Many thanks to SWLing Post contributor, Don Moore–author of  Following Ghosts in Northern Peru–for the following guest post:

One of my favorite DXing locations was this little cottage at the El Rancho Hotel just outside San Ramon, on the edge of the Amazon jungle in Peru. At $18/night, including breakfast, the hotel was a bargain, and there was plenty of room for my delta loop.

A Guide To Vagabond DXing

By Don Moore

Ever since I served as a Peace Corps volunteer in Honduras in the early 1980s, Latin America has been my primary focus for both DXing and traveling. So when I retired in 2017, my main goal was to begin taking long annual trips . . . and I do mean long. From October 2017 to May 2018, I traveled through Peru, Ecuador, and Colombia visiting about fifty different towns and cities. This year, I’m on a five-month trip through southern South America. In Latin America you can get just about anywhere cheaply and easily by bus, so that’s how I get around. It’s also a great way to meet people and to see the countryside. But luggage can become a burden, so I limit myself to a single mid-sized wheeled suitcase and a large knapsack. And that means that my mobile DX shack has to be very carefully planned.

Your plans may not include multi-month odysseys like mine, but I think my experiences will help you prepare to DX on your next trip, wherever it might be. Of course, what makes a good mobile DX shack depends on what your DX interests are. I consider myself a station collector, in that I want to make loggings of lots of new and different stations and to build up an understanding of radio broadcasting in different regions. So on my travels I concentrate on the medium wave broadcast band and longwave beacons, with maybe little bit of shortwave utility DX. (There’s not much on shortwave broadcast that I can’t also hear at home.)

Take the DX Home With You

For years my standard DX travel gear was a Sony ICF-2010, a cassette recorder, and an old Radio West ferrite loop antenna. But listening time was always limited since it was a vacation. There were other activities on the agenda and I was generally too tired to get up early for DXing. I always went home with some interesting loggings and audio recordings, but once I left for home the DXing was done.

SDRs have changed all that and now my first rule of travel DX now is take the DX home. The best souvenir of a trip is the hundreds of hours of DXing that I take home with me. In a 2016 trip to central Colombia, I made about 300 MB of recordings of the medium wave band. While listening to them later I logged over 400 stations from twenty countries (and I still have about half the files to go through). I never would have even gotten close to that many stations listening on my Sony like an ‘old-fashioned’ DXer, hi!

Lately, I’ve been accumulating SDR files much faster than I could possibly go through them, so it’s a fair question to ask what the point is. When will I ever listen to them all? Like most DXers, I’m not fortunate enough to live in a perfect DX location. When conditions are mediocre, I’d rather spend my DXing time going through some more interesting SDR files.  And, I know I’ll have lots of good DX waiting for me years from now when I’m no longer able to travel the way that I do now. For me, SDR recordings make much better souvenirs that some cheap tourist trinkets that will gather dust on a shelf. It doesn’t matter whether your travels take you to a nearby park or to a distant continent. SDRs can preserve the DXing experience for years to come.

My Mobile DX Shack

This is my typical DXing setup with the Afedri. The rooftoop terrace at the Hotel Rosa Ermila ($10/night) in Cascas, Peru was the most elegant place I’ve ever DXed from, but reception was only average with the PA0RDT dangling from the railing.

The centerpiece of any DX shack is the receiver. On my 2017-18 trip, I had an Afredri SDR-Net with an SDRPlay RSP1 as a backup, but this year I replaced the Afedri with an Elad FDM-2. Together, my two SDRs are smaller than all but the smallest portable receivers. Of course I also need a laptop, but I’m going to take one anyway. An important consideration in selecting a travel SDR is to get something that is powered off the laptop’s USB connection so that it is easy to DX totally off battery power if line noise becomes an issue.

The other vital component of DXing is the antenna. A good on-the-road antenna for SDR DXing has to be small, easy to erect, broadband, and versatile. That sounds like a lot to ask, but the perfect DX travel antennas do exist.

For compactness and ease of use, nothing can surpass the PA0RDT mini-whip. How good is it? That’s what I used to log over 400 medium wave stations in Colombia in 2016. I just attached the unit to my coax and threw it about three meters up into a short tree. The antenna works best when mounted away from nearby structures, but sometimes I’ve gotten decent results placing the PA0RDT on balconies and windowsills of tall buildings. It’s mostly a matter of luck as to how bad the local noise levels in the building are and how much the building itself may block signals. Using a short support, such as a broom or a hiking pole, it may be possible to mount the unit a meter or so away from the building.

