Author interview: Dennis Blanchard’s (K1YPP) “Three Hundred Zeroes: Lessons of the Heart on the Appalachian Trail”

Dennis Blanchard (K1YPP) at Four Days In May 2012

This year, at the Four Days in May (FDiM) Dayton QRP gathering, I had the pleasure of meeting Dennis Blanchard (K1YPP) and his wife, Jane, as Blanchard signed copies of his book, Three Hundred Zeroes: Lessons of the Heart on the Appalachian Trail. I had previously heard about Blanchard’s book, and it was great meeting the author in person.  Both he and his wife were most friendly, and I instantly felt a connection–after all, he is a fellow QRPer!

As a result of this meeting, I recently decided to purchased a copy of Three Hundred Zeroes on my Kindle eBook reader. Though I’ve always been a fan of turning pages on a traditional book, the eReader does afford one instant gratification, as you can order it on-the-go and start reading immediately.  And that’s exactly what I did…

The result? I’m very glad I took the time to read Blanchard’s Three Hundred Zeros.  Though I don’t like to spend much time away from my young family at present, I’ve always thought it would be a wonderful challenge and adventure to through-hike the AT (Appalachian Trail); reading this book was a vicarious opportunity to do so. Indeed, my favorite trail, the BT–the Bartram Trail, which follows the path of early American naturalist and explorer William Bartram–which I hike when I can, and whose NC chapter I’ve served as a board member for nearly 10 years now, parallels the AT at different points.  So the temptation to hike (and QRP, of course) continues.

“This photo was taken in NJ. Shortly after I took these photos, and walked down the trail about a 100 feet, a bear came over to check the table to see if I had left anything.” (Photo: K1YPP)

Blanchard’s book gives me hope. Three Hundred Zeroes is a well-documented, informative, and–despite his truly serious heart condition–often humorous journal-style account of his successful thru-hike of this 2176 mile trail. His writing style is very informal and likeable, focusing on the many personal interactions that make the trail hiker’s experience unique, and interweaving his day-to-day accounts with trail lore and history.

In contrast with the arduous journey Bill Bryson describes his well-known (and hilarious) book, A Walk in the Woods, in Three Hundred Zeros Blanchard calmly and routinely deals with misadventures and hair-raising encounters with wildlife, rolling with the punches and somehow emerging unscathed. He describes the journey as “long stretches of boredom, punctuated by brief moments of excitement” in the lively and unpredictable form of bears, mice, snakes, and even other hikers, to some degree. Blanchard was obviously a great hiking companion, thus rarely hiked alone–no doubt, other hikers sought his company.

With QRP in mind, I had a few questions for Blanchard after reading his book.  He has kindly taken the time to respond to QRPer‘s questions, as follows.

QRPer:  I always thought that the AT would be a lonely place, but your book certainly changed my mind. Were there many stretches of trail where you were completely alone while trekking or camping at night?

Blanchard: There were times when I was alone for extended periods. However, “alone” is a relative term. Throughout the day I would encounter other hikers going in the other direction, or people that were slower or faster than I. In 180 days on the trail, I think I had three nights when I camped alone.

“2007-Damascus, VA was where I operated Field Day in 2007. It was shortly after this that I left the trail for the heart surgery.” (Photo: K1YPP)

QRPer: What was your favorite stretch of trail?

Blanchard: That’s difficult to answer…The trail is so varied and weather can change one’s views of any section. For me, it was a coin toss between the New Hampshire White Mountains and the 100 Mile Wilderness in Maine. The remoteness of both areas was just so spectacular. Of course the high altitudes made for great antenna opportunities as well.

QRPer: Did you bring a radio to listen to local AM/FM or shortwave?

Blanchard: For most of the hike, I carried a Yaesu VX-1R 2/440 handi-talkie. I think I used it about three times on two-meters. In a few situations, such as up in the White Mountains, I used the VX-1R to tune in NOAA for weather news. It also has AM/FM and on a few very rare occasions, I tuned into local stations for news. Would I carry it again? I don’t know. It is wise to have something for emergencies, and the radio wasn’t too big or heavy, but it was extra weight.

