Review: The C. Crane Skywave SSB radio

When I worked on the best receive-only emergency radios guide — the kind that don’t need a license since you don’t transmit — there was one model at the top of my mind: the C. Crane Skywave SSB. Highly regarded by amateur radio enthusiasts and shortwave fans, this radio receiver picks up the common things you’d dial into in an emergency: local FM radio stations, AM stations, shortwave, airband, and it even lets you pick up high-frequency ham radio conversations.

A few weeks ago, I was reminded of how important it is to have a dependable radio when straight-line winds knocked out power in much of our county. We pulled out this C. Crane radio, easily found some stations, and felt confident that we would’ve known if a tornado was heading our way.

C. Crane Skywave SSB

At an MSRP of around $170, perhaps it’s overkill for a weather radio, but you’re not going to find a better receiver on the market. I’ve been blown away by its receive capabilities. The entire package can fit into a pocket and is powered by two AA batteries, offering up to 60 hours of runtime (70 if you listen via the included earbuds).

There is also the cheaper C. Crane Skywave without the SSB capabilities, for a more reasonable $90. Most people probably don’t need SSB — which lets you tune into HF ham radio transmissions — and can opt for the non-SSB Skywave. The HF stuff comes in handy when you’re trying to hear transmissions from really far away (100+ miles).


  • Most people can skip the more expensive SSB, but the extra money is worth it if you want more serious SHTF scenarios covered and/or expect to get involved in ham.
  • There’s no way to plug in an external antenna, but it does include a reel antenna that clips onto the built-in antenna, improving shortwave reception.
  • Has automatic tuning, which scans for all clear broadcast frequencies and automatically programs them into the radio.
  • The weather alert is set by holding a single button and can be set for 4, 8, or 16 hours.
  • Unfortunately, the Skywave SSB can’t tune into first responder frequencies or local VHF/UHF amateur communications.

What’s in the box

Everything you need except batteries:

  • The radio itself
  • A pleather carrying case
  • Earbuds
  • A retractable reel antenna

Most included earbuds are junk, but the C. Crane ones are very comfortable and sound great. The case might be fake leather, but it’s a nice inclusion and has openings for the headphone jack, tuning knob, and antenna. Unfortunately, the case is just big enough for the radio itself, with no room for the earbuds or reel antenna.

The inclusion of the reel antenna is another nice touch. It’s for boosting the reception of the radio’s collapsible antenna: you clip one end of the reel antenna to the radio’s antenna, unreel the wire, and clip the other end to the top of a window frame or a tree. It’s practically a necessity for serious shortwave listening.

Solid build quality and battery life

The radio itself is small but solidly built. Measuring 4.8″ W x 3″ H x 1″ D, it easily slips into a front pocket even while in the case. It has a headphone jack, wrist strap, tuning knob, volume knob, kick-stand, and a mini USB port. The mini USB port is for using the optional wall adapter to charge NiMH AA batteries. The C. Crane Skywave SSB does not accept lithium batteries, but regular disposable alkalines will power it for up to 70 hours.

The runtime is even more impressive when you consider that the radio never truly turns off unless you remove the batteries. Pressing the power button takes it in and out of sleep mode. The reason being is so you can turn the radio “off” while still taking advantage of the alarm and weather alert functions.

Finding something to listen to

The instruction manual is clearly written, and it’s one of the better instruction manuals I’ve read lately. Between the manual and the fairly intuitive controls, I had all of the necessary functions nailed down in a couple of hours.

To listen to regular AM/FM radio, turn it on and press the AM/FM button. One press puts you in FM mode and a second press switches to AM. Pressing the WX/SW/AIR button cycles between NOAA weather channels, shortwave radio, and airband.

You can move between frequencies a few different ways:

  • Using the tuning knob on the side. By default, it moves 0.10 MHz at a time but if you click the knob it switches to slow mode, which tunes 0.01 MHz at a time, which is more useful for shortwave stations.
  • The arrow keys on the front. Each press moves 0.10 MHz. You can press and hold either the up or down arrow to scan in that direction. The scan stops when the radio detects a listenable frequency.
  • Directly punching in a frequency by pressing the FREQ button and then typing the frequency on the keypad.

Shortwave is split into multiple bands and many shortwave stations, like WWCR, switch bands and frequencies multiple times per day. When in shortwave mode, you can press the Meter/Stereo button to cycle between shortwave bands.

Once you find a station you really like, you can program it into memory by pressing and holding one of the numbers on the keypad. Each mode has its own set of memory channels, except weather where the channels are pre-programmed. Memory channels consist of 10 pages, each with 10 channels. Between Airband, AM, FM, and shortwave, you can store up to 400 channels in memory!

There’s also a great feature called Automatic Tuning System to automatically program the radio. Switch to the desired band and press and hold the Light/ATS button. The Skywave will scan through the band and program each available station into a memory channel.