While it’s best to mount the PA0RDT away from obstructions, the antenna might give good results anywhere, even on the neighbor’s roof. (Just make sure it’s not likely to get stuck. Pulling the unit out of a stubborn papaya tree is no joke.)

The biggest drawback of the PA0RDT for serious MW and LW DXing is that it is non-directional. For a directional antenna, a Wellbrook loop is great if you’re traveling by car, but that one-meter diameter aluminum loop doesn’t fit in my suitcase. Fortunately, a few years ago Guy Atkins and Brett Saylor told me about an alternative: buy a Wellbrook ALA-100LN unit and attach it to a large homemade wire loop. Now my travel kit includes two nine-meter lengths and one eighteen-meter length of #18 stranded copper wire. The wires can be spliced together for loops of 9, 18, 27, or 36 meters circumference, according to what fits in a location. Erection of a wire loop is easy enough with a suitable tree branch. I just throw the wire over the branch and then form it into delta (with the bottom running just above the ground) using two tent stakes and some short cord to hold the corners. The ALA-100LN unit goes in the bottom center.

Items that go in my suitcase, left to right: tent stakes and wire for the Wellbrook loop, a small box with more adapters, another battery box, 50 foot coax, 12 foot coax, and my hiking pole. The pole doubles as a support for the PA0RDT sometimes.

The loop doesn’t have to be in a delta; that’s just often the easiest to erect. I’ve successfully used squares, rectangles, trapezoids, oblong diamonds, and right angle triangles. Any balanced shape with the ALA-100LN in the bottom center should be bi-directional in a figure-eight pattern. Non-balanced shapes will work equally well but with unpredictable directionality. Just keep the wire in a single plane and place the ALA-100LN unit someplace along the bottom.

Both the PA0RDT and the Wellbrook require a 12V power supply. The North American version of the Wellbrook comes with an excellent noise-free 110V power supply, but that’s of no use in 220V countries and also I want to be able to DX totally off battery power when necessary. Fortunately both antennas use the same size power connector, so I carry three eight-cell AA battery packs for remote power.

Contents of the DX box, clockwise from upper left: the two pieces of the Wellbrook ALA-100LN, the two pieces of the PA0RDT mini-whip, two 8xAA battery boxes and a set of batteries, USB and coax cables, a passive 4-way antenna splitter, battery tester, various adapters and cup hooks (for securing wires), 4TB hard drive, the SDRPlay RSP1, the Elad FDM-2, and more short patch cords.

My mobile DX shack is rounded out with everything that is needed to connect the parts together. I have at least four of every adapter and patchcord, since I know they won’t be easy to replace on the road. For lead-ins, I have 12-foot and 50-foot lengths of lightweight coax with BNC connectors. I also have a few F-to-BNC adapters so I could buy some standard TV coax if needed. A 4 TB hard drive provides plenty of space the SDR recordings I plan to make. (Before leaving, I fill it with videos that I can delete after I watch them or when I need space.) For DX references, I download various station lists online so that I have them available even if I don’t have an Internet connection. It’s also important to keep those lists with the SDR files from the trip so that if I’m listening to the files years from now I’ll have references which were current at the time.

Airport Security

A common concern for traveling DXers is getting through airport security. When I went to Colombia in 2016, I wrapped my DX gear in clothing for protection and then stuffed everything into my backpack. Security didn’t like what they saw and I had to empty the bag so that every single item could be examined and swabbed for explosive residue. The TSA lady was very nice about it, but I wanted to minimize the chance of that happening again.

At an office supply store I found a plastic storage box that fits inside the main pocket of my backpack. My SDRs, antenna components, and hard drive get wrapped in bubble wrap and all placed together in the box along with small cables, adapters, etc. Larger items – the wire, coax, and stakes for the loop – get packed in my checked bag.

The DX Box packed and ready to go.

At the airport, I slide the box out of my backpack, place it into a cloth shopping bag, and then send it through the X-Ray machine on its own so that the agent can get a close look at the contents. So far in about a dozen security checks in the USA, Peru, and Mexico, the box of gear hasn’t caused so much as a pause on the conveyor belt. And, if the box would get pulled for a closer look, at least I won’t have to empty the entire backpack again.

Most of my equipment fits in this plastic box which slides into my backpack.

