Two Additions: MTR and Begali Adventure Key

It's always nice to get new toys. Toys are usually never in the category of "needed", but almost always in the category of "wanted". Over the past week I've had two new additions to the shack that are definitely "wanted toys"

I received the Begali Adventure paddle. What a work of art. This paddle is another example of the precision workmanship found in Begali keys. I installed the key on my KX3 (you must plug the key into the key port on the side of the radio) and it is pure joy to operate. So a KX3, with a Begali key, this isn't your your Dad's QRP. Most luxurious.

The key also had available hardware that will allow this key to be used with the KX1 and FT-817.

This week I also received from TJ, W0EA, my Mountain Top'er Rig, MTR, a KD1JV designed 2 band QRP radio. This is a SMD kit that I asked TJ to build for me since, at the time, I didn't really have any experience soldering SMD components. My MTR is set up for 40m/20m operation, CW only. It is very light and is well designed. I made my first QSO with W7WHO shortly after taking it out of the box. I look forward to using it on SOTA activations.

Oh the temptations of QRP gear. Right now I'm a happy camper.



Four Days In May: A look back at FDIM 2012…

Four Days In May is sponsored by the QRP ARCI

Four Days In May is sponsored by the QRP ARCI

One of the highlights of my trip to the Dayton Hamvention last year was attending evenings at Four Days in May (FDIM), a QRP convention sponsored by the QRP ARCI that rather conveniently coincides with the Dayton Hamvention, which I try to attend annually. Though scheduling makes it difficult for me to attend all of FDIM’s daytime presentations, the camaraderie and innovation one discovers at the evening sessions is wholeheartedly worthwhile.

Last year, I snapped quite a few photos at FDIM which I planned to post following the Hamvention. Unfortunately, shortly after the Hamvention, my laptop began displaying signs of an early demise.  In haste, I archived my photos on a portable drive, where they remained buried for a year.  I just rediscovered this photographic treasure, and thought I’d share it with readers; looking through them rekindled my enthusiasm for FDIM 2013, which starts next week!

A quick look at FDIM 2012

A great characteristic about FDIM is the array of QRP products offered by QRPers for the community. More often than not, these products are fairly priced, and often in support of the QRP community rather than major profit-making ventures.

For example, the North Georgia QRP Club produces affordable wood stands for QRP rigs. They’re incredibly simple, but fully finished and beautifully designed, just the thing to prop up your QRP portable at the right angle for desktop use.

These wooden stands support the following rigs:

  • Elecraft K1, KX1
  • Ten Ten R4020/R4030/R4040
  • Yaesu FT817/FT817N
  • Hendricks PFR3

The club can even accommodate custom orders for other rigs. Check out and purchase these on the NOGAQRP website.

Speaking of wood products–one vendor last year featured an amazing array of wooden paddle pieces and even custom wooden tuning dimples (spinner knobs) for the Elecraft K2 and K1.

As you can see from the photos, each piece is perfectly finished and has great character, as one might expect of real wood.

I also ran into Dennis Blanchard (K1YPP) and his wife, Jane, who were signing and selling their books. I wrote a review here on QRPer about Dennis’ story of the challenges and joys of through-hiking the Appalachian Trail. If you haven’t read Three Hundred Zeroes: Lessons of the Heart on the Appalachian Trail, you’re in for a treat. I’m hoping Dennis will attend FDIM this year.

Dennis, being a hard-core QRPer, trekked with ham gear in tow; he brought his kits to FDIM:

There were a variety of keys and paddles to be seen, of course; offerings range from the home brewed to gorgeous Italian Begali designs:

One paddle that really caught my attention was QuadraBug, a creation of WB9LPU. What makes this gem stand apart from other “Bugs” is that not only will it form “dits” automatically, but it also forms “dahs.” Truly, an amazing work of engineering. I searched the web for a video of the QuadraBug in action, but found nothing. [UPDATE:  Thanks, Yan for finding a video! See video below.]  This year, I’ll take a video if I’m fortunate enough to see it again.

Home-brew galore

There were an amazing number of home-brewed projects on display, and even a home-brew contest. I didn’t capture photos of them all, but I did manage to snap a few.

