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.

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 Distracting View from my FOBB 10 Site

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!

W8DIZ Stops By to say Hello to K4UPG

K4UPG search and pounce FOBB 10

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.

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.

As one of the many antenna restricted condo owners of America, I cannot operate as often as I’d like. The hassle of putting up and taking down temporary antennas wastes time, isn’t always practical and generally spoils the fun for us.

Great that we have some holidays and time off as it allows a bit more opportunity to get on the air. The MI QRP group hosted a 4th of July Sprint and although the hour was late (7-11PM EDT) since I did not have to go to work Monday, I took advantage of the chance to work a few of my fellow QRP ops.

Rain and lightning welcomed my efforts to set up an antenna. So I forsook my normal setup and settled for a twinlead 44 foot doublet hung from my 20 foot Jackite pole which was bungee cord strapped to a ladder in the back yard of our condo. The antenna ran north south so much less than ideal, but at least I could get on the air.

Freshly Built NEScaf saved my bacon!

The day was saved by my freshly built NEScaf filter. As one of the lucky ones, I recently received the latest edition of this great kit provided by the NE QRP bunch. It enabled me to listen to cw despite the high QRN and background hash from neighbor’s TV’s, computers and air conditioners. What a joy it is to actually hear stations through the noise. This is a must have accessory for the condo based QRP op! I am still learning to use it well, but am mega-impressed with the capabilities it offers. With this audio filter, I could null out the QRN and peak the CW signals making for much more relaxed and enjoyable copy. The extra audio boost helps my little Sierra audio too. Keep watching for the next round of kits!

My favorite QRP group is the Polar Bear QRP gang! We have a good time and enjoy outdoors activities and trying to connect with one another at least once a month with some kind of activity. To escape some of the heat, I got an early start on the day. I wanted to try out a new mini-bac antenna configuration and knew it would take some time to get it up into the trees. BOY WAS THAT AN UNDERSTATEMENT! It was 110 ft doublet with a 40 ft feedline that was setup as a ladder line. Not an easy one to get up single-handed. Thanks to some tall trees, was able to get it up about 40-45 feet in the pine trees. It loaded great on 40m, but was disappointing on 20m so I ended up setting up my W3EDP in an L from my 20 ft Jackite pole to a nearby cedar tree at about 35 feet.  The sun chased me into the treeline where I settled in to chase bears.

My xyl Connie took a picture that shows the mini-back feedline hanging in the breeze after I shifted positions and setup the W3EDP in the shade. Grrrrr!

Osprey perched right above my head...cell phone picture

Was able to work a couple of the Polar Bears, Mike W3MC in MD and Guy N7UN up in the mountains on a trail(?) in NJ. I heard VA2SG but he was at ESP level briefly then faded away. I did hear a few others working him though. WA8REI was working Guy but I could not hear him at all and ended up tail ending their QSO to connect with N7UN.

Got to work a few others through the QSB and poor signal strength on 20m including Pastor Les, K4NK in SC, KE5SBZ, Ed in TX, N1FJ in MA, and Phil W3HZZ in Atlanta so it was a nice way to spend a few hours outdoors in the heat.

Connie brought me a picnic lunch and we enjoyed the osprey and bald eagle show as they fished Lake Fredrica.

Had to drink extra coffee to copy speedy W3MC's signal

This is the life... outdoors and ham radio...making QSO's...PTL!

Many work responsibilities have kept me off the air more than I’d like lately.

But we did manage to break away for a few days with family in Tennessee over Memorial Day. It was great to have an opportunity to get together with Chuck, AF4O the Hillybilly Bear and fellow Polar Bear QRP group member. We had an opportunity to work a bit of QRP portable in the Chickasaw State Forest in West Tennessee. It is a very natural and beautiful location and Chuck took me to his special spot in a very old and interesting cemetary set deep in the very tall hickory tree forest. Wow! I believe the latest date on the grave markers was 1927 and there were many from the early and mid 1800′s. It is a lovely and isolated spot.

Chuck said to bring along a screen shelter and I sure was glad I did! This was also a great spot for deer flies, hornets and other interesting biting bugs!

