On this blog, I often write about selecting the “right” radio for home, boating, preparedness, off-grid living, or, of course, travel. As a result, sometimes I like to go through the mental exercise of imagining a scenario that might be, well, a touch extreme.
After all, as I’ve often said, SWLers come from such interesting walks–even hikes–of life, and often pose the most intriguing questions.
Indeed, I occasionally receive rather “extreme” questions from our readers, questions that push the limits of the hobby in the most exhilarating way, demanding highly specific needs in a radio. And (I readily admit) I thoroughly enjoy these questions. Such queries give me a chance–and good excuse, really–to be imaginative and innovative, to push beyond mere practical or monetary constraints to consider unique environments, weather conditions, durability needs, power requirements, and/or resource availability…all great fun.
If you enjoy this kind of brain game, too, check out our virtual challenge that follows–and, oh, and did I mention…
Accommodation? Tents, hammocks, and lean-tos on the trail; occasional hotel or hiker guest houses
Electricity? Other than rest days, you’ll be completely off-the-grid
Internet? You can choose to carry a smart phone with you on this hike. Since most of the trail is in rural, remote areas, Internet access will be sporadic on your journey.
Your budget? $300 US must cover all of your radio requirements (radio, antenna, batteries, battery chargers, and all accessories)
Your radio(s)–??? You’re searching for portable radio gear that can receive shortwave, AM (medium wave), and FM. You’ll also need NOAA weather radio functionality to help you plan each day on the trail and make accommodations for frequent spring and summer thunderstorms (and occasional spring snow or sleet).
Virtual scenario: Imagine you’re a recently-retired stockbroker fulfilling a lifelong dream of thru-hiking the Appalachian Trail. You have cleared out most of the year for uninterrupted hiking, starting in Georgia and ending in Maine. You’re covering all of your logistics, travel, and living expenses while on the trail.
Being an avid shortwave radio listener, you see this hike as an opportunity to spend quality time listening to radio–while hiking and camping–in remote areas that are completely removed from urban radio interference you experience at home.
Although you’re looking forward to “unplugging” from the world of stock trading, you’re still keen on listening to international and local news so you’ll know what’s happening in the world of finance and business.
It goes without saying that you’ll carry all of your supplies–your food, camping supplies, clothing, etc.–and all on your back. Minimizing your backpack weight is clearly of utmost importance.
Rather than making this virtual challenge more restrictive, these limitations are designed to make the challenge more fun and set a level playing field for all respondents.
Again, you’re limited to a (virtual) budget of $300 US to procure your supplies; ideally, this includes shipping costs of the purchase
You can select new, used or homebrew/kit gear, but must base your choices on reality (i.e., actually find item(s) online and document the price and time of availability). If you “shop” eBay, make sure you’re using the final purchase price, not the current or opening bid. If you do locate something used on eBay, QTH.com, QRZ.com or at Universal Radio, for example, include the link! (Just to add to the fun.) If you enter a homebrew radio, it should be based on something you’ve either built or used and must include a photo. Of course, you can use multiple radios, but keep in mind the amount of space and weight these will take up in your backpack.
Your main objective is to listen to international and local broadcasters and NOAA weather radio. If you’re a ham radio operator, by all means, you’re invited to include a transceiver in your trail kit (indeed, many do have AM/FM/SW reception), but keep in mind that our accomplished A.T. thru-hiker judge will base his decision on the best set up for listening to NOAA weather radio and international, local and broadcasters.
Remember, you’ll be stuck with this radio once you hit the trail! So choose something you’ll love to operate, and don’t forget your vital accessories. Note that there are many points of the Appalachian Trail that are in proximity to towns and cities; you can get additional supplies there as needed.
The Appalachian Trail is one of the longest continuously marked footpaths in the world, measuring roughly 2,180 miles in length. The Trail goes through fourteen states along the crests and valleys of the Appalachian mountain range from the southern terminus at Springer Mountain, Georgia, to the Trail’s northern terminus at Katahdin, Maine.
Known as the “A.T.,” it has been estimated that 2-3 million people visit the Trail every year and about 1,800–2,000 people attempt to “thru-hike” the Trail. People from across the globe are drawn to the A.T. for a variety of reasons: to reconnect with nature, to escape the stress of city life, to meet new people or deepen old friendships, or to experience a simpler life.[…]
The Trail is roughly 2,180 miles long, passing through 14 states.
Thousands of volunteers contribute roughly 220,000 hours to the A.T. every year.
More than 250 three-sided shelters exist along the Trail.
Virginia is home to the most miles of the Trail (about 550), while West Virginia is home to the least (about 4).
Maryland and West Virginia are the easiest states to hike; New Hampshire and Maine are the hardest.
The total elevation gain of hiking the entire A.T. is equivalent to climbing Mt. Everest 16 times.
The A.T. is home to an impressive diversity of plants and animals. Some animals you may see include black bears, moose, porcupines, snakes, woodpeckers, and salamanders.
Some plants you may encounter include jack-in-the-pulpit, skunk cabbage, and flame azalea.
About 2 to 3 million visitors walk a portion of the A.T. each year.
The A.T. has hundreds of access points and is within a few hours drive of millions of Americans, making it a popular destination for day-hikers.
“Thru-hikers” walk the entire Trail in a continuous journey. “Section-hikers” piece the entire Trail together over years.
“Flip-floppers” thru-hike the entire Trail in discontinuous sections to avoid crowds, extremes in weather, or start on easier terrain.
1 in 4 who attempt a thru-hike successfully completes the journey
Most thru-hikers walk north, starting in Georgia in spring and finishing in Maine in fall, taking an average of 6 months.
Foods high in calories and low in water weight, such as Snickers bars and Ramen Noodles, are popular with backpackers, who can burn up to 6,000 calories a day.
You’ll want to do your research before choosing gear for the Appalachian Trail Virtual Challenge! The more thought you’ve put behind your choices, the more likely your entry will be selected by our judge. Speaking of which…

Good luck and have fun!
Feel free to comment on this post if you have any questions.
A new SWLing Post reader challenge is on the way–the Virtual Radio Challenge III–and I’m especially pumped about this one. Like the previous two challenges, this one is not just hypothetical, but based on an actual query from an SWLing Post reader. Yet this one is just a bit different from the previous challenges.
What I’m really excited about is this: for the first time, there’s going to be a prize on the table for the winner!
Here’s how the challenge will work. I’ll post the query this week; if you’re interested in participating, you’ll have until August 1st to craft and submit your response via a form on the reader challenge post or via email.
