Operating Notes: DX @WA2HOM, 4/25/13

The Ann Arbor Hands-On Museum is open Thursday evenings, but from September though April I bowl on Thursday nights, so never get to take advantage of that.  We’ve finished for the year now, though, so yesterday, I walked down to the museum and put WA2HOM on the air for a couple of hours.

One of my first contacts was with Marco, IZ8LJZ. The contact itself was the standard DX contact, i.e. short and kind of boring, but when I looked him up on QRZ.Com, I found this photo below. What a lovely spot!

Marco, IZ8LJZ lives in Praiano, on the beautiful Amalfi Coast.

20m was open to Europe, so I made several more DX contacts before I left for the day. One of them was with Tom, G3HGE. We were both 599, and we had a not-so-normal DX contact, chatting for nearly 30 minutes.

Tom’s QRZ page said that he used to be a manufacturer of amateur radio gear, so earlier today, I Googled him. As it turns out, Tom was the man behind TW Electronics, a manufacturer of VHF gear from 1958 – 2000. There’s a nice history of the company on the TW website.

Now in his 80s, Tom now makes paddles and bugs. I don’t know if he’d like this comparison, but you might call him the “English Begali.” His latest creation, the TW Olympic shown below is a dual-lever bug that uses magnetic tension. He was using this bug for our QSO, and it sounded great. I’m already thinking that maybe I could get the XYL to put that on my Christmas list.

The TW Olympic is a two-lever "bug" that uses magnetic tension and has a speed range of 14 - 28 wpm.

On the air this weekend at WA2HOM

WA2HOM is our club station at the Ann Arbor Hands-On Museum. I go down there nearly every weekend and operate for anywhere from two to eight hours. This weekend, I had a lot of fun down there.

This photo, from the Boy Scouts of America website, shows one Cub Scout sending code to another.

Late last week, I was contacted by a woman who was a Cub Scout pack leader, asking if she could bring some Scouts by. Silly question. Of course, she could! We arranged to meet around 1:45 on Saturday. Well, right on time, she arrived with three Cub Scouts in tow.

Fortunately, I had just made contact with Jim, K0JIM, and he had a really solid signal here in Ann Arbor. That’s important because it’s sometimes difficult for inexperienced operators to hear a weak signal or one that’s accompanied by a lot of noise. When signals are weak or hard to copy for any reason, the kids get frustrated.

We were doubly fortunate in that Jim was just great with the kids. He asked each their name and got them to tell him a little bit about themselves. And, none of the kids were mike-shy, so it was a good experience for everyone involved. In addition to having them talk on the air, I took them over to our Morse Code display and showed them how to send their names in Morse Code.

I really hadn’t planned to go down on Sunday, but after doing some things around the house, I decided to zip down there about 2:30 pm to check into the Rotarians on Amateur Radio net. It’s so much easier to do from down at the museum because of the beam antenna. I didn’t hear a peep on the net frequency (14287 kHz) at either 3 pm or 4 pm (2000Z, which is the time listed on the ROAR website), though, so I’m not sure what’s going on there.

When I’m at the museum, I’m usually also tweeting. (I’m @kb6nu on Twitter.) I tweeted that 20m sounded kind of quiet, and got a reply from @hamradioireland, EI2KC, suggesting that we give it a try. After agreeing on a frequency, I pointed the beam northeast and gave him a call. Unfortunately, the propagation didn’t cooperate, and we could barely hear one another. Even so, it was still pretty cool using Twitter to arrange a DX QSO.

Tuning around after my short QSO with EI2KC, I found a couple of interesting nets. The first was the Collins Collectors Association Net on 14263 kHz. I could really only hear the net control station, but it sounded as though everyone checking in was running some kind of Collins gear. It was interesting to listen to, but not being a Collins operator, I didn’t check in.

Around 4 pm, I started looking for the ROAR net again. I never did find that net, but I did find the Heathkit Net on 14293 kHz. According to the Web page Heathkit Resources, the net starts at 2030Z, but I’m guessing that it really started at 1930Z.

Since I have a bunch of Heathkits—several that I still use regularly—I did check into this net. They’re a great group of guys, and I will definitely be checking into this net again. Who knows? It may even spur me to get my HW-101 back on the air.

