Owensboro ARC reaches out to younger audience. The Owensboro Amateur Radio Club  hosts a children’s program at the Owensboro Museum of Science and History where kids can learn the Phonetic Alphabet while making crafts. “We are trying to get younger folks interested,” Walt Shipman, KI4OYH, said Thursday. “It’s where it starts.”

I like this idea! It might be something we can do down at the Ann Arbor Hands-On Museum….Dan

Lighthouse to go international. Radio operators from around the world will be including the Oak Orchard Lighthouse (NY) in International Lighthouse Lightship Weekend, Aug. 17 and 18. It is the first time the lighthouse is participating in the event fully.

Keeping an eye on the sky. If you go to the Lancaster County (NE) Super Fair, you’ll probably see guys in golf carts and green jackets offering rides to those in need. Those guys are members of the Lincoln Amateur Radio Club. Members of the club are also trained storm spotters — many involved in the Nebraska Emergency Management Agency, and they know exactly what to do if severe weather hits.

 

Operating notes: public service, helping people have fun with amateur radio

Bicycle TourThis past weekend was a big weekend here at KB6NU. On Saturday, I and more than a dozen of my ham radio brethren provided communications for the Ann Arbor Bicycle Touring Society’s One Helluva Ride. There were close to 2,000 riders, and our efforts helped keeped the ride running smoothly.

Of course, it helped that the weather was just perfect. It was sunny and the high temperature for the day was in the low 80s. That helped keep the number of flat tires and exhausted riders to a minimum.

Even so, kudos to Jeff, W8SGZ, the ARROW organizer for the event. He did a great job of organizing the event.

An old friend on the repeater
Yesterday, while walking down to the museum,  I happened to catch an old friend, Chuck, K8HBI, on the ARROW repeater. I hadn’t heard Chuck on the air for quite a while, and I didn’t recognize him at first, partly because he’d changed callsigns. K8HBI used to be his father’s callsign. Chuck was K9HBI.

I don’t know if his father has passed or just let his license expire (although I suspect the former), but Chuck now has his dad’s callsign. Since I talked with him last, Chuck has retired, and now has more time for amateur radio. I was happy to offer my assistance in getting him back on the air.

As we were talking, Chuck happened to mention that his daughter had gotten a tattoo with both callsigns in honor of her father and grandfather. I suggested to Chuck that now his daughter should get her license and then the K9HBI callsign.

New friends
At the museum, I met what I hope will be a new friend – eleven year-old Alex. His mother had e-mailed me, saying that her son had expressed some interest in amateur radio and could they come down to the museum to see our station. Of course, I replied!

Alex and his mother stayed for over an hour. He asked me to make a CW contact, and he seemed at least somewhat interested in learning the code. We also made a phone contact, and he had fun chatting with Bob, N2AF, in New Jersey.

As they were about to leave, his mother leaned over and said to me, “Thanks so much. He rarely sits still for so long. He really must be interested in amateur radio.”

On the way home, I met another new friend on the ARROW repeater. After giving out a call, Fred, WA8LJL, came back to me. Fred’s not a newbie, but he said that he has been off the air for a while. He just purchased a new handheld and was in the process of programming its channels when he heard my call. I was his first contact in many years.

All of this was very enjoyable for me. While I certainly do enjoy the technology, I enjoy helping other people get into the hobby and get more out of the hobby even more.

Putting up another antenna

When I got home from the Ann Arbor Hands-On Museum on Saturday, I called up my friend Mark, W8MP. I wanted to tell him about my contact with OG3077F, a Finn who has successfully worked all 3,077 U.S. counties. As it turned out, Mark has worked him several times. I should have suspected this. Mark seems to know everyone.

As we continued our conversation, he mentioned that one of his son’s friends had put up an antenna and that they were going over there to help him tune it up that afternoon, and he asked if I’d like to join them. Mark’s son, Brian, is KD8EEH, and his friend, Alec, is KD8RGP. To be honest, I was a little hesitant. I was kind of tired after walking home from the museum, but Mark twisted my arm a little, so I agreed to head over there.