QRPer:  Specifically, what ham gear did you take with you? Do you have a photo?

Blanchard:As noted in the book, I did carry a home-brewed 80/40 meter CW rig for the first 600 miles. For the rest of the hike I carried Steve Weber’s ATS-3A. The radio was powered by six Energizer disposable lithiums, in a home-brewed battery pack. The pack could also charge my cell phone and power the 2-meter VX-1R radio. I used a 51 foot random wire for the antenna and some counterpoise wire, usually about 15 feet. Altogether, the gear weighed around two pounds.

QRPer: If you were to do the hike again, would you take the same equipment?

Blanchard: I’m not certain I would carry the VX-1R again. I didn’t use it much and it is extra weight. However, the NOAA weather, and 2-meter capability could prove extremely useful in an emergency.

QRPer:What was it like coming back off the trail once you completed it? Any especially notable things about how you perceived the world around you? Did it change you? Any culture shock?

Blanchard: The only real “culture shock” was riding in automobiles. Everything seemed to move so quickly. I much more enjoy walking and biking now. I would be happy if I never had to drive again.

“KD2VX, Kathy, was the trail angel that helped out with my hike up in New Hampshire. She is a QRP fan.” (Photo: K1YPP)

QRPer: How many other hams did you meet on the AT who were either through-hiking the AT, or hiking sections?

Blanchard: Since we [hikers] don’t wear being a “ham” on our sleeve[s], I can’t really say how many hams I encountered. The few that I was aware of were mostly section hiking. One benefit of setting up my QRP station along the way was public visibility for ham radio. On a number of occasions I inspired my fellow hikers to look into ham radio when they returned home. I’ve even had a few readers of the book write me to tell me they went off and got a ham license based on inspiration from the book.

QRPer: If any other QRPers are inspired by your story, and are thinking about hiking the entire AT, how much money should they budget for such an adventure? Based on what I read, there are a number of budgetary considerations for shuttles, food, gear, and the like.

“Duncannon, PA was were I operated Field Day. The station table was a few rocks I moved around.” (Photo: K1YPP)

Blanchard: The answer to this question depends on how many “creature comforts” one wishes. Hiking as I did, with stops along the way about every 5-10 days, can cost about $1-$3 a mile. Those on a tight budget could do it for much less, and those that enjoy getting to hotels and eating in fancier places could spend more. Most of the shuttles were really not that expensive, at least those that cater specifically to hikers. The hostels are a real bargain, compared to standard hotels, but one may have to tolerate annoyances, such as snoring and people coming and going at unusual hours. If you’re a light sleeper, this could be an issue.

QRPer: On zero days [based on your descriptions] it seems like hikers simply stuff themselves with food. I’m really curious what you typically ate on the trail?

K1YPP’s 2008 Field Day “table” in Duncannon, PA (Click to enlarge, Photo: K1YPP)

Blanchard:The short answer is: I ate everything. I’m not fussy, and don’t have any diet limitations. If someone is diabetic, or vegetarian, it is still possible to undertake such a hike, it just might require more preparation. My typical day was a few Pop Tarts first thing in the morning, or hot oatmeal on cold days, followed by an on-trail mid-morning snack, such as a Snickers Bars or trail mix.

Lunch was usually something that didn’t need cooking. Roll-up tortillas, or bagels with peanut butter won out most of the time. In the colder weather, bagels and cream cheese was a favorite. Gatorade powder mix, or hot chocolate in cold weather, was my favorite drink for lunch.

The evening meal was usually a pasta-based affair, or couscous. I really preferred the couscous; it is very light to carry, needs very little energy to cook, and is loaded with nutrients. I would usually stir in some dried vegetables with it, or dried meat. As a side I would carry a dried sausage, such as pepperoni, which could also serve as a snack for lunch. I usually carried some desert items as well, such as cookies or dried fruit. Of course energy bars would supplement all of this along the way. Many hikers preferred candy bars, but I tried to avoid them in the warmer weather since they melt.

Overall, even though the diet sounds bland, it wasn’t bad. Of course, whenever we hit a town, I would stuff on everything in sight. I actually did eat well, but couldn’t find enough calories to maintain my weight. I ended up losing 35 pounds at the end of the hike and looked like a refugee.

