The update eliminates the “false signal peaks” (images) of the EP Pro, a tuning anomaly that was widely criticized at introduction of this model. In addition, a 9/10 kHz tuning step switch has been added, and Jay also reports that reception performance is improved on the high band of medium wave.

Many thanks to SWLing Post contributor, Gary DeBock, who shares the following notes from his Cook Islands Ultralight DXpedition:
Sunset on the Cook Islands
Aitutaki Sunset DX
Aitutaki in the Cook Islands had some dazzling sunsets, and [my wife] loved to take sunset pictures with her new phone. Of course, I participated as well. As a result, sunset DXing was pretty rare while on the trip, although 7 USA mainland stations crashed the Kiwi sunset skip DXing sessions later in the evening around 0700 UTC. None of the usual Vancouver-Seattle-Portland-San Francisco TP-DXing pest stations made it to the South Pacific, though– and I didn’t miss them a bit! 🙂
610 KEAR San Francisco, California (5 kW at 4,610 miles/ 7,419 km) “Family Radio for the West Coast,” Christian religious format received at fair level at 0835 UTC on 4-12:
1070 KNX Los Angeles, California (50 kW at 4.570 miles/ 7,355 km) Powerful (S7) level with “1070 Newsradio” ID at 3 seconds, followed by national news at 0730 UTC on 4-10:
1160 KSL Salt Lake City, Utah (50 kw at 5,144 miles/ 8,278 km) Powerful (S7) level with weather and station ID at 33 seconds, followed by public service ads at 0901 UTC on 4-12:
1170 KFAQ Tulsa, Oklahoma (50 kW at 5,642 miles/ 9,080 km) Strong signal over apparent DU English co-channel with “Coast-to-Coast” ID at 44 seconds; thanks to Richard Allen for confirming the broadcast of the program on the station at 0845 UTC on 4-12:

Checking out transoceanic DX propagation at an exotic ocean beach site can provide the hobby thrill of a lifetime– if a DXer is lucky enough to choose the ideal time, place and gear to make the chase. All of these fell into place in an amazing way during a 5-day trip to Aitutaki Island (2600 miles due south of Hawaii) with Ultralight radio gear, resulting in the reception of MW stations in India, Bangladesh, Mongolia and Cambodia– all at over 6,800 miles.
Because of extensive QRM from Australia and New Zealand the total number of Asian stations received was limited, but it was definitely a case of quality over quantity. Phenomenal gray line propagation around sunrise shut down Japanese signals almost completely, but boosted up those from the exotic countries in east and south Asia. Korean station reception was limited to the big guns, which was also primarily true for Chinese signals. Except for the ANZ pest QRM, the conditions seemed custom-designed for a west coast DXer to go after the exotic stations which rarely– if ever– show up in BC, Washington or Oregon (even though the Cook Islands’ distance to them is greater).
7.5 inch loopstick C.Crane Skywave SSB Ultralight
Ocean beach propagation at sunrise was strong enough to bring in both 693-Bangladesh and 1431-Mongolia at S9 levels almost every morning on my Ultralight gear, and allow both 657-AIR and 918-Cambodia to break through ANZ QRM on April 12th. No doubt many more of these exotic stations could have been logged except for Australian QRM on 576, 594, 872, 883 and 1566, but this only added to the thrill of the chase. The overall results were exceptional for a DXer using only a 7.5 inch loopstick Ultralight radio and 5 inch “Frequent Flyer” FSL– all designed to fit within hand-carry luggage, and easily pass through airport security inspections. Thanks very much to Alokesh Gupta, Hiroyuki Okamura, Jari Lehtinen, Chuck Hutton and Bruce Portzer, who all assisted in the identification of these stations!
