move.

The Internet radio is an integrator of many online stations on the Internet, and more. It is completely different from the traditional radio which receives radio signals transmitted on air. The Internet radio, which relies on the Internet, provides much better audio quality, no noise, customizable and replay-able.

If you want to kill time and look for signals from noises, turn to shortwave and enjoy DXing. If you feel like listening to solid content or enjoying noise-free music, the Internet radio is there for you. This Internet radio integrates major web stations in China and on that basis the user can further select and configure their own favorites. Among apps that are built-in is Ximalaya FM, the leading audio platform in China. Due to requirements of policies and regulations in China, the user does not have much discretion to include foreign stations in the radio. However, Chaoyuan has indicated that they are working in an effort to secure authorizations from Spotify, Alexa and Pandora which they hope could be incorporated in the overseas version of the LC90. The future overseas version is expected to give the user more discretion to include online stations of their own choice.

A closer look at the display of the Internet Radio

Two buttons, Ai1 and Ai2, are voice assistants. Activate and speak to them and the radio directly plays the content (Ai1) or displays their findings for you to choose from (Ai2).

Finally, this is a radio with the most accurate time. There is no need to set the time for it, as it is based on the Internet.

Radio Waves: Great Solar Storm of 1940, Hawaii DJ’s Lack Vital Info, Edison Claims AM/FM Audio Usage Surpasses YouTube, and Radio 4 Longwave Reception

The Great Solar Storm of March 1940 (Spaceweather.com)

This story is shocking. On March 24, 1940, a solar storm hit Earth so hard it made copper wires in the United States crackle with 800 volts of electricity. A New York Times headline declared that a “sunspot tornado” had arrived, playing havoc with any signal that had to travel through metal wires.

“For a few hours it completely disrupted all long-distance communication,” wrote astronomer Seth B. Nicholson in a recap of the event for the Astronomical Society of the Pacific. Radio announcers seemed to be “talking a language no one could understand.” The New York Times reported that more than a million telephone and teletype messages had been garbled: “Veteran electrical engineers unhesitatingly pronounced it the worst thing of its kind within their memory.”

So why have you never heard of this storm? Even in 1940 it was fairly quickly forgotten. World War II was underway in Europe, and the USA was on the verge of joining. People had other things on their minds.

Modern researchers, however, are paying attention. A team led by Jeffrey Loveof the USGS Geomagnetism Program just published a new study of the event in the research journal Space Weather. Their work confirms that it was no ordinary solar storm.

“It was unusually violent,” says Love. “There were very rapid changes in Earth’s magnetic field, and this induced big voltages in long metal wires.” [Continue reading at Spaceweather.com…]

A valued source of communication, Maui radio DJs grapple with lack of information (Hawaii News Now)

HONOLULU (HawaiiNewsNow) – From taking calls of desperation, to sharing what they know when they know it, local radio hosts have long been a valued source of communication, especially during disasters.

However in light of the recent fires, many on Maui have expressed concerns that information from the government in times of disasters is far too sparse and delayed.

Lines of communication remain severed with cell towers burned to the ground. That’s leaving radio as one of the few dependable sources of communication, which is putting added pressure on local outlets.

Veteran radio host Ed Kapoi of KISS took a call from Napili, North of Kaanapali.

“People are desperate. Babies need diapers and formula. The elderly need their medication,” one caller said through tears.

It just rocks you to your core it really does. It’s hard to take those kind of phone calls,” Kapoi said.

Fellow KISS radio host Brandee Carvalho added, “We hear their crying, their tears, their desperate pleas. It is real. It’s very real for me.” [Continue reading…]

Radio 4 gets a terrible reception over scrapping long wave amid fears older people will struggle with digital radio” (Daily Mail)

[Editor’s Note: Per Wikipedia, “The Daily Mail is a British daily middle-market tabloid newspaper and news website published in London.”]

Listeners have criticised Radio 4’s retreat from long wave amid fears that older people will struggle with digital radio.

The BBC said last year it will stop scheduling separate content for the long wave version of the station in ‘anticipation of the closure’ of the platform.

Programmes which are on long wave but not Radio 4 FM include Test Match Special, editions of the Shipping Forecast, the Daily Service and a longer version of Yesterday in Parliament.

These shows will be available on other platforms once separate scheduling for long wave ends next March.

It is expected that listeners will be directed to the digital BBC Sounds audio platform to find these programmes. [Continue reading…]

The new Sangean MMR-99 series emergency radio

Many thanks to SWLing Post contributor, Mangosman, who writes:

Thomas,

I saw the Radio World review of the Sangean MMR-99 (page 16).

As I usually do I go to the source which in this case is the Sangean website to find

    • Sangean MMR-99 FCC AM/FM and in the USA version Weather radio band.
    • Sangean MMR-99 which is the UK version which is AM in the MF band for 9/10 kHz channel spacing No Low Frequency (LW) band.
    • Sangean MMR-99 DAB which is interesting because it is typically DAB+/FM no AM or Weather Band.

Your posters around the world may wish to review this radio which is available on line and in retailers.

Thank you for the tip! Impressive that MMR-99 is IP55 rated and ruggedized. I like the fact they’ve also made regional variants of this radio even including DAB.

