Re: [Elecraft] K2 and KX3 with A/B switch

Hello Don, thanks for your attention. I measured the power output meny times with two different meters, one with PEP function and one without. In both cases i can see the differences between the K2 and the other radios. On the same meter where i read 60-70 watts with the K2, i can read 90-100

Graziano, How are you measuring the power output in SSB? If an external wattmeter, you are likely driving it to full PEP power. I test the SSB operation on each K2 I repair to be certain the PEP is the same as the CW response at full power. I use an oscilloscope to determine that. An

Thank you for the comments. The pop goes away with AGC OFF. It also goes away with AGS PLS set OFF. Perhaps PLS OFF will be my new default setting, unless in heavy QRN. Now, I will have easy time partying with K2. BTW, it goes to Z35M, who should be "Elecraft hero". He made about half a

Hello, My KX3 doesn't show the problem you describe, maybe you need to give a look to your settings, but you already received some answers from the major experts. I also own a K2 full optional and i think is the best radio for CW, the K2 have the best signal/noise ratio i ever heard and the

Ignacy, I’ve never noticed the KX3’s AGC pumping, so I suspect something else. Small speaker aside, it should sound every bit as good as the analog K2, just with additional filtering features (thanks to the KX3’s DSP). Try turning AGC off. If there really were pumping, this would stop it. If

The KX3 AGC is very similar to the K3 AGC. Take a look at the "Noisy K3" article on my website for some relief. The KX3 and K3 threshold and slope numbers may not match, but can be a guide for obtaining the settings that are best for your type of operation. See www.w3fpr.com. 73, Don W3FPR

[Elecraft] K2 and KX3 with A/B switch

I am going to sell my K2 as it is gathering dust since KX3 came on board. But for probably the last time I put them on the A/B switch. Here is what I have found. 1. K2 has good speaker. KX3 has lousy speaker. Nothing strange as K2 is bigger. For comparisons I attached KX3 to an external
