Over on the Elecraft KX3 Yahoo group an argument has been raging as to whether running low power into a tower-mounted beam is QRP. Some folk feel that QRP also means using simple no-gain wire antennas. Others argue strongly that using an antenna with gain is a perfectly valid way to do more with less, that “less” relates to power and nothing else.

On his QRP – Do more with less blog, Larry W2LJ nails his colours (colors?) firmly to the mast. Saying those who use towers and beams aren’t QRP is baloney, claims Larry.

Personally, I think QRP is whatever the ARRL, G-QRP Club, QRPARCI or CQ Contest committee says it is. If you are competing in one of their contests or applying for one of their awards you must follow their rules. And the only limitation they specify for the QRP category is power level. So I don’t think it is possible to win an argument that QRP includes any other restriction besides low power. But I can understand why some people feel that those who have a lot of aluminium in the air have an advantage over those who only use a piece of wire and that lumping them into the same category is unfair.

To really put the cat among the pigeons does the spirit of QRP include the use of store-bought or kit-built equipment too? I certainly feel that the art of QRP is strongly allied to the practise of home-brew, but I still claim to be QRP when operating my FT-817, KX3 or K2. Should the ham who operates an Elecraft KX3 belong in the same class as one who uses a two-transistor Pixie?

Perhaps we need a new term to define this kind of minimalist operation?

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.

Daunting, isn’t it?  Just goes to show that there were some superb ops up there on CY9M!

QRP – When you care to send the very least!

I kept the radio tuned to 20 Meters for the evening and had a variety of QSOs.

The first was with CO6RD, Reynaldo in Cuba.  This wasn’t a long QSO as Reynaldo was working “contest style” racking up the QSOs. But I did get him on the first shot, even though a lot of stations were calling.

Next up was a busted QSO with Mike AA6WQ, who was operating from TN.  We got through the QSO basics, only to have the band pull the rug out from under us.  One minute we were going at it, next minute we couldn’t hear each other anymore. I guess that’s the way the cookie crumbles, sometimes.

With two short QSOs under my belt, I was thinking that might be how the evening was going to go. But my fears turned to be for nothing as the next QSO was an almost hour long rag chew with Paul W4KLY in Stone Moutnain, GA.  This was an Elecraft to Elecraft QSO.  Paul was using his K1 and (of course) I was on the KX3.  QSB had a role to play; but in all honesty, when the band was not in fade mode,  our signals were 599 both ways.  We talked about rigs, portable ops and antennas and summer vacation plans.  It was very enjoyable and it is truly amazing to see how fast an hour can go by on you when you’re having fun.

The last QSO for the night was with Rumi LZ2RS in Bulgaria.  He was calling “CQ QRP” and I was lucky enough to be heard on my first call.  Rumi was at 5 Watts; but what really made the QSO was his Yagi at 12 meters up, pointed my way.  I was on the 88′ EDZ pumping out 5 Watts from my end also.  Signals were a legitimate 559.

The bands have been so good lately!  Not the best I’ve ever witnessed; but after the past few pitiful years, this is like Heaven (comparatively).  I sure hope it stays this way for a while and doesn’t take a fast dive off a cliff into oblivion.

On another note, this new 9 cell battery that I got for the Acer is fantastic!  I got it Monday and attached it to the netbook for charging.  I’ve used it Tuesday, Wednesday, and tonight – about two to three hours per night.  The indicator says it still has about another two hours left in it.  Of course, I have Windows set for “Max Battery Life” through the control panel, but even so, this is way outlasting the old battery.  That one gave me about two hours computer time, tops.  This battery should be able to get me through a four hour sprint (outdoors) without breaking a sweat.