Where to DX

A mobile DX shack isn’t worth anything without a suitable place to DX from. Hotels may work if you have a balcony where you can put a small antenna, but more likely than not there’ll be problems with RF noise. The best hotels are ones that are a collection of cottages or bungalows or that otherwise have an open yard-like space for an antenna. My favorite place to find possible DXing sites is on AirBnB. It’s often easy to find AirBnBs that are on the edge of town or even in the countryside with lots of space. Of course, since I don’t have a car, I need to make sure I can get there using public transportation.

While visiting Huanchaco, Peru with DX friends Karl Forth and John Fisher, we had a beach-front apartment with an adjoining rooftop terrace. We had excellent results with an oblong loop and the ALA-100LN on the terrace.

The key to selecting a DX location is to examine all the photos very carefully. Is there open space for the antennas? Are there trees or other potential supports? Is there a gazebo, terrace, or other space that could be used for DXing? Google satellite view and Google street view can be very helpful in scouting out a location (And it’s surprising how much of South America is now on Google Street View.)  And, I always look for possible noise sources. One place I almost rented in Colombia turned out to have high voltage power lines running next door when I found it on Street View.

I always tell the hotel staff or AirBnB host what I’m doing so that they understand why the gringo has wires running around. And I make sure not to put my antennas or coax anywhere that might interfere with the employees or other guests. Most of the time I’m able to erect the antenna near my room and run the lead-in into my room through a window. Then I can leave my laptop running all night to make scheduled SDR recordings. That’s the Holy Grail of DXing – catching the overnight DX while you sleep. But if my room turns out to have too much RF noise (as has been the case a few times), then I head out to the gazebo or terrace to DX using battery power.  That does mean I have to stay up late or get up early since I can’t leave the laptop outside on its own. But, some of the best DX that I’ve had has come from running off full battery power in gazebos.

My delta loop had plenty of space at the Posada de Sauce ($25/night with breakfast) in the jungle near Tarapoto, Peru. The lodge was totally powered by solar panels and was one of the quietest places I’ve ever DXed from.

Antenna security is another consideration. At one place I stayed I wasn’t comfortable leaving my expensive antenna components unattended outside all night. And then there was what happened on my first trip to Colombia in 2010. I knew that a place I would be staying at for two nights had an open field right behind it, so on that trip I took 500 feet of thin insulated wire for a mini beverage-on-the-ground. DXing was great the first night but terrible the second. When I went out the next morning to wind up the wire I learned why. The worker who had been weed-wacking the hotel gardens the previous day had also done the field, and in doing so he had cut my wire in three places. He had, however, very nicely tied the wires back together.

Share the DX

DXing off battery power in the gazebo in the Mauro Hilton Hostel in the mountains above Manizales, Colombia. The antenna was the PA0RDT thrown in a tree. I had great DX with the loop from my room, but I came here to enjoy the views one evening.

Finally, if you take an SDR on a trip and get some good DX, make a selection of your files available for download. Other DXers will enjoy hearing what the band sounds like somewhere else. Several dozen of my files from Peru, Ecuador, and Colombia are available for download in a shared Google Drive folder. If you see something you want, be sure to download it now. The winter DX season is just starting here in deep South America and in the coming weeks I’ll be replacing some of those older files with ones made in Argentina and maybe in Uruguay and southern Brazil. I’ve found a lot of places to stay that look to be perfect for a vagabond DXer.

For fun, here are some of the better places I DXed from in Peru, Ecuador, and Colombia. The key thing to look for is an open place for the antennas:

Don, thank you so much for sharing your travel DXing expertise. This article is absolutely brilliant and so informative for anyone who wishes to make SDR field recordings. I love how carefully you’ve curated and distilled your portable setup and have given priority to having antennas for all occasions. I also think carrying spare parts and, especially, a spare SDR makes a lot of sense.

TC notes differences between Kenwood TH-D74 and TH-F6A on MW/SW

1 Reply

Many thanks to SWLing Post contributor, TC, who shares the following response to Ivan’s post about the Kenwood TH-D74 on mediumwave:

A couple of years ago, I published a side-by-side comparison of the TH-F6A and the TH-D74 on YouTube comparing reception of a local AM broadcast station. The F6A was far more sensitive on the AM broadcast band than the TH-D74.

You can see the video here:

Click here to view on YouTube.

I didn’t take the internal orientation of the bars into account, but the D74 is less sensitive in pretty much any orientation compared to the older F6A.

I contacted Kenwood about the difference, and they stated something to the effect of while the TH-D74 does receive MW, it wasn’t necessarily designed for it, and thus the reception there suffers compared to the F6A.

