QRPxpedition with a damselfly for an op?

Posted in General Operating, Parks on the Air, Portable operations with tags , , , , , , on 2011/07/27 by Pete Spotts

'Let's see, is this the dah paddle or the dit paddle?' I offered to serve as control operator and let the damselfly have a go at a QSO, but it politely declined in favor of taking a tour of a new portable paddle I was breaking in.

I was born and raised in southern California, where folks justifiably bragged about being able to hit the beaches in the morning and the mountains in the afternoon. Of course, they meant afternoon of the next day, given LA’s traffic. But I that’s another story.

Folks here in the Bay State can come close to making the same statement, with some adjustments for traffic. Today’s QRPxpedition to activate Halibut Point State Park for the first time for Parks on the Air (POTA) highlights the briney end of that beach-to-mountain itinerary.

The oceanfront park, just north of Rockport, Mass., occupies a site that once served as a granite quarry, the quarry pit now a deep pond in the center of the 54-acre reserve. The park is joined at the hip to another 17 acres of state reservation. Wandering through the small Visitors Center prior to setting up my station, I was intrigued to learn that the point’s original name was Haul About Point — a moniker sailors pinned on the granite prominence in the heyday of sail. How it got from Haul About to Halibut? A “name that homonym” contest, maybe?

For World War 2 buffs, the site hosts a fire-control tower that was used to support coastal artillery.

The park's Visitors Center made good use of the artillery fire-control tower used during World War 2. The tower not only affords great views of the park. The New Hampshire coastline to the north is easy to track on a clear day.

I arrived at the park at about 11:00 a.m. with the nagging feeling that the coffee I drank on the way was demanding freedom.

Just my luck. The two, small, gender-specific restrooms in the Visitors Center had been commandeered by an untold — but from my desperate vantage point, significant —  fraction of 55 elderly women who had traveled from the Boston suburb of Newton on a chartered bus to take in the park.

What’s a guy to do but stand, chivalrously, legs tightly squeezed, until the last woman leaves the room marked Men? “Why, thank you, young man.” That’s how you know they are elderly — when they tag as  ”young” a man into his third 20-year tour and sporting a silver (or so my wife says) beard.

Relief, then station set-up, came at last: The increasingly familiar orange Jackite pole for antenna, if not moral, support. The FT-817ND, tuner, key, keyer, and paddles (yep, I switch back and forth between straight key and paddles).

I know I’m hardly the first to observe this, but each outing seems to add a bit of refinement to one’s operations.

A couple of for-instances:

For instance 1: I’m a big fan of the FT-817ND. But as it sits on a table as delivered, gets peg legs to lift the front (slightly), or rests on a riser made from a discarded CD case, its display is still tough to see.

So I said to myself: “Self,” says I, “Why not set it on top of the battery case you put together for the 7.2 amp-hour battery that powers this get-away special?”

“But it slides around up there,” I replied. (Note: The sign of senility is not when you talk to yourself; it’s when you talk to yourself and reply.)

“Well, how about using some nylon straps?” came the reply. A quick trip to the hardware store netted a pair of eight-foot straps, which I installed around the battery-radio stack, then trimmed to manageable lengths. And, so, we have this:

QRP stackers

For instance 2: I recently picked up a new set of mini paddles to go with my “mint” keyer. The damselfly at the top of the page is sitting on the new paddles. Now, the paddles have a slick feature — a base into which the paddles slide. Mount that base onto the Altoids-tin keyer, and you get this:

N0SA's TIP-1 mini paddle with its base mounted on my portable-station electronic keyer.

Which becomes this:

The TIP-1 mounted on the keyer -- and at a better height for working the paddles. Part of the inspiration for this came from a photo I'd seen of a Rock Mite QRP rig, built and modified by Bob Leach, AF2Q, with what looked like an American Morse Equipment Porta Paddle affixed to the top.

The paddles are now at a better height for my hands, the keyer buttons are right at hand, and the paddle can be removed and stowed separately — and carefully — when it comes time to stuff the station back into my lumbar pack. Works for me.

As for the contacts? Five, count ‘em, five, in three hours and 10 minutes. The bands were awful. With the same set-up, I had bagged six contacts in the first hour of operation at the Blue Hills State Reservation on Monday, and with time to spare for chats with visitors. Today, one could run up and down the bands and hear virtually no one.

That’s not necessarily a bad thing, if you have all day. I didn’t. My wife needed the car by time certain.  I had to factor the two-plus-hour drive home into my operating plans. Thank heavens for K4ZLE, who answered my CQ just as I was about to pack up for the day. He was contact No. 5, the final one needed to qualify the park for POTA.

For the record, the hale and hearty few who answered the calls today include:

N4EX — North Carolina — 20 meters (Rich is another POTA ham)

K0ZK — Maine — 20 meters

W4MPS — North Carolina — 20 meters (We exchanged howdies when I was on Mt. Holyoke last week)

N4DSP — North Carolina — 20 meters (a fellow user of Xlog, logging software for Linux)

K4ZLE — Ohio — 20 meters (who capped the day as a success)

Yeah, there’s definitely a Midwest/North Carolina thing going on here. Now, where’s my barbecue??

CORRECTION: In the original post, I misidentified the bug in the top photo. I have been informed that the attractive bug is a damselfly. My apologies to both dragonflies and damselflies in the hope that neither was insulted. And thanks to KD5ONS for pointing out the difference.

QRPxpedition to the heart of an ancient volcano

Posted in General Operating, Parks on the Air, Portable operations with tags , , , , , , on 2011/07/26 by Pete Spotts

My operating site near the summit of Great Blue Hill, south of Boston. The city's skyline is just visible on the horizon.