I’ve already lined up an expert who is uniquely qualified to choose the best entry for this particular reader challenge.
You were tasked to track down a radio kit that would keep you in touch with the world, and potentially afford you some very unique DX. [If you haven’t read the full virtual radio challenge, including all of the limitations you might face, I encourage you to check out this post before continuing.]
Your Reader Responses
And, wow, what excellent responses–! First, I want to thank all who participated in this challenge. Much like the results from our first Reader Challenge, no two responses were identical. I sincerely hope you enjoyed this exercise as much as I enjoyed reading what you’ve sent to the SWLing Post!
Below you will find responses from readers, representing remarkable diversity in radio set-ups. Note that my comments follow; they are italicized and in bold.
Now, with no further ado…I welcome you to radio DX in Laya, Bhutan!
I would set up all this gear either on a panel or in a small box for the sake of tidiness. This, involving crimping kit, crimps and wire, could be done before departure. Say $20 for the bits.
Job just about done but not quite…. solar panels only provide power when the sun is out… need a biggish battery to accept the solar charge during the day and give it back at night.
A nice wet cell 12 volt battery will do the job but that won’t be allowed on the ‘plane..what to do??
After flying into Bhutan at Paro and busing to Thimphu I would take time out to buy a 12V automotive battery. At first I considered a couple of 6V motorbike batteries but have been advised that motorbikes are uncommon in Bhutan but cars and trucks aren’t. No probs on-carrying that by truck, horse and porter so thats the 12V storage sorted.
Connect solar panel to charge regulator to my battery to my computer power supply and radio charging cables . Throw my wire antennas over the handy tree, pour single malt, put feet up……
Total cost excluded the 12 volt battery … about $600… Oh and must not forget to replace the supplied AA’s in the PL-660 with Sanyo Eneloops and also a few extra sets as spare…. and a copy of WRTH.
I must admit a bit of an advantage with this…. my boat is an off-grid installation and my wife was in Bhutan a few years ago.
Frank, I love how simple you’ve kept this set up. You are very wise to acquire a 12V auto battery locally, when you arrive in Thimpu. While Bhutan isn’t as commercially “developed” as many other countries, you can find basics like batteries, connectors, fuses and accessories in the capital city of Thimpu. Your experience off-grid on the open sea and with Bhutan, in general, have served you well. Thanks for your entry!
from Tim Rahto
[Note: Tim was so enthusiastic about this challenge that he proposed three different kits: one with a transceiver and two receive-only.]
Your radio challenge inspired me to ignore everything else I have to do today and write you up a response. [You’re welcome, Tim!]
I know your contest refers to shortwave listening and not ham radio, but we are talking about Bhutan here. According to QRZ, there’s only 9 callsigns in the entire country, with three of those belonging to radio clubs, special event stations, or DXpeditions. With that in mind, I put my station together with transmitting as well as receiving in mind.
Option 1: Yaesu FT-857D
For a radio, I chose the Yaesu FT-857D. I have one in my truck, and it’s survived four years of mobile operation without a hiccup. About the only knock I have on this radio is that the AM bandwidth is pretty wide for shortwave listening, but you can always put it into sideband if needed. It’s small, portable, and puts out 100 watts. Perfect!
Some would say I cut corners on the antenna, but I don’t think so. Considering the remote nature of the location and the need to keep things light and mobile, I went with a simple dipole. Easy to build, simple to repair, and works pretty well. I went the ‘roll your own’ approach and bought an Alpha-Delta dipole kit and wire for the antenna, and 100′ of coax to feed it all.
Tim, no doubt you had a lot of fun piecing together your radio kits! In each case you chose quality components–a smart decision since you want longevity and reliability in the field. I think there would actually be enough financial flexibility in each case to include a small back-up portable like the Tecsun PL-380 or similar. As you must know, the Lowe HF-150 is a surprisingly small tabletop radio with excellent performance; it would be easy to slip in a backpack or suitcase. Thanks for your entries!
For power storage, I’d go with sufficient numbers of AA size LSD NiMH batteries to be wired up into several 12V battery packs for solar charging… heavier than Li-Ion, but considerably cheaper, more durable, and should easily last through 2-years, where li-ion wouldn’t.
Probably throw a $100 Kaito KA1102 radio in there. The 1103 is infuriating. A long, long spool of wire for use as antenna once setup. And other bits and pieces.
Amazon says I’m $600, or $800 including the netbook, without really trying to find good deals. Lots and lots of accessories still needed, like 12V cell phone chargers, diodes and/or solar charge controller. I’d also throw-in other comforts, like plenty of different LED flashlights and lanterns, good external speakers and headphones. Plus lots of USB thumb drives just loaded up with movies and TV.
Rex, I like the idea of the KTOR pedal power when solar conditions are not favorable. in truth, using solar requires a little pre-meditation whereas pedal power could work anytime. Thanks for your entry!
from Timothy Johnson
Hi! This is a great challenge. I would take my Tecsun PL 660 and buy a solar AA charger. (And maybe $400 worth of AA duracells!) And for my backup……My Grundig FR200!
What? No gazillion dollar receiver with a four mile wire strung up?
Correct! It’s a fun challenge in a great location. I want to use the radio I use now to see what I can pick up. It’s a good location to pick up stations from the otherside of the world that I normally can’t get, but dream about what it would be like. The PL 660 isn’t a slouch when it comes to receiving, and it has SSB and the Airband! This is a fun challenge and it’s a great time to enjoy listening to the shows, not just seeing what I can get. Up in the mountians, I would need to rely on my shortwave for news around the world. I mean, what day is complete without Radio Havana Cuba’s slant on the news? I would hope over there I could get Iran’s Voice of Justice!
The FR-200 would be my back up to use if the solar charger breaks, or it’s cloudy for awhile. It’s a great portable with a built in dynamo. Plus its fun to use. Scanning the dial on an analog dial makes for relaxed listening. Kick back, pour whatever the locals drink, and see what comes in!
As an english/science teacher, I could introduce the students to the world and improve their english skills, while they teach me some of their language.
Anyway, great challenge!
I have had a lot of experience with the Grundig FR200. Unfortunately, it’s no longer available new from Grundig, but the same model is available from sellers on eBay as the Tecsun Green 88. Not only does it work well from the hand crank (2 minutes of cranking yeilds 40+ minutes of listening), but it also runs for 80+ hours on a set of AA batteries. It’s a durable radio as well. Thanks for your entry!
a) Install Linux (Fedora), GNU Radio, and other software for RTL SDR.
b) additionally install fldigi, multimode, HFfax software, NOAA weather decoder
c) make a QFH (Quadri Fillar Helix Antenna) for 137MHz NOAA satellite reception also usefull for VHF 2m reception, upon arrival at the destination. The wooden stick and batten used for it can be available free at the destination.