One that really caught my eye (being a shortwave receiver enthusiast) was David Cripe’s (NM0S) version of Hutch’s Radio. The original Hutch’s Radios were built by US and British POW’s in WWII. Built in canteens, often from confiscated parts, these radios gave POWs hope by allowing them to tune in the outside world, via the BBC WS and Voice of America. In the spirit of the original, David challenged himself to build his version prior to FDIM, with original parts of the era, and in “secrecy.” Secrecy? As many of the components had to be purchased from suppliers on eBay, David tried to intercept all of the incoming packages without his wife noticing. His success was brief–alas, his wife discovered the mission–but fun; still, the end result was a very cool piece of historical recreation with a humorous story to match:

Of course, FDIM featured loads of QRP transmitters, receivers and transceivers; here is Dwayne’s (AK4P) 40 meter transceiver, built in a SPAM container:

IMG_1382 IMG_1385 IMG_1386

Terry Young, K4KJP, built a very cool pocket 20 meter transceiver in an Altoids tin:

IMG_1379 IMG_1381

And Alan Shapiro, NM5S, should have won a prize for the most compact set of CW paddles.  These paddles are so small that they can be clamped onto your log book. Much to my surprise, they were amazingly easy to use, and would be a great addition to any field-portable radio:

FDIM 2013

If FDIM 2012 is any indication (yes), this is a mere sampling of the stuff you’ll see at Four Days In May 2013.  I encourage you to attend: if nothing else, make a little time either Thursday, Friday or Saturday evening to visit the evening displays at FDIM–they’re free and open to the public.

If you can’t attend, I hope you’ll earmark your calendar for a future date. I do plan to bring my camera again this year and will share some photos. Hopefully, I’ll post them a little earlier this go-around!

Hope to see you at FDIM and the Hamvention. For the third year in a row, I will be representing my charity, Ears To Our World (ETOW), at an inside exhibit at the Hamvention. We should be in booth 601 in the East Hall. Please feel free to stop by and introduce yourself! (And if you feel so inclined, you can even donate a few bucks to our worthy cause.)  See you there–!

Best & 72,

Short time on the radio netted 37,968 miles per watt contact.

Last evening I had a very short time on the radio I was not expecting much as the conditions have not been stellar. I did find 20m to be very busy and not reflecting the solar conditions. On May 2nd I was able to work EA4DRV and last night I heard him on again calling CQ. I gave him a call and made the contact with only 100mW's for a miles per watt of 37,968! Shortly after my contact I heard him giving a report to fellow blogger Larry W2LJ. I was only able to hear Larry very faintly just above the noise level. I did do a little more fishing but time was tight and I had to shut things down for the evening. This evening I think I am going to throw the line out again and see how the fishing goes!

Alexloop on the deck calling CQ

RBN spots (click to enlarge)
The weather once again was great and I wanted to take the Alexloop out onto my back deck to see  how it would do once again. The other day I had no spots at all but this day was a complete different story. I was operating  my KX3 at 3 watts. The antenna as was already mention is the Alexloop mounted on a tripod. I called CQ on 20m,30m and 40m it was the late afternoon and nothing could be heard at my end at all. I was spotted only in the States but conditions have not been all that great. I did hear some American stations on 30m but they were just at the noise level. By the spots on the Reverse Beacon Network my signal is getting out! I am excited to see how this antenna does once the condition improve.

QRP TTF 2013 Contest Point Giver Report!

Last weekend was a fun one for me. I had an open day following a morning commitment, and then I was free to operate in the QRP TTF event. I had originally planned to strike out to a nearby trailhead for the extra multiplier but a hastily planned meeting nixed that plan. So I operated from the park area by Lake Fredrica in our housing development. It is my favorite spot due to the nicely spaced tall pines and open area to a sandy beach on the lake. The lake is spring fed and one of the clearest natural lakes in the area despite being surrounded by civilization. It is also a nice quiet RF location free of most appliance generated noise that is so common these days.

