Remember the American television game show To Tell The Truth? This very long-running show challenged four celebrity guests and viewers to identify the real “central character” in the midst of two impostors.I was reminded of this game show when attempting to tell the difference between the original and recently updated versions of C. Crane’s CCRadio-EP Pro receiver when viewing the front panels. If there’s a difference, I can’t spot it! You need to turn around the radios to see the new EP-Pro’s key feature: switchable 9 kHz/10 kHz tuning steps.
The only clue to the newest version of the CCRadio-EP Pro is the 9/10 kHz tuning switch on the back panel.
I recently met with a good friend and radio hobbyist from Oregon to compare a few selected portable radios, FSL (Ferrite Sleeve Loop) antennas, and the newest low-noise Wellbrook ALA100LN module that was introduced just a few weeks ago. I was particularly interested in a head-to-head match-up of my friend’s original EP-Pro versus my newly arrived EP-Pro (9 kHz/10 kHz steps) version.
I’m looking forward to Thomas’ usual thorough review of the new CCRadio-EP Pro, but I want to offer a few observations of medium wave tuning after my time with the two models:
On very weak daytime MW signals, the radios are equally sensitive except on higher frequencies where the new model excels to a moderate degree. It’s enough of an advantage to make the difference between catching an ID or not on a low, DX-level signal.
The new EP-Pro feels more accurate–and simply more enjoyable–to tune, thanks to the elimination of false “peaks” surrounding the main signal. This is a BIG plus for the new radio, and frankly the CCRadio-EP should have performed this way from the start. Kudos to C. Crane for correcting this problem, but I can understand why the original version was brought to market with the odd tuning quirk. It isn’t a deal breaker for most non-DXing purchasers.
I could not find an instance of soft muting on either radio. I listened for a while to signals barely above the noise floor, and never did audio “cut in and out” suddenly, a clue to soft muting. Both receivers are very useful for chasing weak MW stations…but the new version is highly preferred for ease of tuning because of the lack of false audio peaks.
With the tuning working way it should, medium wave channels “snap” in and out as you slowly tune. This took a little getting used to, but after a while I began to appreciate the sense of exactness with the newest CCRadio-EP Pro.
Fast excursions up or down the band (either radio) will blank the audio, recovering when you stop tuning or slow down. I believe this is simply a case of exceeding the AGC’s recovery time, not soft muting. It’s easy to live with, but granted the effect is not one of smoothness as found on traditional, non-DSP analog receivers. Successful DXing takes a slower approach anyway when scanning the band; casual listeners may be more annoyed by either version of the radio if they are used to very quick knob-cranking.
The Twin Coil Ferrite “AM Fine Tuning” control works well on both units, and gives significant gain to weak signals on either extremity of the band. I love this feature; it makes digging out the weak ones a lot more fun!
So, should you buy the newest CCRadio-EP Pro with the 9 kHz/10 kHz steps?
If you already own a CCRadio-EP Pro and are fine with the false tuning peaks and have no desire for the 9 kHz MW step option–keep your radio! Only on high band does the new model have a sensitivity edge. Especially don’t make the jump if you’re a casual listener and listen only to a handful of local stations, or a single distant station.
If you do not own a CCRadio-EP Pro yet, but are in the market, definitely buy the newest version. Be aware that you can only be assured of getting the newest model if you purchase directly from C. Crane. Amazon does not yet carry the newest version according to some reports.
If you’re a radio junkie and just have to have both…go ahead…we understand!
I also made a short video comparison of the new EP Pro versus the top-ranked Panasonic RF-2200 on medium wave:

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:
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):
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):
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:
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:
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.

Wow! A mediumwave DX catch of 8,072 miles using a compact (heavily souped-up!) CC Skywave SSB? Simply amazing, Gary!
Your enthusiasm and passion for Ultralight DX is simply infectious!
