Winner of the Virtual Radio Challenge III

1 Reply

Dennis Blanchard (K1YPP), author of Three Hundred Zeroes: Lessons of the Heart on the Appalachian Trail, recently contacted me from the road, en route to another lengthy trail in Vermont.

Before this latest hiking expedition, Dennis spent many hours pouring over the Virtual Radio Challenge III entries, looking up weights and specifications of radio gear and accessories…And the upshot? He’s chosen a winner of our Reader Challenge.

Again, in summary, a participant’s goal was to find the best and most portable radio gear to receive shortwave, AM (medium wave), FM, and NOAA weather to support a long through-hike on the Appalachian Trail, to plan each day’s hike, and to make accommodations for frequent spring and summer thunderstorms (as well as occasional spring snow or sleet)…all for a budget of $300 US. [Read full details of the Challenge by clicking here.]

This year, Universal Radio rewarded–and has already dispatched!–a brand new CountyComm GP5/SSB portable receiver to the winning entrant.

Below are Dennis’ comments, along with those of the Challenge winner.

I’ve just spent about five hours going over the entries. There are several that are very good…indeed, Challenge participants obviously put lots of thought into their entries.

It was really tough to decide, but I had to go with most practical.

Weight is a big consideration for me, and that leaves out solar panels, hand crank generators, and the like.

What most don’t realize is that the AT has a nickname: “The Long Green Tunnel.” This eliminates solar panels because there is little sun to be had, as you’re in the shade most of the time. By the time you get to camp it is usually too late in the day for any charging, and wearing a panel just doesn’t do any good because of the shade (and weight).

Not only is weight an issue, so is space in the pack…hikers need all the room they can get for food, and in the cooler weather, heavy clothes.

Anyway, out of five finalists, I would have to go with Eric McFadden (WD8RIF).

Eric’s winning entry

So, what did Eric choose? The following is Eric’s winning entry, beginning with his radio choice and following with a clear, practical explanation for it:

C.Crane CC Skywave, AM/FM/SW/Air/WX, $89.95 at Universal Radio

Sangean ANT-60 Roll-Up 23′ Antenna, $12.95 at Universal Radio

Energizer L91 Ultimate Lithium Cells, AA, 12-pack, $17.45 at Amazon

“The C.Crane Skywave is small (4.75″ x 3″ x 1.1″); light (5.5oz); power-stingy (30mA with headphones); and receives AM, FM, SW, NOAA Weather, and VHF Aviation.The Skywave runs on two AA cells, and comes with a case and CC Earbuds.

The Energizer L91 Ultimate Lithium AA cells provide 1.5v at approximately 3000m Ah, weigh 1/3 that of an alkaline AA cell, and last several times longer than an alkaline cell.

The Sangean ANT-60 would be tossed over a handy tree-limb and clipped to the Skywave’s whip antenna when the Skywave’s built-in 16″ whip isn’t quite adequate for listening to a shortwave broadcast station.

The purchase price of the Skywave, six pairs of Ultimate Lithium AA cells, and ANT-60 would be about $121 plus shipping, well under the $300 limit. The entire station should be small enough and light enough for easy carry in a backpack. If the twelve Ultimate Lithium AA cells don’t last the entire hike, enough of the budgeted $300 remains to purchase more cells (either Ultimate Lithium or alkaline, as available) along the route.”

To this sensible explanation, Eric adds:

“Being a ham radio operator, I’d want to have a ham rig along, too. While I’d love to be able to operate HF CW along the AT, my Elecraft KX3 is too large and heavy to carry that far. However, my current Yaesu FT-60R 2m/70cm HT and Diamond SRH77CA whip should travel nicely clipped to a backpack strap and would serve as a back-up receiver for NOAA Weather and be available for pedestrian-mobile QSOs (chats) and calls for help, if needed.

In order to save weight and not have to hassle with charging batteries, I’d leave the NiMH pack at home and carry the FBA-25 six-cell AA holder and stuff it with additional Energizer Ultimate Lithium cells in order to save weight.

Since the C.Crane Skywave already meets all the requirements of the Virtual Challenge, and since I already own the HT, battery holder, and antenna, I won’t consider the cost of the HT, antenna, and batteries as part of the challenge.”

