Configuring the “News Cruiser” for your emergency radio

By Jock Elliott, KB2GOM

Rob, W4ZNG, endured three weeks without electricity on the Mississippi Gulf Coast as a result of Hurricane Katrina.

When he and I spoke about his experience (and what any one of us might want in our “fertilizer hits the fan” radio kit), he mentioned that 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 broadcasters, 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.

Hold that thought for a moment.

A few weeks ago, Andy, W2SRA, pops up on the Radio Monitoring Net (which I run on Tuesday nights) with a list of “Rolling News” medium wave stations that can be heard at least some of the time from my location in the Capital District of New York State. Rolling news stations broadcast news ‘round the clock.

The list includes:

780, WBM, Chicago, IL
1010, WINS, New York City
1030, WBZ, Boston, MA
1060, KYW, Philadelphia, PA
1090, WBAL, Baltimore, MD
1130, WBBR, New York City
1500, WFED, Washington, DC

When I saw that list, I thought “This is a pretty good resource.”

Then a day ago, something clicked, the lightbulb went on, and I realized: “This is exactly the list of stations that I would want if I were in the same situation as Rob after Katrina, where my local stations were dark, and I wanted to know what was going on! I named the list: the News Cruiser.

So, in the predawn hours, I decided to put the News Cruiser list to the test. I plugged the frequencies into several of my radios, and here is what I found. With the CCrane Skywave SSB 2, the signals ranged from copyable with noise to marginal to uncopyable, depending on the station. With the CCrane CCRadio SolarBT the results were better, but often tough to copy. Neither of these radios has the ability to connect to a medium wave loop antenna through a direct wired connection, although they can be inductively coupled to a loop such as the Terk AM Advantage.

The CCrane 2E, a much bigger radio with a much bigger internal ferrite bar antenna, produced markedly improved results. All three of these radios can be powered by off-the-shelf AA or D cells, which I considered to be an advantage during an emergency.

Two other radios, the Qodosen DX-286 and the Deepelec DP-666, which are powered by rechargeable batteries, acquitted themselves quite well when hardwired to the Terk AM Advantage loop antenna, but I prefer radios that can accept off-the-shelf commercial batteries.

If you live in North America, you can create your own News Cruiser list for your emergency radio by consulting https://radio-locator.com/ and using the search function to find stations that broadcast in the “News” format.

Once you have assembled your list, test it out with the radio you would grab in an emergency and see how well they perform. You might find the perfect combination that you like or you might discover that there is some room for improvement.

In any event, I heartily recommend that every household has an emergency radio that can be easily deployed to discover essential information when the fertilizer hits the fan. The point is to discover what works for you and to discover it before it is needed.

Further, I would very much like to know what works for you no matter where in the world you are located. Let me know in the comments below.

CC Buds Solo: Two years into the mission . . .

Okay, okay, I can almost predict what you will be thinking: it’s not the most expensive piece of gear in your listening kit. But for me, headphones or earbuds that pipe the audio from my SW receiver or scanner directly into my ears is one of my most valued pieces of equipment.

Why? First, because I have a hearing deficit that headphones or earbuds help to overcome. Second, to preserve domestic tranquility, so my wife doesn’t have to endure the squeaks, squawks, and static crashes that are often part of the listening experience. (We Armchair Adventurers have to keep our priorities straight.) And third, to help me concentrate on teasing out faint signals.

So I am a fan of headphones and earbuds, but I have had a difficult relationship with them because the wires break. That’s right; until recently, all of the headphones or earbuds that I employed eventually failed because the wire/cable connecting the headphones or earbuds to the radio failed, either losing any signal entirely or becoming intermittent.

Two years ago, the folks at CCrane teased me with a marketing email that offered CC Buds Solo In-Ear Single Earbud with a cable that was Kevlar reinforced for “maximum durability.” Intrigued, I purchased the “buy two, get one free” deal because I knew, just knew, Kevlar-reinforced or not, the cable would eventually fail.

Well, guess what? The cable did not fail, not even a little bit, despite my treating it badly. (Once, while walking, the cable caught on a doorknob, yanking the earbud out of my ear and a small digital recorder out of my pocket. And that’s not the only time I have inadvertently done my best to render it inoperable.) Two years into the mission, I am still using the original CCrane solo earbud that I first unpacked. The second one is deployed upstairs for my horizontal DXing exploits in the middle of the night, and the third I gave to a friend. CCrane says the audio is “tuned for superior voice quality,” which works just fine for my purposes.

So the upshot, if you hadn’t guessed, is that I can heartily recommend the CCrane Solo Earbud. If you consult the original post, found here — https://swling.com/blog/2023/12/checking-out-ccranes-solo-earbud/ — you can discover some additional details and some of the reasons why I find listening with one earbud to be an advantage.