657 All India Radio Kolkata, India, 200 kW (8,075 miles/ 12,995 km) Recorded by accident during a sunrise check of the Korean big guns at 1641 on April 12, reception of this longest-distance station went unnoticed until file review after return to the States. The female speaker (in the Bengali language) is the third station in the recording, after the female vocal music from Pyongyang BS and the Irish-accented male preacher from NZ’s Star network. Her speech peaks around 40 to 50 seconds into the recording. The isolation of the Star network at the 55 second point was done by the Ultralight’s loopstick, not by the propagation. Thanks to Alokesh Gupta for the language and station identification:
657 Pyongyang BS Pyongyang, N. Korea, 1500 kW Like most east Asian signals the N.K. big gun sounded pretty anemic in the Cook Islands. Its female vocal music at 1641 on April 12th shared the frequency with NZ’s Star network (Irish-accented preacher) and AIR’s female Bengali speaker:
693 Bangladesh Betar Dhaka, Bangladesh, 1000 kW (7,960 miles/ 12,810 km) Probably the biggest surprise of the DXpedition, with S9 signal peaks on 4 out of 5 sunrise sessions. Frequently snarling with the Oz pest 3AW, it usually managed a few minutes on top of the frequency each morning from 1630-1700 UTC. Exotic South Asian music was the usual format, and was very easy to distinguish from the talk-oriented format of 3AW (and other Oz co-channels). This first appearance at 1652 on 4-10 featured a “Bangladesh Betar” ID by a male speaker at 8 seconds into the recording (thanks to Chuck Hutton for listening):
774 JOUB Akita, Japan, 500 kW Oddly enough, this was the only Japanese signal making it to the island during the entire trip. Mixing with a goofy-sounding 3LO announcer at 1613 on 4-11, the Japanese female speech concerns a “doobutsuen” (a “zoo” in Japanese, similar to what the frequency sounded like with the 3LO announcer):
819 KCBS Pyongyang, N. Korea, 500 kW The N.K. big gun managed a potent signal for its 3+1 pips across its “TOH” at 1630 on 4-12 but never could shake off RNZ’s Tauranga transmitter:
909 CNR6 Quanzhou, China, 300 kW Strong signal with CNR ID (1:08) and Mandarin speech by male and female announcers. NZ’s Star network was apparently off the air at the time, since it was a real blaster when transmitting:
918 RNK Phnom Penh, Cambodia, 600 kW (6823 miles/ 10,981 km) Breaking through the Shandong and Oz QRM at an ideal time to dominate the frequency, its sign off transmission with the National Anthem peaked just before the 1700 TOH on April 12. Female speech in the Khmer language and exotic music are featured just before the anthem (thanks to Hiroyuki Okamura and Jari Lehtinen for listening, and identifying the National Anthem):
918 Shandong RGD Synchros (Multiple) The dominant Asian signal on the frequency, it rarely allowed Cambodia to sneak through. Here it is with female Mandarin speech at 1647 on 4-11:
Shandong RGD’s transmitters were poorly synchronized, resulting in the two-tone time pips at the 1700 TOH on 4-12 (during Cambodia’s National Anthem at 1:40, in the MP3 linked below). Although actually from two different transmitters, the sound effect sounds similar to that of a “cuckoo clock,” resulting in some initial confusion about their source:
972 HLCA Dangjin, S. Korea, 1500 kW The South Korean big gun played the part on most mornings, including this S9+ Korean female speech at 1631 on 4-12:
981 CNR1 Synchros Changchun/ Nanchang, China, 200 kW/ 200 kW The first of three CNR1 frequencies which usually produced strong signals, this music // 1377 was received at 1624 on 4-12:
1377 CNR1 Synchros (Various) Overall this was not only the strongest Chinese frequency on the band, but was the strongest Asian station on the band as well. Awesome S9+ signals were typical each morning, as with this male speech and music at 1622 on 4-12:
1431 Mongolia (Relay Station) Choibalsan, Mongolia, 500 kW This station was easy to receive on the first attempt, with very little competition on the frequency. It typically managed an S9 signal after 1630 daily with the BBC’s Korean service, which seemed to be broadcast during the peak sunrise enhancement time in Aitutaki’s ocean-boosted propagation. Here is BBC’s Korean male announcer at an S9 level at 1632 on 4-11, with the BBC interval signal at 47 seconds into the recording:
1566 HLAZ Jeju, S. Korea, 250 kW A very poor signal was typical during this trip, with the Chinese service barely showing up under 3NE and two other DU English stations (probably 4GM and Norfolk Island). Whenever 3NE was in a fade it had a chance, since other two co-channels were running very low power. Here is the latter situation, with the weak Chinese barely audible under the DU English snarl at 1641 on 4-12:
1593 CNR1 Changzhou, China, 600 kW This was another Chinese blaster, with S9 signals typical every morning. Here it was at 1641 on 4-12 with male Chinese speech and music at 1377:
Amazing, Gary! Thank you for taking us along on your excellent Ultralight DXpedition. With a modest portable radio and a little antenna ingenuity, you’re enjoying some outstanding DX! You’re living proof of the point I was trying to make in a post yesterday!