The US version of the Sangean MMR-99 is available on Amazon.com (affiliate link) for $89.76 shipped

Sometimes simple works . . . really well! Exploring the CCrane EP PRO

By Jock Elliott, KB2GOM

This particular adventure began about three weeks ago with an email from CCrane. “Timeless, Easy to Use with Long Range Radio Reception” the headline read. Further, the accompanying text promised: Comes with needle and dial tuning, one button for power, one button for a bright display light, and has no clock or alarm.  The radio in question was the C.Crane CCRadio-EP PRO.

The “Long Range Radio Reception” initially caught my eye, but the simplicity of an old-fashioned “needle and dial” – what I call “slide rule” – tuning” also appealed to me, so I emailed CCrane, asked them if they would like to send me one for review, which they did, without charge.

While waiting for the EP PRO to arrive, I examined the photos of the EP PRO on the CCrane website, and I noticed something peculiar: a switch on back for choosing between 9 kHz tuning steps and 10 kHz tuning steps. Whaaat?! Why in the world would you need such a thing on a radio with needle and dial tuning?

We’ll get to the answer to that question shortly, but first let’s take a tour of the CCrane EP PRO.

The case is a rectangle with rounded corners that measures 11.4″ W x 7.3″ H (8.4″ H with handle) x 2.75″ D and weighs 4.5 pounds without batteries. Starting on the left front panel, you’ll find a 5-inch speaker. To the right of that, there is the slide rule (needle and dial) tuning setup, with a small red light on the right side that illuminates when a station is found. Below that is a CCrane logo and further below is a switch for selecting AM (520 – 1710 kHz, 10 kHz steps; 522 – 1620 kHz, 9 kHz steps), FM (87.5 – 108 MHz), or FM stereo; a knob for adjusting bass, a knob for adjusting treble, and a knob for choosing between narrow (2.5 kHz) and wide (6 kHz) filter bandwidths.

On top of the EP PRO are a red POWER button, a black button for lighting the tuning dial, a flip-up carry handle, and a 36-inch telescoping antenna for FM reception. (Inside the case is a ferrite bar antenna – 12mm x 200mm (7.9″) long with CCrane’s Twin Coil Ferrite® technology.)

On the right side of the case at top is the tuning knob, below that a knob for fine-tuning the internal antenna for AM reception, and at the bottom a knob for volume. On the left side of the case, you’ll find a 1/8” stereo headphone jack, a line-in jack, and a socket for plugging in an external 6-volt AC adaptor which is provided with the EP PRO.

On the back of the radio is a hatch for installing four D-cell batteries (CCrane says it will run for about 175 hours at moderate volume with the dial light off), external antenna connections: spring loaded for AM and “F” connector for FM, a switch for selecting internal or external AM antenna, and the switch for selecting 9 or 10 kHz tuning steps.

That’s it. The EP PRO is almost Zen-like in its simplicity. There are no seek buttons, no automatic storage functions, no memories, no key pad. And there is a darn good reason for that. It turns out that the immediate predecessor of the EP PRO, the CCrane EP, was created by Bob Crane because his mother wanted a very simple radio that was easy to operate. The CCrane EP, a true needle and dial analog radio, was the result.

Bob believed that, besides his mother, there was a market for such a radio, and there was. Unfortunately, after a time, the analog chips necessary to build the CCrane EP became unavailable. As a result, the radio was redesigned internally using modern digital chips (essentially the same as those in CCrane’s model 2E and 3 radios) while keeping it simple and easy to operate. So inside what looks like an old-fashioned analog radio beats the heart of a high-performance digital radio that combines the high sensitivity needed to hear distant stations with excellent selectivity to block signals from the side.

In my view, the EP PRO is great fun to operate. In the predawn hours on a weekend morning with the rain falling softly outside, I started tuning slowly across the AM dial with the EP PRO in my lap. Near the bottom end, a couple of sports mavens were chatting about a pitcher who had a couple of rough two initial outings and then had “settled in.”

A bit further up the dial Dionne Warwick was telling me to “walk on by.” Then I ran into a music station competing with a talk show considering “the Bible, angels, and UFOs.”

Up the dial some more, apparently a good deal on a high performance car could be had at a dealership in Connecticut; then an air quality report for New York City, a female voice delivering a long discourse in French and so on up the dial.

I was impressed at the number of stations that the EP PRO was pulling in, and it brought me back to the simple joy of tuning around to see what’s on the air.

Each time a discernible station appeared, the red tuning LED would light up. As needed, I used the antenna tuning knob and the bandwidth selection switch to tweak the signal. The needle and dial tuning gives an approximate indication of where on the band the radio is tuned, so if you want a positive ID, you need to listen for a station ID or some other clue to the station’s location.

At one point I jumped to the FM dial and found I could easily pick up many FM stations even with the whip antenna collapsed. In all, I am of the opinion that both the AM and FM sides of the receiver are pretty “hot,” and at no time did I find myself wishing for an auxiliary antenna for more signal.  Further, the sound through headphones or the speaker is very pleasant indeed. In my mind, the relatively unadorned exterior of the EP PRO belies its outstanding performance. To stretch an analogy, it’s a nitro-burning funny car in the body of a Honda Civic, and you don’t have to be a genius to drive it.

If you’re looking for a high-performance radio that is easy to use and sounds good through speaker or headphones, the CCRadio EP PRO delivers the goods. For a content DXer like me, the EP PRO encourages me to tune around and discover the magic of radio all over again.

The pirate-radio DJ who took on Putin (The Economist)

Tens of thousands of ordinary Russians are joining the resistance

n a bedsit in Vologda, a Russian city 500 miles north of Moscow, a man sat at a desk surrounded by recording equipment.