A HUGE difference . . .

It was a remark from Sebastian Schlüter in response to this post – https://swling.com/blog/2025/10/some-really-inexpensive-ways-to-perhaps-improve-your-shortwave-listening — that sparked today’s post.

He said:

If your RFI is really high, your best weapon is a magnetic loop antenna aka small receive loop. At home, my RFI is so high that I don’t benefit from a larger/longer antenna. For example: Using the telescopic antenna (75 cm) vs using 3m of wire. Reason is that the signal-to-noise ratio is roughly the same in both cases and that all of those very weak signals are below the noise floor anyway, and the ones that make it through the noise are already strong enough to be received with the telescopic only. Conclusion: In a high RFI environment, it’s not about maximising the signal strength but maximising the SNR. You need to find an antenna type that will pick up less of that RFI. A cheap and simple antenna for this is the small receive loop. For a start, you can use a cheap wire terminal with 3.5mm mono jack. Using a 1:1 balun further improves the result.

What really struck my eye was this:

A cheap and simple antenna for this is the small receive loop. For a start, you can use a cheap wire terminal with 3.5mm mono jack.

My CCrane Skywave SSB 2 came with a wire terminal with a 3.5 mono jack, I realized. I hooked it up to my 45-foot horizontal room loop (a single strand of insulated wire run around the top of window frames and bookcases in my radio shack), and then ran the following experiment.

Using the scan function on the Skywave SSB 2, I scanned the shortwave bands using the whip antenna, and then I did it with the loop plugged into the external antenna socket.

The results:

CCrane Skywave SSB 2

Whip antenna: 4 stations detected. Loop antenna: 13 stations detected.

Then I tried the same experiment with a Tecsun PL-880.

The results:

Tecsun PL-880

Whip antenna: 8 stations detected Loop antenna: 15 stations detected.

Clearly, Sebastian’s suggestion of plugging in a simple wire loop makes a huge difference. And, I should note, I didn’t play fair. I did the test while 3 scanners, an LED light, and two UHF/VHF ham transceivers were operating in the vicinity and probably generating RFI.

So now the question: I ran the experiment with a 45-foot simple loop. What do you suppose would be the minimum wire length for an effective simple wire loop? I look forward to your input.

Some really inexpensive ways to perhaps improve your shortwave listening

Just yesterday morning, I was reminded that sometimes really small things can make a significant difference SWLing. So here are some things that I found can make an improvement, particularly if you are using one of the modern shortwave portables with its whip antenna.

Turn off as many electronics as possible in the room where you are listening. Computers, scanners, LED lights and all sorts of other electronics can introduce digital “hash” into the airwave near your radio. Turning them off may reduce the noise floor. Remember, we are all about improving signal-to-noise: we want more signal, less noise. Yesterday, I was trying to chase some English language broadcasts and found that turning off a nearby police scanner made a significant difference. If weather permits, moving outside can make a huge difference.
Feel free to move the whip antenna of your radio to different orientations such as horizontal and various points of the compass. Again, yesterday I was unable to hear one particular station with the whip antenna vertical, but when I lowered it to nearly horizontal and pointed toward the south, the station was audible.

OLYMPUS DIGITAL CAMERA

If you are just getting started, try using the search/scan/seek function of your radio to see what broadcasts it detects. Remember, though, that the seek function will reveal only what it can detect, so you might also try it with your antenna in different orientations. (See number 2 above.)

OLYMPUS DIGITAL CAMERA

Try using a bigger antenna. If you radio came with an auxiliary roll-up antenna, try deploying it. One of my auxiliary antennas is designed so that the far end can be clipped to a curtain. Try different configurations and see which works best. If you radio didn’t come with one, it is easy to improvise: get yourself 20 feet of insulated wire and an alligator clip. Attach the clip to the wire, then clamp the jaws of the alligator clip to the whip antenna on your radio. Try different configurations. The only hard and fast rule is: never, EVER, deploy an antenna where it can fall on a power line or a power line can fall on it. And, if you deploy your antenna outside be sure to haul it in when lightning threatens. Don’t go nuts with the length of the wire . . . 20 feet will do. Carlos Latuff, whose radiofax and weatherfax interceptions often grace this blog, often uses a wire antenna that is just 3 meters long!

It is very useful to have a list of target frequencies, particularly since so many modern portables have a keypad that makes punching in a frequency as easy as using a calculator. I can highly recommend the charts produced by Harold Sellers of the Ontario DX Association. These include the World English Survey (a listing of English language broadcasts by time and frequency), Target Listening by Country, and Target Listening by Time. Just because a station is listed at a particular time on a particular frequency doesn’t mean that you will be able to hear it, but I find it fun to punch in the numbers and discover what I can You can be notified when each month’s charts can be downloaded. They are posted to the ODXA Facebook Group files section and also on three IO Group files section: ODXA, World of Radio and CIDX.

