Computer Does Not Save Time

Remember when we used to think computers would save us time?

Why did we think the computer would save us time?

I spent the last 6 hours running updates, fixing the problems the updates created and figuring out how to install the updates that would not install automagically. Grrrrrrr!

Think I need some time to play radio, but I won’t be taking a SDR radio with me for a bit. Grrrrr…. need to recover from the 26 reboots and all the time wasted surfing and reading the small print.

Good thing there is a QRP ARCI event this weekend and the following weekend is our Polar Bear Moonlight Madness Event. Grrrr! I’m ready for some CW. CU on the bands!

Duh: Learning Curve #5 Old Lessons Remembered

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.

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!

Duh: Learning Curve #4 Oops I did it again!

Ever see one of those tie bars or pins that say, “IYKDWYBDYKGWYBG”  My dad had one back in the days when men wore ties. The thing used to bug me cause he didn’t tell us what it meant right away. We tried guessing for a few days before he got tired of 7 kids all ganging up on him.

It is the famous If You Keep Doing What You’ve Been Doing, You’ll Keep Getting What You’ve Been Getting!” Not sure who gets the credit for that one, but it sure stuck with me all these years. Of course, I’ve heard my bosses recite it a few times along the way too.

Hole in the Head?

It only hurts when I laugh, or think, or move, or…use a new antenna in a contest!

That’s what this series of posts is about. Not repeating mistakes I’ve made. Maybe you can learn from my mistakes and save a bit of time. Or maybe you’ll just get a laugh and some relief from knowing someone else made the same mistake you’ve made. HA!

Well, last night, I did not follow my own advice. I put together a new antenna a few hours before the NAQCC Sprint and set it up. LESSON: As previously mentioned, don’t try to use a brand new antenna in a contest.

Ooops I did it again. Strike TWO! It was a disappointing night and too late to try to get another antenna up before the 2 hour sprint was over. So no contacts for me, I’m still scratching  my head. Was it the antenna, me, or the band conditions? BUT… I don’t think I’ll pull that one again. Unless I have a hole in my head…

p.s. Don’t forget to take the poll on my blog for the best ham radio QTH in the USA! It is on the left side column.

Duh: Learning Curve #1

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.

LESSON: Plan ahead and borrow the tools I need!!! YIKES.

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.

LESSON: Think about how something is to be used BEFORE using it!

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 setup

C Pole Aborted Setup by Ninja wannabe K4UPG

LESSON: Check ALL the parts and do a trial setup BEFORE lugging the stuff across the wet grass and wasting time attempting to set it up.

LESSON: Don’t use a new antenna for the first time when the goal is get on the air and have fun!

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

Ouch Head for the Web… Don't try this at home! Grrrrrrr!

LESSON: Baby Polar Bears should not try to be like the Alpha Bear and wear an unapproved homebrew sweatband. These can be hazardous to one’s health and well being. Don’t try this at home kids!

Cannot Get Enough QRP Portable

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.

PB QRP

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’.

Toe Dipping & Antenna Modeling

Tin Foil works!

I still think the tin foil does the magic!

After years of neglect, this analog era ham is willing to admit I only understand a bit about digital electronics. (Yep! Pun intended.) Well into the second week of my sabbatical leave, I have begun to plot out a course of study to get up to speed on the state of the art that I have so long neglected. Should be fun. There seems to be a good bit of open source help online these days and I have my trusty ARRL Handbook, Extra Class study guide, Antenna Handbook and assortment of other aids.

Any suggestions from the veteran techies out there will be greatly appreciated.

I am a learn by doing/hands-on sort of guy and find deep theory puts me into a semi-catatonic state after a few minutes.  For me, it’s a whole lot more fun to take a stab at things and find out if they smoke, and it also makes a lot more sense when I can dink and tweak and see what that actually does. But since that is a bit expensive, perhaps I should learn how to use software like spice to do simulations? Any recommendations for how to learn this software?

Another area of toe dipping will be learning to do antenna modeling. For years I’ve looked at those charts and made little sense out of them. HA… I like to throw wire out and see what happens, but in the summer heat, maybe it is wiser to do a bit of modeling from my air conditioned den?

Thanks WX7S– Your site looks AWESOME for learning this stuff!

I’ll try to share some of the learning curve, but would love to hear from some of you that have gone before. Shortcuts are nice. WX7S your site looks like a great place for me to start! Thanks for the effort it takes to do that.

This weekend (Sat 14 Aug 2010) the Central Florida QRP Group will gather for breakfast at 0730 (Denny’s in Sanford, FL) and off to Sylvan Lake Park in Sanford, FL at 0900 EDT to operate. If you like cw and qrp or are just plain curious… come join us!

FOBB Ain’t Broke… SO…

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!

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.