He had a nice setup and was running a random wire on 20m which he launched by throwing an antique glass insulator from an old telephone pole over a tree branch. He has a better arm than I do… think that heavy insulator would have broken my arm!

Back at the in-laws home in Jackson, I had some time to operate deck portable and was ably assisted by my niece Chloe. Conditions were horrible, but it was fun to be outside and hearing some sweet dits and dahs for a bit.

Now I am gearing up for the next outing of the Central Florida QRP group. The weather is HOT and the summer thunderstorms are back, but life and radio must go on… cu on the air!

Chloe gives me advice on copying cw through the QRN

On the road again… happy feet dance! K4UPG is loaded and ready for a good day by the lake operating the QRP To The Field event for 2010.

K4UPG ready to roll to QRP TTF site

Loaded with ALL the options!

Then came the wind knots in the antenna launching rig! I wanted to get a doublet up as high as possible. Took nearly 2 hours to get my antennas up in the air. LESSON LEARNED: It is really helpful to have another person along to help untangle all the knots that wire and string seem to make all by themselves.  Getting  the antenna up quickly is a key to portable ops. Grrrrr!

One of several tangled messes that delayed the antenna deployment

LESSON TWO: After a delayed start, I spent a lot of time moving my portable table to keep out of the direct sun! With temperatures in the upper 80′s it was HOT and direct sun causes my Sierra to drift a bit which makes qso’s more difficult. Need to get a sun shade setup and not waste time moving my position.

The band conditions were pretty poor and I did not hear as many stations as I had hoped. The ones I did work were tough going and seemed like others could not hear me responding to their CQ’s.  I didn’t even hear a lot of Florida QSO party ops, but sounds like others that were farther away did. In 5 hrs I managed three whole qso’s with TTF stations. I did hear one Polar Bear– Martin operating as VA3OVQ but he could not hear me when I replied to his CQ.

Warning sign about 30 feet from my operating site!

It was fun to be outdoors and playing radio! I did not get eaten by our neighborhood gator either! Maybe next time out will be better contact-wise.

Great weather, great site, and despite so-so band conditions but we made over 25 contacts to be able to submit our qualification of Hontoon Island, Deland, Florida as an official island to be listed and activated as a US Island On the Air.

The main picnic area near the ferry landing

The team consisted of Wally Crew, KG4LAL, Jim Diggs, K4AHO and Kelly, K4UPG. We used the special event callsign K4T on operated on 20m cw and ssb, 30m cw and a few unsuccessful attempts at 40m & 15m cw. Jim was our secret weapon on 20m with his good cw, K-1 and a Par End Fed antenna in vertical configuration on a 33 ft MFJ telescoping mast. Without his contribution we would not have been successful! So a big thank you Jim for your good operating skills and equipment that made it happen in less than 8 hours at QRP levels.

FL481 is ready for future activations!

Thanks to the Polar Bear QRP group, QRP-L members, 4 States QRP Group, GORC,  QRP Spots, US Islands organization and HF Packers that helped out by listening and attempting to connect with our effort on Hontoon Island. It was fun to work as a team!

Look out Hontoon Island the Polar Bear of Florida is coming your way! Good Friday, 2 April 2010 Polar Bear QRP member #173 (aka K4UPG) will attempt to qualify Hontoon Island as a US Island on the Air by making 25 contacts including at least 2 DXCC entities.

Hontoon Island is a beautiful place for some QRP Portable Ops

Activity will start about 1400Z after the ferry ride over to the island. Plan is to use special callsign K4T for recognition.

Look for us on 30m cw (10.106-10.116 MHz) and 20m cw 14.050-14.070 MHz and on the hour we will check 15m 21.060-21.070. If anyone shows up to assist, will also attempt ssb on 14.250-14.260 MHz island corridor. All ops will be QRP so we’ll need your help to pull us out!

***************************************************************************************

Fishing is good!

If things go well, our Central Florida QRP group may consider this as a new operating site! If you are in the area, come on and check it out with us.

Hontoon Island closes when the sun goes down!

Thanks to Florida State Parks for the fine pictures!

P.S. We did it 4.2.2010!  Over 30 QSO’s update coming! I am TIRED!