More on getting kids into amateur radio

My recent post, “Another take on getting kids into amateur radio,” garnered nearly a dozen comments, so there certainly seems to be a fair amount of interest in the topic. Coincidentally, I recently came across two items on the Internet on this topic:

  1. WS4FSM @ the South Florida Science MuseumAmateur Radio at the South Florida Science Museum. This effort is very similar to our station, WA2HOM, at the Ann Arbor Hands-On Museum. They’re exposing kids to amateur radio, with a view towards getting them interested in the hobby. Unfortunately, they’re having trouble raising funds. I e-mailed Tom, AJ4XM, about how we were fortunate to get grants from the IEEE and the ARRL and have encouraged him to try as well. In the meantime, he’s trying to raise funds by getting hams to donate on the Net. If you have a few bucks, you might consider donating something.
  2. International Electronic and Ham Radio Camp 2012 in the Czech Republic. This article appears on the IARU Region 1 website. It describes a very cool camp conducted by a group of Czech hams. The ten-day camp drew a group of 40 kids from Austria, the Czech Republic, and Slovakia. Activities included kit-building, contesting, and a number of field trips. Anyone know of something like this being held here in the U.S.?

Beam fixed!

A week and a half ago, my friend, Bob, WD8BNA, came  up to me at our Rotary Club meeting and said, “Have you taken a look at your beam lately?” referring to the three-element Yagi at WA2HOM, our club station down at the Ann Arbor Hands-On Museum.

“No,” I replied, “what’s up?”

“Part of the antenna’s missing,” he said. “It must have come off during the high winds we had last week.” I drove by the next day, and sure enough, we were missing half the reflector.

Jack, WT8N, who was majorly responsible for us getting the beam up in the air in the first place, jumped right on this. He got up onto the roof, found the missing element, and organized a work party to re-attach it.

The work party was this afternoon. Jack; Ovide, K8EV; yours truly; and Jerry, head of maintenance for the museum and the son of a ham headed up to the roof to lower the antenna and fix the antenna.

Lowering the antenna proved easier than I expected. We unbolted the tilt-over tower from the mounting bracket and it came down relatively easily. Re-attaching the errant element was also pretty straightforward. All the bolts were there. It looks like we just didn’t tighten it down well enough the first time.

Tilting the tower back up proved to be a little more difficult. We first tried it with two men pushing and two men pulling on one of the guy wires.  When that didn’t work, we tried three guys pushing it, and one pulling. That didn’t work either.

Ovide then went in search of another helper. He returned shortly thereafter with one young museum employee, and with four guys pushing, we finally got the tower into an upright position. We inserted and tightened the bolts, and now we’re back in business with all of the elements in the right position. Overall, this took just an hour to do.

Despite missing half of the reflector, the beam seemed to work just fine. It tuned up just fine, and was still quite directional. I’m sure with the complete reflector, it works even better, though. If I knew more about antenna modeling, I’d run a simulation and figure out how much directionality we were actually using.

Has anyone done this? If you have, or have some idea what the effect of losing half of a reflector has on a three-element Yagi, I’d like to hear from you.

WA2HOM: Championship Contest Station?

In the mail today, I received something totally unexpected—a certificate proclaiming WA2HOM to be the first place finisher in the multi-operator, single-transmitter category of the 2011 CQ World Wide WPX contest.

CQ WPX Certificate

With such a low score, I don’t supposed that we had many competitors in that category, but it’s still pretty cool.

A special (event) day at WA2HOM

I had a special day at WA2HOM today…a special event day, that is.

First of all, it was SKYWARN Recognition Day today. There were more than 100 National Weather Service amateur radio stations on the air today (see map below).

SKYWARN Stations

More than 100 NWS amateur radio stations were on the air today for SKYWARN Recognition Day.

I managed to work eight of them including stations in FL, IL, KS, KY, MA, TN, TX, and VA.

I also contacted several stations participating in the Southeastern Conference (SEC) Amateur Radio Clubs Special Event. This operating event was held in conjunction with the SEC championship football game. I was able to work three of the stations: AA4UT (Univ. of Tennessee), W4DFU‘ (Univ. of Florida), and W5YM (University of Arkansas). It was great to hear so many college club stations on the air.

One thing that I found a little curious is that the event lasted only from 8:00 am to 1:00 pm.  Then, it hit me. The game must have started at 1:00 pm. D’oh!

I worked two stations commemorating the attack on Pearl Harbor. The first, N4WIS, was aboard the battleship U.S.S. Wisconsin in Norfolk, VA. The second, W2W, was located at the National Electronics Museum in Baltimore, MD.

When I wasn’t busy working the special event stations, I managed to sneak in a couple of DX contacts. The first, VP2MOR, was on the island of Monserrat. The second, NH7U, is on the island of Molokai in Hawaii. It was kind of neat to work NH7U as I’ve actually been to Molokai.

In addition to all these great contacts, I was able to give a couple of demos to interested museum patrons. That rounded off a really special day down at WA2HOM.