Total expences = 100+52+109+5+1.3 = 267.3 $
Still one have 1200 – 267.3 = $932.70
That’s an innovative SDR kit and certainly well within budget. In fact, you would have over $900 to purchase a backup radio, batteries, power generation and antenna accessories! Thanks for your entry!
from Cap Tux
Cap’s Virtual Radio Challenge Submission
As the challenges main objective is to listen to international broadcasters and DXing you only need a small portable receiver with very little power consumption. There are a lot of very capable receivers on the market now to fit the bill.
Remember, lugging a big receiver to the other side of the world is not going to be fun (and risk it being damaged en-route).
As the village is completely off the power grid I propose to use a small portable receiver & power source with a fairly good storage capacity i.e. at least 5 good charges from a fully charged source should give you a good few weeks of heavy usage.
Receiver: Tecsun PL-660 Receiver – A very capable shortwave receiver with MW/LW/FM with SSB and runs from 4 x AA rechargeable 1.2v Ni-Mh batteries.
This receiver is also capable of running/charging from a sustainable USB power source.
The PL-660 also has an auto scan and store that will sweep shortwave and store any stations it finds into memory, saves you tuning about.
You can charge this using a USB Charger for the Tecsun PL-660.
You may be lucky and have FM reception within range (unlikely, but possible), a general coverage receiver in most cases is not equipped with VHF BCB FM reception i.e. NRD-525, IC-R75 are not equipped with VHF FM.
In order to know what frequencies you need to tune into, realistically you will only have the first season i.e. A15 shortwave schedules for your target shortwave broadcasters.
You will not know the next seasons frequencies, you will need to listen into your favourite broadcaster nearer the time to get next seasons frequencies. Load the current seasons frequencies onto your laptop, or print them off.
The PL-660 has an external antenna socket by way of a 3.5mm socket, a long wire can be used. Personally, I would take my home-brew passive Mag Loop antenna which can fold up easily, why? in case of thunderstorms that could send static down an external long wire to the receiver, rendering it unusable.
You could always hang the long wire around your room to minimise static from thunderstorms. You get a long wire bundled with the PL-660, no need to buy another,
Sustainable charging power source for the receiver:
23000mAh Li-Po battery pack with solar panel (USB port & various outlets for laptop charging).
Technically you could ditch the 3 x AA internal batteries and power the Tecsun direct from the battery pack via the mini USB cable, however, assume you would want to run it autonomously from the charger or go out and about for a spot of Dxing. I propose purchasing 12 x 2400mAh rechargeable Ni-Mh batteries.
A phone or tablet is going to be a liability if dropped, a small netbook is going to be more robust for travelling and will have a longer running time from each charge.
I would also charge the laptop from my solar charger as it has a 19.5v option for charging. The MSI Wind U180 gives around 7.5 hours on a full charge (Loads of options for a netbook though).
The stock battery is about 7200mAh which the solar charger is more than capable of fully charging.
Tecsun PL-660: £64.64 incl shipping (all other shopping items include shipping)
Total: £318.28 ($517.06)
As this is well within budget you could buy two of everything for redundancy.
If AM BCB is your only concern a Tecsun PL-310ET will fit the bill, very small/light and cheap at around £32. There is also less chance of a small £32 radio being stolen.
In the end, I would probably take both my PL-660 & PL-310 as the PL-310 will give me the flexibility when out hiking or travelling within Bhutan and also acts as a backup radio.
Cap, I’m impressed with how frugal and portable you’ve kept your radio kit. Adding the Tecsun PL-310ET is a great idea. I imagine there would be superb opportunities to do mediumwave DXing with the ‘310. As a bonus, when traveling within the country, the PL-310ET would be easy to carry and use en route. Thanks for your entry!
FunCube Dongle Pro+ and Toshiba Encore 8″ running SDR# in a London park
To recap, the tablet-based SDR set-up costs $643. My experiments with FunCube Dongle Pro+ and SDR# software have convinced me that this combination makes for one of the best shortwave listening experiences in its price range. Here are a few reasons why:
– FunCube Dongle Pro+ is a sensitive SDR.
– SDR# has an excellent noise reduction algorithm that often turns laborious DXing into comfortable listening. It also has a robust synchronous detector, which, combined with its passband tuning and noise reduction algorithms can unbury almost any station from the surrounding co-channel interference.
However, given the remoteness of the location and the fact that there is no reliable electricity grid to speak of, we need a few extras:
You may recall that in my portable SDR solution there are two sets of batteries that need to be recharged:
– Toshiba’s built in Lithium Ion battery (via its USB port)
– 4xAA batteries for the Gomadic 5V Power Pack (used for supplying extra power to the SDR)
First, let’s get a compact, foldable solar panel:
1. Powerfilm F16-1200 20W foldable solar panel
I would go with Powerfilm F16-1200 20W foldable solar panel (buy it here for $210.99). Disclaimer: although I’ve never used any of the PowerFilm products or accessories, I have read good reviews of them from other radio enthusiasts. When folded, this solar panel measures merely 27.9cm x 16.5 cm – slightly smaller than an A4 notepad. Once fully opened, however, it can deliver 20W of power (15.4V, 1.2A), enough to charge the Toshiba tablet and 4xAA rechargeable batteries simultaneously.
The spares can be used in the following ways:
– To power the backup portable shortwave radio
– To have another batch ready when the batteries insde the Gomadic USB Power Pack run out.
– Using Gomadic, to charge the tablet outside daylight hours, for more daytime listening.
Now onto charging the tablet itself. For this I would use the Powertraveller Spidermonkey 4-Port USB Charger Hub at $38.76. Again, I haven’t used this product, but according to the specifications it can charge up to 4 USB devices and accepts input power between 5V and 30V. The reviews are largely positive, so it seems like a safe choice.
5. Powertraveller Spidermonkey 4-Port USB Charger Hub
Living off the grid has the advantage of there being minimal man-made radio interference. For this reason we can use a larger antenna than in my original proposal. I suggest buying 40m of POLYS18 Copper-Clad Steel Antenna Wire from Universal Radio (the total comes to $31.44), cutting it halfway, and attaching each half to one of the two antenna terminals on the Wellbrook HF Balun, mentioned in my previous article, thus creating a dipole.
