Yes last contest i used winkeyer k1el and n1mm with correct settings on winkeyer cw sound good

I replaced the transistor circuit with one of those K1EL winkeyer kits, and it still sounded choppy, but I had read an article on the web somewhere about switchover delays in the KX3. The author of that article recommended a particular value for the fixed delay compensation parameter in the Winkeyer, and when I configured that, the CW sounded FB. It is quite possible that some tweaking of the internal keyer code in the KX3 could produce some improvements, but so far I haven't made any measurements myself to investigate this topic. 73, Matt VK2RQ On 22/08/2013, at 5:13 PM, Klaus Koppendorfer <[email protected]<mailto:[email protected]>> wrote: Tnx Mat, yes i know this article – measurements are done with 20 wpm With higher speeds it will become more worth !!

Keying with 30wpm and more the dot-dash ratio is incorrect - very short dots like a machine gun :) Compared to my k1, kx1,k2 and k3 the cw from internal keyer of kx3 is terrible Dick, do you think there will be a solution in firmware soon ?? Vy73 Klaus Oe6kyg Elecraft does not use separate keyer chips. Morse code generation is performed by the main microcontroller. Dick, K6KR Since I am interested in the Ultimatic mode and the Bug mode I have on my Pico keyer, can anyone tell me (I am mostly concerned with the KX1 and also the KX3 keyer chip): 1) Do the Elecraft keyer chips have these modes? 2) Is the Elecraft keyer keyer chip (drop-in) upgradable to a Pico Keyer chip?
