What is it about low power operators that binds us together? I’ve been reflecting on that a bit lately.

As a student of anthropology and culture, I see a bit of a tribal influence among the amateur radio ops of the world. We tend to cluster into tribes based upon our modes of operation and other specialized pursuits like contesting, fox hunting, award seekers, etc. Each tribe has its own special characteristics, culture, jargon and social structure.

What I enjoy most about the QRP tribe is that the Elmer spirit is still very much alive and well. Although we all are a bit competitive and like to think we have a line on the best way to do QRP, there is a healthy amount of sharing of information, expertise and even hardware. Groups like Adventure Radio Society, NAQCC, Flying Pigs, Polar Bears, AZ Scorpions, NE QRP, North Georgia, 4 States, etc breed healthy competition and provide us with sources of information and expert assistance when needed. I sure am enjoying getting to know, both on air and in person, some of the people that make these groups work.

My recent connection with Diz W8DIZ while operating the FOBB, prompted me to go back and read the history of the Flying Pigs and to read through the archives of the Bacon Bits Newsletter. There is real gold and a wealth of interesting info that’s been recorded and made available freely. Other clubs have the same heritage. I say a BIG THANK YOU to all the QRP groups for sharing their experience and stories. It makes me feel proud to be part of the tribe!

What about you? What do you enjoy about QRP? Leave a comment and share your thoughts and story.

Various QRP related email reflectors and lists are full of chatter about the Flight Of the BumbleBees (FOBB). Comments about the CW being too fast and the weather being too hot at this time of year make it sound like a broken event. IMHO it is far from being broken! It is probably the premier QRP event of the year. And I say, if it ain’t broke… yep, you guessed it, don’t fix it.

Sunday the bands were full of QRP ops, both home based and portable, so the activity really did make a BUZZ despite band conditions that have not been all that helpful to hf qrp contacts.  The weather was HOT, but hey, find some shade, altitude or water and go for it. Historically this is the time of year for this event and as others have commented, it keeps our activity up during the summer time when vacations and mowing the grass take their toll on ham radio activity.

As far as fast cw, I’m not fast (not even close hi hi), but it sure is fun listening to the buzz on the bands rather than QRN and a high noise level with only a few weak signals. Certainly I am not a hard core contester. My cw skills are still in need of practice, but isn’t that what events like this provide? I often have to listen multiple times to get the callsign and info but that repetition and practice pushes my speed and confidence level up every time I try. After listening to a fast op several times I have the info I need and then I jump in and have fun making a contact at speeds faster than my comfort zone. Most of us slow guys can send faster than we can receive, right? Come on in, the water is fine, and FUN!

My XYL, Connie and I drove over to Honeymoon Island State Park on the Gulf Coast in Dunedin, Florida. This is a very pretty beach, not overly crowded most of the time and has been one of the top rated beaches in the US for several years. The weather cooperated, there was no sign of the BP oil spill that has run so many tourists to other locations, and we snagged a primo spot to operate right next to the water.The only negative, if you call it that, was that the view was sometimes distracting, but sure was enjoyable.

K4UPG Honeymoon Island FOBB Site July 2010

My trusty Sierra and Buddistick provided plenty of action so I never switched over to my mini-bac Delta Loop backup antenna. I also stuck to 20m the whole contest since 40m has been in such poor condition here in Florida lately.

One of the great things about these events is the leveling of the playing field. It is fun to contact the guys that write the articles, create the websites and design the equipment that we use for our hobby. My score was modest at 26 QSO’s, 18 Bumblebees and 17 states and provinces but it was one fantastic day of activity for me! Being able to connect with the big guns of QRP was a thrill too!

For me, one of the highlights was when W8DIZ rode over to meet me as I was setting up my site. Diz lives about 3.5 miles from Honeymoon island and is a regular bicycle visitor of this great beach location. I’ve been a customer of his toroid and kit business and have benefited from the info he has shared, not to mention being one of the movers and shakers of the Famous Flying Pigs QRP group. Diz I was honored that you took time out from a busy family day to swing by and say HI! Thanks for the help getting our screen house up too!

Thanks to Adventure Radio Society and the guys that put this event on for all of us. We appreciate the effort it takes and you deserve the very best of 73′s from all of us.

Welcome to Handiham World:
A volunteer summer continues as Larry Huggins, KA0LSG, makes the cover of Worldradio

Larry Huggins, KA0LSG, is right there on the cover of the latest Worldradio magazine. Way to go, Larry!