Well, Dennis–all I can say is that I hope you’ve gained back some of those lost pounds, continue to be in good heart-health, and are able to enjoy a little QRP on your forthcoming hikes.  Thanks very much for taking the time to answer our questions; we wish you the very best!

Thoughts on the Elecraft KX1 and comparing with the Ten-Tec HB1B

My Elecraft KX1

I’ve been meaning to write a post about my Elecraft KX1, because, of all of the rigs I own, it’s the most-often-used, thus the clear favorite in my stable. But:  this morning, I read John Harper’s (AE5X) excellent assessment of the Elecraft KX1 vs. the Ten-Tec HB1B. He provides some significant numbers to consider when comparing these two lightweight CW-only QRP rigs, and makes a great case for elevating the newcomer HB1B over the KX1–at least, for some readers.

I’ve had my Elecraft KX1 for over three years, and, in all honesty, absolutely love it.  But, let’s face it: if I didn’t have one, if I had never touched nor used one, I would be seriously tempted by the HB1B–for its price, for the fact that Ten-Tec sells it (I’m a long-time Sevierville radio fan), and for the fact that it’s not a kit. Oh, yeah:  and because it works very well.

However, having used the KX1 for so long, I know that the HB1B (at least in its current state) could not replace my KX1. But before I explain why, I would like to make some strong points in favor of the HB1B.

YouKits HB1B Four Band QRP Transceiver
The Ten-Tec HB1B

The Ten-Tec HB1B

At least on paper, the HB1B has better filtering, a better display, and generally speaking, more bells and whistles than the KX1. Best of all, it comes fully assembled.

Why is this last point an advantage–? For a number of talented QRPers reading this, building the kit is the best part!  I know, I get it…And to tell the truth, I want to be like you kit-builders out there!  But I am only now getting into kit building, and building my confidence in kit-building.  I’m sure there are many others out there like me. For these QRPers, please note: the KX1 is not a beginner’s kit. I did not build mine. When I bought my KX1, I purchased it from a KX1 beta tester and professional engineer. The soldering and overall build quality are top-shelf.

Moreover, no matter how great an Elecraft radio is, it’s only as good as the person who built it. If the builder does sloppy work, your rig’s longevity and performance may suffer. Since you’ll likely be taking the KX1 with you everywhere, and it’ll experience a fair amount of movement (aka, hard knocks), this is especially important.

If, like me, you’re not prepared to take on building a KX1, fear not!–you should simply purchase from someone who knows their stuff: Elecraft can suggest some builders (including the amazing Don Wilhelm, W3FPR) or you can simply purchased a used KX1 fully-assembled. Or, you can simply purchase the fully-assembled HB1B.

So, why do I not find the HB1B enticing?

Yes, the Ten-Tec HB1B comes ready to roll. Still, could it replace my KX1?  I don’t think so. Two HB1B deal-breakers for me:

  1. As AE5X mentions, there is no internal antenna tuner option.
  2. There is no way (at least, on this version) to attach paddles directly to the rig.

Portability + Simplicity = QRP Fun

Why are these features so important? Well, my KX1 has an ATU, four bands, and an attachable paddle. One of my favorite things to do with my KX1 is, while traveling, to pull it out of its Pelican case, toss a 28′ wire into a tree, and lay a ground wire. As I stand there, I can hold the KX1, tune the antenna (easily 40M and up, with the internal ATU) and work stations my favorite way: while standing up.  I can also (if I like) sit for a moment, then jump up again, walk a bit, and generally move freely–just not possible with sit-on-a-table units.

My Elecraft KX1 fits nicely inside the Pelican 1060 case. There's even room to fit an external Whiterock paddle.

Additionally, everything I need fits inside a Pelican 1060 case. The Kx1 itself is an all-in-one unit–nothing external to attach, unless I want to. Oh, and I can also operate the KX1 with gloves on in below-zero conditions.