However, the tradeoff here seems to be better shortwave reception in the TH-D74 compared to the F6A. Hook the D74 up to a large wire antenna and you can easily pull in stuff on the shortwave broadcast and ham bands, and the IF filters help quite a bit as well.

Thanks for sharing, TC! I own a few wideband handheld transceivers so I keep a short SMA “pigtail” in my EDC pack that I can use to enhance HF performance. I simply clip a 15′ wire onto the pigtail’s  exposed conductor to enhance HF performance. Also, as Ivan points out, inductively pairing any of these tiny radios with a mag loop antenna will also augment performance on mediumwave.

Thanks again for sharing!

Guest Post: Repairing the National Panasonic DR22, the Panasonic RF-2200’s Euro-Sibling

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN), who shares the following guest post:

National Panasonic DR22, the Panasonic RF-2200’s Euro-Sibling

By Mario Filippi, N2HUN

(All photos courtesy of author)

Thomas, your recent and thoroughly excellent post on the Panasonic RF-2200 was the inspiration for this short review of the RF-2200’s European sibling, the National Panasonic DR22.

A few years back when I was hunting for a used RF-2200, a second-hand National Panasonic DR22 was for auction on eBay. These radios were sold in Europe and are almost an exact match for the RF-2200, with a few minor cosmetic differences.  It was so close in appearance that I decided to bid and won the auction. The cost was around $150.00 plus shipping.

Author’s National Panasonic DR22, a.k.a. RF-2200BS

The seller described the unit as working, not a tech special, and was complete except for the original earphone.  The strap, which can be missing on some used models was in place, the antenna and all the knobs were there. When the radio was received, all appeared to be working well and most importantly the rotatable ferrite antenna was fully functional.  With the exception of tiny paint specks and years of accumulated dust the unit was cosmetically acceptable for a 40 plus year old radio. After a close olfactory inspection (smelling the unit hi hi) it was determined the radio was from a smoke-free home, which is important as smoke not only causes yellowing of plastic components, but it inundates the internal electronic components and coats them with a yellowish-brown stain.

National Panasonic DR22 Dashboard Shows Slight Labeling Differences

On close inspection, the unit differs slightly from the RF-2200, in that it is branded as a “National  Panasonic” along with the “DR22” designation on the upper right of the unit. And, the National Panasonic logo can be seen to the left of the AM/SW gain control.  Another difference is the additional labeling found above each shortwave band, the designations are KW1, KW2, etc.

Power, Dial Light, and BFO Switches Are Identical to RF2200

As for the rear panel of the DR22, a major difference is the presence of a voltage selector which allows one to switch from European voltage (220) to the US standard (110).   Inside the unit there’s a transformer that handles this option. Alternatively you can simply use four “D” batteries to power the unit.

DR22 Line Voltage Selector Switch

After receiving the unit, first order of business was a good cleaning of the outer case with mild soap and water.  All the knobs and carrying strap were removed and soaked in a warm soapy solution. A toothbrush was put to work to remove years of human tactile residue from the sides of the knobs.

Knobs (left) removed for cleaning. Carrying strap (right) was inundated with decades of dirt.

Next on the “to do” list was to obtain a copy of the service manual, available on line.  You’ll find it under the title of National Panasonic RF-2200BA. It’s an excellent manual with detailed photos of the circuit boards, exploded diagrams of the mechanical parts, parts list, schematics, and of course the alignment procedure.   Cracking open the case required removal of all the case screws and very gently coaxing of the two panels apart. Years of use, rust on the screws, and dirt/dust buildup all contribute to the challenge of this endeavor.

DR22 Case Disassembly

The alignment took several weeks as the radio was worked on in my spare time.  Note that I did not replace any electrolytic capacitors, and yes it was the lazy man’s way but a basic inspection of the caps for any evident leaks, explosions, or burns was conducted.  In short I did not want to replace capacitors at this time since the radio, as received from the former owner, was working well on all bands. Surely, as other operators have reported, cap replacement will restore full operational excellence but I felt if the radio passes the alignment specifications  that was good enough for me at this point.

DR22 Undergoing Testing

After several weeks the radio was restored to specifications, all switches were cleaned and dusted and the radio reassembled.  This was done a few years ago and the radio continues performing well. Even the 125/500 KHz crystal markers are pretty much on the money when checked against WWV.  No scratchy pots either hi hi. So now the radio sits in my kitchen and is on at least a few hours a day and keeps company with its sister, my RF2200. Note that recently DR22s have sold on eBay for $150 – $300US. Tech specials/parts radio run considerably less.  Thanks and 73’s de N2HUN.

