Re: [Elecraft] R: Re: K3S losing swr-wattmeters indications on tx - please help

Yeah, that's kind of how I've always thought of it, a "user is responsible for debouncing" type of thing. Especially the Dah paddle and my Kent straight key, when bouncing, may not be indistinguishable from a straight key going 100wpm as far as the rig is concerned LOL. So I never really thought

Odd ... I operate almost exclusively CW at 20 - 40 WPM with both a K3 (#0056) and a K2/100 (#5665) and have never experienced the problem you describe. FWIW, the K3 has been heavily used in numerous contests by KE7X. 73 K0PP On Jun 20, 2016 10:52 AM, "glcazz...@alice.it"

I have heard numbers like 90 and 100 wpm for operative QRQ for the K3, but don't have time to go research where I heard that. I *know* it runs sweet at 60 and 70 WPM. BTDT. But I will caution that certain problems with key contact surfaces will produce a signal impossible to debounce. These

Re: [Elecraft] R: Re: K3S losing swr-wattmeters indications on tx - please help

I imagine it's because of the QRQ support that it doesn't have dedicated debouncing circuitry for straight keys, but I'm not sure about that. The K2 does have some small caps across the key input, but it too still gives me slight problems when I key it with my straight key. Though it's not as bad

Lucien, many thanks for your help. I am ashtonished. It is incredible that a great rig as the K3S doesnt have the simpler debouncing circuit on the key input, input obviously available for all mechanical kind of key, so with potential bounces. This afternoon I have written to elecraft support
