I’m not doing much radio today as Olga and I celebrate our 10th wedding anniversary.

Some of you might like to see a picture of us taken today in our present to each other – a new kitchen!

Thank you, Olga, for a wonderful ten years. I hope the next ten will be even better!

Arghhhh!

With 16 Fox hunts completed, I was 10 for 16.   If I was in the major leagues, that would be a .625 batting average and I’d have mansions, yachts, and sports cars.

But alas, it’s JUST the QRP Fox hunts; and in the last two weeks, I have been shut out!

To make matters worse, tonight’s hunts are the last of the Summer 2012 season, so I will be going out on a really lousy note. I’m doing about as well as Mr. Fox shown above, who got stuck in the fence that surrounds my cousin’s house in Pennsylvania.

A revoltin’ sitchyashun!

The Colorado QSO Party will be held this Saturday September 1, from 6 AM to 10 PM Mountain Time. This is a fun radio contest where amateurs outside of Colorado try to work as many Colorado stations as possible.

It looks like we will have quite a few counties on the air for this event, so it will be a good opportunity to work any Colorado counties that you might be missing. Complete rules are available here.

Thanks to the Pikes Peak Radio Amateur Association for sponsoring this event.

73, Bob K0NR

The setup at the park

Last weekend on Saturday the weather here was great lots of sunshine and very few clouds. So it was off the the park with the radio to give the ARCI welcome to QRP contest a go. Its a 3 hour contest from late morning to early afternoon. I setup my Elecraft K2 along with my mono band mobile whip antennas. The key I used was the Mini Palm paddle which works great and has a super feel to it. I found the bands to be in good shape but was not able to find many who were participating in the contest. In total I made 3 contacts contacts in 2.5 hours of operation. While operating I did hear W6/DL6AP/P who was operating in the SOTA at location CT-086....translation Strawberry peak in California. I was not able to contact W6/DL6AP/P but I did hear him in there. There was some other very attended State QSO party contests going on at the same time and were very well attended. So over all I did not strike it rich in the contest by any means...BUT.......I did pickup some bonus points for just being portable on battery power with a portable antenna.

Ever since I received the Elecraft KX3 it has suffered from poor loudspeaker audio. It buzzed and distorted at any but the lowest volume level. Various suggestions were made and considered but the culprit seemed to be the loudspeaker itself. Elecraft spotted my description of the problem on the KX3 Yahoo group and offered to send a new speaker. After confirming to my satisfaction that the speaker was indeed the culprit I accepted the offer. The replacement came in the post this morning.

The culprit(s) revealed

It didn’t take long to plug the new speaker into the KX3. To my dismay, that buzzed and distorted too. It didn’t seem to be quite as bad as the original, though, so I decided to install it. That was when I hit a snag: the holes in the speaker chassis had not been tapped to take the mounting screws. I was stymied.

Thinking I would have to put the old speaker back, I had a good look at it. That’s when I noticed a split ring lock washer stuck to the magnet where it joined the speaker cone. Aha! I thought. The culprit! As I was soldering the speaker leads back on I noticed something else that should not have been there. A second lock washer! I fished it out with the end of a jeweller’s screwdriver and put it with the other one.

I hoped that would be the solution and prepared to reinstall the original speaker. While I was thinking about that I was examining the replacement I had been sent and I noticed what looked like the edge of another split ring lock washer. After a bit of fiddling with the jeweller’s screwdriver I managed to fish it out. Yes. it was a split ring lock washer, stuck to the magnet of the replacement speaker!

I’m sure some of you are thinking that my shack must be a tip with bits of hardware strewn all over the place, but I assure you that isn’t. I can easily see how a small part could get dropped inside the KX3 during assembly and migrate to the speaker’s powerful magnet. But how one came to be stuck to the inside of the replacement in a sealed envelope straight from Elecraft will probably forever be a mystery.

I’m happy to report that the audio from the KX3 is now perfect at any reasonable volume, with the original speaker reinstalled in it. If any UK KX3 owner needs a replacement speaker then it’s yours for the asking. But you’ll have to tap threads for the mounting screws into it.

I am so happy to see that Jim W1PID’s outdoor QRP adventure stories have now been picked up over at AmateurRadio.com, which is a great site, by the way.

Since Jim’s posts will be picked up there, I would ask you to keep an eye out for them and will no longer mention them here, in order to avoid a duplication of effort.

If you’re into QRP and the outdoors, or would like to be, or find yourself forced to live vicariously, please treat yourself to Jim’s sagas.  If you’d like to re-read an old story or catch up on a few you might have missed – here’s Jim’s Website:  http://www.w1pid.com/

Happy reading!  And Jim, thanks so much for sharing.