About Eric’s entry, Dennis notes:

Eric’s solution is small, lightweight, and does everything needed. He speculates that he would also bring along his Yaesu FT-60R, but didn’t feel he could include it because of cost. Curious, I looked it up on Amazon; should he take it along, this addition would still keep his total well under the $300.00 limit.

This would provide Eric with two receivers, [the ability to enjoy] ham radio communications, and not much weight to haul. He includes the AA Lithiums, and I have to say that, without a doubt, these are the finest hiking batteries out there: they’re light, last forever, and are readily obtainable. I only had to change mine out once on the entire, six-month AT hike, and I was on the air a lot.

Several of the other entries were winners also great; I basically had to use a dartboard to pick a winner. Good thinkers out there, especially considering none of them have actually ever done a hike of this magnitude.

Congrats, Eric! Thanks, Dennis! And more to come…

Congratulations to Eric McFadden for such a well thought-through entry!

I must say, I don’t envy Dennis in making this selection: it was obviously a challenging process on his end, too, and I’m glad I didn’t have to make it!

Dennis informed me that he plans to post and comment on some of his favorite entries in a few weeks, once he completes this latest multi-week hike. We will, of course, post his comments along with the finalist entries.

Note that when I originally received the reader inquiry which prompted the idea behind this Reader Challenge, the CC Skywave had not yet entered the market. Yet several of you chose it as your sidekick for the Appalachian Trail; clearly, clever minds think alike. Obviously, a radio that would function well on the Appalachian Trail would also be a great radio for your BOB (“bug out bag”), go kit or emergency supplies.

Thanks again to Dennis Blanchard, our intrepid judge, thanks to Universal Radio for the great prize, and many, many thanks to all our Reader Challenge participants, who made this process even more exciting and challenging! Meanwhile, don’t worry if you didn’t win the CountyComm GP5/SSB this time; we’ll soon have another opportunity to win one of these handy rigs in a completely different–and fun!–way.

It might not be your radio: poor propagation

16 Replies

Lately, I’ve had a number of emails from new readers that read something like this:

“I just purchased a new portable shortwave receiver, but I can’t seem to hear anything on it other than the strongest of stations. Should I return this radio? Am I doing something wrong?”

The SWLing Post attracts a lot of new shortwave listeners–which is terrific–but there’s nothing worse than being excited about a new hobby (and new radio) only to find that you can’t hear much of anything.

But right now, it may not be your fault–nor your radio’s.

Propagation conditions don’t get much worse than this.

There are many factors that influence what you can receive, so I typically send new listeners to this article, which is full of tips to help you get the most out of your radio.

But lately, even if you follow all of these handy tips, you may still find it difficult to receive distant stations–especially during daytime hours. The fact is, for the past few weeks, we’ve been experiencing fairly dismal shortwave radio propagation conditions.

How can we tell? Well, the K index–a scale from 0 to 9 which indicates the magnitude of geomagnetic storms–“K0” equating a quiet magnetic field, while “K9” indicates extreme storms–has risen to K6 and even K7 for the past two days, unusually high, indeed. The result? In radio terms, such unsettled conditions mean that shortwave signals simply can’t effectively propagate across the globe. To add insult to injury, sun spot numbers–which can indicate effective radio propagation–have also been somewhat low.

I understand how Post readers are feeling. I’ve been particularly sensitive to the crippling effects of the geomagnetism during this weak cycle, as I’ve been attempting to hear the elusive Radio Nacional Arcángel San Gabriel in Antartica…alas, not really possible right now.

Should we just give up, then, letting the sun and geomagnetism rule the day–? Not at all! Typically, these periods come and go within a matter of weeks. No worries, readers; you’ll soon find that your radios work just fine. In fact, at the conclusion of poor solar conditions, there are often excellent band openings…

The take-away here? Just stay tuned! Better listening conditions await.

A repair story: Vlado’s fix for the classic Sony ICF-SW100

54 Replies

In June, I made a small leap of faith and purchased a (dead) Sony ICF-SW100 from Universal Radio (see the listing on right).

ICF-SW100-Used-NonWorking You see, for many years, I’ve dreamed about owning this wee little receiver, now a classic among tiny radios, but used ones are typically too expensive for my modest budget.