Thank you, Mario! It looks like you scored an excellent deal on the DR22 and it’s serving you quite well! I’m glad you spent time checking for leaky capacitors after opening the chassis. Using the DR22 so frequently will keep those caps “juicy!”

Post Readers: Please comment if you love the National Panasonic DR22!

Stan compares the C. Crane CCRadio3 with the CCRadio2E

5 Replies

Many thanks to SWLing Post contributor, Stan Horzepa (WA1LOU), who shares the following post originally published on his blog:

I bought a first-production-run C.Crane CCRadio3 AM/FM/WX/2-Meter receiver after reading K4SWL’s preview on his blog, The SWLing Post.

I already own the highly-regarded C.Crane CCRadio 2E Enhanced, which I reviewed here five years ago, so I decided to compare the two on the AM, FM and weather bands. Before comparing the two radios, I recalibrated the antennas of both radios, then with the radios sitting side-by-side, I tuned each radio through each band channel-by-channel

My findings follow.

On the AM band, the 3 captured signals faster than the 2E.

Occasionally, signals were stronger on the 3 than on the 2E and vice versa, but most of the time, the signal strength was the same on both radios. So I conclude that the sensitivity of the two radios are the same.

I tried the 3’s new Bluetooth function before reading the manual. I just pressed the Bluetooth button to access the Bluetooth mode and my iPhone and MacBook Pro found the 3 without pressing the radio’s Pair button, as instructed by the manual.

In conclusion, the differences I found between the 3 and the 2E were (1) the 3’s ability to capture AM signals was noticeably faster than the 2E and (2) the addition of the Bluetooth function in the 3.

I did not notice any other performance enhancements. I was hoping that the 3 might be more sensitive than the 2E (not that the 2E is not sensitive — it certainly is!), but I’d say that the 3 and 2E Enhanced are about equal sensitivity-wise, as well as selectivity-wise.

Believe it or not moments… During the comparison, I was very surprised that on two occasions (on 820 and 1500 kHz), each radio simultaneously received different stations while tuned to the same frequency!

Click here to check out Stan’s blog.

Thank you for sharing your thoughts after comparing the two receivers, Stan! I think this supports the idea that if one owns the CCRadio2E and doesn’t need Bluetooth functionality, there’s no real reason to upgrade to the CCRadio3. With that said, and as I think you found Stan, the Bluetooth functionality in the CCRadio3 is excellent. It must be one of the best Bluetooth receivers I’ve tested and as you point out, it’s also very easy to engage and use.

Thanks again!

Preview: The C. Crane CCRadio3 AM/FM/WX and 2 Meter receiver

20 Replies

In early January 2019, C. Crane sent me a pre-production unit of their latest radio for evaluation: the C. Crane CCRadio3.

Since I received the CCradio3, I’ve had it on the air and have been evaluating it in real-life listening conditions, searching for any potential quirks that C. Crane should address before a full production run of the radio hits the market.

Yesterday, C. Crane announced the CCRadio3 in their email newsletter:

So now, finally, I can break my silence to inform you all about this latest iteration of the venerable CCRadio. And, indeed, I have a lot to tell…

CCRadio3 Preview

What follows is a preview of the CCRadio3 based on my time with the pre-production unit. I will not refer to this as a “review” of the CCRadio3, since this is a pre-production unit.  I’ll obtain a first production run unit when available and post a full review at that time.

In the meantime…here are some of my impressions based on the pre-production unit, organized by feature.

Bluetooth

What’s new with the CCRadio3? The major upgrade is the addition of Bluetooth connectivity. In fact, that’s the only obvious upgrade other than the fact you can now toggle between AM/FM band rather than scroll through all the bands on one band button.

With Bluetooth connectivity, you can pair with your smart phone, tablet, laptop, PC or any other Bluetooth device, and use the CCRadio3 as your Bluetooth speaker.

How many radios do you know that include simple operation instructions on the chassis? Very simple.

The pairing is incredibly simple and Bluetooth connectivity most impressive. I find that no matter where I go in my house, the CCRadio3 maintains a solid Bluetooth connection with my iPhone. Most of my other Bluetooth devices will lose connectivity if I put a couple walls between my iPhone and the receiver, but not the CCRadio3.

Audio

The internal speaker on the CCRadio3 provides room-filling audio with clear, rich fidelity. The separate bass and treble controls do help tailor the sound based on the audio source. It reproduces music brilliantly in FM and Bluetooth modes.