12. BNC Socket to Composite 3.5mm Male Jack Plug Adapter
The subtotal for all of the above comes to $556.71. Adding on $643 for the tablet-based SDR solution brings the total to $1199.71, just 29 cents below the budget limit!
London Shortwave: since you frequently take this same portable SDR kit to the field, I have no doubt that it would perform well in rural Bhutan. Using a PL-310ET as a backup and even thinking to bring a couple antenna accessories shows how thoroughly you thought through this exercise. Knowing the copious amounts of radio noise (QRM) you deal with in London, you might decide to stay in RF quiet Laya after your assignment is over! Thanks for your entry! Readers: check out London Shortwave’s blog for more portable SDR fun.
from “Broad Wing”
Primary Radio – Comm Radio CR 1A ($614.95)
(Radio is light weight and very durable. It also picks up SSB etc. Even though it used up half the budget I figured it would be the best to have. It has an internal rechargeable battery. I can be charged with Goal Ten Battery Pack or Solar Panels)
Secondary Radio-Kaito KA-600 Voyager ($60.00)
(This radio is my back up as it has several ways to charge the batteries, solar crank, and electric when I can get to a city that has electricity. it should also be dependable. It also has a built in flashlight. This antenna uses AA rechargeable batteries.)
(I have used this antenna and find it to be very durable and a very good DX antenna for shortwave. It is made by a gentleman called Low Bander on e-bay.)
Secondary Antenna – Tinatena All Band Active ($32.90)
(I thought that if in the dead of winter, my primary antenna broke, and there were a couple feet of snow outside, I could use this one for a backup and not have to go out in the snow or storm. This antenna uses 9 Volt batteries.)
Antenna wire 12 gauge 50 feet ($27.94)
(Wire would be used to build a long wire antenna if needed or for repairs of the Super Sloper Antenna. Wire will also be used to hook up 2- 12 Volt sealed batteries to primary radio.)
40 foot solar panel extension cable MC4 converter ($22.99)
(This kit and the extra solar panel should charge up my batteries if the weather permits. The solar panel can be hooked up in tandem to provide quicker charging times or used on separate equipment. The Goal 10 charger will charge my Comm Radio when the power is low, and I can connect the radio to the kit when the sun is out just to recharge. When the sun is not out, or I have a long time without sun, I can use the Secondary Radio to conserve batteries.)
Set of batteries sold with 24 AA 2000 mAh, NiMH Batteries low discharge ($42.34)
9 Volt batteries, 4 pack ($15.96)
2- 12Volt 7ah sealed lead acid rechargeable batteries ($32.00)
Total Cost: $1198.73 -$ I200.00= $1.27 under budget. Good for a pack of crackers to take on the plane to munch on.
I am not buying any connectors as the primary antenna comes with coax and connector. All prices include shipping and handling charges and can be received in 7-10 days. In two years I will report back to you and tell you how the trip went.
I think choosing the CommRadio CR-1a as the centerpiece of your set up is wise. The CR-1a is very rugged and engineered to last. Most importantly, you can power and charge it on a wide range of voltages (6-18 VDC). That’s power flexibility! Thanks for your entry!
from Eric McFadden (WD8RIF)
What a fun thought-experiment!
For the shortwave listening station radio, I’d buy a Sony ICF-SW7600GR portable shortwave receiver. It’s stable, sensitive, selective, provides SSB and synchronous-detector, and runs on common AA cells. It’s available for about $132 on Amazon but I’d probably buy from Universal Radio.
I’d buy an Emtech ZM-2 “z-match” tuner ($65 in kit form, $90 built, direct from Emtech) to use between the Sony and the random-length wire antenna; I’d adjust the tuner’s two knobs for maximum noise in the receiver. A 3′ RG-8X coax BNC-to-BNC jumper ($6 at Universal Radio) plus a BNC-female to 3.5mm-male adapter (#4546, $3 at Universal Radio) would be used to connect the Sony to the tuner; the wire antenna would connect directly to the tuner’s binding post. A short length of wire could be used as a ground-connection or counterpoise, if desired. I’d also take a pair of solder-less alligator clips (less than $1 each, many sources) and a solder-less 3.5mm plug (I have one of these but haven’t yet found a source for a new one; I might have to make one) in case I would want to (or need to) use the random-wire antenna without the z-match tuner.
The receiver uses for four cells; one of the panels could (probably) charge a set of four cells each day and the Eneloop chemistry would allow the charged batteries to remain charged while not in use. The second 8-pack of Eneloops and the second Powerfilm solar-charger provide redundancy. It’s unlikely that one evening’s listening on the Sony would discharge a set of cells so it wouldn’t be a problem if the solar panel needs more than one day to fully charge a set of four cells.
If I choose the kit version of the z-match tuner and don’t buy an MFJ-1910 mast, the total comes to $449.
I am an amateur radio operator and would want to take along some sort of transceiver. Given my druthers, I’d take my Elecraft KX3 and forget about the ICF-SW-17600GB but that’s against the rules of this Challenge.
Since I can’t take my existing KX3, I’d buy a YouKits HB1B Four Band CW QRP Transceiver (80/40/30/20m, $300 from YouKits), a Whiterock MK-33 single-lever CW paddle ($30 from Electronics USA), two pairs of inexpensive over-the-head stereo earphones (~$10/ea), a ten-cell AA holder (#10AAT, $7 at Batteries America), and another set of 2000mAh AA Eneloop cells. I’d use the same random-wire antenna I deployed for the listening post, and the same Emtech ZM-2 z-match tuner to match the transceiver to the random-wire. The 8-pack of Eneloops plus two cells “borrowed” from the extra set purchased for the listening post would be used to make a 10-cell battery-pack for the transceiver. Using both Powerfilm chargers would probably allow me to fully-charge ten cells in a two-day period. I’d have to balance the charging needs of the listening post and the ham station but I think it wouldbe workable.
The cost of the ham station comes to $382.
The rules of the Challenge were unclear about whether the cost of a tablet/smartphone/PC was to come from the $1200. Either way, I’d probably limit myself to a 7″ tablet such as the Nexus 7 I bought myself last year for $150. A Powefilm USB + AA Foldable Solar Panel ($80 from Amazon) could be used to charge such a 7″ tablet. (And the same panel could be used to charge cells 9 and 10 of my 10-cell ham radio battery pack, allowing me to charge the ten-pack in a single day instead of needing two days.)
The grand-total of all of this stuff comes to $1,061, leaving enough to purchase a second ICF-SW7600GR to take as a spare.