There are also a few features to help you maximize sound quality. Holding the Page/Tone button switches between music and voice filters. Pressing and holding the Meter/Stereo button switches between mono and stereo filters. For shortwave stations, you can press the Bandwidth button to change the bandwidth. Flip up the kickstand to reveal C. Crane’s recommended bandwidth settings:

  • Best audio: 6 kHz
  • Best legibility: 3-4 kHz
  • Best noise filtering for strong signals: 1-2 kHz

Skywave SSB filter suggestions

Of course, one of the major reasons to buy the C. Crane Skywave SSB is weather alerts. They’re easy to turn on: press and hold the AM/FM button which also doubles as the weather alert button. Continue to hold down the button to cycle between 16, 8, or 4 hours of alert monitoring.

While alert mode is engaged, you can either turn the radio off or use the radio as normal. The screen lights up and flashes alert every few seconds as it scans the weather channels for an alert tone. When the radio picks up an NOAA alert, it starts beeping and flashing. Unlike many other weather radios, it does not turn on to a weather station automatically, but if you press the Power button the radio will turn on already tuned to the strongest weather channel.

Crane warns that the weather alert mode consumes as much power as when the radio is being used normally, so you don’t want to leave it on all the time.

Tip: If you want to test the alert function on your weather radio, the National Weather Service sends a test signal every Wednesday between 11 AM and 12 PM local time. Turn on the radio’s alert function before then.

Is the more expensive SSB model worth it?

Let’s say an extreme event happens, like an electromagnetic pulse or a coronal mass ejection. Assuming your radio still works, you try to tune into local FM stations but receive nothing. But if you could tune into long-range shortwave broadcasts, you’d at least know if the event was worldwide or local.

Advanced ham radio operators work in the shortwave range, but in a mode called single sideband (SSB), which lets them transmit only on one half of a radio wave to go further with less power. But SSB requires special hardware or software to decode, which is what makes the Skywave SSB special. Listening in to HF ham conversations usually isn’t useful, but there are special emergency services that can be helpful, like the Hurricane Watch Net.

The C. Crane Skywave SSB is an advanced version of the C. Crane Skywave. The major difference is the SSB can decode single sideband transmissions sent by ham radio operators working in the HF bands.

Tuning into ham frequencies is trickier than regular shortwave frequencies and requires some ham radio knowledge. First, put the radio into shortwave mode and then press the SSB button. It takes a few seconds for the radio to switch over.

Once in SSB mode, you can press the Meter button to switch between ham bands. But it won’t put you exactly at the top or bottom of a band, so you have to be familiar enough with the bands to know where the traffic will be. For instance, if you’re on the popular 40-meter band, you’ll want to be between 7.125 and 7.300 MHz. (And if you want to know where the insane people hang out, it’s 7.200 MHz, the 4chan of amateur radio.)

Thankfully, page 10 of the manual lists ham frequencies to try, along with some other SSB tips.

You also need to know which sideband you have to be in for each band. The radio sets this automatically as you cycle through bands. For instance, it’ll set 40 and 80 meters to LSB, where voice comms happen on those bands and 20 meters to USB, again where voice transmissions happen. But if you wanted to connect the Skywave SSB to a computer to let it decode digital signals, you’d have to know that digital usually happens on the opposite band. For instance, on 40 meters, digital is USB.

Forget trying to use the scan or ATS feature on ham bands, they just don’t work well and will pass over many conversations. Your best bet is to tune to the bottom of a band, click the knob to put it in slow mode, and slowly dial your way up the band.

There’s also the matter of fine-tuning. Hams don’t always talk on nice, round frequencies. So if everyone sounds like a chipmunk or like they’re in slow motion you need to press the FINE TUNE button and dial in the frequency with the knob.

That said, the trouble is well worth it because the Skywave SSB’s receive quality is mind-blowing. I’m sitting here in my partially underground office, surrounded by electrical noise, and I’m able to pick up faint ham transmissions without even deploying the reel antenna.

But is it worth it for you? The original Skywave is $90 while the Skywave SSB is nearly double that at $170. If you didn’t understand this section about more advanced radio nerdery, stick with the cheaper one.

Here’s who I think the extra money is worth it for:

  • Ham radio operators, who can use the Skywave SSB to search for RF interference and test their rigs.
  • Anyone interested in HF amateur operation who isn’t sufficiently licensed or can afford an HF transceiver.
  • Anyone in an area where they could benefit from the Hurricane Watch Net.


The C. Crane Skywave SSB is a great radio, but nothing’s perfect. My biggest disappointment with it is that it can’t tune into VHF/UHF amateur radio frequencies. If you manually punch in such a frequency, like 146.52, it’ll return an error, which indicates that those frequencies are specifically blocked in the hardware.

In an emergency situation, local amateur frequencies will be much more interesting to follow than HF ones. Likewise, the Skywave SSB won’t tune into first responder frequencies, so you’ll need a police scanner to tap into those. (Unfortunately, many are encrypted these days, so scanners are often pointless.)

