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.

Chasing Low-Power FM Stations

Male voice, singing: You’re the reason I have bald tires on my car . . .

Female voice, singing: You’re the reason I threw your clothes out in the yard . . .

Male and female voices singing in harmony: You’re the reason our kids are ugly . . .

. . . and that was my introduction to WOOG low-power community radio in Troy, NY.

Holy smokes . . . that’s outrageous . . . and funny, too!

Sometimes, in hindsight, it can be difficult for a writer to determine when and where story actually began.

With this one, was it when the FCC began licensing low-power community radio stations in 2000? Or was it when I began hosting a Radio Monitoring Net on the local 146.94 repeater (Troy, NY) at 7 pm on Tuesday nights?

For sure, a tipping point was when one of the net participants suggested check out a low-power FM community radio station on 92.7 FM. It’s kind of like western swing, he said.

I did check it out and found it to be a combo of traditional country and what I call “hillbilly jazz.” No announcer between musical selections, and occasional station IDs. At 7 am, I heard the Ralph Nader radio hour. Allegedly it is licensed to the Oakwood Community Center in Troy, NY, but nothing on the air that I have heard suggests that connection. Very curious. Is a place-holder for something else?

It turns out there are hundreds of low-power community radio stations across the United States. They are limited to 100 watts and an antenna height of 30 meters (100 feet). According to the FCC:

To qualify for an LPFM license, you must be:

A government or non-profit educational institution, like a public or private school or state or private university
A non-profit organization, association or entity with an educational purpose, like a community group, public service or public health organization, disability service provider or faith-based organization
A government or non-profit entity providing local public safety or transportation service, like a volunteer fire department, local government or state transportation authority
An Indian or Alaska Native tribe, band, nation, pueblo, village or community that will provide non-commercial radio services.

In addition, applicants for LPFM licenses must be based in the community in which they intend to broadcast. An organization is considered community-based if:

It is physically headquartered or has a campus within 10 miles of the proposed transmitting antenna
Seventy-five percent of its governing board resides within 10 miles of the proposed transmitting antenna
It is a non-profit or governmental public safety organization that intends to broadcast within the area of its jurisdiction
In the case of a Tribal application, the applicant’s Tribal lands are within the service area of the proposed station.

There is an article about LPFM stations here: https://www.pewresearch.org/short-reads/2016/09/19/number-of-u-s-low-power-fm-radio-stations-has-nearly-doubled-since-2014/ and a listing of the stations here: https://en.wikipedia.org/wiki/Category:Low-power_FM_radio_stations_in_the_United_States

There are several LPFM stations in my area, and chasing them is fun. I found the best success with my Tecsun PL-880 and its long whip antenna. Sometimes the whip works best when held vertically; sometimes, horizontally; sometimes moving the whip horizontally as little as 45 degrees will blank one station and bring up another. The end effect is to look like a drunken sword master while getting into the Better Half’s potted plants, knocking over scanners on the desk, and other encounters with the long whip.

Nevertheless, chasing low power community radio stations is fun, and I can predict, with some authority, that you may encounter programming that you won’t find anywhere else.

A little barefoot ultralight MW DXing . . . in which my mental status is questioned

33 Replies

By Jock Elliott, KB2GOM

About 10 days ago, the Better Half and I visited my wife’s sister in Sodus, NY, a small town in the western part of the state near the shores of Lake Ontario.

First consideration when packing was – never mind the underwear and the toothpaste – what radios shall I take? I decided to go light . . . just a CCrane Skywave SSB and a Uniden BC125AT analog-only scanner.

In the predawn hours on a handful of mornings, I decided to see what I could hear on medium wave with the diminutive Skywave SSB. The Skywave is an “ultralight” radio – under 20 cubic inches in volume. Because the Skywave’s plastic case is so small, the ferrite antenna within it is very small . . . less than 3 inches long. It is by no means a huge antenna for grabbing signals.

It was Gary DeBock who pioneered ultralight DXing with tiny generally inexpensive radios. As a ham radio operator, he had worked 144 countries using a Heathkit 1-2 watt kit transmitter he had built. In the process, he learned a great deal about propagation.

In 2007, he decided to see what he could do with a cheap pocket radio, a Sony Walkman SRS 59. At 1 am on an autumn night from his home in Washington state, he put propagation and operating skill to work and heard three distant medium-wave stations: a couple from Japan and one from Korea. He posted his results on the internet in November, 2007, and he got a lot skeptical feedback: How could you possibly do this?

His response (in essence): Try it for yourself.

Some people did try for themselves; some with great success. One DXer from Canada logged 300 stations in 30 days. Interest in MW DXing with pocket-sized consumer radios took off, and ultralight DXing was born.