I know this is just a mind-experiment but I’d love to hear what the HF bands sound like so many miles from any RFI sources!
Eric, I like how you’ve balanced your ham radio and shortwave listening needs in this kit. While there was no restrictions to keep you from using a KX3 (both a superb transceiver and general coverage receiver), your set up allowed for more extras and back-up supplies. Since a basic kit version of the KX3 costs about $930 (shipped) it would have eaten up much of your budget. Since I own a KX3, my first inclination was to design a kit around the KX3 as well (if the budget would have even been $100 more, I probably would have). With your kit, you have a little money to spare, plenty of antenna-making supplies, a fantastic antenna tuner for both SWLing and QRP, a benchmark portable receiver and a capable four band QRP CW transceiver as well. Great job! (Readers, Eric has an excellent website devoted to ham radio and QRP–his projects are beautifully documented.)
from RS Wood
By the sound of it, this is a Peace Corps assignment. May as well ask a former Peace Corps volunteer!
I’d personally recommend you keep a low profile: traditional peoples like those you find in Bhutan will see your fancy antenna on the roof and assume you’re a spy or something. I’d go for a portable shortwave – something in the $150-$300 range from Sangean or Tecsun, as well as a $35 indoor, powered antenna (they run on AAA batteries). Buy a second radio as backup.
For internet use, assume you’re going to be offline for long periods of time. Get a netbook, not a tablet/smartphone, and one or two USB hard drives for storing your stuff. Ditch gmail/hotmail and get an account from which you can download email and store locally when you’re in town (fastmail.fm, toast.net) – look for POP3, not IMAP. Idea is: you go into town, plug in somewhere, download and store your stuff locally, and can use your machine at your house, with no connection to the internet, to write. You might be able to get a GSM modem if service extends to your post; that’s another reason to have a machine with USB slots into which you can stick a USB modem (yes, dialup) or GSM (cellphone) modem. Used netbook on ebay should run you $200; add another $200 for external harddrives you bring stocked with stuff (ebooks, etc.).
Lastly, bring as many notebooks, pens, and books as you can. Speaking from experience, you’ll find yourself doing more reading and writing, and less internet. And I repeat: keep your radio low-profile. Whip out the huge radio and antenna and your neighbors will distrust you, seriously.
Good cultural points! This is true. In the past, I have given this same advice to aid workers traveling to impoverished urban areas. Not only does a conspicuous setup attract attention, but also (sadly) theft–not just of your radio, but anything else in your house. Fortunately, I have only heard positive reports from Bhutan–houses without locks, that sort of thing. Thanks for your entry!
from Ariel Jacala (NY4G)
For starters – I would either build from scratch or buy a new Elecraft K2. Since I would be on assignment for 2 years, I would need to be able to repair my gear. A K2 is built from through hole components so it is repairable. All I would need are some spare parts for the components that are known to be failure prone – mostly diodes. I would consult with W3FPR for his recommended list of spare components from his experience of repairing hundreds of K2s. If I can find a used one with a SSB module, so much the better. I would volunteer to build one for someone else just to get the build experience.
The next thing is toss up. Cabelas sells 500 watt generator for $350 dollars or do I get a small amp. Provided I can get gasoline from the villagers, the generator will make living here at least bearable – for lights, charging batteries and another power source other than the sun. The amp goes for $300 – a Hardrock50 which I have built. Is it worth the extra 6 or 7 dB from 10 watts? You bet. In an emergency I can use the extra 40 watts or for a long overdue ragchew in English.
There you go
Transceiver, batteries, solar panel with money to spare. – about $350 left.
Ariel: Very smart of you to consult Don Wilhelm (W3FPR) as he is the most knowledgeable source of info about the K2 and any weaknesses it may have. I have a K2 and completely agree–it’s probably the most capable transceiver that can be field serviced. The only weakness of the K2 (for this hypothetical trip) is the fact that it does not have a general coverage transceiver. For any broadcast listening, you’d want to use some of that $350 surplus for a portable receiver–easily accommodated in your budget! I know you Ariel, and am willing to bet that most of your radio time would be in the ham bands! Thanks for your entry!
from Anil Raj
Spend two years in Bhutan, off-grid and with no internet… Wow! That is probably the most extreme scenario one can think of! However, not completely alien to me as I work in the energy business setting up power plants in off-grid areas http://www.omcpower.com/
These are my thoughts:
Click to enlarge.
Clearly, the single largest limitation is going to be the availability of reliable power. A quick look at a solar insolation map for the region makes it clear that solar which would normally be the most convenient source of power cannot be relied upon in this case.
My choice for reliable power would be a combination of a solar charger with a set of Eneloops and the BioLite stove since all it needs to generate useful power are twigs and sticks. It generates about 3 – 4 Watts which can comfortably power a small radio. I’m pretty sure the stove would come in handy in the winter to keep warm as well! The daily ritual of lighting a small wood fire to listen to the radio might eventually become a meditative experience… Price $ 118.00 + $130.00 + $20.00
My choice here is the Sony 7600GR. It is time tested having been on the market for over a decade. In my opinion it has by far the most robust build quality in it’s price range. SSB is a must, and the Sony performs well in this department, and the AM sync is a bonus feature. The main reason for my choice however, is the frugal power consumption – about 50 mA. The Sony also happily runs off a 5 V supply like a USB charger which simplifies the power issue significantly. Price $ 130.00 on Ebay
Headphones are a must to keep power consumption low and my choice here are the “Sleep Phones” http://www.sleepphones.com/ The fantastic thing is that these also keep your ears warm (Himalayan winters) and of course you can use them in bed without the discomfort normal headphones or earbuds usually give. Price $ 40.00
Being a ham, it is obvious that a transceiver will have to be a part of the plan. Any of the traditional general coverage transceivers available today would immediately break the energy budget and not be viable for more than a couple of weeks. Here my choice is the Mizuho MX-14s handheld. This tiny rugged 20 M transceiver puts out 2 W on SSB and CW, fits in my pocket and hardly draws any power. My plan would be to keep it for emergency use only in case a license is not possible. I have used one of these for several years and know what is possible with 2 Watts and a good antenna. Power is from a set of Energizer AA lithium batteries which can hold a charge for up 20 years.
My choice would be the HyEndFed antennas EFHW and the most suitable would be the 20 M version which would work fine as a random wire for the Sony receiver as well as and End Fed Half Wave for the transceiver. These antennas are built to a very high spec with silver plated wire with teflon insulation etc. Price including feeder and adapters $ 120.00
So, all the bits and pieces together add up to about $ 1000.00 which is comfortably inside the budget. I would definitely spend the rest on woollen socks!