2 Meter Ham Radio Band

One unique feature of the CCRadio series is 2 meter ham band reception. This is a great way to monitor local amateur radio repeater traffic.

In truth, I’ve spent comparatively little time with the CCRadio3 on 2 meters thus far, having focused instead on the AM/FM and WX bands, but I have verified that I can receive local repeaters and the squelch functionality is quite effective.

I’ll spend more time on this band in my upcoming full review.

Weather Radio (WX) Band

The CCRadio3 can receive all seven NOAA/Environment Canada radio frequencies.

And here’s something that really surprised me: this pre-production CCRadio3 has the best weather radio reception of any radio I’ve ever tested to date. Normally, at my home, I can receive two NOAA stations with the average weather radio. The best of my weather radio receivers might hear a total of three. The CCRadio3, with antenna fully-extended, can receive five NOAA stations! I can almost WX DX with this rig!

I’m so pleased C. Crane places an emphasis on WX band performance. Their CC Skywave and CC Skywave SSB also have best-in-class weather radio reception.

Like the CCRadio2E, the grab handle is built into the back of the radio.

The CCRadio3 uses four D cells for battery operation which should yield about 120 hours of AM broadcast listening at moderate volume.

FM

Thus far I’m very pleased with FM performance. I’ve noted that the CCRadio3 receives all of my local and distant benchmark stations with ease. I believe it would certainly be an FM benchmark receiver. As I mentioned earlier, audio fidelity is excellent via the internal speaker.

AM/Mediumwave

I consider the CCradio3’s predecessor––the CCRadio2E––to be one of the finest AM broadcasting listening portables currently in production. I’ll admit that when I heard the CCRadio3 added Bluetooth, I feared somehow that would equate to possible noise somewhere in the audio chain…Fortunately, this fear was entirely unfounded. In fact, looking at the CCRadio3 announcement, I note that C. Crane took this concern seriously:

“The CCRadio 3 is one of the few high-performance radios with Bluetooth® that has no detectable noise and some of the best reception available.”

When I first turned on the CCRadio3 and tuned to the AM band, I did what I always do when testing mediumwave performance: In the early morning, as the sun was rising (i.e., grey line propagation), I tried to pull my benchmark station––WAIZ, a 1,000 watt station about 95 miles away as the crow flies––out of the muddle. The CCRadio3 was able to do it; in fact, I could hear the station’s morning crew doing their “Wacky Wake-Up” shenanigans. Turning the radio body, I also gathered, rather quickly, that the CCRadio3’s Twin Coil Ferrite Bar antenna does an excellent job of nulling out unwanted stations.

An impressive start of the evaluation.

Comparing the CCRadio3 with Panny RF-2200

Looking around SWLing Post HQ, I picked up my recently re-capped and refurbished Panasonic RF-2200. I wanted to see how the CCRadio3 would stack up against what I consider one the finest AM broadcast portables ever produced…

I’ve tested the CCRadio3 and ‘2200 at various locations––in the morning, midday, and at night––and can say that not only does the CCRadio3 give the RF-2200 a run for its money, but it even outperforms the RF-2200 at times, in terms of weak station intelligibility.

In fact, I think the CCRadio3 may possibly have a very slight edge on the RF-2200 in terms of sensitivity, as well.

However, note that there are two factors that make this comparison a tough call:

  • First of all, I find that the RF-2200’s AGC is smoother than that of the CCRadio3––the peaks and dips in audio are not as strong when listening through AM flutter. Most of the time, this makes it a little easier for me to discern weak signal audio. I believe the CCRadio3’s AGC and soft mute may be making the troughs in AGC a little deeper, as well. It would be amazing if C. Crane could allow users to disable soft mute like recent Sangean models have.
  • Secondly, the RF-2200 has two AM bandwidth settings: narrow and wide. I almost always use the RF-2200 with the wide bandwidth setting. I find the narrow filter is a little too narrow unless I need it to block an adjacent signal.  In general, I use wider AM filter settings than many DXers because I find that the filter between my ears does a better job of discerning signals with a little more audio information.

The CCRadio3 has only one bandwidth. I’m guessing––based purely on my listening experience––that it’s 4 to 6 kHz in width.  (I’ll try to confirm this with C. Crane).   Obviously this is narrower than the RF-2200’s wide filter. In side-by-side comparisons, the RF-2200’s AM fidelity therefore sounds much richer, especially when music is involved.