JOTA gets scouts on the air

At the Ann Arbor Hands-On Museum Saturday, we participated in the 54th Jamboree on the Air (JOTA). As the website says, “The Jamboree-on-the-Air, or JOTA, is an annual Scouting event that uses amateur radio to link Scouts around the world, around the nation, and in your own community.”

We didn’t have a big turnout, but we had a lot of fun. The hams that turned out included Pat, W8LNO; Quentin, KD8IPF; and Mark, W8MP. Pat and Quentin are both involved in the Scout leadersip; Mark’s 14-year-old son, Brian, KD8EEH, is an Eagle Scout. In addition to Brian, we had four Cub Scouts, whose names I didn’t write down (sorry!), and via 2m FM, Stuart, KD8LWR.

They all were able to talk to other Scouts, all on 20m phone.

The highlight of our operation was our QSO with XE1L in Mexico City. XE1L is the station of Luis, a friend of W8MP. This was not a scheduled contact at all. We just happened to run across them.

Brian, KD8EEH, made the contact, and spoke in Spanish with the two Mexican Scouts, Stephanie and Alex, for more than 45 minutes. I was certainly impressed with Brian’s Spanish skills. I don’t think that I could have kept up the conversation so long.

In addition to the HF station, I set up our 2m radio and connected to several EchoLink nodes at which hams were participating in the JOTA. One of them was in California, the other in Ontario. Stuart talked to several of the Scouts in Canada.

Next year, we might think about being a bit more organized. That might make the experience a little more educational for the Scouts, but just getting them on the air was a lot of fun.

T32C in the log at WA2HOM

I didn’t make many contacts today down at WA2HOM, but I had a great time.

First off, I had planned to put PL-259s on the feedlines for the dipole and the VHF antenna, but when I went to do so, I found that it had already been done! That was very cool.

Next, I hooked up the Icom IC-V8000 to see what repeaters we could hit. First, I tried keying up the ARROW repeater. Nothing. Hmmmmm, I thought, maybe it’s just down. Next, I tried the U-M repeater, which is less than a mile away as the crow flies. I was able to key it, but the S-meter showed only a couple of S units. Something was wrong.

I swapped feedlines, and voila! Everything worked as I’d hoped. Somehow, we’d mis-labelled the feedlines. Not only that, there’s still nothing connected to the end of the dipole feedline, so I was actually able to key up the U-M repeater without an antenna!

Anyway, after connecting the right feedline to the radio, I chatted a bit with both Ralph, AA8RK, and Pat, W8LNO. Talking to Pat was fortuitous because he’s involved with Scouting, and when I mentioned that we planned to operate the Jamboree on the Air next weekend, he volunteered to come down and help out. That means we will be able to operate two radios, the HF station on 20m and the VHF station through the U-M repeater to EchoLink.

T32C DXpeditionAfter that conversation, I turned the HF rig back on, and thought I’d see what was on 15 m. Tuning around, I found a small pileup on 21.017. I called up DXWatch and determined that the pileup was for T32C, the DXpedition to Chrismas Island. I accessed their record on QRZ.Com, found the bearing, swung the beam around to 260 degrees, and heard them quite well. After setting the transmit incremental tuning to about 2 kHz, I worked them on the second call! I just love that beam!

A Downsized Field Day

It seems like everyone (except for maybe Google) is downsizing these days. With that in mind, I thought that I’d downsize my Field Day. Instead of participating in the large 5A ARROW Field Day operation, the guys that hang around WA2HOM, our club station at the Hands-On Museum, decided to set up a much smaller operation.

Our first idea was to set up outside the museum. That seemed like it was going to work out until Quentin, KD8IPF, informed me that he couldn’t attend, as his wife was going to be out of town, and he needed to take care of his kids. I was concerned that without Quentin that we wouldn’t have enough operators to have two people there at all times.

Then, Quentin volunteered his backyard. This turned out to be a great venue. He has a fairly large, with a couple of big trees. Not only that, he lives next door to his mother-in-law, and she’s volunteered her trees as antenna supports. You gotta love a mother-in-law like that!

One of the advantages of downsizing is that you don’t have to spend so much time setting up. Instead of setting up antennas for five HF stations, a GOTA station, and a VHF/UHF station, all we had to do was set up antennas for our two HF stations. And, since we planned on using Quentin’s already-installed, multi-band dipole, we only really had one antenna to worry about.

That being the case, we decided that we really didn’t need to start setting up until noon on Saturday. Jim, K8ELR, and I actually arrived about 11:30 am, and that proved to be more than enough time. Jim brought with him a 40m dipole and a 30m, end-fed half-wave antenna, while I brought my BuddiStick. We quickly decided to put up the 40m dipole, and by 1pm, we were already on the air.