Somewhere between the easy chair and 14,000+ feet lie those “sweet spots” where amateur radio operators who are not mountain goats, but love the outdoors, can blend their interests in both. Add Great Blue Hill to your list of those sites.

I did, and by the end of the day July 25, the reservation would qualify as Parks on the Air (POTA) USMA005.

Great Blue Hill is the geographic anchor to the 7,000-acre Blue Hills State Reservation south of Boston. Seen from a Boston skyscraper, the hill stands tall on the southern horizon.

One can only imagine what it looked like 440 million years ago. More precisely, what its volcano looked like. Great Blue Hill and its six smaller, adjacent neighbors are the exposed portions of a vast magma chamber that once fed the volcano. The ancient mountain exploded, collapsed to form a caldera, the magma in the magma chamber crystalized, then slowly the caldera eroded to bare a bit of its long-cooled, hardened heart.

Home to the oldest continuously operating weather observatory in the US, today’s summit is a short, comfortable hike along one of several trails or up a paved road. Just below the summit, a large stone shelter and its 35-foot observation tower provided the destination for my outing to activate the reservation for Parks on the Air.

Eliot Tower, built during the Great Depression by the Civilian Conservation Corps.

Given the heat wave much of the country, including New England, had been experiencing over the preceding week, the weather was perfect for a day-long QRPxpedition. The temperature rose no higher than 73, with the clouds contributing to the cooler temperatures. And foot traffic was the order of the day, which made for great conversation, and a surprise, end-of-day  ”eyeball” QSO with a local ham I’d contacted earlier in the day.

QRPxpedition to a gorgeous Mt. Holyoke park

Posted in General Operating, Parks on the Air, Portable operations, Public Service on 2011/07/20 by Pete Spotts

A view of the Connecticut River Valley from near my operating position on Mt. Holyoke, within J.A. Skinner State Park in central Massachusetts. The river is barely visible along the tree line. This is why QRP was invented!

Parks on the Air is back in business in Massachusetts, thanks to some great weather (if the low 90s is great) and some wonderful spots to operate from.

This time, the destination for my outing was A.J. Skinner State Park, at the west end of the tiny Holyoke Range in Central Massachusetts. The park is about a two-hour drive from Franklin, MA, where I live. With plenty of picnic areas on the summit, along with trees for antenna support (thank you for pointing that out, Google Earth), Skinner looked like a good spot to chip away at some of my vacation time outside the confines of Camp Idohwanna (our home).

So, at 6:00 a.m. EDT on July 19, I dropped my wife off at the commuter-rail station in Franklin for her trip in to work, topped off the car’s fuel tank, topped off my internal tank at a local Dunkin’ Donuts drive-through, and hit the interstate for the trip to Mt. Holyoke.

Munchkin Morse-code key – how munchkin?

Posted in Miscellaneous, Portable operations, Projects, QRP with tags , , , , , , , on 2011/07/11 by Pete Spotts

American Morse Equipment's MS2 mini key and a, er, larger companion.

So how small is American Morse Equipment’s new MS2 mini key? It’s about that small…

With apologies to readers of the previous post, who may have been left wondering about the scale of things.

Munchkin Morse-code key for portable radio ops

Posted in Miscellaneous, Portable operations, Projects, QRP with tags , , , , , , on 2011/07/11 by Pete Spotts

American Morse Equipment's new MS2 mini key, where pounding brass becomes tapping aluminum.

American Morse Equipment’s new munchkin Morse code key, the MS2, was unveiled earlier this year at the national hamvention in Dayton, Ohio, and once the announcement hit the QRP email lists, I couldn’t wait to see what Doug  Hauff — the company’s designer, engineer, machinist, and all around inventive guy — had come up with.

As even a casual visit to my Morse-code key collection page can attest, I’m a sucker for the small. And with two other items from Doug’s collection of key and paddle kits in use at my home station and with my portable gear, snagging one of his new keys was a no-brainer.

Doug’s “web dude” gave the MS2 its own description and order page July 2, so I quickly put in for one and received the MS2 key kit within three days of my order (caution — the USPS isn’t fastidious about updating their tracking information).

When the padded envelope arrived, I hustled it into my basement shop, unpacked the parts, and got ready to put the key together. But, gasp, instructions had yet to be posted on Doug’s web site.

The parts are  few, however. And having assembled his KK1, I figured I didn’t have to wait for his “web dude” to get his page-update act together. So, with band conditions a bit wiggy during this weekend’s Straight Key Century Club Weekend Sprintathon, I took time out to assemble the key.

As of 22:38 UTC July 11, the instructions still are MIA on Doug’s pages. [Update: Instructions were posted on the AME site at 11:39 UTC on July 12.] So herewith a description of how I assembled the key, along with a crude list of parts (I don’t have a gauge for determining screw sizes).

Morse code keyer in a really mint enclosure

Posted in Miscellaneous, Portable operations, Projects with tags , , , , , , on 2011/07/04 by Pete Spotts

A look under the hood at K1EL's K12 keyer kit in a hip-pack-friendly enclosure -- the ever popular Altoids tin!

With the Flight of the Bumble Bees coming up, as well as other summer opportunities for taking ham radio on the trail, I was looking for a keyer to accompany either of my two QRP radios — an Elecraft KX1 and Yaseu’s FT-817ND.

Yes, they have built-in keyers. But you have to wander through menus to make changes. And I find myself partial to K1EL’s K12 keyer, which I built last February and put into an industrial strength case for use at home.

This year’s Field Day and the limited space in the fanny pack that carries my portable station inspired me to try for a smaller, lighter version of the keyer. So off went another order to K1EL, and off I went to the local drug store for some Altoids, with their curiously useful tins.