The photo is from Handiham Radio Camp, where Larry volunteered as an instructor. In the Worldradio article, you can read about the blind-accessible HT that Larry demonstrated to our Operating Skills group. The article is my annual accessible radio roundup, a quick overview of radios and their accessibility features. It is entitled “What’s New for the Operator With Disabilities”, and is a feature of my regular “With the Handihams” column.

“Regular readers know that from time to time I devote a column to what’s new in amateur radio equipment and software that is accessible to people with disabilities. Most of the questions I get have to do with what is blind-accessible, both for radio hardware and computing. Our largest single accessible technology user group is amateur radio operators who have some kind of reading disability, usually blindness or some degree of vision loss. I think this is probably a long-term trend as more baby boomers encounter age-related deterioration of their eyesight. Macular degeneration is relatively common in older folks and because of its onset late in life can catch them off guard and leave them wondering if they can still use a computer or even get on the air effectively anymore.”

There are always questions about accessible handheld radios, so this part of the article is timely:

“Handiham volunteers Larry Huggins, KA0LSG, and Ken Silberman, KB3LLA, both found the new Wouxun 2m/70cm KG-UVD1P HT at Dayton, and Larry actually had his radio along to demonstrate to us at Handiham Radio Camp.”

Our thanks to CQ Publications for helping us get the word out about accessible technology.

One of my favorite QRP groups is the 4 States QRP Group that sponsors Ozarkcon. Today we had an interesting thread going on their email list concerning slingshot antenna launcher and visibility of the line and sinker.

I’ve been working on that issue for a bit and offered my current solution. Still not 100% perfected, but it is working well now. Here in Florida, the tallest trees are mostly pines and the bark is pretty sticky with sap and lots of crooks and crannies that don’t allow monofilament fishing line to slide as freely as I’d like. I’ve tried the archery reel and slick braided line and although it does slide nicely through the trees, it is much slower and challenging to reel in and also is very prone to tangles and wind knotting which wastes time to untangle. In low wind or super sticky pine trees it is still the best solution.

Below are some photos of my cheapo solution to the slingshot line launcher. A $4 slingshot from Harbor Freight and a 99 cent shelf bracket from Lowe’s are the basic components. One challenge is being able to see where the sinker and line end up after the shot. I tried painting the sinkers, but in tall grass or lots of leafy trees, it did not show up as easily as I would like. The simple solution I found was to use fluorescent plastic surveyor’s tape (also from Lowe’s) to add both vivid color and some motion to help me locate the sinker whether in the trees, air or ground. I’ve also recently switched to red colored monofilament line called Cajun Red Lightning that offers a bit more visibility than clear monofilament.

Here are the basic elements… slingshot, Shelf bracket, spincast reel

If you are looking for an inexpensive simple solution, this might be the answer! Give it a try and let us know how it works for you. Leave a comment or better yet, join the 4 States QRP Group and join the conversation.

A volunteer summer

Eliot, KE0N, gets the remote base project underway

Eliot, KE0N, at the new remote base control point.

The Handiham Remote Base at Courage North has proven to be reasonably reliable and quite popular with the Handiham membership. Just in case you need a refresher, our Camp Courage North location is in far northern Minnesota near the headwaters of the Mississippi River. The station is at the location where we held many Handiham Radio Camp sessions over the past two decades. It consists of a Kenwood TS-480SAT, a rig control interface and computer, an LDG auto tuner, and a G5RV antenna. The station runs W4MQ software to control the radio and SKYPE to port the audio both to and from the remote control operator. Users sign in with their approved credentials and are able to control the radio, changing the frequency and other parameters, and use the radio for both transmit and receive functions. The idea is to provide a real radio for many of our members who cannot otherwise get on the air because of antenna restrictions or other impediments to installing an HF station. Some of our members who do have their own stations also appreciate being able to operate from a completely different location. In addition to the W4MQ software interface, up to five users without transmit privileges can listen to the radio by connecting to W0EQO-L on Echolink. If no transmit control operator is present, Echolink users may control the radio’s receive frequency using the text box feature of Echolink, simply by sending a frequency in the text and pressing enter. This feature is useful for a quick check of propagation conditions here in the Midwest. For example, a user might enter the number 10 to hear what The National Bureau of Standards station WWV sounds like here in Minnesota.