A Tale of Two Antennas
Of course, it wasn’t really as simple as all that. When we started operating, the two stations interfered with one another something terrible. So much so that my KX-1 was even causing Quentin’s LDG autotuner to retune itself when I transmitted.

The problem was that the 40m dipole and the multi-band dipole were running nearly parallel to one another. I should have known that this would occur, having been involved with more than a few Field Days by now, but it never even crossed my mind.

Fortunately, the solution was relatively simple. All we had to do was to take down the multi-band dipole and hang it from two different trees, one of them in the adjoining yard. After we did this, the two antennas were nearly perpendicular to one another, and the interference just went away. The phone station could not hear my little peanut whistle signal at all, and while I could hear the phone station transmit, it really didn’t affect my ability to make contacts.

I really didn’t think that this was going to work, but Ovide, K8EV, was quite confident that it would. I was the one that ate crow.

Did You Really Use a KX-1?
So, I can hear a lot of you asking, “Did you really use a KX-1 for Field Day?” Yes, I did. Our original idea was to run all QRP. The thinking behind this is that if you run all QRP, then you get 5 points for each QSO.

The other reason for doing this is so that we could run off batteries. Quentin had access to two, 66 Ahr batteries, and we’d planned to use these two batteries as our power source. I figured that with the 12V gel cell that I have for my KX-1, that would be plenty of power.

Unfortunately, that didn’t work out. Quentin and Ovide were just not having any luck making any contact at 5W—and consequently not having much fun—so they decided to increase power. That blew our QRP multiplier, but what the heck, it multiplied our fun factor.

Plenty of Power
As it turned out, just one battery provided plenty of power for the phone station, even at 100W. Granted the station was off the air from about midnight Saturday through 9 am Sunday morning, but there was apparently plenty of juice to power that station throughout the entire 24 hours.

Likewise, my little gel cell provided enough power for the KX-1 over the 12 hours that I had it on the air, and I’d guess that the charge would have been good for the entire 24 hours. I have yet to run down that battery so low that it failed to power the radio.

What Did We Learn?
We learned several things from this Field Day:

  1. A downsized Field Day can be as much or more fun than a full-blown operation. Without a big crowd vying for just a few positions, everyone got a chance to operate. Plus, setup and teardown times were a lot shorter.
  2. You still have to pay attention to your antennas. If we’d done a little more planning and thinking about our antennas, we would have avoided the interference we experienced and possibly even been able to run QRP on phone.
    How, you might ask? Well, if I’d thought about rigging up some kind of wire beam or a Moxon beam for the phone station, they may have been able to run QRP and still make contacts. This is certainly something to think about for next year.
  3. The batteries worked great. Not only did they provide enough power for a 100W rig for more than 12  hours, they were quiet. The noise of a gas-powered generator can really get on your nerves over the course of a Field Day.
  4. While I probably wouldn’t want to run the KX-1 in a big DX contest, it worked pretty well for Field Day. I made more than 160 QSOs with it in about 12 hours of contesting.

So, What About Next Year?
Since it’s never too early to plan for next year’s Field Day, we’re already kicking around a few ideas:

  1. Find a campground to have Field Day at next year. The upside is that the scenery might be nicer. The downside is that we might not have the nice antenna supports, errrr trees, that Quentin has in his backyard.
  2. Be more competitive. Joe, N8OY, came by late Saturday evening, and racked up a bunch of points for us on 20m CW. He suggested that we organize some of the local hot-shot CW operators around here and set up a real competitive operation. The upside is that scoring a lot of points is fun. The downside is that being competitive excludes the less-experienced operators.

One thing is for sure. Running a smaller Field Day event in no way diminishes it as the “quintessential” amateur radio event. We still enjoyed all the camaraderie as well as all the technical aspects of  Field Day. Now, I can’t wait until next year.

WA2HOM: Adding Countries to the Log

I’m usually not one to work the big contests, but there are some advantages to participating, even if you don’t have a lot of time or plan to submit a log. One of the advantages is that there are a lot of countries on, and you can add to total of countries that  you’ve worked.

This weekend was the CQ WPX  CW contest. I only operated for about three hours, the bands were kind of lousy on Saturday, and I only worked 15 meters, but even so, I managed to add eight countries to the WA2HOM log. They include:

  • HK1R – Colombia
  • SZ1A – Greece
  • 6W/RK4FF – Senegal
  • HQ9R – Honduras
  • EF8M – Canary Islands
  • J7A – Dominica
  • J39BS – Grenada
  • HC2SL – Ecuador

It’s nothing real exotic, but new ones nonetheless.