Anil, this is brilliant! What I like best is that your kit is based on your experience both with alternative energy and the equipment you’d plan to use. Having built a solar house myself, I also consulted a solar isolation map when first tackling this Bhutanese challenge. You’re right: unless you have a semi-permanent PV system to trickle charge a battery anytime you have solar gain, you could be disappointed if relying on portable solar alone. Though I had heard about the BioLite, I’ve never used one. I’m very tempted to buy one now. I see where it could provide two important resources at once: heat and power. I also love the idea of the Mizuho MX-14s HT transceiver; though it’s limited to 20 meters, that would be one of the best and most useful bands if you decided to get on the air. I’ve read that the Mizuho is nearly bullet-proof. Still, like Ariel with the K2, I would consult Mizuho MX-14s users in advance of the trip and perhaps stock up on components that commonly fail. Looks like they would be relatively easy to replace in the field (with an inexpensive battery-powered soldering iron). Thanks for your thoughtful entry!
What fun! Thank you all…
I know this sort of challenge may not appeal to everyone, but I really enjoy it. This sort of exercise forces you (though safely) outside the comfort-zone of a home radio set-up. Your responses are truly innovative.
Thanks, again, for your participation! If your response wasn’t included above, or I didn’t respond to you directly, please let me know: it’s possible I skipped over yours by mistake as there were quite a few responses to collate, and my email is managed by a rather discriminating SPAM filter.
Meanwhile, if you think of an alternative set-up–or would like to add your own to this post–please comment below!
I already have more than six future reader challenges waiting in the wings: all based on real inquiries from readers. I hope to post another in the near future.
Today is the last day to submit entries for the Virtual Radio Challenge II: your opportunity to piece together the best, innovative $1200 (US) radio kit you might pack for two years in the remote off-grid village of Laya, Bhutan.
To participate in this challenge, simply comment on our original post with your suggested set-up, any links, and a brief explanation for your choices. You’re also welcome to email me directly with your response on or before Friday, October 3rd, 2014 (today). I plan to post a selection of diverse entries next week.
We’ve received some brilliant, creative entries in the Virtual Radio Challenge II: your opportunity to piece together the best $1200 (US) radio kit you might pack for two years in the remote off-grid village of Laya, Bhutan.
To participate in this challenge, simply comment on our original post with your suggested set-up, any links, and a brief explanation for your choices. You’re also welcome to email me directly with your response on or before Friday, October 3rd, 2014. I plan to post a selection of diverse entries shortly thereafter.
Shortwave listeners are interesting, creative people who do interesting, creative work: they’re scientists, veterans, corporate employees, students, retirees, volunteers, politicians, musicians, inventors, entrepreneurs, engineers, humanitarians, reporters, artists, researchers, sailors, pilots, pirates…and most seem to be travelers. But to say the least, they’re very diverse. The joy of the SWLing Post, for me, is the fascinating readers here and the great variety of questions and comments I receive from you.
Pack your bags! We’re going on an assignment!
On this blog, I often write about selecting the “right” radio for home, boating, preparedness, off-grid living, and of course travel–but sometimes I like to go through the mental exercise of imagining a scenario a little more extreme.
Indeed, I occasionally receive such “extreme” questions from our readers, questions that push the limits of the hobby, demanding highly specific needs in a radio. And, I readily admit, I thoroughly enjoy these questions! They give me a chance–and good excuse, really–to be imaginative and innovative, to push beyond mere practical or monetary constraints to consider unique environments, weather conditions, durability needs, power requirements, and/or resource availability…great fun.
If you enjoy this kind of brain game, too, check out our virtual challenge that follows:
Should you agree to take it on, you’ll need to complete it within two weeks. Why the time constraint? Let’s imagine that your flight leaves May 15th, and you’ll need to make sure you’ve received, tested, and packed all of your supplies by that date.
[By the way, this scenario is based on an actual reader question.]
Electricity: Your village is completely off the electrical grid
Internet: You have no access to the Internet in the small town where you will be living. As a teacher you can use the Internet at any school in Bhutan, though you’ve been told there is no internet access in remote Laya.
Your budget: $1,200 US–which must cover all of your radio requirements (radio, antenna, batteries, and all accessories)
Scenario: You’re serving a two year assignment as an English and Science school teacher in the extremely remote community of Laya, Bhutan. Your logistics, travel and living expenses will all be covered for you by the agency which arranges the teacher assignment. That being said, your total amount of luggage cannot exceed the maximum amount of luggage allowed by your airline: one carry-on and two check-in bags, both of no more than 60 kg (132 lbs), total. There will be some winter weather clothing made for you locally in Laya. You’ve been told that Laya is “several days” walk from the nearest maintained road.
Once you arrive, you will primarily travel regionally within Bhutan on an infrequent basis.
View of Laya, Bhutan (Source: Roro Travel)
Bhutan is a beautiful land-locked, mountainous country, nestled in the Himalayas. You will work and live in the town of Laya, Bhutan (population 3,000) as an English and Science teacher. Laya’s altitude is 3,820 meters or 12,533 feet.
Once you’ve settled in, ordering a new radio or accessories will not be an option. Repairing your radio will also be very difficult as you expect no access to electronic repair facilities. An emphasis on quality equipment is a must. You might be wise to consider a small, back-up radio as well.
You’ve allowed yourself a rather generous budget since this is such a long-term assignment. You’ve allocated $1,200 US –the price of a good laptop computer. You do not plan to bring a laptop, but you do plan to bring a lightweight tablet PC or smart phone for use when you travel regionally, in hopes that you will find internet access in other towns. Your main limitations will be:
Being completely off the grid
Weight and size of equipment
Allowance for alternative power supplies (how will you charge your batteries at home?)
Your small, one room stone cottage is attached to another similar cottage. You will be able to string a wire antenna outside, and you understand that there is even “a small tree” outside the window. Weather, at this altitude, can be extreme at times.
We’ll assume you’re starting from scratch, that you have neither radio nor accessories.
Your goal is to have the best shortwave listening set-up possible for your budget and for this location.
If you are a ham radio operator (or plan to become one), you may chose a general coverage transceiver for this assignment. There is, however, no guarantee that you will be able to successfully procure a Bhutanese license, but there is some promise. (I can assure you that if you do get on the air, you’ll need to be familiar with operating split and working pile-ups!)
Obviously, the more you understand the unique geography and infrastructure of Bhutan and its limitations, the better choices you’ll make for your gear.
