From the KX3 e-mail reflector (posted today). And this sounds very interesting:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Just a note to advertise a Special Event Station scheduled for 1600 UTC to 2400 UTC on 19 September 2012 – a hairbrained scheme launched too late to meet the printed matter deadlines.

Further details at www.qrz.com under call sign K2N. Bottom line: An eight (8) hour QRP CW-only special event aboard the only floating American WW II destroyer escort in the world that has been restored to its original 1945 wartime condition. We will operate two – possibly three – barefoot Elecraft KX3 transceivers and our antennas will consist of the authentically restored maritime verticals and horizontal wires. That means 70 and 80 foot wire verticals on the port and starboard sides; 100 and 190 foot long wires running amidships toward the fantail. We’ve already run a test and the KX3 internal ATU loads to 1:1 with no complaints whatsover on 40 through 6 meters inclusive. Our counterpoise is to die for — a 1200 ton navy warship floating in the Hudson River at the Port of Albany, New York.

If everything goes according to plan, we also expect to have pre-production versions of the new Begali “Adventure” paddle to field test. Two iambic paddles and one non-iambic mono version. The “Adventure” is designed to mate directly with the KX3 – or – sit in its base for use with any other transceiver.

So, if you are interested in working an historic ship then please mark your calendar as per www.qrz.com. We will QSL as per www.qrz.com with a nice postcard of the USS Slater (DE-766).

That’s the middle of the week – on a Wednesday.  But they will run until 8:00 PM that evening, so I stand a chance after getting home from work.  I would like to nab this one!

QRP – When you care to send the very least!

I was playing around on 30 Meters and 40 Meters tonight, listening, tuning, calling CQ.  I had a very FB QSO with Rudi W8DJ on 30 Meters, where the signals were plentiful and loud.

After our QSO, I hopped on over to 40 Meters and heard a weak; but perfectly copyable CQ from VA3IED/QRP near 7.030 MHz.  So I decided to throw out my call, and sure enough, I got an answer.

The op’s name was Scott, and he told me that he was on a camping trip to a remote island in Canada. Alarm bells immediately went off in my head!  I remembered seeing a video on YouTube about something like this!  I asked Scott if that was him and sure enough, it was!

Scott is back to the same island – canoeing out there and having a grand old time camping and playing radio, QRP style that is.  Last year’s video told the tale of his PFR3A. This year it is Scott’s new KX3 that has accompanied him.

During our QSO, he was about 539 and I got a 529 in return.  Not the strongest of signals; but very easily readable nonetheless.  As I sit hear typing this, Scott is in conversation with another Ham after taking a short break after our QSO.  I don’t know if it’s changing band conditions; or if he re-oriented his antenna, because he is an honest 579/589 into NJ now.

This is last year’s video; so you can see where he is camping.  It sure is beautiful, that’s for sure. I didn’t ask Scott; but sure hope he’s shooting more video this year, showing off his KX3!

QRP – When you care to send the very least!

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.

KX3 #110 has had a problem ever since I received it. The audio through the speaker has always sounded badly distorted and buzzed at anything above a very low volume. Judging by comments in the KX3 Yahoo group this was not an uncommon problem. A couple of solutions were proposed, including removing the cloth between the speaker and its grille. As I could get perfect audio on headphones I decided to wait until the definitive solution was published and until I plucked up sufficient courage to take a screwdriver to the radio.

KX3 #110 awaits a replacement speaker

I opened the case and poked around with a finger to see if I could find what was vibrating. The buzzing was definitely coming from the speaker area so I concluded that the problem was the speaker cone vibrating against the grille cloth. I posted a message on the KX3 Yahoo group to see if I could determine the chances of a successful cure if I removed it. The replies suggested that the prospects were good. I also received an email from KX3 Support offering me a replacement speaker. Excellent customer service!

This morning I was feeling brave so I opened up the case and tried to remove the speaker. I took out the 4 screws but the clearances around the speaker are so tight it looked as if I might have to take the KX3 to pieces to remove it. With a bit more jiggling it came free (phew!) so I partially reassembled the two halves with the speaker poking out the front of the radio. I applied power and attached an antenna and various howling and squawking noises emerged from the speaker.

So the culprit really was the speaker! Perhaps it had been damaged during assembly (not by me, as this was an assembled radio.) I told KX3 Support that I would have to take up their offer of a replacement speaker. The KX3 will remain in two halves until I receive and install it.

I had a real good time during the 1st Annual Skeeter Hunt today, although the outlook appeared bleak from the very beginning.  Just as I was heading out the door to go to the park, our vacuum cleaner decided to give up the ghost.  It made a real funny noise and a burning smell.  I tried troubleshooting it quickly; but it turned out we needed a new one.  Of course, my XYL didn’t want to wait; so it was off to Target to buy a new one.

That chore taken care of, I headed to the park (dressed in my WGØAT “Old Goats Rule – QRP Adventures” T-shirt!) – nearly an hour and a bit into the contest.  Fortunately, everything after the vacuum cleaner incident went as smooth as butter!

The weather here in Central NJ was gorgeous!  A high of about 84F with sunny, blue skies and lots of white, puffy clouds.  The humidity was not bad, and the only Skeeters that I had to worry about were the ones on the airwaves.

The wrist rocket got a line up over a pretty high tree branch on my first attempt.  The PAR antenna went up without any trouble at all and and didn’t even cause the KX3’s autotuner to even so much as burp – 1:1 SWR on both 20 Meters and 40 Meters.  The little box to the right of the KX3 is the PAR matchbox.  I used my Whiterook single lever paddle today.  And of course, you can see Ol’ Blue, my battery, up there in the upper left hand corner of the camping table.

And the good SWR on 20 and 40 was a very good thing, because unlike the Flight of the Bumblebees, I was to find a lot of activity on 40 Meters.  In fact, a little after 20:00 UTC, 20 Meters became dominated by European stations and I was barely able to hear any Skeeters on that band after that point.

In all, I managed 28 QSOs – 13 were on 20 Meters and 15 were on 40 Meters.  Best DX was working Mike DJ5AV from Germany on 20 Meters at 18:55 UTC.  I only got a 529 from him; but there were a lot of strong signals on both bands and I received quite a few 579s to 599s in addition to the “normal” 559s.

Tear down was just as easy as set up.  After the contest ended, I was able to pack up things and be out of the park in less than 10 minutes.

I would like to thank all of you who took the time to participate in this first ever NJQRP Skeeter Hunt.  I think a good time was had by all; and this will definitely become an annual Summer QRP event.

Remember, logs are due by September 12th, after which I will post results.  Log summaries are fine – details of each QSO are not necessary – but if you want to send a log in that way, that’s OK, too!  And any pictures, especially those of you who home brewed keys for the event will be greatly appreciated!

I’ve gotten a few logs in already and I hope to get many, many more.  In fact, Jim W1PID, posted another of his great stories today – this one about the Skeeter Hunt:
