August 2019 Rockwork DXpedition

Many thanks to SWLing Post contributor, Gary DeBock, who shares the following guest post and update from the August 2019 Rockwork DXpedition:


Gary DeBock DXing with Craig Barnes at the Rockwork 4 ocean cliff near Manzanita, Oregon, USA

Once again the largest FSL antenna collection on the planet made its way across the Columbia River bridge during an overnight trip to NW Oregon, finally being deployed at the original Highway 101 plunging cliff turnoff– Rockwork 4. There has been a drastic decrease in the squatter population, so that Craig Barnes and I were able to easily set up all four PVC bases for all-out DU-DXing at the dream site this morning (see photo). Unfortunately Chris Black came down with a health issue at the last minute, and needed to cancel out.

Craig and I had some excellent signals from the regulars (including 531-More FM, 558-Fiji and 1017-Tonga), although it wasn’t quite a stellar morning for rare DX. We were kind of spoiled last year with 1017-Tonga staying a S9 practically throughout the session, but this morning it was “only” at S9 for a few minutes at a time. This meant that as soon as I notified Craig of 1017’s potent status, the signal tended to nosedive. Maybe the cumulative effects of humidity and salt water exposure are beginning to take their toll on the Tongan big gun? 558-Fiji showed up with decent signals for a couple minutes at a time, which meant that Craig got the short end of the stick after I notified him of the potent signal. 531-More FM hit an awesome S9 peak around 1312 (including the usual split-second female ID), making it once again seem totally bizarre that no trace of the 2 kW modern rock station has ever been received at Grayland for the duration. The Rockwork Cliff is typically focused in like a laser on New Zealand, and this was a typical morning!

Review of the C.Crane CC Buds Solo In-Ear Single Earbud (and a chance to win one!)

A few weeks ago, C. Crane sent me one of their newest radio accessories: the CC Buds Solo Single Earbud.

Here’s the description from the C.Crane product page:

Single Earbud Optimized For Voice

The CC Buds™ Solo single earpiece provides a unique advantage over traditional earbuds because it allows you to interact better with others while listening to radio, podcasts or audiobooks (your boss will love you). The integrated stereo to mono plug works with smartphones, radios, tablets, and most other audio devices.

The Solo can give you a safety advantage when running, biking, or walking because you are more likely to hear if danger approaches. The cable is Kevlar™ reinforced for maximum durability. It is perfect for scanner radio listening. Can work well for law enforcement when greater awareness is needed.

Audio is tuned for superior voice clarity. Included are three silicone and three compressible foam covers––sized small, medium, and large. The small covers usually fits a small ear comfortably. Standard 3.5 mm headphone jack. Cord Length 48″.

At first blush, the idea of a single earpiece smacks of vintage solid-state radios. I’ve a number of classic portables that were designed around a hard-plastic single earpiece–anyone else remember those?

In fact, my Sony ICF-5500W (above) even has a little compartment to house its custom earpiece.

The Sony ICF-550W’s unforgiving 1970s era earpiece.

In my youth, I carried a hard plastic single earpiece with me everywhere, especially at school, because it made listening to the radio and still having some situational awareness possible. [Unfortunately, I was known to listen to the radio during classes…what a renegade I was back then!]

If you, too, used those hard plastic earpieces, I doubt you’d have ever described them as “comfortable.” I never found them even remotely so. Those earpieces were functional, but the audio they produced was tinny and it was always difficult to keep them in my ear.

Think of the CC Buds Solo as the earpiece we all wish we could have had back then!

The Solo includes numerous earpiece options, a carry bag and owner’s manual.

Here are some of the CC Buds Solo pros:

  • The audio quality is superb for spoken word
  • The earpiece is very comfortable (see notes below)
  • The audio plug allows for mono listening on stereo devices (obviously a must in 2019)
  • Features a super-strong Kevlar-reinforced cord
  • Includes a clothing clip that acts as strain relief
  • Ships with a small, soft carry bag

So does the Solo deliver what it promises? Yes, it does.

What I really love is the number of soft silicon and foam earpieces that ship with the Solo: a total of seven options, when including the default earpiece.

If you’ve ever used in-ear earbuds, you’ll understand the importance of swapping out the soft earpieces to a size that best suits your ears––that is, to a size that makes for a comfortable seal.

The Solo might also be useful if your hearing is a bit better in one ear than the other.

Unlike single earpieces of old, it’s actually a pleasure to use the CC Buds Solo earpiece.

Before using the Solo, I would often wear only the right earpiece of my stereo earbuds when I needed to be able to hear the environment around me. This obviously isn’t ideal because the left earpiece would dangle, catch on my shirt or otherwise get in the way, and often lead to jerking out the right earpiece. Not to mention, it led to an awkward muffling (or altogether missing) of some of the sound in that other dangling earbud when stereo sound is split or processed differently for each ear. Clearly, not the best way to listen.

Note the adjustable clothing clip.

Now, when I’m driving, working, or walking, I can use the Solo clipped it to my shirt; it’s a more simple and annoyance-proof solution that allows for greater mobility and permits me to hear all of the intended sound.

I’ve only used the Solo for spoken word; primarily AM/SW broadcast band listening and for listening to podcasts.