This time, seeing the ad at Universal, I spoke with Universal Radio directly to obtain more details about their defunct unit; while they simply didn’t know what was wrong with the Sony, they were able to very accurately describe its cosmetic and functional condition…I took a deep breath, and decided to take a chance on it anyhow.

In full disclosure, I have a secret weapon in my camp: my talented friend, Vlado (N3CZ), who is not only the most adept electronics engineer/technician I’ve ever known, but one who truly welcomes a challenge. The thought had occurred to me as I admired the wounded Sony, Wonder if Vlad would like to take this on–?

The answer, of course, was Yes! So I dropped the DOA Sony off at Vlad’s home last week. He disassembled the radio, only to discover that my ICF-SW100 was a victim of the (dreaded) damaged ribbon cable.

A short history of the Sony ICF-SW100 and SW100S

These radios are indeed brilliant, incredible performers for their miniscule size. Yet the first generation of ICF-SW100 radios–those produced before the fall of 1997–have a design weakness: the ribbon cables which connect the upper and lower portions of the radio’s clamshell design eventually fail. Multiple openings and closings bend and cut the cables, rendering the otherwise remarkable little radio useless.

SWLing Post contributor, Dan Robinson, recently shared his knowledge about the ICF-SW100 series. Dan notes:

SW-100 Seekers Beware

As shortwave veterans know, the classic SONY miniportables — SW-1, SW-100(S) and SW-07, represented some amazing technological achievements. SONY managed to shrink some fantastic technology into these receivers, including (with the last two in the line) — SYNC capability. The SW-07, which was the last of these receivers, still brings some high prices on Ebay.

But if you are searching for the ICF-SW-100S there are some things to consider and beware of. As everyone knows, the SW-100 suffered from the well-known ribbon-cable failure problem. SONY addressed this problem in later serial numbers, and changed the design of the radio case.

Modified SW-100s have a notch where the top cover meets the base.

There are some dishonest sellers out there who are trying to pass off older version SW-100s as modified ones. Usually, the tip-off is that the photograph in the Ebay auction will be dark or out of focus, so it’s hard to tell if the radio is the modified version or not.

It has become quite rare to find an original SONY modification kit, which includes a new top cabinet of the SW-100. And some sellers are trying to get as much as $300 for these, though they rarely sell at this level.

This repair kit was on eBay at time of posting.

ICF-SW100 modification kit found on eBay at time of posting.

It’s also becoming rare to see SW-100S radios new-in-box. I had two of these, sold one and kept the other.

If you’re after one of these marvel radios, do what everyone should do when considering items on Ebay — ask many questions about [the] cosmetic condition, accessories, serial numbers, etc.

Universal Radio, a trustworthy seller I know, had fully disclosed the model number and problems with this radio, so I knew exactly what I was buying. Dan has a very good point, though: unless you know the seller to be honest, do your research and ask questions!

The ailing ICF-SW100

Vlado discovers the faulty ribbon cable (click to enlarge)

Back to my ailing unit: Vlado delivered the news about the ribbon cable via text message, and though I was well aware that the chances were high that was the ribbon cable, I was a little bummed, to say the least, to get the formal diagnosis.

Why? As Dan mentions above, you’ll find that the SW-100S upgrade kit Sony produced in the 1990s is no longer available new; sellers typically list these kits at prices in excess of $300 US. Out of my budget.

But Vlado, ever the intrepid engineer, had no idea I would be disappointed with this news; he was just giving me this FYI via text. Indeed, he seemed entirely unfazed, as in, hey, no serious internal damage here…

Another hour passed. Then came another message from Vlad; this one simply said: “Call me.”

Oh no, I thought. But I called, and Vlado answered cheerfully, “Hello? Tom, is that you? Sorry, I can’t hear you very well because your SW100 is playing too loudly. Hang on–let me turn the volume down!”

Vlad installs the replacement ribbon cable (click to enlarge)

“What!?!” I responded, in utter disbelief.

Yes, he’d got it working! It seems that Vlad had unearthed an old DVD player in his garage that he’d kept merely for parts. He opened it up, identified a ribbon cable with the right pitch, then cut and folded the cable to fit into the SW100. Ingenious!

That’s Vlado for you!