Many thanks to SWLing Post contributor, Gary DeBock, who shares the following note about his recent Cook Island DXpedition:
The farthest DX received during the Cook Island DXpedition (on Aitutaki island) was 657-All India Radio in Kolkata, India, at 8,072 miles (12,991 km). Recorded by accident during a sunrise check of the Korean big guns at 1641 on April 12, reception of this longest-distance station went unnoticed until file review after return to the States.
The female speaker (in the Bengali language) is the third station in the recording, after the female vocal music from Pyongyang BS and the Irish-accented male preacher from NZ’s Star network. Her speech peaks around 40 to 50 seconds into the recording.
The isolation of the Star network at the 55 second point was done by the Ultralight’s loopstick, not by the propagation. Thanks to Alokesh Gupta for the language and station identification!

Cook Islands (Aitutaki) Ultralight DXpedition from April 8-13
A gorgeous environment, with thrilling long range DX! Ruth and I took this trip as the 38th anniversary of out first meeting at Victoria Peak in Hong Kong (April 10, 1980).
DXing highlights were the reception of 693-Bangladesh, 918-Cambodia and 1431-Mongolia on the 7.5 inch loopstick C.Crane Skywave SSB Ultralight and 5 inch “Frequent Flyer” FSL antenna (designed to provide inductive coupling gain equal to that of a 4 foot air core box loop, but in a much more compact size).
693-Bangladesh 1652 UTC April 10 (mention of Bangladesh at 8 second point; thanks to Chuck Hutton for listening):
Location: Tamanu Beach Resort ocean shore, Aitutaki, Cook Islands (in the South Pacific)
Amazing catches, Gary–thank you for sharing! It seems your modified CC Skywave SSB is serving you well. Looks like you were chasing amazing DX from an amazing part of our planet!
UPDATE (05 November 2018): Please note that we have posted a second production run update to this initial review. In short, C. Crane addressed all of the major issues I noted in the review below. Click here to read the CCRadio-EP Pro update.
Without a doubt, C. Crane Company has become an established name in our radio community as a retailer and manufacturer that focuses on the world of broadcast listening. The company’s ads, website, and blog all promote broadcast listening as a viable and important part of our evolving media landscape. Their radio products are all designed with broadcast listening in mind.
The C. Crane CCRadio 2E
Currently the company manufactures one of the most capable AM broadcast receivers on the market: the CCRadio-2E.
The CCRadio-2E, however, is a pricey portable at $170 US, perhaps overkill for the casual broadcast listener.
So, for those seeking a simpler broadcast receiver, C. Crane later developed the original CCRadio-EP, a bare-bones, fully analog AM/FM radio with a large backlit slide rule dial, designed for the listener who wants to “go old school” in their receiving.
The original CCRadio-EP also attracted mediumwave/AM broadcast radio listeners because it had fairly impressive performance characteristics supported by C. Crane’s patented Twin Coil Ferrite AM antenna. In many ways, the original CCRadio-EP was somewhat reminiscent of the GE Superadio.
Yet while the original CCRadio-EP has––according to C. Crane––been a popular product, because certain vital EP components are now becoming obsolete, the company has been forced to redesign it; hence the new CCRadio-EP Pro.
The CCRadio-EP Pro: A different animal
Let’s be clear, though: unlike its predecessor, the CCRadio-EP Pro is no longer a true analog set.
Despite external similarities, internally this radio and its predecessor are very different receivers. Inside, the EP Pro is based on the Silicon Labs SI4734 DSP chip. Perhaps it goes without saying, but I consider the move to a chip a significant design change.
Crane kindly sent me a review sample of the new CCRadio-EP Pro. It’s important to note that the review unit came from a strictly limited first production run; the actual consumer rig’s first major production run is still a few weeks away. Thus this radio is not yet shipping.
I’ve had the CCRadio-EP Pro for a few weeks now, during which time I’ve given it a thorough evaluation. So, let’s take a close look at the CCRadio-EP Pro––first, in terms of performance.
