POLL RESULTS SO FAR: West Virginia is in the lead for best Ham Radio QTH in the USA… One more week of voting… Have you voted yet? Here’s the link to vote!
Last weekend I played in the QRP Afield event and had fun with fellow Polar Bear QRP Club members on the air. It was a great time. Once again, the antenna tweak won out and under the influence of a great blog post by Polar Bear #20 VA3SIE, Martin in Ontario about the 88ft Doublet, I caved in and put one together the night before the event. Oops, I did it again! But this time I had excellent results and the antenna worked as advertised. LESSON: Sometimes it pays to follow your heart and not your head.

I also remembered how I learned a lot as a young teen aged ham via the Civil Defense program. Remember that time?
Watching a weather report about tornadoes reminded me of a great learning experience. The Palm Sunday Tornadoes of 1965 hit the counties north and east of my home in Elwood, IN. At only 15 yrs old, I was the assistant emergency coordinator and ran the 6 meter emergency communications net on Sundays. Our county and city Civil Defense teams had setup equipment and were ready for disasters and those tornadoes reeked havoc on our area.
Path of the Palm Sunday Tornadoes
Our teams rolled out the emergency vans, and the adults helped this young ham handle traffic for the state police and other government emergency responders. The old yellow CD Gonset Goonie Bird rig is still something I remember fondly. I loved running that thing!
LESSON: Give the young hams some responsibility and empower them. They will be there when the time comes and will never forget how older folks treated them as peers and gave them an opportunity to do something important. I bet that kind of opportunity will still attract young people to our great hobby. We need them! They need us!
The Yellow Goonie Bird
As a bypass survivor, each morning when possible, I go for a brisk walk. We are blessed to live in a nice development in Orlando which has a bit of lakefront and also has some irrigation and flood prevention ponds. This water attracts a good selection of wildlife which makes it fun to be outside and exercising even though the heat and humidity are often both above the 90 mark.
We have ducks, baby ducks, coots, turtles, snakes, eagles, hawks, osprey, sand hill cranes, storks, cormorant, anhinga, raccoon, possum, squirrels, armadillos, feral cats, foxes, geckos, lizards, frogs, toads and all sorts of other neat critters to entertain us at various times of the year. This morning I spent some time watching the water birds fishing on all the new fingerlings from this year’s hatch of bass, bream and tillapia that gather in the grass along the water’s edge.
Learning S & P from a Heron
Today a heron demonstrated how to do catch fish and I realized that the heron could teach me some things about operating QRP style search and pounce.
The heron has a particular style… they spread their wings like this great photo demonstrates so well (thanks Chris Harshaw and http://www.wikimedia.org). So what’s that got to do with ham radio? Like a karate master who learns from the world around him, a good QRP op can learn from the birds! The heron shades the target with its wings to take the glare off the water so it can see better. It also causes the fish to become confused and they can pick off the loner or easiest target.
Same thing with QRP… we need to spread our wings by tuning around a bit more agressively and listening for the ones we can snag. Not always the strongest, but a signal that is decent and an op that genuinely wants to make a contact. When we find that contact we need to pounce on it and not waste time.
Yes, I learned a bit from watching that heron this morning. He caught quite a few fish in a short time using his form of search and pounce. That heron was quick and moved from spot to spot gingerly and didn’t miss his target very often. No wonder he’s grown so large! I want to be more like that heron when I am on the air.
Still time to cast your vote in the poll for the best ham radio location in the USA.

Spent my birthday participating (casually) in the Straight Key Century Club Weekend Sprint. My Lake Fredrica neighborhood site was where I set up my shelter and 3 antennas. I had a 40m dipole fed with twinlead up 40 ft and running E-W. An End Fed Halfwave for 20m was nearly vertical suspended by a nearby tree. A twinlead 44 ft doublet on my 20 ft Jackite with the ends at 16 feet was setup running N-S to give me a bit of a mini-smorgasbord of antenna choices. Since it was really sunny, I hooked up my ACME GC100 Solar Charger and VW Solar Panel.
Bands were decent with 40m quiet and some DX coming through early from Eu stations. Nice to hear that again. 20m came alive and was pretty much the go to band for the majority of the day. I did check 15m a couple times but did not hear much and no one replied to my CQ’s.
In the middle of a QSO, my Jackite pole decided to collapse but I was able to finish the QSO with one end of the dipole about 4 feet above the ground. hi hi
The highlight of the day was my last QSO with EA3NO, Lluis in Spain. As the special station for the sprint there was a lot of competition but Lluis hung in there with my weak signal and pulled me out of the crowd after a couple attempts. THANK YOU FOR THE BIRTHDAY PRESENT Lluis!
Still wondering what a CPG is? Contest Point Giver! I am a really casual contester. Really the only reason I participate is that contests offer a fairly good opportunity to make some QSO’s. When you are QRP you have to do a lot of listening, plus pounce and search, but serious contesters will dig out weak signals to make the QSO’s so it is fun. I enjoy giving out points and reading the mail on ops that are faster than my cw comfort zone. Good practice, eh?
Here’s some photos from the day. Enjoy!

