I am feeling pretty good about the numbers Rob Sherwood, NC0B, has come up with. That is my radio he is testing and so now I know exactly the specifics of that particular radio, SN 00149. It was a kit radio that I built, Elecraft checked it out, finished the calibration procedure, returned it to me and I lent it to Rob. He will have it until the end of next month so he will be able to make experienced comments about the K3 in general including in depth operating experiences.
I am missing my radio but thrilled to participate in some small way in a test program that I am sure is standing the rest of the radio manufacturers on their collective ear! In the meantime, I am having fun with my K2, especially with all the new countries that have been or are on the air now! 73, Charlie, W0YG..>> |

After all, that's the radio all of >us who purchase the "kit" will be using; not one possibly tweaked by the factory. I will post the answer here so everyone can share in exactly what happened. I was building up the radio and started final calibration. Before finishing calibration, I was anxious and listened on 160M where I heard my neighbor all across the band. I called Elecraft and asked if this was normal. Rather than farmer around, they said send it in. They gave me a return number and so I sent it in. I explained I had not finished calibration but they said they wanted to check it anyhow. I sent the radio in and they gave me the info back that I hadn't finished calibration, that they found nothing wrong. Hey I said, I told them I hadn't finished calibrating but since I knew it was going to NC0B, I was more than happy to send it in. To make a long story short, and you can check with Wayne or Eric on this, they finished calibration and shipped it back. Apparently I had stopped on the step where it is critical to calibrate the synthesizer, duh. Anyhow, Elecraft took care of the catch 22 problem for me and all is/was well. I immediately checked it on 160M when it returned and I could get within 800 Hz of my legal power running neighbor before his transmitted phase noise precluded going closer. I waited a few days until Rob and I could meet in the city and passed it on to him. Now he has the radio and is putting it through its paces. If you want to know more, I suggest you contact either Wayne or Eric or Rob as the case may be however Rob has pretty much finished his testing and published his results. That is what started all this discussion in the first place, the K3 is at the top of the list! That's my story and I am sticking to it! 73, Charlie, W0YG..>> |

Charlie,
I am sorry to hear that Rob Sherwood's K3 test was performed on a rig that may or may not be representative off all K3's. It would have been best if Elecraft had not done any work on it or made any adjustments to it once it was built by you. Chances are what they did to it did not have any affect on its performance but we will never know. I hope you will like your #149 as much as I like my #148.

The K3 that Sherwood tested would certainly be representative of the factory built units. Further, if as claimed, user alignment ca be done to the same level as the factory without any specialized test equipment, Sherwood's numbers would be representative. Finally, since the test was performed with 5 pole filters, some units may well have better numbers than the one tested. To arbitrarily dismiss this test as non-representative smacks of a troll. 73, ...

>To arbitrarily dismiss this test as non-representative smacks of a
>troll. No it doesn't. This is exactly the reason why the ARRL buys a rig and doesn't accept product from manufacturers to test. If you know what is going to be tested for you can make sure to tweak and tune for those specs and/or even worse you can make non representative samples. When I was working in the car audio industry we used to read reviews all the time about amps that measured out at whatever power. Then we'd buy one and find out that it only did 70% of what the magazine reviewed it to do. After calling the magazine and asking them about their test methods we got to talking and they tore the amp apart and found out that the amp they had and the one we had was loaded with different output FETs. Did Eric and Wayne do this? I highly doubt it! But did they make sure that the thing was tweaked and tuned as well as they would have their own personal rig? You bet they did! Did they do a better job than joe blow who's putting together the kit? Probably a lil because they probably have access to better equipment and they know and the tips and tricks to eek out every bit of performance. Are we talking much? No probably less than a dB of difference between the unit but its still slightly different than just coming from the hands of the owner directly. That's all he was saying. He wasn't dismissing it just slightly questioning it. Then in the same breath said it was a fantastic radio! _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Easy enough to solve. Just send your radio in for a retest.

If anyone is in doubt, I suggest they wait another 5 years...especially if they are competing against me in contests. ;-) 73, Bill W4ZV |

Sorry I brought this up. I never intended for this to be a flame thread or argumentative thread. My point is:
ELECRAFT DID NOT SPECIAL TUNE MY RADIO! You finish the calibration and your radio should perform exactly the same. Others independently have verified Rob Sherwood's results. Instead of checking with me, as I indicated before, please verify this with Eric or Wayne. Then you will know too! 73, Charlie, W0YG..>> |

> No it doesn't. This is exactly the reason why the ARRL buys a > rig and doesn't accept product from manufacturers to test. Well, the K3 that ARRL is testing is a factory built radio. In all probability it will be identical in every way to the one that the factory aligned and Sherwood is testing (except that the first ARRL test radio will be a 10 watt version). When a given product is available only from the manufacturer there is no way that they will not get one identical to all of the other factory assembled and tested units. On the other hand, what's different about a factory aligned radio than the entry for the Icom 765 that says: "m Receiver was optimized by Malcom Technical Support for best dynamic range" - or for that matter if Sherwood were to test any other radio that had recently been aligned the manufacturer or manufacturer's service facility? We're not talking about a custom K3 here ... it's a customer radio on which the final alignment was done in Aptos. There is no reason to cast doubt on the validity of Sherwood's tests. If anyone wanted to make the test results better, they would have been done using the 8-pole filters supplied by Elecraft and not the 5-pole customer filters in the radio. 73, ...