I hope these small suggestions will be of some help in making your listening better.

A bit more about batteries for emergency radios . . .

A friend, Bob, is a professional in the two-way radio business with deep experience and expertise. I mentioned to him this post and told him about my strong preference for radios that would run on off-the-shelf alkaline batteries.

He had a few things to say about batteries for emergency radios that I thought might prove instructive for those interested in the subject:

“Back in the day, NiCAD batteries were known to develop ‘memories,’ when they would be recharged without being fully discharged. The strategy with them was to allow them to fully discharge and then recharge them.” The best work-around was to have two batteries, one fully charged and ready to go when the current one went “dead”.

“By contrast, if you deep discharge a Lithium Ion battery, sometimes the charger will see the low voltage and will not try to recharge “believing” that one of the cells is dead. Best practices with Lithium Ion is to regularly exercise the batteries and not let them sit as they will deep discharge to a low-voltage level resulting in the inability of the charger to effectively recharge them

He adds, “To my knowledge, almost every single instance of a Lithium Ion battery catching on fire in the charger was because the charger used was not the one that came with the battery. Bottom line: use only the charger that came with the battery.”

Bob says his strong preference for rechargeable batteries is Nickel Metal Hydride, which don’t seem to develop a memory and can be stored in a charged state for many months.

He concludes: “The best bet for emergency radios that may not be used for long periods are alkaline batteries. They offer the best shelf life.”

And there you have it from a radio professional whose advice I trust.

Emergency radio? You bet!

Recently, this blog featured great coverage of the use of battery-powered radios during the recent blackout in Europe.

It was a serious business: electric power, cell phone networks, internet, all gone in a moment, followed by an instant information vacuum. Battery-powered portable radios and local broadcasters with backup power came to the rescue, providing information as they could.

You can find the SWLing blog coverage here:

And when Hurricane Helene slammed western North Carolina and eastern Tennessee, radio was an invaluable resource. It was two-way radio, but the point remains the same: radio can be of great help when the lights go out.

So, here’s the upshot: when the lights go out, the cellphone is mute, and the internet is down, you need a means of gathering information so you can figure out what’s going on and what actions you might need to take . . . and that means of gathering information would be a battery-powered radio capable of – at a bare minimum – receiving your local broadcasters on medium wave and/or FM, and, if you live in North America, also capable of receiving weather radio.

My strong personal preference is for radios that can be powered by standard-size (like AA, AAA, and D cells), off-the-shelf, readily-available, consumer-grade, non-proprietary batteries. Why? Because, during a long-duration emergency, when my standard-size rechargeable cells run out of juice, I can drop in some off-the-shelf alkalines and keep using my radio.

With that in mind, here are three radios that I like. All three deliver worthy performance on AM, FM and weather bands (and sometimes additional bands) and can be powered by off-the-shelf batteries. I have used all three over extended periods and can recommend them without reservation.

CCrane Skywave SSB 2

The CCrane Skywave SSB 2 is a radio that brings a lot of capabilities in a diminutive package (3” W x 4.75” H x 1.1” D). It can receive: AM: 520 – 1710 kHz (10 kHz Steps), AM: 522 – 1620 kHz (9 kHz Steps – International), FM: 87.5 – 108 MHz (Regular Mode), FM: 76 – 108 MHz (When 9kHz is Selected), Shortwave: 1711 – 29999 kHz, (Includes SSB Fine Tuning in increments of 10Hz, providing the ability to listen to long-distance ham radio communications), Aviation: 118 – 137 MHz with scan capabilities, and Weather Band with alert capabilities.

It will run for about 65 hours on a pair of AA batteries. It comes with an adapter that can be used to connect to a long-wire antenna for improved reception of shortwave and SSB signals.

The CCrane Skywave SSB was the first radio I purchased when I got back into shortwave listening, and I have employed it to monitor AM, FM, ham communications, air band, and weather alerts. It is a pint-sized powerhouse that delivers a ton of versatility, and I really enjoy using it.

CCRadio SolarBT

The CCRadio SolarBT measures 6 inches wide by 3 inches high by 2.5 inches deep and weighs just a bit over a pound with batteries installed. The CCradio SolarBT can receive AM (MW) band from 520 to 1710 kHz, FM from 87.5 to 108 MHz (76-108 MHz in expanded mode), and 7 NOAA Weather Radio channels from 162.400 MHz to 162.550 MHz. In my opinion, it provides a step up in performance on the AM, FM, and weather bands.

