Cathy, Yes there is a simpler way to do that! That way is called Spectrogram - an audio spectrum analyzer that runs on a Windows computer (there are others that will work on other OS's, but doesn't everyone run Windows <G>).
You can download version 5 of Spectrogram from Tom Hammond's website www.n0ss.net - while it is not the latest version, it is free and will do much more than the task required to get your K2 filters correct. Tom also has some instructions for using Spectrogram to set the filters on his website and also at the Elecraft site in the Builder's resource page. You may still want to record your transmissions and then make small alterations to achieve the voice response you desire, but if you rely on another receiver, make certain both the other receiver and the K2 are showing the correct frequency - you can check that by tuning to WWV at 10 MHz. You may also need to do a good job of setting the dial calibration. You can find instructions dealing with accurately setting the reference oscillator and completing the dial calibration and filter alignment in the K2 Dial Calibration article on my website http://w3fpr.qrprqdio.com . 73, Don W3FPR > -----Original Message----- > > I have just finished building and installing the KSB2 in K2 #5191.
