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.

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.

I’m not shy about expressing my opinion if I feel that I’ve been wronged by a company or product. Amateur Radio operators are the ultimate social network. Hams talk — quite literally. If you market a product or service to hams, you must be prepared to have every aspect put under a microscope. If you create poor products, or don’t stand behind them, you had better be prepared to find another line of work. While I can think of a couple of examples in our hobby where crappy companies continue to survive, it is mostly due to the lack of a suitable replacement. While I’m quick to complain, I’m also quick to offer up well deserved praise.

Enter Smiley Antennas. I’ve been buying their products for many years. They are well constructed, high quality, and customer service is always top notch. If you’ve never purchased one of their antennas for your HT, I believe that you are really missing out. In fact, whenever I buy a new or used HT, the first thing I do is throw away the stock antenna and replace it with a Smiley. Their 270A Dual Band antenna is small, sturdy, and really makes a big difference, especially when I’m trying to hit those distant 440 machines. In my opinion, it’s the best $22 you can spend to improve your signal.

I recently had a need for a customized HT antenna for a very specific application. Within a week of ordering it, I had it at my door. A custom HT antenna built to order. Incredible.

I couldn’t recommend this company more. Check them out at http://www.smileyantenna.com or you can call them at 1-800-527-5439.

It’s always a pleasure to recognize publicly a company that goes above and beyond.

Less than three weeks ago I wrote of having a bit of a headache. Since then, a lot has happened. I went to hospital in Newcastle, where it was discovered that I have a brain tumour. I was going to write about all of that in a bit more detail but things didn’t turn out quite as I hoped they would.

If you’ve never heard of Burt Fisher, K1OIK, then you’ve probably been living under a rock. Well, not quite. But the video above has garnered well over 90,000 views in the couple of years it has been online. In the world of Internet video, that’s fairly respectable. How does he do it? By making fun of just about every aspect of our beloved hobby, that’s how!

Many people will view the video and get upset. Or they’ll be offended. Or annoyed. Don’t worry, that’s just what Burt was hoping to accomplish! But there is something more to this video than just some jerk on the Internet with an axe to grind. More than trying to tick anyone off, I think he’s trying to get you to think. To turn a critical eye on what we do and why we do it. To self-evaluate and change the parts of Amateur Radio that don’t make sense or that are self-destructive. He makes some good points. Some may not like his condescending style, but do you know why he’s so annoying? He’s very often right.

Don’t get me wrong. I love my little Yaesu FT-60 dual-bander.  Before this radio, I always owned Kenwood HTs and they were great. But I couldn’t pass up this little gem for under $200. Yes, it has a NiMH battery instead of lithium ion like those new Wouxuns. No, it doesn’t have cross-band repeat like some of those other HTs. But it’s reliable. It’s small.  And it’s a great value.

Why am I complaining?  I hate the speaker mic jack.  Specifically, I hate that whenever I use my speaker mic it always starts to fall out of the jack a little bit.  Not a big deal, right? Well, unfortunately as the plug starts to come out (and we’re talking just a millimeter or two), it keys the transmitter until you notice it.  If you have a big mouth like I do, this can be a problem.  Besides potential embarassment, you run the risk of interfering with other QSOs.  And if you’re running EMCOMM, for which this radio is very popular, it could interfere with more important traffic than run-of-the-mill ragchewing.

This sort of thing never happened with my Kenwood rigs with their two-plug (3.5mm/2.5mm) connections versus Yaesu’s all-in-one single (3.5mm) stereo phone plug.  It’s compact, yes.  But it’s not as stable. And trying to jam everything into one plug creates problems like this.

Has anyone else noticed the same problem?  If so, have you developed a fix for this wandering plug (short of a tight rubber band around the radio)?

All the news sources–I saw it on Yahoo!, of all places–are churning out stories today about the current state of the surface of the sun. Three different “experts” have issued dire predictions about the sleepy sun and what it means for mankind…and not just us hams, who enjoy bouncing signals off an ionized atmosphere.

You know as well as I do that simply saying this cycle is slow to develop is not going to attract much reader interest. But if you say there is the possibility that the dormancy of Ole Sol portends historic implications, that it could reverse the effects of that evil, man-made global warming (or make it even more dire), that there could be unknown but potentially catastrophic weather events as a result…heck, even that we are on the verge of another Maunder Minimum, when the sun went to sleep for 300 years and we entered a “mini-Ice Age!”…then you will get some attention. Attention to your columns, your websites, your blogs, your books, your speeches.

I know it is human nature to see things from a very narrow perspective. Understanding things like climate change that usually take eons to be obvious and drawing conclusions about variations in sunspot minima and maxima that only occur in eleven-year cycles are difficult for us mortals to do. Geologic time and cosmologic time and distance are impossible for us to comprehend in our simple little seven- or eight-decade life spans. That’s why all the junk about rapid climate change (which I consider normal weather variation and based on decidedly short-term data) has found so many who are willing to swallow it, hook, line and sinker.

I admit I know little about sunspots or solar weather, beyond the fact that more spots equal better propagation on the high-frequency radio bands and pretty displays of the Northern Lights. And I appreciate data and scientific observation. But seems to me that it is far too early to say the sun is going to be dozing for the next three centuries simply because cycle 24 is a tad bit slow to get moving. After all, many of these same “experts” were touting what an active cycle this was going to be…and they were doing it only a year or so ago.

Reminds me of the high-tech “weather rock” my wife has in her flower garden. “If this rock is wet, it is raining. If it is dry, it is sunny. If it is white, it is snowing.”

I’m still hoping for an active solar cycle. I have somehow managed to be inactive in my amateur radio activities during each of the past two cycle maxima, and I had high hopes for that “arm-chair” ragchew with the Far East on 10 meters in the middle of the day. But if it doesn’t measure up, so be it. I talked to plenty of guys all over the world at the yawning chasm between the peaks, after all.

But most of all, I’d like to see everyone calm down a bit and not be so myopic. We see only a tiny slice of time in our own existence. Even so-called scientific observations are looking at a pitifully narrow slab of time and only a tiny bit of reliable data.

Put it into perspective before you panic and sell all your ham gear. Or before you stop gazing northward for a glimpse of the aurora borealis.

By the way, I checked. There is nothing we can do about the state of the sun’s surface anyway, so why worry?
