Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
While watching Curious George on PBS Kids with my four year old, I learned something. In the episode we viewed–“Curious George, Metal Detective”–George needs a metal detector to find a toy robot he’s lost in the sand, but the one he’s borrowed has run out of batteries. “How about making one?” his scientist friend suggests. Make one? “It’s easy,” she explains: simply by taping an AM radio and calculator together, you can make your own metal detector. George tries it, and–lo and behold–finds his missing toy.
Really? I wondered. Was this PBS show feeding my skeptical children science fiction?
I quickly googled the notion, and apparently, it works! Watch the video below for a tutorial on building your own deluxe model:
Lessons learned? You’re never too old to learn from Curious George, PBS, or the fellow in this video. And radios are clearly even more versatile than even I guessed.
Now, back to metal detecting…Is that another soda can?
A few years ago, I heard a lot of buzz in AM/Mediumwave radio circles about a small, inexpensive radio called the Sony SRF-59. Discussions were focused on the incredible performance of this diminutive low-cost radio and how it held it own against some real benchmark receivers. Out of curiosity, I did a search on the radio to see what it looked like–I expected some Tecsun PL-like unit–and found that, much to my surprise, it’s a simple, analog, totally unassuming AM/FM walkman. Say, what?
The far biggest surprise came with my price search, however. The SRF-59 is easy to find at $14.95 US. Really, you ask? Oh, yes–and it’s readily available at many online and big box stores.
So–carefully counting my pocket change–I took the plunge, and bought one.
The radio came in a basic plastic blister pack, and it also included headphones. I can’t comment on the headphones as I didn’t even bother unpacking them; instead, I plugged my new SRF-59 into my favorite Sony earbuds.
I have to admit, the AM band on this little radio does indeed shine. Not only is the receiver sensitive and relatively selective (meaning, I don’t hear adjacent signals when tuned in), but it also has excellent audio. Amazingly, it lives up to all of the praise I had heard about it. I’m quite amazed, in fact, at how well this little unit can null out stations by rotating the radio body a few degrees. Most impressive.
Though I’m no major FM radio listener, I can also vouch for its FM performance, which is quite good.
Pros:
lightweight–indeed, one can safely say, “ultralight”
very inexpensive, by comparision
operates almost indefinitely on one AA cell
simple design, durable construction
AM (Mediumwave) sensitivity and selectivity comparable to $100 shortwave portables
because tuning is analog, it works in North America just as well as in Japan (see cons)
Cons:
tuning is analog, thus no stations can be saved to memory and there is a noticeable amount of receiver drift if listening over long periods of time
no fine-tuning mechanism means that tuning in weak stations takes precision skill on the SRF-59’s very small dial
no built-in speaker (this is a Walkman, after all)
In summary, you will regret not purchasing this radio should Sony pull it from the market without warning. While it is a walkman with the above listed limitations, it’s nonetheless a first-rate AM/MW receiver and might be a great avenue into the fun hobby of ultralight DXing.
In short, the Sony SRF-59 is a real gem. But don’t take my word for it, either–go check one out for yourself!
A great portable radio is your passport to the world while traveling, even in remote areas.
I receive a lot of emails from SWLing.com readers, quite often from those who about to embark upon international travel–sometimes to remote locations–and who are looking for a durable travel shortave radio. These travelers are looking for a basic travel radio which, while it might not need to survive being submerged underwater or dropped from a cliff, will hold up in the semi-protected environment of a suitcase or backpack experiencing some rough baggage handling.
I travel a great deal myself, and always carry a shortwave radio with me (actually, I usually take more than one). Here are some considerations I use to determine which radios go in my bag or pack, and thus make good travel companions:
Rugged enough to withstand typical suitcase/backpack travel conditions
Lightweight and relatively compact size
Supplied protective travel case
Efficient operation on AA cells, the most common batteries found in the world
Useful travel features, like auto-tuning, alarm/clock functions, sleep timer
Relatively inexpensive–if you lose your radio or it gets stolen, you don’t want it to ruin your trip
To be clear, none of the radios on the list that follows are marketed as “ultra-tough radios”–indeed, I know of no capable SW portable that is–but these do represent the most durable I’ve personally tested and used in my travels.