Anywhere QRP

Why would I want to operate standing up? Fact is, where I go, I’m only operating for thirty minutes or so, and in places where there’s no convenient spot to settle down or get too comfortable. In many cases, I’m operating on a whim–when I can grab a few minutes in a busy itinerary, or on a hike or day trip. With the Kx1, this is remarkably easy to do. I can have my KX1 on the air in four minutes or less, in most cases–and that includes the time to hang a wire–!  Packing up is also quick. This kind of operation feels as free as flying a kite.  Spontaneity at its best.

Part of that functional synergy comes from the fact that there are no additional components to hook up (i.e., no external tuner, external paddles). With the HB1B, I would be forced to either build a set-up, so that I could stand and hold the transceiver, tuner and paddles, or I’d have to…sit down.

Wayne’s inspiration for the KX1

Thinking back to a Dayton Hamvention several years ago, I seemed to remember that Wayne Burdick, N6KR (co-founder of Elecraft) was inspired by just this sort of off-the-cuff operation. To confirm this, I asked Wayne, just this morning, if I was on track with that. He offered this very thorough (and insightful) response:

I had been designing portable QRP gear for my own use for many years, including the “Safari 4″ (documented in three issues of QEX magazine in 1990). The Safari-4 was 3x5x7”, but it was fully self-contained, including an attached keyer paddle, internal 1-Ahr gel cell and manual antenna tuner, wattmeter, SWR bridge, and 4-band coverage. But it was too large for backpacking. Later, I designed some far smaller rigs with very good performance for NorCal and Wilderness Radio, including the SST, NC40A, and Sierra.

Then I started Elecraft with Eric, WA6HHQ. After we had success with the K2 and K1, I pitched the idea of a smaller version of the Safari-4 to Eric.

There were two inspirations for this. Back in the 70s, W7ZOI (Wes) created his “Mountaineer”, which was a crystal-controlled 40-m QRP rig that was very simple to use, very small, and self-contained, in that battery and paddles were built in. But it had no VFO, no ATU, a single band, and no frills. Taking what we’d learned in the K2 and K1 designs, I figured we could pack a great radio into this same size using updated technology. It had to cover at least 40 and 20 meters, and the idea was to use latching relays to minimize current drain and simplify band switching. We also used a DDS chip for the VFO–not quite as pure as crystal control, but just as stable, and totally adequate for a portable radio.

The other inspiration was my idea for an attached, but easily removable and mechanically reversible, keyer paddle. This became the KXPD1. I literally woke up at 5 AM with this idea. I realized immediately that this was the enabling technology for a hand-held radio, and I got busy with the design.

Having spent time camping and hiking with other rigs, I also knew that the ATU had to be built in. This allows the use of ad-hoc, wire-in-a-tree antennas, which is the secret to quick setup. It was a challenge creating an ATU that’s just 1 x 5″, but it worked. We spent weeks refining the rig and the ATU to work with typical field antennas, adjusting the component values to cover 40 and 20 meters. When we added the 30-m module, we found that it handled this well, too.

Most of my KX1 operation involves not even sitting down. I literally stop on the trail at a scenic overlook, pull the daypack around and extract the rig, toss a wire into one or two trees, and I’m on the air. I love this kind of operation. I’ve gone so far as to operate while sitting in a tree (an “inverted vertical”–a dangling wire–works amazingly well). Having to futz with add-ons can be fun, too, but it discourages “instant” operation. I like to quote Ade Weiss, W0RSP,  from his book The Joy of QRP: “If there is a place, and you can get to it, you must operate from there.”

You can’t overlook performance and features, either. The KX1 is stable in all operating environments and draws only about 35 mA. It includes a variable-passband crystal filter that can be widened out to copy AM and SSB signals, and can even do cross-mode (transmitting in CW while receiving LSB or USB). It has a full set of frequency memories and CW message buffers. For blind hams (or when you’re too tired to keep your eyes open), the KX1 has a 100% Morse-audio-feedback system. I tested this firmware with my eyes closed, and the result was very well-received by the blind amateur community.

Thanks for the history, and your inspiration, Wayne. Love it!

The KX1's Tuning, RF, AF and Filter knobs are very easy to operate--even with gloves on!