You’re limited to a (virtual) budget of $1,200 US to procure your supplies; ideally, this includes shipping costs of the purchase
You can select used gear, but must base your choices on reality (i.e., actually find item(s) online and document the price and time of availability). If you “shop” eBay, make sure you’re using the final price, not the current or opening bid. If you do locate something used on eBay, QTH.com, QRZ.com or at Universal Radio, for example, include the link! (Just to add to the fun.)
Your main objective is to listen to international broadcasters, and do a little DXing.
Remember, you’ll be stuck with this radio for two full years! So choose something you’ll love to operate, and don’t forget your vital accessories.
Note that the limitations of this exercise are simply to level the playing field for everyone as well as to make the challenge a little tougher (and thus more fun!). Of course, they’re open to interpretation, but do try to honor the spirit of the game.
Your goal was to assemble the best shortwave listening set-up possible for your virtual budget of $200 US. You were tasked to track down a radio kit that would keep you in touch with the world, and potentially afford you some very unique DX. [If you haven’t read the full virtual radio challenge, including all of the limitations you might face, I encourage you to check out this post before continuing.]
Your Reader Responses
And, wow, what great responses–! First, I want to thank all who participated in this challenge. No two responses were identical. Some truly surprised me…I must say, I sincerely hope you enjoyed this exercise as much as I enjoyed reading what you’ve sent to the SWLing Post!
Below you will find ten responses from readers, representing remarkable diversity in radio set-ups. Note that my comments follow; they are italicized and in bold.
Now, with no further ado…I welcome you to radio DX on Tristan de Cunha!
from Frank Holden
First up, Frank Holden, who submitted his entry at 3:00 AM–prior to leaving on a 6:40 AM flight. Obviously, travel was on this Post reader’s mind.
Based on both my own experience and recent swling.com research I would choose a:
Duct tape (for securing joints on Squidpole and taping top of ant to top of Squidpole) $2
20 metres of wire for antenna with fitted plug. $10
Cable ties for securing Squidpole to stake. $1
Coil 3mm diam polyester line for stays $10
One dozen big tent pegs. $12
Big hammer [Available locally!]
Squidpole Antenna (Photo courtesy of http://www.perite.com/)
Total is $210 Australian, so you will get change out of $200 US.
Feed antenna up inside the Squidpole and tape at the top…. The rubber ‘bobble’ is removeable.
Maybe run a short length of coax from radio to base of Squidpole.
Make sure the Squidpole is well stayed. My experience in VP8land and Tierra del Fuego is that the constant flexing in high winds will lead to squid pole failure. Mine were secured to the taffrail on my boat… i.e. at the base and 50cm up from base…. Failed at the 50 cm point. I have also had a 5 metre high quality (marine grade) alloy whip fail in the same manner.
Utilise rest of baggage allowance with warm clothes, rum (power outages… for use during), etc.
Thanks, Frank! I love the idea of the Squidpole as it can give you a little height when trees are absent. I have used a similar telescoping pole for Ham Radio QRP operations: a Jackite pole. I’ve broken the tip section twice already due to my own clumsiness–fortunately, the tip can be purchased separately. As you suggest, I bet the winds on Tristan Da Cunha would give the Squidpole a run for its money!
The Ham It Up v1.2 – NooElec RF Upconverter converts your RTL-SDR dongle into an HF receiver.
I propose using my current setup, since a laptop is a freebie here. I use the following in my setup:
That’s $157. That leaves $43 for a 25? length of coax and two MCX adapters. Coax run is $15 (at $0.39/ft for RG-8X.) I forgot how much the adapters were, but less than the $28 left over after buying the coax run.
Downside? I have no pole to support this, and houses on the island are only one story structures. I’ll have to attach the high end of the sloper to the peak of the home where I’m staying, and I’m sure that height is less than the 25? recommended by AlphaDelta. In addition, I’ll have to plant a stake at the lower end of the sloper to keep that end the recommended 8? above ground. I also made no provision for extra power if a power outage exceeded the amount of juice in my laptop battery.
If push came to shove, I would drop the MFJ 1020B for an extra $50 to buy supports or an extra battery.
Thanks, AB3RU! I’m willing to bet that you might find something on the island to support one end of your sloping antenna. It might be a challenge to meet the 25′ recommended height, as you stated. Still, this is an innovative and quite portable option!
Here are my choices:
A 50-100m wire to be used as an antenna for SW and MW. I imagine I’ll be able to catch a few MW stations from South America or Africa. As for choosing a radio…
I’ll need a good radio which allows using an external antenna not only for SW (all of them do) but also for MW (few of them do). I think there is only one radio which fits this requirement within the budget: the Sony ICF-SW7600GR, available on Amazon.com at prices around $140. My other choice would be a Sangean ATS-909X which works very well with external antennas, but it’s more expensive.
I’ll also need two packs of 4 AA rechargeable batteries and a charger.
Thanks, Tudor! I believe your choice of the Sony ICF-SW7600GR is a very good one, as the Sony is a solid performer. It would be a challenge to find a new Sangean ATS-909X within your $200 budget–you would need to track down a used one, most likely. With the PL-660 in tow, you would then have a full $60 to purchase batteries, charger, and your antenna wire. Very workable!
It is through hole soldered so replacing parts is easy. Bring a bag of spare parts and a couple batteries. Get two headphones so that you and a friend can listen at the same time.
Thanks, KK6AYC! At $110 US, you would certainly have enough budget for spare parts, batteries, and antenna wire. While a regen receiver may not be for everyone, these do provide excellent sensitivity once you pass this rig’s learning curve for tuning. If the winds blow your external antenna around, you might have to ride that regen control! Great alternative to the typical portable–!
from John Treager
Next, John Treager, who writes:
Neat thought experiment! I’ve recently got back into SW listening after years away. I’ve been hitting your sites for two or three months and your weak station comparison really grabbed my attention but this one has lit the fire again.
[…]I’m a contract engineer who lives away from my primary residence most of the time so this challenge kind of strikes a chord. And, as I’m getting back into SWL, you’ve given me a reason to research (something engineers love to do!).
If I’m renting a room with a family on the island, headphones are a must. I’m cheap and traveling light so let’s go with Sony MDRZX100 headphones. I’ve used them for quite a while and like them. I find them comfortable for at least a couple of hours. Currently $15.09 on Amazon.
I enjoy the challenge of simplicity so, as far as an antenna goes, I would choose a simple long wire. Either a reel or one I build, $10-15. I get as much enjoyment from fussing with antennas as I do from turning knobs and dials. If my simple wire antenna doesn’t work when I get on location, then investigating and tinkering with antenna design and construction will fill the hours!