The clip-on reel antenna does an admirable job, but I wish the Skywave SSB had a way to connect an external antenna, like a BNC connector, which would let you pick up signals from even further away.

      Thanks for sharing, Josh!  Based on your emergency radio guide, I recently purchased the non-SSB version of the Skywave which, for the price, quality, and versatility, was well within the 20/80 principle.  More advanced preppers, however, may definitely find the SSB option to be worth the money though.

      A quick question:  If I just have access to the standard SW channels without SSB (2.3-26.1mhz wavelengths are covered by my Skywave), what should I be looking to listen to in terms of emergency broadcasting?  At this point, I haven’t really found much of anything on the SW bands–other than a couple of channels that sounded like might be broadcasting in Morse code–and am thinking I need to buy the reel antenna (not included with the non-SSB Skywave) to be able to pick up whatever is available without the SSB feature.

      A suggestion:  For Skywave owners (or prospective owners), I’d recommend against buying C Crane’s optional AC adaptor and instead buy a more versatile USB-C adaptor.  Since the Skywave’s USB port is a non-standard, hard-to-find size, I had to shop around at a couple of electronics stores but was able to find a 6′ cord for $20 that fits the Skywave and allows me to plug in to pretty much any computer, standard phone charger, or USB port in my truck.  And, as advertised, plugging in with USB does allow me to charge my NiMH AA rechargeables while listening.

        I don’t have specific frequencies to recommend. Shortwave stations are kind of come and go, and you may not be able to pick up the stations I can. In those types of situations, I would use ATS to automatically find and program the stations you can receive. Higher frequencies tend to work better in the day, lower frequencies at night.

        Thanks for your advice, Josh!  I’ll continue to play around with it and see what I can find.

        I read that this unit “does not accept lithium batteries.”

        My stash of batteries all look the same.

      Great review!

      • Let’s say an extreme event happens, like an electromagnetic pulse or a coronal mass ejection. Assuming your radio still works, you try to tune into local FM stations but receive nothing.

      You could also tune into an AM station (if it’s night-time).

      This is a good reason to keep a list of clear-channel AM radio stations handy. At night they blast out at maximum power and can be heard 1,000 miles away.

      Most of them are the type of station that reads 5 minutes of the news at the top of the hour.

      I went through the list one time and was able to bring in more than 30 stations between 100 and 900 miles away (I live in the Eastern time zone).

      The limitation is that you can generally only hear them when it’s dark out. Still, another tool in the toolbox.

        Thank you for sharing the great tip! I haven’t listened to very many AM stations over the years, if any, but I should explore those frequencies and see what I can reach and what they talk about.

        Thanks for sharing this tool, FD1329!  I’ve been scanning the AM channels the past few evenings and have been able to tune-in a number of clear-channel stations up to 1200 miles away–albeit with staticky reception, but still . . . And, I’ve even managed to tune-in a number of non-clear-channel AM stations up to 600+ miles away.  I’m currently in process of programming those with the best reception into my truck radio and compiling a list of channels available, which I’ll print out and laminate for safekeeping, just in case.

        One thing I’ve noticed, however, is that tuning in AM stations OUTSIDE of my local area is pretty much limited to my truck radio and my 1990s-era boom box.  The AM reception on the Skywave is pretty much limited to local stations.

        Any suggestions on how I might boost the AM reception my Skywave?  I’m wondering if the reel antenna, which is on my list of things to order would help with that, or if it’s just limited to shortwave reception.  If not, are there any other DIY or commercial AM antenna booster options that might help out my Skywave?

        Following up on my previous response:

        It looks like the C. Crane website provides these instructions for a DIY AM loop antenna.  Some additional Google searching turned up this video demonstration of a similar antenna.

        So I’m guessing the shortwave reel antenna won’t work for AM stations because, if it did, C. Crane would just recommend purchasing that product.

        On that note, has anybody done this type of project and, if so, what type of wire did you use or would you recommend?

        That looks like a fun and cheap project to make an antenna out of old wire. Thank you for sharing this Colorado Jones.

        From the looks of it, any insulated wire will do. I would just go to the hardware store and buy thin 14 or 16 gauge wire by the foot and experiment with various lengths and diameters of rolls.

      Lithium batteries work well in mine for 3 years now. The only caveat is that you must not press and hold the “BAND WIDTH” button for 1 second when the supplied external power supply is plugged into the USB port.

        What happens if you do press and hold that Band width button when connected to an external power supply?

      I was looking at the Skywave SSB, but now they are coming out with a Skywave 2. Has new features that I think will be a big plus. $200 is a lot, but I think for what it is, it will be well worth it.

      My current radios are Eton Elite 750, Tecsun PL-680, 380, and R9700X. 

      I have been out of listening for around 20 years, and getting back into it, things have really changed, and seems like a struggle to play catch up. So I am just going to keep things simple as much as possible. With all that’s going on in the world, I think alternate sources of information and news will be helpful if things go South.