This Sony shortwave radio is a classic, with solid, time-tested performance, and features to please both the beginner and the seasoned radio enthusiast. It is full-featured, with excellent SSB and exceptional sync detection. I grab the ‘7600GR when I plan to do a little DXing on vacation. It has everything I need.
The Sony ICF-SW7600GR is still made in Japan and the case is metal. It feels like a very high-quality portable when holding it in your hands. The lock button is a sliding switch on the top part of the radio face–easy to turn on and off intentionally, difficult to do so unintentionally. Additionally, it comes with a decent padded case. The ‘7600GR operates on 4 AA cells. The only travel feature the ‘7600GR lacks is an alarm, and that’s okay by me; for the features and durability, I’ll keep the Sony and use my cell phone or watch for an alarm. The instruction manual is comprehensive and easy to read. Read the full review here.
Actually designed with the traveler in mind, the Grundig G8 will make for an excellent companion on your next venture. I’m quite impressed with this radio: shortwave reception is good, and FM reception exceptional. The AM broadcast band does suffer from some images (a type of signal interference in which aural “ghosts” of other broadcasts layer over the one you’re trying to hear), though still quite respectable. The G8’s audio is a little tinny out of the built-in speaker, though quite good for a radio this compact. The customary price for the G8 is $49.95, but occasionally retailers place them on sale for nearly half this price. I especially like the fact that there is a front cover on the G8 which protects many of the controls. The body is somewhat rubberized and the zip case that comes with the radio is padded and perfectly designed for suitcase/backpack travel. The G8 is also smaller than a paperback book.
The G8 does not have SSB capability like the Sony does, but it is a good product for casual broadcast listener. The G8 also has a great alarm clock function and a world time selector switch on the front: simply dial up your time zone as you cross the planet. The G8 uses 3 AA cells.
The County Comm Marathon ETFR Emergency Task Force Radio is a very small ultra-portable radio. The ETFR is similar to the earlier County Comm GP-4L, but was produced initially for the Canadian military, thus it features enhanced cold-weather operation. It is very durable–indeed, military-grade durability at least with regards to impact. To my knowledge, it is not waterproof, but it will certainly withstand your airline’s roughest luggage treatment.
The ETFR is no incredible performer, but the price is low and it is quite capable of catching the major international broadcasters–indeed its sensitivity is better than I had anticipated. The tuning is actually analog, though the display is digital, thus you can expect a little receiver drift if you keep this radio on a broadcast for very long. The ETFR operates efficiently on 2 AA cells providing up to 150 hours at 40% volume or 70 hours of illumination from the built-in LED light. The ETFR also has a built-in clock and alarm feature.
In my humble opinion, all frequent travelers should keep a County Comm ETFR in their go-to vehicle and/or travel bag.
Also (I have to admit) this radio looks very cool in the carry case that Universal sells. Together, these make a great bon voyage gift for any traveler.
My Tecsun PL-380 and the small Eagle Creek pack that also holds my Zoom H1 recorder, earphones, audio cables, external antenna, spare batteries and Kindle.
UPDATE 23 May 2012: Yes, I’ve also added the incredible PL-380 to the travel list as well. Read the full post here. Thanks for the comment, Alan!
As local AM broadcast (a.k.a. mediumwave) stations around the world struggle to find their local niche, a new global angle may be taking shape. Much like the proliferation of political talk shows in the late 80’s which began to give the AM spectrum its identity (at least here in the USA) could the AM broadcast band now be a local vector for international communities?
I found this article and story from NPR member station, WBUR in Boston. It features WILD-AM who has traditionally served the African American community in Boston. Their newest offering, however, is coming from thousands of miles away–from China:
1090 WILD-AM was the scrappy little engine that could. A small-budget radio station with big ideas with over 40 years on air, it earned a trusted place in the heart and soul of Boston’s inner city community. But now that’s all gone. The station serves a very different audience.
[…]As of June 1, China Radio International is the new sound of WILD. The station is targeting “new Americans.”
[…]One of the reasons WILD is no longer on the air is that the marketplace has changed — the competition is greater. What’s happened to WILD is not surprising to media observers like WBUR media analyst John Carroll.
“I think it’s a reflection of what’s happening in the radio market overall, a movement toward consolidation, a movement toward nationalization or internationalization, a movement away from local community presence on radio stations and more toward major conglomerates, which are much less expensive to operate,” Carroll said. “One of the issues is can anyone make the FCC care about this?”