And should I be interested in replacing this used cable with a new one–or in repairing other Sonys–Vlad directed me to eBay listings for new cables which only total about $20, shipped. Truthfully, I’m in no hurry, as this one is functioning perfectly and changing out the ribbon cable seems to have no effect on stored memories, etc. With a single affordable eBay purchase of multiple cable sets, it occurred to me that Vlad would have enough replacement cables to repair the SW100 many times over…

So I bought the cables. (This one for the narrow cable and this one for the wider one.)

My “new” Sony ICF-SW100

Needless to say, I’m very pleased with my “new” (to me) SW100. It’s a little masterpiece of receiver engineering in such a tiny package. And since the ICF-SW100 is unquestionably the smallest portable I own–and is one of the few I own with a proper line-out jack–it may very well become my go-to radio for one bag travel.

It’s in the bag: listening to the ‘SW100 before I pack it for my next trip!

Stay tuned the review…

Vlado’s radio E.R.: the doctor is in

As I’ve said, Vlad is one of the most adept repair technicians I’ve ever known. At my prompting, he’s kindly agreed to let me promote his services here on the SWLing Post. Vlad acknowledges that he “likes a challenge,” adding that he enjoys nothing more than making repairs even when”parts are scarce” and radio”surgery” is required. Moreover, his bench fees will be quite reasonable, especially considering what you receive: new life for a failing radio. So, if you’ve got an ailing rig on your hands, and don’t mind waiting for Vlad to get to it, send it to his radio emergency room, where radios (like my Sony) have life breathed back into them once again.

Long live the Sony ICF-SW100! And long live Dr. Vlado, who makes this possible with his creative (and nearly miraculous) repairs.

To contact Vlad, simply contact me with a description of your radio and its problem and I’ll put you in touch with Vlado.

Rhode Island’s WWII farmhouse monitoring station

Many thanks to SWLing Post reader, Mike (AC4NS), who shares a link to this fascinating article by Tom Mooney? in the TheProvidence Journal. Here’s an excerpt:

“There was nothing remarkable to see on Chopmist Hill in 1940 when, a year before the Japanese would attack Pearl Harbor and bring America into the war, a Boston radio technician by the name of Thomas B. Cave drove up Darby Road.

[…]Cave worked for the Intelligence Division of the Federal Communications Commission, charged with finding a hilltop in southern New England that could serve as one of several listening posts to detect radio transmissions from German spies in the United States.

What he discovered up at William Suddard’s 183-acre farm was nothing short of miraculous.

Because of some geographic and atmospheric anomalies, Cave reported he could clearly intercept radio transmissions coming from Europe — even South America.

As a Providence Journal story revealed after the war, military officials were initially skeptical. They wanted Cave to prove his remarkable claims that from Chopmist Hill he could pinpoint the location of any radio transmission in the country within 15 minutes.

The Army set up a test. Without telling the FCC, it began broadcasting a signal from the Pentagon. From atop the 730-foot hill in the rural corner of Scituate, it took Cave all of seven minutes to zero in on the signal’s origin.

In March 1941, the Suddards obligingly moved out of their 14-room farmhouse, leasing the property to the FCC.

Workers set off erecting scores of telephone poles across the properly, purposely sinking them deep to keep them below the tree line. They strung 85,000 feet of antenna wire — the equivalent of 16 miles — around the poles and wired it into the house.[…]”

Obtaining QSLs from AM broadcast stations?

13 Replies

SWLing Post reader, Paul Grodkowski, writes:

“Just a quick question to anyone at the SWLing Post:

Is the practice of sending a reception report to a AM broadcast station in return for a QSL card still accepted in the age of the internet ?

So many stations are broadcasting online now that I wonder if they have QSL cards at all?

I just want to keep up with the times and not bother busy people at radio stations and look out of date, yet at the same time would like to confirm report of reception.

Any information would be greatly appreciated.”

Thanks for your question, Paul! I’m no expert on AM broadcast QSLing, but I’m pretty sure many mediumwave stations still respond to listener reports. Indeed, I believe there are even radio enthusiasts who act as QSL managers of larger clear channel stations (CFZM comes to mind).

Of course, one brilliant resource for all things MW DX is the National Radio Club (NRC).

Readers: Can you help answer Paul’s question? Please comment. Also, if you have some AM broadcast QSL cards, please contact me as I would love to post some.