AM Performance
Let’s face it: if you’re a radio enthusiast and reading this review, you’re likely mainly concerned with the EP Pro’s performance on the AM broadcast band. Personally speaking, that’s true for me, too.
The CCRadio-EP Pro (left) and Tecsun PL-660 (right).
Over the years of reviewing portable receivers of all stripes, I’ve learned that nothing beats a radio specifically designed for AM broadcast band performance. Without a doubt, C. Crane intends that the CCRadio-EP Pro be one of these radios. Indeed, in many ways, it’s an ideal set for broadcast listening, because it sports:
C. Crane’s Twin Coil Ferrite AM antenna
A large speaker
Wide/Narrow bandwidth switch
Dedicated external antenna connections
Although beefy internal AM antennas, large speakers, and external antenna connections were relatively common in the 1970s and 80s, these are rare features among modern AM/FM portable radios. The fact is, radios with superb AM broadcast performance are becoming a rather rare breed.
External antenna connections
In other words, the CCRadio-EP Pro has many design features that position it to be a formidable AM broadcast band receiver.
So, then, how does it perform? Well…that’s complicated to explain. The CCRadio-EP Pro has some positives, but also a notable amount of negatives.
Let’s start with the good news.
Positive: AM Sensitivity
Comparing the CCRadio-EP Pro (left) with the Sony ICF-5500W (right) and the Tecsun PL-660 (middle) at the Pisgah Astronomical Research Institute.
The CCRadio-EP Pro is quite sensitive on the AM broadcast band. When I’ve compared it with a number of shortwave portables I own, it almost always outperforms them on frequency. When my Tecsun PL-660––one of the most sensitive mediumwave receivers among my shortwave portables––is tuned to a marginal signal, it sounds about half as sensitive as the CCRadio-EP Pro.
The noise floor is fairly low while the audio is robust and room-filling via the EP Pro’s front-facing speaker.
Positive: No drifting
As I’ve said above, unlike the original (analog) CCRadio-EP, the EP Pro is a mechanically-tuned DSP radio. In all of my testing, I never noted a time that the radio drifted off frequency.
Positive: Nulling
Crane’s internal Twin Coil Ferrite AM antenna affords the listener excellent gain and nulling capabilities. In fact, I find the nulling quite sharp, a major positive for this listener.
Positive: Fine tuning control
On the right side of the CCRadio-EP Pro you’ll find a large tuning knob (top), the antenna trimmer (middle), and large volume knob (bottom)
Like the original EP, the EP Pro has a Twin Coil Antenna Fine Tuning adjustment.
This feature can help make small adjustments to received station to peak reception. This fine tune control is actually trimming the twin coil ferrite bar.
Positive: Wide/Narrow filter
The EP Pro does have a Wide/Narrow filter selection which essentially helps widen or narrow received audio. Note that this has no meaningful impact on the imaging mentioned below.
Altogether, this about sums up the CCR-EP’s positive performance capabilities on the AM broadcast band.
Now let’s look at the CCR-EP’s negatives, some of which are, unfortunately, significant.
The original CCRadio-EP revives the joy of a purely analog radio set. When you tune up/down the bands, there’s a fluidity to the whole process. While the interface is simple, analog tuning allows your ears to pick up on the nuances––the rise and fall of stations both strong and weak as you travel across the dial.
As we mentioned earlier, mechanically-tuned DSP radios, like the new CCRadio-EP Pro, may look like analog sets, but inside, they’re entirely digital. And one drawback to all of the mechanically-tuned DSP radios I’ve tested so far is a tendency to mute between frequencies. With each 10 kHz frequency step, you’ll hear a short audio mute. If you tune across the dial quickly, audio mutes until you land on a frequency. Here’s a video demonstrating the effect:
Needless to say, muting makes band scanning a more fatiguing process. It’s really a shame this affects the AM band. I hope that C. Crane engineers can minimize this issue in future production runs, but I understand much of this is a characteristic/limitation of this particular DSP chip.
Crane actually includes a note about weak images which you might find below and/or above your target signal. Weak images are an unfortunate reality of the CCRadio-EP Pro; they’re prevalent on both AM and FM.