By the rules of the challenge, power is available but somewhat unreliable it sounds like. To meet that, I’m going with rechargeable batteries and enough to last for a while. AmazonBasics AA NiMH Rechargeable batteries (16 pack, 2000 mAh). Not the newest version, but should suffice for one year and 16 batteries should be enough for extended periods of no power. And, this may be a bit of a cheat, but I use AA batteries for everything, so I already have a charger!
Next, some sort of reference. I usually use either my laptop or a phone/tablet for frequencies/times from various sources, but given that there is no internet access in the residence and power may be occasionally spotty, let’s go with the World Radio/TV Handbook as a backup (I do miss Passport to World Band Radio!). I found WRTH on eBay (new, 2014 edition) for $27.24.
I assume I will have notebooks and pens for other reasons, so not included in the total.
Thanks, John! That should be enough AA batteries to keep you going well over a week with no power. Packing a WRTH makes a lot of sense. Via the island’s library Internet–however variable–you could download WRTH updates, as well.
from London Shortwave
The Global AT-2000 (Photo: RadioPics.com)
London Shortwave sent his suggestion in by tweet–a simple, proven combo:
If a laptop was coming along, I would have to use an SDR.
I would get the Afedri SDR USB-only model [see AFEDRI SDR-USB-HS above] for $159 (board only, I’d have to mount it in a sardine can). I would then use the remaining $41 for a cheap used antenna tuner and a random wire for an antenna. I think this kit would make for an excellent listening post.
Backup power would be a concern with the outages, so I am contemplating a 6-volt battery backup power system to power my Phillips 4-port USB hub (6 volt DC in requirement). From there the USB-hub will power/charge a Dell Venue 8 Pro tablet (the laptop), the Afedri SDR and maybe a USB-powered speaker? Would have to test out this backup power scheme before boarding the boat!
I think I could do all of the above for $250 including the backup power system. Although it would likely push $300 when wires, cables etc are all in (does not include the tablet/laptop).
Thanks, Princehifi! So you’re a little over the $200 budget with all of the accessories, but if you already have a laptop and tablet, I think you could tweak your set-up to meet the budget goal. I did not realize that there was a USB only version of the Afedri SDR–I might have to get one of those myself!
Here’s my list. Where can’t get it locally and I don’t have a firm shipping cost, I’ve estimated it as an additional 20%. Stuff I can get locally (Radio Shack, etc.) I haven’t added any shipping or sales tax.
(That’s right, a spare radio. Because middle of nowhere.)
Grand total: $192
Now if I’m allowed to scrounge in the parts bin for stuff like 22 gauge antenna wire, RG58, and earbuds, there might be enough left over for a SECOND spare radio and 4 more Eneloops!
Thanks, Rob–you have a plan, indeed! Well thought through! I, too, would be very curious what sort of medium wave DX I could hear in the South Atlantic, especially since you know there would be no local blow-torch stations around. I have the Grundig version of the Tecsun AN200 and find it an essential antenna for portable MW DXing.
Grand total: $156.89 (all qualify for free shipping)
I’d guess I would save the rest for repair costs in case the radio acts up. Of course, I’d take the one I already have as a spare. When in remote locations, backups are essential so I probably bought more than most people think I need. And as far as the battery charger, rapid chargers are bad for most NiMH batteries so I went with a slower charger. And don’t forget that the Tecsun can charge the batteries in the radio when not in use.
Thanks, Michael! You are erring on the side of having extra batteries and more than enough wire for antennas; there’s no way you’ll run out in your one-year stay. On Tristan, I know that locals often trade supplies: those extra batteries may turn into an antenna support!
from Kenny B
Kenny B writes:
I love your site, I’m there everyday and almost forgot to enter so here it is:
1. Kaito 1102, I have had good luck with it and it has ssb, second choice would be a Tecsun PL-380, I really love this radio and it’s a great little dxing machine but no ssb. The Kaito is 64.95 on Amazon, free shipping.
8. Radio Shack 1/8th inch miniplug for end of coax, $4.00
Wow! Thanks, Kenny B! Other than the KA1102, your complete kit is DIY–I like it! You could build the battery charger and antenna prior to leaving.
1. Receiver: Wandel & Goltermann FE-8 Spy Radio Receiver (US$ 120 at a Hamfest)
Wandel & Goltermann FE-8 Spy Radio Receiver from the cold war (mine was manufactured in 1963. I bought it at a Hamfest in Sweden a month ago for the equivalent of US$ 120.[…]
For ruggedness there is nothing else like it. It is completely sealed and constructed from a single piece of die-cast machined aluminium and stainless steel. Just the thing for wet and rainy Atlantic islands! Covers 2.5 – 24 MHz and only needs 6 Volts at 8mA. A pack of twelve AAs will fit in my pocket and last at least a year with about three hours of listening every day. No adapter, no charger. The razor sharp 3.1 kHz Collins Mechanical Filter is not ideal for music but hard to beat for general news and SSB utility listening. Like the famous Collins R390 it uses a mechanical “digital” dial accurate to 1 kHz which also glows in the dark. […]It is smaller that a Tecsun 660 though it weighs a lot more. More about this radio here http://www.cryptomuseum.com/spy/sp15/fe8.htm
2. Antenna & Earth (US$ 15 in any electrical store)
Random length PVC insulated wires with a banana plugs- total 50 meters. The radio has a hi-impedance input and is sensitive enough to do a great job with just 20 m of wire. The rest is spare.
I’m all set for the trip now with $10 to spend on a supply of chewing gum. I know that this radio setup can easily deal with whatever is thrown at it… the question is if I can!
Thanks, Anil! Wow…I never saw that spy radio coming! It does look like an ideal radio for prolonged use and for pretty much any environmental conditions. I hope you realize that I will be bugging you (okay, pun intended!) to provide us with a few broadcast recordings from the FE-8. It’s certainly got my interest piqued!
Now, that was fun! Thank you all…
I know this sort of challenge may not appeal to everyone, but I really enjoy it. This sort of exercise forces you (though safely) outside the comfort-zone of a home radio set-up. Your responses are truly innovative. I only wish the Post could actually send our participants to Tristan de Cunha to try their set-ups out first-hand! I, for one, would love to come along…
Thanks, again, for your participation! If your response wasn’t included above, or I didn’t respond to you directly, please let me know: it’s possible I skipped over yours by mistake as there were quite a few responses to collate, and my email is managed by a rather discriminating SPAM filter.
