KB6NU's Ham Radio Blog

I was talking to Kurt KC8ULG just now and we got to talking about antique radios. He has a small collection, including a Korean war vintage receiver and a Hallicrafters HT-32 transmitter. He’s also just purchased a regenerative receiver kit, which is not strictly an antique, but the design certainly is. I have a few vintage radios myself, including a couple of Hallicrafters receivers and a 1940s Philco.

Since our monthly club meeting was just yesterday, that got me thinking that having an antique radio “show and tell” might make a good program for an upcoming meeting. I know there are others who also have some cool old radios they could show off.

Kurt also mentioned that he has an old Dumont Oscillograph, one of the first oscilloscopes. That got me to thinking about yet another topic for a meeting–how to use an oscilloscope.

Do you have any suggestions for up coming meetings? If so, please comment below. Thanks!

I participated in the FISTS Winter Sprint yesterday, which ran from 1700Z to 2100Z. While I have taken part in other contests, I’ve never done it seriously. During last year’s Field Day, I worked a little CW for our club, and during the 2002 CW Sweepstakes I got on and handed out a few QSOs, but in neither case did I submit logs.

So, this was my first contest as a serious competitor.

1700Z is noon here, so I got on a little earlier to make a few QSOs and warm up. The last of these contacts ended about 1650Z, and I tuned up to 14058 to wait patiently. The anticipation was actually kind of exciting. Time seemed to slow down as I watch the clock: 1652, 1653, 1656, 1658, 1700!

As soon as the first station started calling CQ FISTS, all the others jumped in. My first contact was with K5TPC on 14057. I then camped out a little on 14057.5 and had some success there, working four or five stations in very short order.

Then, the activity slowed down a little and I decided to go searching for other stations calling CQ. I think, in retrospect, that that was a mistake. I should have perhaps tried to keep my position on 14057.5, calling CQ, but I think that I’d have eventually been forced off the frequency by the higher power stations.

I spent the entire first hour, scanning between 14057 and 14060, totalling about 15 contacts. Then I went through a real dry spell. Tuning around a little, I found that the contest had spread down as low as 14050, so I set up down there and began calling CQ. I had some success, but the bulk of the stations were still up around 14058.

For the next three hours, I split my time between 14057 – 14060 and 14050-14055. When one went quiet, I’d tune over to the other. For a while, I tried calling CQ FISTs down around 14051, but didn’t have all that much success.

The third hour was the worst. I think I only made six or seven contacts from 1900Z to 2000Z. I was thinking about calling it quits, but then I figured that since I’d stuck it out this long, I might as well finish.

I’m glad I did. Activity seemed to pick up the last hour, and I not only picked up more contacts, but more multipliers as well. In the last 15 minutes alone, I made six contacts, including three multipliers (WI, TN, and LA).

All in all, I think I did pretty well for my first “real” contest. I had a total of 43 contacts, yielding 212 QSO points (one of the contacts was not a FISTS member). With the 25 multipliers, my score was 5,300. 20m was pretty much open all over, except to the west coast, which accounts for the high number of multipliers.

For most of the contest, I had the keyer cranked up to 20 wpm. That seemed to work just fine for most contacts. A couple of times, I had to slow down, but since the format was pretty cut and dry, most all the ops could go at least 20 wpm.

I also made use of the memory function of the keyer, programming in “CQ FISTS DE KB6NU.” It did save a little wear and tear, but working a paddle really isn’t all that much work. I probably should have also programmed in “UR 599 MI DAN 9342,” which is the standard QSO, but it wasn’t so bad sending that.

To sum up, I learned something about contesting, and even more importantly, had a lot of fun. I’m definitely going to seek out more contests, so that by the time the 2003 Field Day rolls around I’ll have that much more experience to bring to the party.

Last Sunday, the 20m band was in odd shape. I could only hear a few domestic stations, but quite a few DX stations. The problem was that while I could hear them, my signal was just not strong enough to work them.

This is partly due, of course, to my antenna installation. I am currently using a ground plane antenna made from antenna wire, supported at the top by a handy tree branch. The antenna is about 15 feet behind the house, but past that, the ground slopes upward, effectively shielding radiation in that direction. Believe me, if I’d been more active in ham radio when I was looking for a new house, I’d never have bought this place.

