Unfortunately, Mother Nature has not been cooperating. I’m writing this from Costa Rica and we’ve have a lot of rain here. I was able to get on the air very briefly after arriving on Sunday, making a single contact on 20m mostly just to make sure that the gear was working. I got a little bit of RF into the radio (which I’d seen while testing at home) but the ferrites that I’d brought cleared that up.

The next time I was about to get on the air was Tuesday afternoon, also relatively briefly. I set up for 15m and the antenna behaved very well there, easily tuning the whole band. I worked a few stations in the US southeast (Georgia & Florida) and a relative local in Venezuala. But as the title of this post indicates, rainy season has started here and it’s been raining a lot since then.

Obviously a Buddipole will work in the rain, but the way things are set up here it’s not practical to leave the antenna up and run out in a near-monsoon to make an adjustment to a whip. Of course, trying to do that when there’s lightning around, which there has been, was an even worse idea.

Wednesday was pretty much a complete rainout, though my friends and I were able to go out on the water and jet ski for a couple of hours. (No, I did not attempt to operation TI7/K2DBK/MM). Did I mention that it rained constantly during that whole time?

Today (Thursday) started off looking bad again, raining for most of the early morning, but it did clear up for the majority of our day which included a sightseeing tour to the Rincon de la Vieja volcano. Right at the end of that trip it starting pouring yet again, and while there was a very brief respite after we got back to our residence here, it’s been raining steadily ever since along with a lot of lightning. Needless to say, no radio.

The weather forecast for the next couple of days calls for more of the same, although our touring plans are done and since we’ll be around more I hope that if we get a break from the rain for a few hours I’ll be able to get on the air.

I am disappointed that I haven’t been able to get on the air more, but I’m trying to stay positive and see if I can get on the air for at least a few more hours before it’s time for us to leave.

Welcome to Handiham World!

Have you ever wondered where you saw that article about the antenna that you could build yourself and that would actually fit into your real estate? What month’s QST was it that had the review of the rig you’re thinking about buying? What’s in QEX, the “Forum for Communications Experimenters”? What about the National Contest Journal?

If you’re anything like me, you probably subscribe to several magazines and don’t really have the time to read every article. I always go through the contents and page through to see what jumps out at me, and in the process I find plenty of interesting articles that I am going to read later or save for reference. Before I know it, the next month’s magazines arrive and I am falling behind in my reading. I’ll have much more time in the winter, so the magazines go on the shelf in my ham shack, ordered by month. Sometimes the articles I wanted to read just never get read, and the reason is that they are too hard to find. It may be that I don’t even recall the title of the article or the author’s name, just the general topic. True, the periodicals search tool on the ARRL website will be helpful, but sometimes I can’t locate the article I want because my shelves are not organized as well as I would like.

I can see to read the print articles. Doing this kind of a search when you are blind can be a much more daunting task. That’s one of the reasons we will be installing the 2010 ARRL Periodicals CD-ROM on a Windows computer equipped with JAWS®, a popular screenreading software program by Freedom Scientific. The upcoming Handiham Radio Camp provides exactly the right opportunity for us to test the accessibility of the Periodicals CD using a screenreading computer operated by experienced blind amateur radio operators. The idea of having an entire year’s worth of QST, National Contest Journal, and QEX, the Forum for Communications Experimenters, available on a single CD with search capability seems a lot better than saving print publications on a shelf – or shoeboxes full of audio tapes or even the new flash memory digital NLS “books”. Most of us just don’t have the space to save more than a couple of year’s worth of old print magazines, and even if we do manage to keep them all in order, finding a particular article can be a chore, so we are looking forward to exploring this ARRL CD during Radio Camp.

One book we have never put onto tape for our blind Handiham members is the ARRL Repeater Directory. Think about it for awhile, and you’ll realize why. Not only would it be like reading the phone book, but it would also be impossibly difficult to use because you could never find anything in it, especially in audio cassette format. Imagine back in the days of books on tape what such a book would be like for a blind user. It would be a box full of cassettes, and one would have to keep them organized carefully. Even then, who wants to listen for hours to find the right spot on a tape that has just the repeater information you need? The lack of an accessible repeater directory for blind hams has been a problem, and even those of us who can see to read a print version can find the lookups of repeaters while traveling a hassle. That’s where the ARRL TravelPlus Repeater Directory on CD comes in handy. While I seldom plan to tote along a notebook computer just for repeater lookups while driving cross country, I do appreciate the pre-trip planning capabilities of the ARRL software. Once can print out a list of repeaters within a user-defined distance along a planned route. That saves the hassle of paging through a print repeater directory during your trip. I find it much more intuitive and easier to use, but what about our blind Handiham members? Would there be some features of the ARRL TravelPlus CD that could prove useful? That is what we are going to find out at Radio Camp in August when we install the software on our JAWS computer and see what we can do with it.

Handiham Radio Camp is August 8 through 13, 2011 at Camp Courage near Maple Lake, Minnesota. The camp repeater, W0EQO-R, is connected to the HANDIHAM Echolink conference and the Vancouver, BC IRLP node 9008. We also plan to have our own experimental low power IRLP node 7051 on the air. The camp station is W0ZSW, and will be operating on the HF bands.

