Thanks Don and others for referring me to the CW bandwidth mod (wave shape mod). It shows the fine waveform of the K2. Mine is ser. 4662 and has that mod. I am by no means complaining about the waveshape - it is superb. I am only complaining a little bit about the inability to reach 50% weight. It is quite close and maybe acceptable to most operators and for me it is only a problem at QRQ.
I have asked many times, but nobody has yet answered my simple question of what the minimum weight should be (when set to 0,9). 73, Paul OZ4UN -----Oprindelig meddelelse----- Fra: Don Wilhelm [mailto:w3...@embarqmail.com] Sendt: 20. april 2011 18:08 Til: Poul Erik Karlshøj (PKA) Cc: d...@w3fpr.com; elecraft Emne: Re: [Elecraft] key dot weight Just go to the Elecraft website www.elecraft.com and on the left column, click on Manuals and Downloads, Then select K2 - on the list that opens, find "K2 Keying B/W Mod" and you will have it. 73, Don W3FPR On 4/20/2011 11:33 AM, Poul Erik Karlshøj (PKA) wrote: > Hi Don > Where do I find "the K2 Keying Waveshape Mod instructions"? > Been looking at "Official (and unofficial)modifications for the K2" and also > your fine web page, but I did'nt find anything about the internal keyer. > Can you send me a link? > 73, Paul OZ4UN > > -----Oprindelig meddelelse----- > Fra: Don Wilhelm [mailto:w3...@embarqmail.com] > Sendt: 20. april 2011 14:12 > Til: Poul Erik Karlshøj (PKA) > Cc: elecraft > Emne: Re: [Elecraft] key dot weight > > Paul, > > I suggest you compare your keying waveshape to that shown in the K2 Keying > Waveshape Mod instructions.