What really sets the SolarBT apart is the flexibility of powering it. There are five options: (1) an 18650 Li-ion 3.7 volt rechargeable battery which provides around 50 hours of playing time (the manual advises fully charging the internal battery before use), (2) 3 AA batteries (not included, but good for about 40 hours of playing time. Don’t use Lithium batteries, the manual warns.), (3) a 110 mA solar panel (park the radio in a sunny window to keep it trickle charged), (4) a wind-up dynamo generator (300-500 mA at about two rotations per second. 90 seconds of winding will power the radio for 8-13 minutes or will charge your cell phone enough to make a few quick calls), or (5) a 5-volt DC, 1000 mA micro USB cable or optional AC adapter.

To quote from my original review of the SolarBT: “The SolarBT may be small, but, in my opinion, it punches above its weight and provides excellent sensitivity for its size on the AM, FM, and weather bands. You might buy it as an emergency radio, but my guess is that you will soon discover the joy of DXing with it.”

CCRadio 2E

The CCRadio 2E is large – 11″ W x 6.5″ H x 4″ D – but very capable. The CCrane company calls the 2E its “flagship,” and I can see why: in my experience, the 2E delivers exceptional performance in receiving AM, FM, and NOAA Weather Band with Weather Alert. In addition, it can also receive the 2-Meter Ham Band, which could be a vital source of useful information during an emergency.

In normal operation, the 2E can run off house power. But when the electricity goes off, it switches automatically to four internal alkaline D cells (user supplied), which offer roughly 170 hours of operation at a moderate volume level with the display light and weather alert feature off.

When my sister-in-law admitted that she didn’t have an emergency radio, I gave her a 2E. Why? Well, in part because of the exemplary performance, in part because of the long duration on batteries, and in part because it operates much like a car radio. I found her favorite stations, stored them, selected the strongest weather station, and also found and stored the local ham repeaters. Then I explained it to her: “Press this button to turn it on, this button to select the band you want, then press the buttons on top to select the station you want.” Easy-peasy.

The 2E isn’t just an excellent emergency radio, it’s a really great general purpose radio that will please habitual radio listeners and delight DXers who hunt for distant stations.

What if . . .

I can almost hear what you are thinking: ‘Yes, that is all well and good, but what if I already have a radio that I really like that runs on rechargeable batteries?”

Fair enough. My answer would be: buy some additional batteries that fit your radio, charge them up, and make sure that you keep them topped up from time to time.

And if your favorite radio does not receive NOAA weather band and you live in North America, get yourself a dedicated weather radio to fill in the gap. I own and can recommend the Midland WR120 Weather Alert Radio. It offers excellent performance and very sophisticated alert programming options.

So get yourself prepared, radiowise, for the next emergency . . . and enjoy your radios in the meantime!

Just how hardcore are you as a DXer?

I received the following from a ham radio friend:

Greetings all!

I received an interesting opportunity for anyone capable and interested
in helping NYS DEC. This was aimed at Warren County, however I thought
hams in the Northern District surrounding counties could also assist,
particularly Saratoga and Washington counties:

We were recently contacted by a representative of NYS DEC, Fish and
Wildlife Division requesting the assistance of the amateur radio
community. The DEC will be releasing approximately 20 bats with
transmitters attached and hope to track them to their summer roosting
locations. They are scheduled to be released on April 22 at Hague, NY.
The frequencies for these transmitters will be in the 150-151MHz range
and are included below. They will emit about 35 pulses per minute. The
idea is to set up your radio to scan the frequencies (by entering each
one, or scanning from 150-151MHz in 1KHz steps). Should you get a “hit”,
note the frequency and cross it to the serial number of the transmitter.
Note the date and time and report it to me.

This sounds like a fun exercise and we will be helping the DEC as well.
If you think you will be participating, let me know. I’d like to report
back to the DEC representative with an approximate head county.

Thanks and ’73

Update:
The release date has been moved to April 22.
One thing I didn’t mention in the original emai l: the transmitters
will work for about 2 weeks. So please scan when and where you are able
to within the 2 week period. Also, many radios do not have the ability
to tune in 1 KHz steps so your radio may not be able to monitor all the
transmitters. Scanners may work. Regardless, do the best you can. If
you are planning to participate and haven’t already notified me,
please let me know so I can notify DEC how many stations will
participate. Finally, here is the data sheet sent by DEC to help log
any “hits” you might get. If you get any “hits”, please send
info to me no later than the following day.

Update:
The bats will tentatively be released around 2015 hrs. tomorrow April
22. IMPORTANT: the transmitters will be using CW, not FM as previously
thought. (This is completely my fault as I assumed 2m band to be FM)
Anyway, please change your mode to CW. I’m hopeful that we will get
some “hits”, especially from the folks to the South. Ashley Meyer,
the DEC representative, has agreed to do a debrief/presentation on
Monday, May 5 at 1915 hrs. I will be sending out a Zoom link a few days
prior.

Thank you all for your interest in this project.
