QRPGuys Iambic Paddle Build

I’ve been practicing a lot of CW lately and had ordered a QRP guys iambic paddle from their website qrpguys.com awhile back. I went to the CW class on Saturday morning, which got me in the CW mood. After knocking some items off the honey-do list I was getting a little bored on Saturday night so I headed down to the shack and dug out the iambic key kit I had ordered.

I’ve never done any kit building or anything slightly engineer-y until joining the club. I don’t always understand why things work and building kits (even simple ones help me along). This kit didn’t look too hard, although it has a 4 out of 5-star difficulty rating on their website, so I jumped right in!

I made sure I started by sorting out all the parts in an orderly fashion.Iambic Paddle Build  I learned this much from working countless hours after Christmas and birthdays on Star Wars lego kits that are made for children, but built by adults after the kids get frustrated 15 minutes after starting!

I then got to the fun part of soldering. This was different than what I’ve done in the past as I started with soldering all the mechanical parts together by applying a small amount of solder and then checking to make sure everything lined up before putting a lot of solder on. Iambic Paddle BuildI enjoyed this as it was a large area to solder and it didn’t matter so much if my soldering skills aren’t very good! There were only a few electrical components to solder and that part was rather easy, even for my limited skills!

The toughest part of the whole build was assembling the paddles. You can see from the picture there are four nuts (and lock washers) that are to be assembled on the inside of the paddles with very limited space. TIambic Paddle Buildweezers were an absolute necessity – and earplugs for any youth that may be hanging around. After many – and I do mean many – attempts of dropping and picking up nuts and washers I finally got the washers and nuts in place and fastened.

I was thrilled to have succeeded and ran out to the car, where my radio is hooked up at the moment and gave it a quick test run. Below is my not-so-professional video which shows my not-so-professional CW skills.

The paddles work well. The black pads do stick together a little when you push on both paddles at the same time, but I am very happy with my tiny QRP paddles! I am thinking of cutting slots in the sides and attaching a velcro band to attach to my leg to keep the paddle in place in the hopes that I could operate it with one hand. Let me know what you think or if you’ve built this kit before.

Our Ham Radio Video and Photo Collections

We have been building quite a collection of Ham Radio video and photos over the past few years. We have pictures and video from Field Days, Contests and Activations, Club Meetings, Tech Nights, Youth Events, Picnics, Classes, and other Member Activities.

We’ve decided to collect all of this great content in one place here on our website so that our members can enjoy it. You can view it via the following links:

Take a trip down our Club’s Memory Lane or catch up on some topics from one of our many Tech Night sessions. There is lots of material here to use for fun and learning.

Most (but not all) of this content is in members-only sections of the pages so be sure to log in to our website to view all of the media that we have collected.

Thanks to all of our members for making so many great memories! We are looking forward to much more to come…

QRP on the AIR… from K-ONE Last Good Question

By Dennis Marandos – K1LGQ

What a difference 90 days can make! It wasn’t that long ago we were looking out our windows and pleading with the snow gods to give us a break, and finally, our cries were heard. The temperatures, the blue skies, the winds have all been recently favorable and we can’t even remember what it was like with four-foot levels of bleached, hard bursts, hoar frosts in our front yards and drifts even higher. Well, we would much prefer to forget last winter than try to remember forging paths to the house garage, the grocery stores, to work or simply just getting our mail in the front yard–but look at it now. The sun is higher in the sky, the temps are thirty to forty degrees warmer than before, and the winds have shifted, a bit, for us to say “We’re in pig (HAM) heaven!”  What does all this lead up to you say? It is nature calling us to get out of the stale-air shack and into our “get-off-our-fanny” modes…including hiking, camping, biking and just plan QRP along the mountain paths. Yes, it’s the call of the CONTINUOUS WAVE!

Dennis K1LGQ, Mr. QRP

I have been waiting all winter for the warmer spring months so I could pack my QRP gear into my knapsack, charge up the ole gel-cell and retune my throw-up dipoles to GET ON THE AIR. I have a small 7-amp gel-cell which is pretty much all anyone needs and thin, copper wire to fling onto the nearest tree limb to get the RF into the ionosphere. A quick and grubby antenna tuner will certainly do the job plus its pocket size which means not a lot of space occupied in the QRP bag. Overall, it’s pretty easy and if you’re thinking you have to do a lot to visit Mother Nature’s playground in her best, you’re wrong. Outdoor operating is now easier than it has ever been, and I am going to tell you why.

First off, operating QRP means you take the least favorable weight, carry less with you, and enjoy what you have. Five watts, or less, is pretty slim-pickings and to throw an antenna into a tree is the least of your hardships, but getting outside into the woods, the parks, the BACK YARD is going to be your toughest struggle. Where can I go? Who can I go with? How much gear do I need? Do I need to bring food, coffee, or snacks where I am headed? OH COME ON! We’re talking simply getting outside and into the sun and on the air!

I have built over two dozen QRP transceivers and perhaps as many antennas as well for the trickiest trees around. What you need is simply a low power rig that can be easily driven by six or eight double-AA batteries, or even a Lithium alone will get you on the air and you’re in attendance. Have you checked the pages of CQ magazine or QST to see who is selling QRP transceivers? Or better and easier, ‘Goggle’ QRP kits on your computer and you’ll find a utopia in front of you. Come on, the longer, brighter, sunshine days are here and you need to get moving before that cool breeze from the north comes visiting again. Not to worry, it’ll be a while, so warm up the soldering iron and burn some rosin. Just target the “al fresco” rig and get moving. By the way, bring your key, paper, and chronographic meter as well.

What does it take to get you moving? Okay, let’s suppose someone offered you fifty dollars to join him on a hike. Now, you’re outdoors and you’re loving it. Well, tell yourself that simply taking your gear to the woods is worth more than fifty dollars and look how much you saved. Think of mind relaxing thoughts, soothing, refreshing sunshine and the thrill of working QSOs anywhere someone can hear you. Now—doesn’t this bring a little excitement to your hard pressed schedule? YES, IT DOES! Now get moving…!