Since only one transmit control operator can run the station at a time, there is a need for a second remote base. That is why we are pleased to have the able assistance of Eliot, KE0N, and Lyle, K0LR, who are working together to help me with this second Handiham remote base. Our new callsign will be the traditional Handiham headquarters call of W0ZSW. We hope to have the station in operation by the end of July, and when Eliot visited Handiham headquarters yesterday to work on the project, he made a lot of progress. In case you were wondering, the radio we have chosen is a Kenwood TS-570S. This radio, which has the capability of operating 160 through 6 m, will be coupled through an MFJ autotuner to a W0OXB 300 foot “special” wire antenna at an average height of 45 feet. This arrangement will allow us to offer 160 m through 6 m capability from the new remote base location. The existing remote base station at Courage North operates only 80-10 m using a 102 foot wire antenna, so we think that this will be a significant addition to our member services. The rig control computer is a Windows machine configured and supplied by KE0N, and the interface is a RIGblaster Pro. The radio is equipped with the VS3 speech module for blind users.

Lyle, K0LR, engineer for the Courage North station, is helping us with the station configuration. Our goal is to copy all of the user credentials from the first remote base to the new remote base so that users will have easy access to either station. This will also help us with tech support issues, and as you might guess we hope to keep those at a minimum!

One advantage of having two remote base stations separated by a significant distance is that there will be more choice for operating when conditions are bad in one spot but not in another. In the event that one station goes down, the other one would still be available. Redundancy is a good thing if you want to keep a service like this up and running.

No project worth its salt ever gets through the installation process without a few glitches and a visit from our associate engineer “Murphy”. Sure enough, Murphy’s presence was felt when the necessary DB9 serial cable turned out to be missing in action. We still have some issues to figure out with port forwarding and a static IP address, for those of you who understand what that stuff means. Nonetheless, we are pleased with the progress to date and feel that we are on target to have this member service available very soon.

Handiham Headquarters spruced up

The Handiham headquarters entrance in the Camp Courage Reception Center.

You have seen photos of our headquarters before, but things are looking pretty good now at the Cyril Rotter Technology Center. Antennas rise to the left of the round building, and the 300 foot wire antenna is invisible high up in the trees to the left. The double doors can open wide to accommodate electric scooters or wheelchair users.

QSL cards

Since it is strictly “slow news” for ham radio this time of year, how about telling us about some favorite QSL cards you have either sent or received over the years? A photo or scan would be helpful, if you have one.

This photo shows a Handiham 25th anniversary sticker that we produced in 1992. The idea was to stick these onto your existing QSL cards and send them out to help promote the Courage Handiham System. They are pretty rare, so if you have a card with one of these Silver Jubilee stickers, hang onto it!

So what do you have? Send it to [email protected] with your comments.

Hello, Pat.

Could you please remind our readers and listeners that we need people to take part in the Handiham nets, both the daily net and the Wednesday evening net. Summer is a particularly slow time and we need more participants. Remember that these nets are open to everyone and that you do not need to be a Handiham member. So bring a friend and join us — you may even find the Handiham net a place to make new friends!

Had a good day in the park with Jim K4AHO and Wally KG4LAL. Spent a good bit of time testing a couple tuners for End Fed Half Wave antennas using Jim’s AIM 4170. Wow is that thing a great tool for tweaking antennas! Info overload!

I built an antenna tuner based on AA5TB’s design for an end fed half wave antenna. I am using a 3 ft or so counterpoise on the ground as Steve suggests. On the analyzer in a test lashup it was a bit touchy to hand capacitance but tuned well even up to 21Mhz. Since I am not thinking of backpack size I used a pretty good sized enclosure for it. I am using an air variable 6-160pf cap instead of a polyvaricon like Steve used since space is not a big issue. I also used a T68-6 toroid instead of the T50-2 Steve used.

When I mounted it in a plastic box the sensitivity seemed to increase. I have not put a LED SWR bridge in the box yet, as I was waiting to see how it worked before adding more variables. Today I was able to put an AIM 4170 analyzer on it and it did tune the antenna… seems that the air variable I used is perhaps a tad small. It is almost fully meshed on 40m cw and on 20m it acts like even at minimum capacitance the sweet spot is very narrow and hard to tune.

Here's the innards

My question(s) are:
1) Is the hand/body capacitance normal? If not, what might cause it to
be so touchy?
2) Would my parts layout be part of the issue?
3) Does the DPDT switch (mini toggle) I added for later use with the SWR
bridge add significant capacitance to the circuit? I was able to match a
21Mhz load on the raw test setup, but not once it is in the box.
4) I have a small bus wire for a ground, do I need to increase that?
5) Is the plastic box the problem? Would it be better in a metal enclosure?
6) Am I asking too many questions? Sorry, this is how I learn. Build,
test, ask…

SWR bridge I want to use

Thanks for your wisdom and experience on this one.