News of Mumbai bombings arrives on Handiham net

I was surprised to hear about terrorist bombings in Mumbai, India from Vispi, VU2WLL, on today’s Handiham Echolink net. He says that he and his sister are both all right. The news media have conflicting numbers of casualties. There will no doubt be much more information later on today as this story unfolds. In the meantime, our thoughts are with the people of India as they cope with this senseless violence.

 

Exposed PCB

Model P6 CWtouchkeyer

Model P6 CWtouchkeyer http://www.cwtouchkeyer.com/P6.htm

“The PC card is exposed to reduce assembly cost and material cost to provide a low cost touch paddle. The model P1PAD would be the next option.  It’s twice the size and offers a weight in it. The P6 is designed to be low cost, light weight yet hold the touch standard as with all my products.” Summer, from CWtouchkeyer.com says, “I’ve had a few comments about the exposed PC card but less than 1%.”

I wanted to protect the PCB from potential short circuits that might damage the Touch Paddles.  I ordered the P6 because every radio I have already has a keyer onboard. A quick scan of the CWtouchkeyer.com web site will show you various models with better and better features.

I like to tinker and one of my favorite things to do is to use something for ham radio for which it was not intended. The Old Bay spice can was just the right size for this job. The can was almost empty anyway. I was going to mount the entire keyer inside the Old Bay box but eventually decided that was overkill. Modifying the cover was pretty easy. I used a Dremel tool to rout out the cover lip so it would fit better on the PCB. I used ‘Whiteout’ to drip a mark onto the Old Bay Cover through the screw holes of the PCB for its rubber feet and main cover screws.

The hardest part of this job was getting all the wire back in the box, and whole thing put back together without pinching the wire. It took longer to write this blog and get the photos properly displayed than doing the actual work.

Using these paddles is not exactly the same as using mechanical paddles. You cannot ‘rest’ your fingers on the metal tabs. Touching the metal strips sends a stream of code out. I learned to keep my wrist steady to avoid sending extra dits. The learning curve is not as steep as I first suspected it would be. My fist improved after using the touch paddled for just a short time. Using them if fun. I plan to try various CW speeds on my radio keyer just to test myself and make sure I don’t embarrass myself when I go on the air.

I tested the paddles with very low power into a dummy load. So far so good. Now I’m looking forward to using them on the air.

The P6 is a very light weight model and can be held in your hand to steady it. I like these paddles so much that I am thinking about getting a second set and boxing them up in a different kind of enclosure and weighing it down to keep it from moving around. That will be fun to play with indoors with my 100 watt radio.

Elecraft KX3

KX3 Transceiver (Preliminary)
Note: This is advance information. Specifications and option/accessory availability are subject to change without notice.
KX3 Ordering and Shipping dates will be Fall-Winter 2011

• 160-6 meters, SSB/CW/DATA/AM/FM modes
• 0 W PEP (100 W with KXPA100 amp)
• Only 1.5 pounds (0.7 kg)
• Current drain as low as 150 mA

I have been following the story about this rig ever since I found out about it. I am very excited about it, especially since the QRP community lost a source of rigs from Icom

The Icom 703 is no longer made. I have two of them. One has a SSB filter and the other a CW filter. If one breaks I’ll still have a back up. Although the 703’s are fine rigs and I have used them for years without the need for repair, Its nice to see a new rig coming to the QRP market.

I am eager to get my hands on this new Elecraft KX3. I have a Kx1 that I like very much but this new one has a lot of promise.

http://www.elecraft.com/
You can put your name on a waiting list at Elecraft at the web site listing above. I hate to wait when I have money for a new rig burning a hole in my pocket. As luck would have it, by the time my number comes up here. I’ll have spent it on something else.

Even worse, there is no price on this radio yet. We can only guess what it might be!
I am very satisfied with the KX1 and I look forward to the same quality from Elecraft on this new KX3 radio.

I’m curious!

How many readers of Amateur Radio.com are seriously interested in buying one of these babies! I think it would be fun to know how much interest this new offering from Elecraft has generated.

In your reply, tell us about how you plan to use this rig. Also include how many and what kind of QRP rigs you use and which modes you operate these rigs in. Is this the rig you have been waiting for?

I’m always interested in what other QRP’ers are doing and what they are thinking and planning. I’ll bet others would like to hear from you too.

Its been a long time since the FT 817 was introduced and likewise the Icom IC 703 in its various iterations.

As I wrote previously, for 2011 Field Day, I made a game of trying to contact W3AO and KE3Q on as many bands and modes as possible.  Here are the official standings from KD4D who managed the PVRC competition:

So, K1DQV was at the top of the heap (with a 2-meter CW contact, I might add).  Anyhow, I’m quite pleased with the results and happy to report that W3AO is claiming the all-time high QSO total for Field Day this year.  Congratulations.

Early Monday morning, the day after Field Day, we welcomed our son Evan into the family.  We were so right to stay home!  As good friends have opined “your life will change…for the better.”  So far, I would tend to agree.  The blog will receive (even more) infrequent updates, K8GU may be a little less active on the air, and there will be fewer homebrew projects over the next few weeks and months.  A few months ago after building some UHF antennas when I pinched the palm of my hand with a pair of pliers, I watched the blood blister heal and commented to Sarah on how amazing it was for several days straight.  “You think that’s amazing?  Well, I’m growing new life inside of me.”  We laughed, but it’s very true.  Every day is something new:  grasping, gazing, grunting, and gurgling.  This is only the beginning.  That’s pretty amazing.