That this is so really shouldn’t be a surprise, as the Radio3 and its predecessors were designed around spoken word intelligibility––in other words, making it easy for the listener to understand what’s being said. And, frankly, it works. Most of the time, I find that the CCRadio3 does a better job of making weak signals “pop” out of the static. It’s a little easier catching weak signal station IDs with the CCRadio3, even if you have to listen through a more active AGC/soft mute tug.

So…is the CCRadio3 (at least, this pre-production unit) better than the RF-2200 at weak signal DXing? In some respects, yes. In others, not quite. Yet the fact that it can even compare with the RF-2200 speaks volumes…no pun intended. I would have never guessed that it would have a sensitivity edge on the RF-2200.

Of course, the CCRadio3 has both AM antenna and ground terminals.

I made a few early afternoon videos comparing the CCRadio3 with the RF-2200. In the first video, I’m tuned to a station approximately 20-25 miles away. You’ll note how the RF-2200’s audio fidelity, with the wide filter engaged, is hard to match:

In the second video, I’m tuned to 1290 AM (WHKY), a 50,000 watt station about 95 miles away. [Note that I erroneously give an inaccurate mileage figure in this video; not sure what I was thinking!  Sorry about that, folks.]

In the third video, I’m tuned to 630 AM (WAIZ), again, a 1000 watt station about 100 miles away. As you can imagine, it’s very weak and both radios struggle to receive any intelligible audio through the ocean waves of fluttering radio jumble. [Again, please ignore the distance I give in the video; this station is actually a little over 95 miles away.]

I also did a late afternoon comparison video around sunset using one of my favorite AM radio stations ever: CFZM in Toronto–about 980 miles distant. Here’s the video:

In these video comparisons, the radios are nearly side-by-side.  I found this had little to no effect on reception. When comparing these radios off camera, I had them spaced at least 40″ apart and always, of course, oriented the antennas identically.

Conclusion

Again, this is merely a preview of the pre-production unit of the CCRadio3. I thought I’d touch on reception and a few of the key points that might help some of the CCRadio3’s early adopters make a purchase decision. I have yet to do testing with headphones or external antennas and still wish to compare it with even more radios, to make my review as thorough as I’d like.

And I’m really looking forward to reviewing the production unit of the CCRadio3, because this pre-production receiver has certainly surpassed my expectations!

This latest iteration of the CCRadio should remain king of AM radio reception, compared with any other portable radio currently in production.

C. Crane has announced that they have a very limited number of first-production-run units available for order right now.  If you order one, use the coupon code CC3B19 at checkout, so that, as the above ad suggests, you can snag it for $179.00–$20 off the future retail price. I suspect this first run will sell out fast.

Radios: What are your daily drivers?

43 Replies

Many thanks to SWLing Post contributor, John C., who writes:

“Hi Thomas, I love [the SWLing Post] and have been meaning to thank you for all of the amazing reviews. Truly a treasure trove. But as I contemplate my next radio purchase I would like to know what radio you use more than any other. In other words…what’s your daily driver??? Enquiring minds want to know! Thank you. – JC”

Thanks for your question and the kind compliment, John.

Your inquiry is one I get quite a bit, so I hope you don’t mind if I share my response here publicly.

First of all, I should state that I don’t have a single “daily driver.”

Since I evaluate, test, and review radios I spend a lot of time with a variety of new receivers and transceivers.

I’m currently evaluating the Radiwow R-108, so it goes with me pretty much everywhere since I like to test receivers in a variety of settings. I’m also packing the Tecsun PL-310ET and the CC Skywave so I have units to compare with the R-108.

My Daily Drivers

Still, there are a number of radios in my life that get heavy use. Here’s my current list based on activity:

For Travel

When I travel, I reach for my favorite multi-function ultra-compact shortwave portable. In the past, I would have reached for the Grundig G6, the Sony ICF-SW100, the Tecsun PL-310ET, the Digitech AR-1780, or the C. Crane CC Skywave, Currently, I reach for the C. Crane CC Skywave SSB.

When I travel, I try to pack as lightly as I can–perhaps some would even call me a borderline travel minimalist. For example, when I fly to Philadelphia later this month for the Winter SWL Fest, I will take only one piece of luggage, a “personal carry-on” item: the Tom Bihn Stowaway, a pack the size of a small laptop bag. The Stowaway will contain my iPad, cords/accessories, and all of my clothes and toiletries for about 5 days of travel. As you can imagine, there’s not a lot of spare room in there for radio gear (quite the understatement).

I’ll still have room in my bag for the CC Skywave SSB, though, because the receiver is so compact. In addition, it’s a little “Swiss Army Knife” of a radio which covers the AM/MW, Shortwave, WX, and AIR bands.  It also has SSB mode and uses common AA batteries. The Skywave SSB is a welcome travel companion.