On the phone, Mark suggested that I might want to bring over some coax and some other kinds of antenna-making stuff, so that if we needed to make modifications, we’d have the wherewithal to do it. So, I loaded my crate of antenna parts, my toolbox, my 100-ft. tape measure, and a spool of coax into my Mini.

When I got there, I found that Alec was way ahead of us. He actually had already set up a 20m dipole. One end was suspended from an old, now unused power pole at the back of Alec’s backyard. The other was suspended by a rope draped over a downspout.

The construction was actually quite ingenious. For the center insulator, Alec had drilled some holes in a small block of wood that provided both strain relief for the wires and a way to mount an SO-239 connector. I wish I’d taken a picture of it. The end insulators were made from some scrap plastic.

Ingenious though it was, I suggested that we might wan to rebuild the antenna with an HQ-1 center insulator (right) to make it more reliable. While we were at it, I also suggested that we use a set of HQ-2 insulators for the ends. Mark got the boys working on disassembling the current antenna and rebuilding it with the new insulators, and in a short time, it was back up in the air.

Because Alec had already routed the coax down to the basement, we all tromped down there to see how well it tuned. Yipes! It looked to be way long. So, we lowered it, shortened each side by six inches and tromped back down stairs. We were closer this time, but it still needed to be shorter, especially since we were tuning this for the phone portion of the band. We shortened it by another six inches, and bingo, this time we got a nice dip right around 14.25 MHz.

Flush with success, someone suggested that we might want to add 40m elements to the dipole. This sounded like a good idea to me, and I told them about the 30m/40m dipole that I have. After a little discussion about whether to use feet or meters to calculate antenna length (we decided on inches as my tape measure is ruled in feet and inches), Alec started scrounging around for some wire.

At first this looked like it was going to be a problem. There was one 28-ft. length, and a couple of other odd lengths, but it wasn’t clear that we were going to be able to make two, 33.5-ft. lengths from the pieces we had. We finally did figure it out, though, and the antenna was lowered, and Alec attached these elements to the center insulator.

As it turned out, there were some convenient supports for these elements that allowed this dipole to be oriented nearly perpendicular to the 20m dipole. On one end, the boys used a tree, and at the other end, the wire was draped over another a downspout on the opposite side of the house.

We again tromped downstairs to check the resonance. Again, we were quite long. We lowered the antenna and shortened it by six inches on each end, then measured again. This time, the resonant point was just below 7 MHz. This time, we shortened the antenna by nine inches on each side, and the resonant point was just about in the middle of the General Class portion of the 40m phone band.

Of course, the proof of the pudding is in the eating, so we told Alec to get on the radio and see if we could make any contacts. Tuning around, Alec found a few stations working the Missouri QSO Party. He called a couple of them, and worked them on the first call.

At that, we called our efforts a success, and went upstairs to eat some take-out curry that Alec’s parents had gotten for us. Over dinner, we all patted ourselves on the back. I’m sure that Alec is in for a lot of fun on 20m and 40m.

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.

Minutes of the January 2013 ARRL Board Meeting

ARRLThe annual meeting of the ARRL Board of Directors was held January 18-19, 2013 in New Orleans, and the minutes of the meeting were recently published. You can download and read the entire minutes yourself, but here are a few items that I found particular interesting:

  • #16. Mr. Kramer presented the report of the Chief Operating Officer. Finding appropriate ways to support the growth and activities of ARRL-affiliated clubs was an issue highlighted during discussion of the report. As chairman of the Programs and Services Committee, Mr. Norris advised the Board that the committee has established a subcommittee to address the issue.
  • #21. Mr. Carlson, as chairman, presented the report of the EMC Committee and entertained questions. There was a discussion of how to stimulate electric utilities to resolve cases of power line interference to amateur stations.
  • #25. The board adopted seven legislative objectives for the 113th Congress. To read them all, download the minutes, but in addition to the usual items such as, keeping and defending our frequencies, #6 aims at ensuring that two-way radio communications be exempt from distracted driver laws, and #7 supports legislation authorizing the FCC to appoint an electrical engineer to their staffs to provide technical expertise.
  • #28. The ARRL has created “the ARRL Amateur Radio Service to Scouting Award, to be administered consistent with the Community Organization Award program of BSA.”
  • #32 The board will appoint an ad hoc committee to look into the recent Logbook of the World problems and provide some recommendations at the July 2013 meeting.
  • #37. Lucy Ann Lance, a local broadcaster here in Ann Arbor, MI was awarded the “Bill Leonard, W2SKE, Professional Media Award, developed to honor professional journalists whose outstanding work best reflects the enjoyment, importance and public service value of the Amateur Radio Service.”

As I was club president here in Ann Arbor for several years, and for several years served as the Michigan Section Affiliated Club Coordinator, I’m especially interested in #16. I’ve e-mailed my director and vice-director to get their takes on it, and I would encourage all of you to do likewise for any of the items that are of interest to you.

Amateur Radio in the News: Michigan, Kansas, Colorado

Central Middle School radio club students work on projects
The future of amateur radio in Midland was in room 127 of Central Middle School on Wednesday afternoon.Bill Albe brought kits to build the FET crystal radios he designed, along with tools sure to excite middle schoolers — drills, solder, means to measure electrical resistance across their bodies — plus ample adult supervision.

I’m trying to find out more about this project so that I can do something similar at the Hands-On Museum….Dan

Back to the Future — amateur radio enthusiasts bring transmitter back to life
The wait – four weeks short term and 40 years and counting long term – was well worth it when the 75-year-old transmitter built by amateur radio pioneer Marshall Ensor was reactivated Saturday evening at Ensor Park and Museum south of Olathe.

Ham radio alive and well in Boulder County
This is a nice profile of the Boulder Amateur Radio Club (BARC). BARC Juniors is a program of the club, which encourages kids to get involved in amateur radio. Great club, great program.

Operating Notes – 11/1/12

ICOM/Kenwood Power ConnectorJunk, continued. A couple of months ago, I wrote about the importance of junk in amateur radio. Well, here’s another example.
Last week, my friend, Ralph, AA8RK, acquired a used TS-850. Unfortunately, it didn’t have a power cable, so he sent a message to our club e-mail list asking if anyone had a cable he could buy from them. It struck me that while I didn’t have a cable that I wanted to sell him, I did have all the parts needed to make one. For some reason a year or so ago, I happened to purchase the Molex connector at a hamfest, and at Dayton this year, I purchased more 12-ga., two-conductor wire and a big bag of PowerPole connectors.
Ralph came over Monday night, and we had a fine time making the connector and talking about ham radio in general. Ham radio is more fun if you have the right junk!

Horse-fence antenna revisited. One of the things that Ralph and I talked about was my horse-fence antenna. I was unsuccessful with my first attempt at making a 2m dipole with the horse-fence material and just haven’t had the motivation to get back to working on it. Well, when I showed it to Ralph, he said, “It looks to me like you have a bunch of little capacitors there,” referring to the 14 very fine stainless steel wires running through the plastic ribbon, “maybe that’s detuning it.”
I think he might be right.  I’m going to go get a couple more clamps and clamp the far end of the antenna elements and see what effect that has.

55th JOTAJamboree on the Air (JOTA) 2012. Almost two weeks ago now, we had a great Jamboree on the Air at WA2HOM. On Saturday, we had eight or ten Scouts. Several of them already had their General Class licenses, so all I had to do was sit them down at the radio, show them how to use the controls, and they were off to the races. They even worked a new country for us – Trinidad. The cool thing was that the station they contacted down there was also participating in the JOTA, and they got to talk to some Trinidadian Scouts.

 Sandy quiets the bands. On Tuesday night, the 40m band was oddly quiet as hurricane Sandy took out the power on the East Coast and otherwise occupied hams there. It was quite noticeable that there were a lot fewer stations on the air.