These days, while I’ve been at work on a home renovation, podcasts have become an essential part of my day by helping me pass the time while painting, sanding, cleaning, mowing, doing yard work, or carrying out other tedious tasks. A good podcast definitely keeps it fun. The Solo makes podcast listening easy.

And of course, the Solo is also a great solution for listening to audio books, too.

I’ll admit, when I first saw the product announcement for the CC Buds Solo, I was curious if there’d still be a market for a mono earpiece. I suppose I proved it, myself, as I have found it quite useful when I don’t need the total isolation or stereo sound from two in-ear earbuds.

Well played, C.Crane!

The Sangean PR-D17: An AM/FM stereo radio designed for those who are visually impaired

Many thanks to SWLing Post contributor, Doug Hunsinger, who notes that Universal Radio is now shipping the Sangean PR-D17.

The PR-D17 has a unique design to make operation easier for those who are visually impaired. Per Universal Radio:

It has high-contrast, large yellow rotary tuning and volume control knobs, preset buttons with raised symbols to aid in identification and thoughtful voice prompts of all controls that announce all functions in English or Spanish.

It has a large and easy-to-read backlit LCD display that highlights RDS information, frequency, signal strength, battery status and alarm symbols. It has a 200 mm ferrite AM antenna for the best possible AM reception. The controls are very easy to use and you get 5 presets for AM and 5 for FM. And you can auto scan stations. The RDS technology can display station name, call sign, song title or other transmitted information, plus it can set the clock automatically. There is a stereo mono switch. There is a built in clock timer with sleep function and humane wake up system to buzzer or radio. The left side of the radio has an auxiliary input and a stereo earphone jack. The perfect solution for the radio enthusiast who is visually impaired.

“One possible version of AM radio’s future”

(Source: LA Daily News)

Radio: Is that an AM digital signal I hear? No, but it could be.

by Richard Wagoner

One possible version of AM radio’s future was posted on a Facebook group called “I Love AM Radio.” It came from group member Steve West and was a recording of WWFD/Frederick, MD as received on a radio in Beacon Falls, CT. This is a driving distance of about 320 miles via I-95; as the crow flies it’s probably closer to 275. Still very impressive.

Of course, long-distance AM radio reception is not new … people have been listening to distant stations since radio broadcasting began in the 1920s. In my case, when I was young and before I even knew what phenomenon I was really experiencing, I remember picking up stations at night from great distances on my tube table radio, then wondering why I could not hear them during the day.

I also wondered why I picked up a buzz sometimes … turned out that was due to my Dad using a fluorescent light in his office down the hallway from my bedroom. But I digress.

What makes this recording intriguing is that WWFD doesn’t transmit analog audio like most stations. Instead, they are all digital, under special permission of the FCC. Only those with HD radios can hear them. West is demonstrating that long distance digital AM radio reception is indeed possible, and — perhaps (though it may be wishful thinking) — AM radio could be better than FM from a practical standpoint.

All-digital is a mode of the HD Radio system that uses the space formerly used for analog broadcasting and puts the digital signal there instead of sandwiching the digital around the analog as with the hybrid system currently in use on all other AM HD stations, which locally includes KNX (1070 AM), KSUR (“K-Surf” 1260 AM), KFWB (980 AM), and KBRT (740 AM).

The problem with the hybrid mode is that the digital portion of the signal extends out far enough from the main frequency of a station and thus can cause interference to other stations nearby. Hybrid mode thus limits the digital signal to a fraction of a station’s broadcast power.

All-digital, being centered on the frequency, allows a station to broadcast the digital signal at a station’s full power, permitting better coverage, less interference, and better sound quality.

At least that’s the theory. Right now more testing is needed, primarily to see what happens when more stations are using the system. The problem is the all-digital system is not yet authorized without special permission, and of course, many stations would be reluctant to try it, as doing so means losing every listener without an HD radio … most of the potential audience.

West’s recording is not perfect. The signal is like any digital signal — as on your computer or your digital television, the signal is either there … or it is not. Being received at such a great distance the reception is not perfect and cuts out, but as I said, it does show some great potential.[…]

Video Demonstration of Gary DeBock’s 3″ Baby FSL Antenna

Many thanks to SWLing Post contributor, Gary DeBock, who shares a video of his latest Ferrite Sleeve Loop (FSL) antenna: the 3″ Baby FSL.

Gary Notes:

The new design 3 Inch (76mm) Baby FSL antenna is the smallest, most compact and lightweight of the “airport friendly” FSL’s developed here recently, but it provides a very potent inductive coupling boost for weak AM-DX signals.

This demonstration video shows its huge boost to a weak daytime DX signal from 1070-CFAX (10 kW in Victoria, BC, Canada) here in Puyallup, WA, USA:

Most impressive, Gary! You’re right: that design is compact enough that it should even fit the bill for my one-bag travel philosophy. I think I might have to build one of these!

RNZ: No plans to replace AM radio mast in the Cook Islands

(Source: RNZ via Michael Bird)

The Cook Islands Investment Corporation says there are no plans to replace an AM radio mast that is to be dismantled on Rarotonga.

The mast at Matavera, built with New Zealand aid money many years ago to provide a signal to the outer islands, is rusted through in places and in danger of collapsing.

Pupils from an adjacent school have been moved to ensure their safety, while plans are made for the dismantling.

In a statement the CIIC says with the rollout of FM radio and the ability to digitally stream events of national importance, the AM signal is no longer required.[…]