So, in the predawn hours in Sodus, NY, I decided to give ultralight DXing a try . . . barefoot . . . that means with no external antennas or signal boosters . . . just me kicked back in a recliner, the CCrane Skywave SSB, and a pair of headphones. Simple.

Before we proceed, you need to understand that my DXing style might charitably be described as “lazy.” Instead of laboriously turning the tuning knob, I use the seek function on the CCrane Skywave. I simply press and hold for a moment the up or down arrow and wait for the Skywave to stop at the next signal it detects. Then, if I feel that the signal might be enhanced by re-orienting the antenna with respect to the signal, I wiggle the Skywave around in my hand and listen for an improvement in what I am hearing through the headphones.

The results: I logged (among others) Atlanta, Georgia (493 miles) and Charlotte, North Carolina (588 miles) on the CCrane Skywave SSB with its tiny internal antenna. Also received: Boston, Philadelphia, New York City, Baltimore, and Toronto and a bunch of unknowns.

One afternoon, I decided to see what distant stations Skywave might receive during the daylight hours. I was kicked back in the recliner with headphones on, doing my usual, waving the Skywave around in the air to optimize the reception. My sister-in-law started laughing. She said I looked like a demented band leader, conducting a silent orchestra! I tried to assure her that my mental status was OK and that I was trying to optimize the signal. I’m not sure it worked.

But one thing is certain: barefoot ultralight MW DXing is fun. All you need is a tiny radio, a bit of darkness, a pair of headphones, and a willingness to be surprised.

A Review of Two Medium Wave Signal Boosters

27 Replies

By Jock Elliott, KB2GOM

It was the survey that Thomas, our Maximum Leader, conducted that got me to thinking about this.

The survey revealed that portable radios were used 38.6% of the time by SWLing Post readers as their “daily driver.” I like portable radios, too, and use them frequently. Hold that thought for a moment.

I also like medium wave DXing (content DXing, really, I enjoy tuning around for unusual programs) because, as Gary DeBock once put it: “It’s a target-rich environment.” With that in mind, I was exploring the CCrane website and found a couple of items – the Terk AM Advantage and the Twin Coil Ferrite® AM Antenna Signal Booster that looked like they might help portable radio listeners who want to pull in medium-wave signals better. I asked the CCrane folks if they would like to review both products, and they sent them to me without charge.

Bottom line: they both work for boosting reception of medium-wave signals.

The Terk AM Advantage is a nine-inch tunable loop encased in plastic, and it requires no power supply. Simply place it near your portable receiver and just the dial to the desired frequency, and you could get up to a 20 dB gain in the signal you want to hear. The loop of the Terk AM Advantage inductively couples with the ferrite antenna inside your portable radio, although the unit comes with a direct wire connector that can be used with some radios.

I tried the Terk AM Advantage with my CCrane Skywave SSB on an AM that was coming in with a lot of static at my location. Without the AM Advantage, I had 3 bars of signal strength. As soon as I placed the AM Advantage close to the Skywave and adjusted the tuning knob, the signal strength increase to 5 bars, and the audio was much easier to hear with less noise.

With my Tecsun PL-880, which has a numerical signal strength meter, signal strength was 11 without the AM Advantage, but with the AM Advantage, signal strength increased to 14, and it was much easier to hear. The Terk AM Advantage definitely provides a modest boost in signal strength and clarity, is easy to use, and requires no batteries or external power supply.

The Twin Coil Ferrite® AM Antenna Signal Booster is more complicated. It consists of an antenna element that measures 8.5″ W x 2.5″ H x 1.25″D, a tuner unit that measures 3.25″ W x 4.25″ H x 1.25″ D, a small ferrite stick, and some patch cords. It comes with an AC adaptor and can also be powered by a 9-volt battery. For radios with external antenna connectors, package also includes a RCA female patch cord to two bare wire ends.

Set up is pretty easy: connect the tuner unit to the antenna element with a patch cord; connect the tune to the ferrite stick with another patch, and provide power through either the AC adaptor or 9-volt battery. (I used a battery).