When you hold and operate the KX1, this legacy is all too apparent. Thoroughly thought through–down to a built-in LED lamp for logging–and, without a doubt, the original inspiration for several radios that followed: the HB1B, the MFJ 92XX series, and the Hendricks PFR3.

My guess is that the next generation of HB1B will have some of these clever features.

In the meantime, if you’re in the market for an inexpensive, CW-only, very portable QRP rig, and you’ve no plans to embark upon impromptu operation, the HB1B could be your rig. Based on my experience with Ten-Tec, if they sell it, they’ll give you excellent customer service. That is the beauty of these two choices, both Elecraft and Ten-Tec are excellent companies to do business with.

I only think I’d give up my KX1 for…the new KX3, and I’m not even convinced I’d do that, yet. The KX1 has become my little travel buddy. Time will tell, though. Check back here–if I’m wooed by another QRP radio, I may eat my words.

By the way, as I mentioned at the beginning of this post, the inspiration to finally write down my thoughts on the KX1 came from John Harper (AE5X) who has an excellent QRP blog that you should certainly add to your favorites!  And thanks, again, to Wayne, both for his response, and for his original ideas that continue to make QRP so liberating.

Photos and more details of the Elecraft KX3 from Dayton Hamvention

Don Wilhelm (W3FPR), everyone's favorite Elecrafter, holds one of the three KX3 prototypes.

Wow.

I got a chance to play with one of the two KX3 protoypes Elecraft had on display at the Dayton Hamvention.

I mean, wow!

Don (W3FPR) gave me a  tour of this amazing rig. It’s small,  feature-packed and as ergonomic as all of the machines that come out of Aptos. It is slightly larger than the KX1 in every dimension. Still very easy to hold (as you can see in the photo to the right). Not pictured are the mini CW paddles (not based on the current KX1–much better) and a small attachable microphone. I’ll try to photo them tomorrow and post.

I spoke with Elecraft owner/founder Wayne Burdick (N6KR) at length as well.  He said that the KX3 has been in the works for years. It’s built on the ideas of Elecraft and many of its owners, he said they’ve simply been waiting for technology to catch-up with their vision.

I actually think this could be a major game changer in the ham radio world. Think about it…a portable transceiver with the receive capabilities of the world-class K3, all band, general coverage, firmware upgradable, with many options including a full-fledged automatic antenna tuner, 100 Watt amp and many optional modules.  Did I mention it’s ultra portable? Gosh!

Oh yeah, Wayne told me it will be sold for under $800.

I must have one.

Over half of the 2N2/XX transceiver kits have been sold. You’ll recall (see previous post) that these kits were first offered at Pacificon and have been sold online since then. If you are interested in building one of these kits, you should not wait to make a purchase. Go to NorCal’s website for details.

UPDATE — 12/01/2008

Please read the update below from Doug Hendricks:

Due to problems with the stability of the VFO in the 2N2 kits, we hav suspended shipping until the problem is resolved and we can figure out which parts to put in the remaining kits, and which parts to send out to those we have already shipped. Please bear with us. We will get it right. Also, please, please, please do not send us emails asking where your order is. Every order is safe, and will be filled, we just need time to take care of the problem that we found. Emails to me won’t help, nor will an email to James or Kathy or Dean or Jim K. Thank you for your understanding. 72, Doug, KI6DS

UPDATE – 12/16/08

Hendricks has started shipments again and fixed the VFO problem.  Read message posted to QRP-l below:

Finally there is some good news to report!!  James tells me that shipping
has resumed on the 2N2xx kits for those that were held up while Jim Kortge
solved the problems in the VFO.  Jim did a tremendous amount of work and
we now have the parts to fix the problem.  The kits we are shipping now
have the correct parts in them, and those parts are being mailed to all
who previously purchased the kits.  Please, please do not email and ask us
where your kit is or when it will be shipped.  We are shipping as fast as
possible, and hope to have all kits shipped before the 1st of the year
that have been ordered.  (Don’t you just love my sentence structure??  My
English teacher is rolling over in her grave.)

We will be accepting new orders sometime in January and it will be
announced here.  James, Kathy, Jim K., Dean and Ron are working like crazy
to get your kit to you.  Thank you for your patience and understanding.