Had a great time setting up the C Pole antenna in a tree suspended configuration. My good friend and cohort, Jim Diggs, K4AHO came by with his AIM 4170 Antenna Analyzer and we were ready to tune the antenna and get a feel for it.
LESSON: A good analyzer makes tuning an antenna fast, simple and accurate! The AIM 4170 gave us a TON of info (most of it going over my head) and let us see how the C Pole was doing in several areas. Take a look at this output! (Click on the image for a larger version)
K4UPG C Pole Scan Results
LESSON: I followed Niel’s directions, but did not have a small plastic coffee container so used a Quart Coke bottle instead. So I call it a Coke Choke and it seems to work well. Here’s a photo to show it off!
Coke Choke Ready for Duty
I think this one is a keeper. Goes up easily, hears well and loads nicely too. I made a few brief contacts and called it a day, but look forward to more C Pole action in the days ahead.
p.s. Don’t forget to vote in the Ideal Ham Radio QTH poll on the blog!
If there were no limits (job, family, taxes, spouse, etc.) on where you could set up your ideal ham shack here in the USA, where would you go?
Think for a minute where the propagation, weather and other conditions create the ideal spot to operate. Then leave your vote in the poll on my blog and write a comment if you’d like to let us know why…
Nice to dream a bit, isn’t it?
p.s. Sorry and deepest apologies to the great state of Arizona… must be AZ Brain Freeze at work, it is on the bottom of the list until I figure out how to move it up higher in the software.
Orlando, FL btw
Labor Day here in the USA! So a day to play for most of us. Depending on the weather I may get a bit more on air time, but I have a project lined up too.
Some time ago I purchased a Deluxe Tuner kit from Dan’s Small Parts and Kits aka a QRP Mini Tuner by Mark L. Meyer as described in a 73 magazine article. It is a nice little set of parts and a schematic for the price.
QRP Mini Tuner Kit
So I’m thinking this holiday might be the time to build that little T tuner out and see if I can load up the downspout that runs down the side of my back porch. I’ll let you know how it works!
Hope the bands hold up. Tonight’s QRP-L has a message from N4QA about how nice 40m is sounding right now! Sure would be fun to have our bands back from the QRN and low sunspot streak of late!
Sunday I got the itch to get online. That means backyard portable when you live in an antenna restricted condo. So I put a card table up in the back porch and my 20 ft Jackite and 20m End Fed Half Wave in between the buildings.
Doggone noise and weak band conditions ruined the day so I decided to experiment with the new C Pole antenna that Neil W0VLZ had suggested. To get rid of a hunk of fiberglass gel inside the barrel of one of the Black Widow Crappie poles I used my cheapo Harbor Freight rotary tool which is a lame imitation of a Dremel tool but gets the job done. A few minutes of fitting and I was good to go.
I’m pretty impressed with it though conditions did not allow for any QSO’s yet. I cut the wire a bit longer than Niel’s directions but it tuned up 1:1 at 13.889 on my MFJ 207 Analyzer. At 14.060 it was a bit over 1.4:1 which is plenty usable. Next time out I’ll do a bit of trimming and be right on the money! Compared to the EFHW in a 20 ft L configuration, it did seem a bit noisier but with condx so difficult it would be hard to tell without some instrumentation.
LESSON: The C Pole is a pretty fine design. I need to work on the physical setup to improve the way the antenna hangs. The crappie poles I used were a bit too flimsy on the top section and leaned inward from the weight of the wire. A better tippy top support system is needed.
LESSON: Niel’s C Pole base design and specs worked very well. Lacking an empty plastic coffee can, I used a quart diet soda bottle of the same dimension and it worked very well for the balun section. With winds of approximately 15 mph and gusts to 20+ the antenna was stable and I did not use the spikes for the outriggers that I had prepared. Great work Niel. The weight of the base makes it a good choice for backyard or campground use.
LESSON: The C Pole would be a fantastic portable antenna sans the earth side supports. Chuck Carpenter W5USJ has posted a picture of this configuration. Take a look. One point hanger and spreaders at the top and bottom and simple stake to the ground for anchoring it and you are good to go. I will be testing this next time out by the lake. Winner!
LESSON: The off center fed dipole folded like this and deployed vertically is a good compact option for antenna restricted hams. I bit more work on the frame and support system may pay good dividends in stability and efficiency.
Hope to fly this new antenna in its tree configuration this weekend. I’ll update my results then.
This is the first of a weekly (Lord willin’) post of some of the lessons learned in the last week of playing radio in the field and on the workbench. I will be sharing my good and some of the not so good lessons with ya so ya don’t fall into the same holes that I have.
Our monthly Polar Bear QRP Club outing was last weekend, and I hustled to put together a new C Pole antenna using Niel W0VLZ’s description. After gathering all the parts I set about preparing them. With the 100F temperatures and high humidity, that was a chore since I don’t have a garage with my condo and use my back porch as the workshop. I also have a less than full set of tools and to trim the 3/4 inch PVC pipe to fit the bases of the 16.5 ft Black Widow Crappie poles I had to resort to my Buck knife.
I was a bit surprised how heavy the treated 1×4 lumber was. It certainly is not an antenna that is well suited to portable ops where it has to be carried very far.
Got the C pole components loaded into the car and transported to the nearby lakeside park in our development. It is a nice quiet spot with towering pine trees and without too many curious visitors, so its a nice QRP portable site. Got my new Coleman shelter set up and went to work on the C Pole. Oops… another lesson. In preparing the PVC to fit into the crappie poles, I only tested the two pvc poles fit into ONE of the two crappie poles. After lugging the framework, antenna wire, coax, balun, and poles about 100 yds to my site, I discovered crappie pole #2 had a big drop of fiberglass inside the open end of the pole and the PVC would not fit at all.