For Portable Shortwave DX

When I head to a park or go on a camping trip with the goal of doing a little weak signal DXing, I reach for a full-featured portable. In the past, I’ve relied heavily on the Tecsun PL-660 or PL-680, the Sony ICF-SW7600GR, and the Tecsun PL-880.

After acquiring the amazing Panasonic RF-B65 last year, it has become my choice full-featured portable. Of course, the RF-65B hasn’t been in production for ages, but thanks to a number of friends/enablers (including Dan Robinson and Troy Riedel) I finally found one for an acceptable price on eBay.

I’ve been incredibly pleased with the RF-B65’s performance and feel like I got a decent deal snagging one in great shape for less than $200. Only a few months prior to my purchase, it was hard to find good units under $300. Click here to check current prices, if interested.

For Morning News and Music

Since my staple morning news source, Radio Australia, went off the air, I spend a lot more time in the mornings listening to Internet radio mainly because I like listening to news sources that no longer, or never have, broadcast on the shortwaves.

Without a doubt, my favorite WiFi radio is the Como Audio Solo. I use it to listen to the CBC in St. John’s Newfoundland, The UK 1940s Radio Station, RFI Musique, ABC Radio Sydney, and a number of other news and music outlets.

The Como Audio Solo also serves as an audio feed for my SSTran AM Transmitter which then allows me to listen to all of this excellent content on 1570 kHz with vintage tube radios such as my Scott Marine SLR-M, my BC-348-Q, and my Minerva Tropicmaster.

For Mediumwave DXing

Without a doubt, my favorite radio for mediumwave/AM broadcast band DXing is the Panasonic RF-2200.

I mentioned in a previous post that my buddy Vlado (N3CZ) recently repaired, cleaned, and calibrated one of my RF-2200s.

Let’s just say that Vlado worked his magic and my RF-2200 now operates and performs like a brand new unit. Seriously. It’s simply unbelievable.

Not only does the Panny ‘2200 provide benchmark MW performance, it’s simply a pleasure to operate. It also produces some of the richest AM audio you’ll ever hear from a portable radio.

Of course, the ‘2200 hasn’t been produced in decades, so you’ll have to search for used ones on eBay, at hamfests, or through your favorite radio classifieds.

And, yes, I still need to finish a Part 2 blog-post about the ‘2200 repair–once I get a few details and photos from Vlado, I’ll post it!

Your Daily Drivers? Please comment!

Keep in mind that my “daily drivers” change quite a bit–the ones listed above are my current favorites and have been for a year or more.

So now that I’ve shared my daily drivers, I hope you will, too!

Is there a particular radio you reach for more than any other?  Please comment and tell us why it’s your favorite!

Sony ICF-SW100: Whip vs. DE31MS active vs. Sony AN-LP1

Guest Post by: Troy Riedel

It’s been a while since I posted a video on my YouTube Channel (but I’ve gotten the urge to make several more videos as I’ve been recently comparing my equipment – 16 portable receivers & many antennas).

I try to tune in to Radio Prague via WRMI on many weekday East Coast USA mornings from 1300-1325 UTC. Yesterday I encountered bad propagation but today was much better.  The video linked to this post is from today – 30JAN2019 recorded around 1310 UTC.

[Sorry, no tripod for this one]

People often ask, “are amplified antennas helpful” – as evidenced by this post from Thomas from a few years ago.

Without repeating the debate, just take a look at this one example.  As stated, reception was pretty good today off the little whip – but – there is an improvement using an amplified antenna.  My question: is there a difference between the two amplified antennas?  And if so, is the difference worth the price?

My TG34 is a clone of the DE31MS – purchased from Tquchina Radio & Component (ebay user: Tao Qu … they used to have an eBay store “Sino Radios” if I recall, but they stopped selling on eBay when the Post started cracking down on shipment of batteries – I actually exchanged an email with a frustrated Tao Qu when they closed the store).

I paid about $21 if I recall for my TG34 (the DE31MS is available today on eBay for as little as $17.28).  I paid over $100 for the Sony AN-LP1 (out of production now and can be listed for as high as $300 on eBay).  So … $21 versus “over $100”.  Is there a difference – and if so – is it 5x the difference – 5x better?!

You be the judge.

P.S. Just a quick slightly over 1-minute video recorded inside my house (sitting in my breakfast nook) … typically “okay” reception but not my usual Listening Post.