At any rate, this frustrating turn of events got me to thinking about how I can upgrade my antenna farm. I suppose I could go whole hog and put up a 50′ tower and a full-size beam, but that’s quite costly and I doubt I’d make many friends with the neighbors.

Another idea is to put up a small tower on the roof and on top of that install a compact beam. Glenn Martin Engineering makes a couple of roof-top towers that are reasonably priced. Their eight-foot model is about $240, and since the house is already 25 feet high or more, the antenna would be 35 feet above ground.

As for the antenna, I did a little Web searching and found several manufacturers of compact beams, including:

• Mosley Electronics, makers of the TA-33jr,
• TGM Communications, which makes a whole line of compact beams, and
• Hex-Beam. The HexBeam is an unusual design. The elements are full size, but folded to require less space., which

The more I think about it, though, I think a quad antenna might be a better choice. They’re usually ligher and smaller. Here are a few that I found on the Net:

• Cubex Skymaster
• Gem Quad
• Antenna Mart

I also think I could build my own rather than buying one. That would not only make it cheaper, but it would be fun, too. Hams on eHam have recommended the following as good sources of information for building your own:

• The book, Cubical Quad Antennas : How to Build and Adjust Quads by William I. Orr, Stuart D. Cowan. Unfortunately, this book is now out of print.
• The article, Update on the Pfeifer Quad System, appeared in the September 2001 QST.

The ARRL website also has a number of other articles on the topic.

In a way, I’m kind of geeked about doing this. Despite my protestations earlier, that I’m not an antenna genius (and I’m still not, believe me), I have gotten several to work here. It’s also a lot of fun to build them and get them to work.

It’s gotten to the point where I’ve worked just most of the active FISTS members on 20m. That’s OK with me, but while I’m not that big on awards, I would like to get my FISTS Century Club award. I think I’m close to 75 points now, but at the rate I’m going, it will take me another six months to get there.

I suppose that what I really need to do is to put up another antenna so that I can work 40m or 80m.

I’m also going to give the Winter Sprint a go on Saturday, Feb. 8. It runs from 12 noon to 4 pm EST. I should rack up a few points then.

Friday evening, Mark W8FSA and I gave a demonstration of amateur radio to a group of Boy Scouts and their parents. I’d like to say that everything went perfectly, but of course it didn’t. Even so, I’d like to think that we did some good on Friday.

I carted my IC735 transceiver and power supply down to Lincoln High School, which was hosting the Boy Scouts. Mark brought his G5RV antenna. That worked out well enough, except that there was no place to really hang the antenna. Lincoln is a rather new high school, and none of the trees were very high.

About the only thing that we could do was string the antenna between two vans, but of course that meant that the antenna was only six feet off the ground. At that height, 20m was the only band that the antenna was usable on, and at 9:30 pm, the band was pretty dead. We weren’t able to make a single contact.

We were, however, able to show the kids the equipment and answer a bunch of questions. Also, just before I left for the high school, I found a new ARRL brochure aimed at kids. I downloaded it from the Web and printed a dozen copies. We distributed these, and the kids seemed very interested in them.

The fathers were also quite interested. Several of them took the brochures–on which I jotted down the URL of our website–and seemed interested in getting their licenses and attending our classes. We, of course, invited them to attend our meetings.

I think that we could and should do more of this kind of public outreach. Perhaps, giving a lecture to public service groups, such as the Kiwanis or Lions Clubs would be in order. The word is that the ARRL is coming out with a CD-ROM presentation that would be appropriate for showing at such meetings.

We also need to work on our demo station. It should be something that goes together quickly and can work in a number of different conditions. My transceiver would work just fine, but we need to come up with a more portable, multi-band antenna to accompany it.

Maybe this is something I can get our Technical Coordinator and Public Service Officer to work on. Hmmmmmm. :)

Over the last couple of days, I worked two stations whose calls would be more appropriate for me, given my line of work:

VE1WEB
N4URL

Other calls that might be kind of cool for a web developer:

K8PHP
W8SQL
KJ8AVA
etc.

Of the 100 or so 20m CW contacts I’ve made since the beginning of the year, only one of them has been with a woman. And even that one’s questionable. The name I was given is “Toni,” and while that’s generally a nickname for Antonia, I can’t really be sure that Toni is a woman.