Here are C.Crane’s directions for how to use The Twin Coil Ferrite® AM Antenna Signal Booster with a portable radio:

Place the Tuner Control in a comfortable location relative to your radio. Place the Antenna Element a few feet away. If the Antenna Element is placed too close to the radio, it will cause noise on your radio.
Place the Ferrite Stick on top of the radio near the center. Placement will vary depending on where the internal AM antenna of the radio is located.
For testing purposes, tune your radio to any weak AM station. It is important that the station be weak so you can clearly detect the improvement in reception.
Rotate the Fine Tune control, it will click on and the red LED indicator light will come on. Turn the Coarse Tune control knob slowly and you will likely notice a change in reception at some point on the dial. Adjust the control knob until you notice the most improvement on your signal. Now you can use the Fine Tune control for further refinement.
Move the Ferrite Stick around the radio to find the position that affects the signal the most. This position is the “sweet spot”, or the best position. Again, adjust the Fine Tune on the Tuner Control for the best reception possible. (I used rubber band to hold the Ferrite Stick in place, but the unit comes with some double-stick foam tape to hold it in place.)
Now you can orientate the Antenna Element for best reception. In most cases, the Antenna Element does not have to be adjusted again. When radio noise is a problem, try rotating the Antenna Element in the direction which reduces noise to a minimum.

And The Twin Coil Ferrite® AM Antenna Signal Booster works like crazy! With same station on my CCrane Skywave SSB, it boosted signal strength from 3 bars to full scale. With my Tecsun PL-880, it increased signal strength from 11 to 38.

In my view, although The Twin Coil Ferrite® AM Antenna Signal Booster costs twice as much as the Terk AM Advantage and is more complicated to use, it is more than twice as effective in boosting medium-wave signals.

In which C.Crane displays a high degree of “cool”

By Jock Elliott, KB2GOM

Okay, let’s get this straight to begin with: I’m not on C.Crane’s payroll; I get nothing for what you are about to read. I have bought two of their radios with my own money, and they sent me one for review.

Today I received an email from C.Crane, headlined “How to make a shortwave antenna.” It links to an online article, written by Bob Crane, with the same title. Here’s the link.

It explains, clearly and concisely, how to make your own shortwave antenna, and it also adds some safety warnings. Check it out; it’s worth reading and maybe home-brewing your own antenna.

What makes this a high degree of cool is that C.Crane also sells shortwave antennas . . . and yet they tell you how to make your own if you so choose. Nice.

Frankly, I’ve been a fan of the C.Crane company for years. Now I am a bigger one.

Follow-up to The Great Medium Wave Daylight DX Challenge

If the folks who participated in The Great Medium Wave Daylight DX Challenge were on trial for “having fun,” they would be found guilty and sentenced to . . . more DXing challenges!

Results

As nearly as I can tell, 13 people participated, and many had something positive to say about the experience, including they would like to do it again.

I say “as nearly as I can tell” with regard to the number of participants because some people posted the same thing multiple times . . . and there is a simple reason why. When someone posts a comment for the first time, or posts a comment for the first time with a new email address (which is one of the required fields when you post a comment), that comment is sent to moderation for approval before it is posted . . . which causes a delay. Thinking it didn’t work the first time, the commenter reposts again (and perhaps again and again) and after a while, all the posts appear, which confuses the counting process.

A variety of equipment was used: 4 GE Superadios, 2 Belka radios, a Yaesu FT950, an AirSpy SDR, a single-transistor regenerative radio, and a Sangean ATS 909-X2. Some ran barefoot (using internal antennas), some employed loops, dipoles, and even an AFA-200 from Icom.

In terms of station count, Tom Laskowski, in a neighborhood park in South Bend, Indiana, absolutely killed it with a GE Superadio, logging 69 stations with lots of colorful detail. Clearly he was enjoying himself. The total mileage of his top five stations was 1230 miles. He qualified for Chuck Rippel’s generous offer of a Superadio refurb.

13dka “informally reported” his results in miles, furlongs, and attoparsecs. From a dike at the German North Sea Coast (Riddle of the Sands?), his farthest station was 677 miles away and his top five total was 2748 miles . . . that’s 21,968.5 furlongs in case you were wondering. He used a Belka 2022 in combination with an AFA-200 active ferrite antenna (his ultra portable MW rig).

David Mappin in Filey, UK, managed to hear a station in Solt, Hungary, at a distance of 987 miles. His top five total mileage was 1965 miles. He used a Sangean ATS 909X2 with a Cross Country Wireless (CCW) Loop Antenna Amplifier with a one-meter loop made out of coax.

Everyone seemed to have a good time, even those to whom “life happened,” and could only get on for a few minutes.

So, therefore, you are all sentenced to more DX challenges in the future!

My operatives (the upstate irregulars) deep in the underground bunker at El Rancho Elliott tell me that some of the names of future challenges might include “The Midnight Ramble” and “The Grayline Sprint” . . . but these sources are unreliable.

In the meantime, thanks to all for participating, and I am glad you had fun.

PS – Some have suggested that taking station transmit power into account when figuring out scoring might be a thing to do. If you have practical ideas for doing this, post them, with examples in the comments section below. Bear in mind that any calculation of “difficulty factor” will fall on the folks recording their logs.