Here’s how you’ll experience the images by way of example: let’s say you’re tuning to a strong local AM station on 630 kHz, noting that the EP Pro has 10 kHz tuning increments. As you tune to 630 kHz, you’ll hear the station on 620 kHz, though it won’t be as strong as it is on 630 kHz. Then if you tune to 640 kHz, you’ll likely hear a weaker image of the station there, as well. In my experience, images are present on both sides of the target station if the station is strong. If it’s a weak station, you might only hear it, say, 10 kHz lower but not above (or vise versa).
The CCRadio-EP Pro is powered by four D Cells.
As you might imagine, this poses a problem for the weak signal AM broadcast band DXer. Let’s say you’re trying to snag an elusive DX station on 640 kHz; although the EP Pro might have the sensitivity required to grab that station, it’s simply not selective enough (if selective is indeed the right word) to reject the local station on 630 kHz, thus your weak DX will have local competition.
This, more than any other negative, takes the EP Pro out of the realm of the mediumwave DXer.
I’ve also discovered that, on my unit, the top half of the AM dial is inaccurate. I estimate that the slide rule dial is off by about 40-50 kHz at the top end of the band. It’s much more accurate below 1,200 kHz, however.
Here is a few photo of the CCRadio-EP Pro tuned to 1600 kHz:
I hope C. Crane can address this in future iterations of the EP Pro. While I don’t expect slide rule dials to be extremely accurate, there nonetheless needs to be some reliability.
Note: C. Crane engineering is aware of this problem and even attempting to implement a fix on the first production run units. I will follow up when I learn more.
Negative Audio “pop” with power on
As you might have heard in the band scanning video above, any time you turn on the CCRadio-EP Pro, you’ll hear an audio “pop.” This is happening when power is applied to the audio amplifier. The pop is not soft, but fairly audible, and is present even if you turn the volume down all the way. The audio pop is prevalent via both the internal speaker and when using headphones. Fortunately, it’s much less pronounced via headphones. While not a major negative, I find it a bit annoying, and don’t doubt that other listeners will, too.
Note: C. Crane engineering tell me that they’ve minimized the audio pop since making the limited first production run, thus the first full production run should be improved.
Negative: AM frequency steps currently limited to 10 kHz
My initial production run EP Pro is limited to 10 kHz frequency steps. This radio is primarily marketed to North America where 10 kHz increments are standard. Of course, if you’re trying to use the EP Pro to snag Transatlantic or Transpacific DX, you’ll miss the ability to tune between those broad 10 kHz steps. But, again, due to the imaging mention above, I think the CCRadio-EP Pro is simply not suited for DXing.
Note: C. Crane engineering has informed me that future production runs of the CCRadio-EP Pro may have a 10/9 kHz switch, thus eliminating this negative. If you’re reading this review a few months after time of posting––crossed fingers––this may already be resolved.
FM Performance
If you’re looking for a simple AM/FM radio, and plan to spend most of your time on the FM band, you’ll like the CCRadio-EP Pro.
Positive: Audio
FM audio is very good on the CCRadio-EP Pro. I think it would be safe to say that it’s superior to most other receivers currently on the market in its $85 price range. Audio is room-filling and has good characteristics with dedicated adjustments for Bass and Treble. FM audio is reminiscent of 1970s-era solid-state receivers like the GE Superadio (a big positive, in my book). The bass is not very deep and resonant, nor the treble super-crisp, but the sound overall is very pleasant to the ear.
Positive: Sensitivity
The EP Pro is a sensitive FM receiver. It received all of my benchmark local and distant FM stations.
Positive: No drifting
As with AM, the EP Pro does not drift off frequency (again, this is actually a DSP radio).
The FM band is less affected by some of the negatives that impact AM broadcast band listening:
Negative: Inaccurate dial
As with the AM dial, FM frequency markings are slightly off. I measured the entire FM band and found that the upper half of the dial (above 102 MHz) seemed to deviate the most. See images below comparing the Tecsun PL-660 and CCRadio-EP Pro tuned to the same FM frequencies:
Here are a few examples of the CCRadio-EP Pro and Tecsun PL-660 tuned to the same frequencies:
Note: As mentioned above, C. Crane is trying to implement a fix for this in future production runs.
Negative: Imaging
As with the AM band, you will find imaging on the FM band. This bothers me less on the FM band, but I live in an area where the FM dial isn’t incredibly crowded. If you live in an urban market with stations packed into the dial, then the imaging concern will probably make the experience of listening to a weak station adjacent to a strong station quite unpleasant.