Here’s a breakdown:

• 8 instances: Bill, Jim
• 5 instances: Dick
• 4 instances: Bob, John
• 3 instances: Bruce, Dan, Dave, Doug, Larry
• 2 instances: Dennis, Don, George, Phil, Tony
• 1 instance: Alain, Bud, Card, Conrad, Ed, Earl, Ernie, Evan, Fred, Fritz, Gene, Glen, Gordon, Greg, Hector, Jason, Jeff, Jerry, Jiggs, Joe, Jon, Karl, Ken, Lee, Mal, Marcel, Mark, Maurice, Mike, Norm, Orin, Orv, Ralph, Rich, Rick, Rob, Ron, Roger, Roy, Skip, Ted, Toni, Tripp

Admittedly, this wasn’t a scientific study, but one thing I’m surprised about is that there were only four Johns in this poll. Another odd factoid: Dennis only appears in this list because I worked both of them today, one right after the other.

Seriously, though, where are the women?

I didn’t intend on participating in the North American CW QSO Party this afternoon, but I got sucked into it anyway. Silvia and I had gone out to the grocery store and got back just a little bit before 3 pm. I sat down at the rig, intending to make a few QSOs, and was a little astounded when I heard all the activity. Then, I remembered that today was the contest.

I’m not much of a contester, but I thought I’d listen for a while and see what was going on. I listened to a few QSOs and it seemed simple enough. All the ops were doing was exchanging names and locations, so after about 15 minutes I decided to jump in.

I responded to the first station I heard call CQ NA, and he came right back. Just like on Field Day, I was hooked.

After about five or six contacts, I decided I needed more speed, so I cranked up the keyer to 20 words per minute. Since I wasn’t calling CQ myself, only responding to CQs, all I really had to send was first my call, and then once the other station came back to me, “TU DAN MI”. Even I can send that at 20 wpm.

Also as on Field Day, I often had to listen to a station give his information more than once before I could log it. Towards the end of my two hours, though, I was getting good enough at it, that I only occasionally had to listen to a station twice to get the info.

All in all, I made 40 contacts over the course of two hours. Not a great feat, but it was fun, and good practice for Field Day. If I keep working at it, I may just be ready to crank out some points this June.

Today, I worked two hams operating CW from their cars. The first one lived in the Houston area; I worked him in the morning on his way to work. The second mobile CW station was in Virginia. He was on his way to pick up his wife from work in the afternoon.

The amazing thing about this–or one of them anyway–is that they made fewer keying mistakes than I did, even though they were driving around while I was just sitting on my butt.

Phil, near Dallas wrote me about his setup. He says,

“I drive a Ford Taurus 96 Model. It has a center console between the two front seats, so I built a combination table and rig support out of particle board so it could be slipped in and out as required. I drilled four holes in the rig holding board for the feet of the rig to set down into and then I used a web strap with quick release snaps to hold the rig in place. I put a 1/2-inch thick piece of foam rubber (the same kind of rubber which hobby shops sell for surrounding gas tanks for the R/C powered model aircraft) between the rig and the board surface. This way, the road shock does not effect the rig. I used the same mounting technique for the key.

“The mobile station is comprised of a fully loaded Elecraft K2 with power from the car. The key paddle is a bencher black and chrome model and the antenna is a trunk lip mounted 20 meter or 40 meter Hamstick.

“I keep a note pad handy and only take down the call, and name. The rest of the information is in my head as I am copying code in my head also. It took me several months to get used to not writing everything down. Now, I am running between 20 and 23 wpm copying code in my head and remembering most.

“I do not carry a log with me and only record the results of the days conversation after arriving to work or home. A lots of times stations will tell me we have worked before, but without the log everything is pretty much a blur.

“Since most of my driving is freeway style driving, I simply key the rig with my free right hand. I have about an hour commute each way every day to work. I obtained my FISTS Century Award Certificate, Fists QRP Award Certificate and Fists Mobile Award Certificate all the same time by working FISTS stations QRP mobile only. My FISTS No. is 9352 and my CC No. is 1325.

“Currently I have over 225 FISTS contacts toward my next award. I have worked all but 7 states using the QRP Mobile set-up and over 25 different countries. My best DX, longest distance of over 8,000 miles with 5 watts, and the most interesting QSO was with an Australian VK7 station.”