Being a dedicated Contest Point Giver, I set out to give some points to the serious ops among us. What a treat to casually listen, and try to improve my cw copying speed by listening to all the exchanges going on during events like this one. I love the fact that the SOTA gang was included and there were a few Florida QSO Party ops on 20m where I spend most of my time. It was also Polar Bear QRP monthly outing time and I got to Grrrrrr to several of my fellow Polar Bear ops.  Thanks and an extra long Grrrr to Larry W2LJ, Perry N5PJ, Barry N1EU, and John N0EVH and hope I did not miss any other PB’s.

In the end, I had a fun day. Seems the bands were not solid, but I’ve gotten used to that in this current solar cycle. I kept hearing the same stations over and over. Now and then a new call would appear but most of the time they disappeared before I could work them with my Sierra at 2.4 watts. Even with my jumper dipole up at 45 feet I suspect my signal isn’t always loud enough to attract much attention. So I search and pounce and enjoy reading the mail and waiting to pounce. I did collect 14 different states and give myself a bit of multiplier for that fortunate turn of events.

Nothing like spending time outdoors doing something that I love. I especially appreciate my fellow QRP ops and the fun we have making QSO’s with limited power and gear.

CU on the air!

A nice way to rest a sore back.

Relaxing on the deck.
Last evening myself and a bathroom mat had a little hip hop time.....translation.....I was standing on a bathroom mat lost my balance causing me to "hop" and out went the hip!!! Today it was no work, off to the Chiropractor and physio. The good news is no disk problems just muscle but I still have to be very careful as I do have lower back disk issues. So what does this have to do with ham radio....nothing....BUT this does...It was a very nice sunny day out and I wanted to relax on the deck and not become board, so I gathered up (very gently) the KX3, Alexloop, Sony MDR-V150 head phones and a pad of paper.

Some things I tried with the Alexloop
1. I emailed Alex regarding his opinion about adding some extra coax so I did not have to be that close to the loop. He (as always) emailed me back within 10 minutes explaining there should be no problem doing this. At first I did try 12 ft of RG 213 and found I could not get a decent SWR. I then tried a 6ft piece 
and all was well. This would allow me to sit at the patio table and not have the loop under the patio umbrella.

2. When tuning the loop if I was in front of the loop while adjusting it's capacitor I found I could get a 1.2.1 match on 20m..but..as soon as I moved my hand away from the loop the SWR rose to 2.1.1. I found by adjusting the loop from the back of the antenna the SWR was not affected. 
New loop to tripod adapter

3. In the past I was using plastic zip wraps to attach the antenna to the tripod. I made and wanted to try a new antenna to tripod holder made of plastic pipe and heat shrink. It turned out to work just fine and will allow me to set the antenna up much faster in the field. 
 
I called CQ on 14.060 for about a 1/2 hour and was not spotted on the Reverse beacon network. This does not concern me as conditions were not that great. It was not my plan to really make any contacts but the see how the loop fit on the deck. Also how the new adapter I made fit both tripod and Alexloop.  Regarding the Reverse beacon network not sure if it is up and running properly today. I tried to refresh the spots and it seem to get stuck trying to refresh.

Poor conditons but still worked a few…………..

Throughout the day yesterday I was getting propagation updates on my Iphone, things were not looking to good. The decision was made to work on my Elecraft K2 build and not get frustrated with poor propagation conditions. After about 20 minutes of working on the K2 I just was not getting into. Putting the project down for the evening I flipped on the K3 just to check out the band conditions. One of my handy tools for doing that is the Elecraft P3. It's great for seeing the general condition of a particular band. It seemed that 20 meters was not doing to badly considering the conditions. The first station I ran across was H70ORO from Nicaragua. His signal was rather strong considering my attic dipole does not seem to favour Central or South America. His code speed was a comfortable 20 wpm and really not much of a pileup. I made contact with only 1 watt which gave me 2,190 miles per watt contact.
The next (and final) station I contacted was EA4DRV, being pumped from my last 1 watt contact I tried working this Spanish station with 1 watt. It didn't work out as well and the contact was made eventually with 3 watts. After this contact it was time to flip the switch once again and move on to making lunches, arranging morning work clothes and all that other fun stuff.  It goes to show you that even when the propagation is in the dumpers contacts are still there to be had!