C Pole Aborted Setup by Ninja wannabe K4UPG
For the Polar Bears, it was a frustrating weekend for most of us. Propagation was spotty and noise level was as high as the heat. At least I did reconnect with my antenna lovin’ PB friend Aaron, N9SKN/2 working from his hotel parking lot in NJ and had a couple nice ragchews including Julio NP3CW who was 599 and despite two guys calling CQ on top of us was able to be copied well. Great QRP signal Julio.
As you can see, I went ninja and tied a piece of old tee shirt around my head as a sweatband. Actually I was emulating our Alpha Bear, Ron WB3AAL after I read of his early Appalachian Trail exploits and saw a photo of him in his youth and ninja radio mode. Well I tied it TOO TIGHT and left it on TOO LONG and came home with a painful big red stripe on my forehead that lasted for several hours and hurt like all git out.
Ouch Head for the Web... Don't try this at home! Grrrrrrr!

p. s. For our Summer Picnic Events, we are supposed to send a picture of our sammich that we have for lunch. So here is mine!
Until next time…

Now into the third week of my sabbatical, I am surprised how much I want to get out and operate my QRP portable gear. Guess I have deprived myself over the years of being a confirmed workaholic and avoiding time off, vacations, and time for my favorite hobby.
Grrrrr! The Polar Bears Are On The Loose!
This should be a good weekend for QRP portable. The Polar Bear QRP Group will be out for another Polar Bear Summer Picnic Event and Polar Bears from Spain to the West Coast of the US will be out looking for BSO’s. Grrrrr! I am PB #173 and we’re over 200 members now. With the new Twitter and APRS connections to QRPSPOTS.COM which also point to the excellent spotting site of K3UK with a section for FISTS/QRP Ops to spot and sked one another, there are plenty of ways to use technology to help find each other. Add in a few other contests and state QSO parties, and there should be some buzzing going on this weekend. Makes me wonder when the FOBB results will be announced! Buzzzz Buzzzzz
I’ll be out and if all goes well I will be field testing a new C Pole antenna based on the suggestion I received from Neil W0LVZ. I added some switchable capacitance to my BLT+ and have rewound the main toroid to see if I can push the range a bit more with it so will have a delta loop and probably my W3EDP in the air too. I love playing with antennas and am still amazed when the ones I build actually make contacts!
Give a listen for me on the QRP watering holes on 40m, 30m and 20m Saturday morning. I’ll be self spotting on QRPSPOTS and the K3UK sites to make it easier for you to find me. Let me know how my newest antenna is workin’.

After last week’s plea for antenna ideas for my antenna restricted condo, I received a good number of comments both on and off blog. Thanks for those… great food for thought. That is why I enjoy our QRP community. We don’t hesitate to share ideas with one another.
This morning as I took my daily walk around the lake, I met our condo association president. He graciously is allowing me to sink a pipe that will serve as a base to set up my Jackite poles in the backyard. I will be able to pop a cap on the top and keep the dirt and water out and just slide my fiberglass poles into the mount and be on the air in no time. YAHOO… that is a pretty good solution for now.
C Pole Antenna by W0VLZ
But being the antenna tweak that I am, I continue to look for the best alternatives I can find. I’ve started to put together the parts for the C Pole antenna that Niel W0VLZ pointed out to me. He has a fine site with lots of good QRP info too.
So, do you have another idea that can top that one? Or maybe you have a thought for what kind of vertical setup I might use with the new mount?
I’m standing by for my next project assignment.