What about muting between frequencies? While you can hear frequency steps on the FM band, there is little to no muting between frequencies. It almost feels more like an analog radio.
Funny, but the weak signal images around a strong FM frequency actually help contribute to an analog-like experience during band scanning, as stations seem to rise and fall as you tune.
There is another factor that I don’t really consider a positive, but is worth noting. The EP Pro is one of the best mechanically-tuned DSP receivers to use on the FM band because the slide rule dial is wide––there’s a larger space for the needle to travel. FM band scanning would be a pretty pleasant experience if only the dial markings were more accurate.
Summary
Every radio has its pros and cons. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget some of my initial impressions. Here is the list I formed over the time I’ve spent evaluating the C. Crane CCRadio-EP Pro.
Pros:
Excellent AM sensitivity
Good audio via internal speaker
Internal Twin Coil Ferrite AM antenna provides excellent gain and nulling
My conclusion is that the first production run of the CCradio-EP Pro is simply not an enthusiasts’ radio.
If you read the list of negatives in the AM performance section of this review, you’ll know why I simply can’t recommend it…at least not yet. If C. Crane could minimize AM muting, improve imaging and fix the frequency accuracy, this radio may prove more promising. But at this point, the limited production run CCRadio-EP Pro lacks the level of refinement that I’ve come to expect from a C. Crane radio.
For what it’s worth, I have been in close contact with C. Crane regarding these issues; the company is taking them to heart and even looking to implement some fixes/adjustments prior to their full production run. As these issues are resolved, I’ll amend this review. Click here to read the second production run review.
The lack of refinements is somewhat disheartening. Otherwise, the CCR-EP Pro would be a great mediumwave DXing machine. When on frequency, it’s quite sensitive and stable! Perhaps some mediumwave DXers could overlook the negatives above to take advantage of this. I would not, however. I’d soon find the problems frustrating and turn to other receivers in my arsenal. Sensitivity is important, but personally I would sacrifice sensitivity to have an overall better tuning and listening experience.
On the other hand––as C.Crane makes a point of stating––the CC-Radio EP Pro was designed around the needs of Bob Crane’s mother: so is essentially an effective radio for casual listening that’s utterly simple to use. In this respect, at least, the EP Pro is a success.
The EP Pro has no multi-function buttons, no menus, and no memories. The knobs and buttons are tactile and obvious. The backlit dial is also a nice touch; I love it. The EP Pro is old school design around a modern DSP chip and, in terms of audio, a hat tip to classic solid state analog radios from the 1970s and 80s.
The casual listener––especially those who use radio to primarily listen to their one favorite station––will enjoy the EP Pro. For example, I have an older friend who’s in the process of replacing his bedside radio of 30+ years. He wants a set he can tune to his staple AM broadcast station (which is not a super-easy catch) and leave it on frequency––essentially, he wants a “set it and forget it” radio. I think the EP Pro will work well for this application.
But for radio enthusiasts––like most of you wonderful people who read the SWLing Post––I would pass on the EP Pro and consider a more capable mediumwave radio instead like the original CCRadio-EP, the CC-Radio 2E, or a vintage solid state set like the GE Superadio, Sony-5500W, or the venerable Panasonic RF-2200.
You can purchase the CCRadio-EP Pro from the following retailers:
I’m in the process of writing up a review of the C. Crane CCRadio-EP Pro, but a number of readers have been asking about how pronounced muting is between frequencies while band scanning.
To be clear, the CCRadio-EP Pro is not a true analog set like the original CCRadio-EP (even though it looks like an analog set). The EP Pro is based on the Silicon Labs SI4734 DSP chip, hence the frequency steps in 10 kHz increments and are not fluid/seamless as they would on analog sets.
Muting is more pronounced on the AM broadcast band than it is on the FM band. Here are two video demonstrations:
The audio “pop” that I note (when the CCRadio-EP Pro is first turned on) is bit annoying and can even be heard in nearby radios if they’re on. While doing my comparisons with the Sony ICF-5500W and the Tecsun PL-660, for example, the audio pop could be heard in both units as I turned on the EP Pro. I’m willing to bet this is only prevalent in the DSP chip version of the EP series.
